Job portal app development: features, stack, cost, and how to launch

Job portal app development means building a two-sided product: an app where candidates create a profile and apply for jobs, a workspace where employers post jobs and review applicants, and an admin panel where you moderate jobs and verify employers. At Ronas IT, we build a job portal as a custom marketplace. The build covers one app for both sides, the admin panel, and the backend, and starts at $20,000 with a timeline of at least 8 weeks.

This guide covers where a new portal can still win against the big job sites, the features each side needs, how to split the work between web and mobile, the stack we use, how to get jobs into Google search, and the rules to check before AI starts ranking candidates.

What is a job portal app?

A job portal app is a two-sided recruitment platform: employers post jobs, candidates keep profiles, and the portal matches them.

This article is about the second type. The same approach works for a niche job board that later grows into a portal.

Can a new job portal compete with the big job sites?

Yes, if it does not try to be another general job site. Large job sites are hard to beat on broad searches such as “jobs near me”. A new portal wins a narrower group of employers and candidates by showing something the general sites do not: a license or certificate that matters in one trade, shift patterns, a language, a region, or a type of contract.

“Before you plan features, talk to employers who already struggle to hire through the big job sites and ask them why. Their answers show what your first version has to fix.”

Roman Surikov, CEO at Ronas IT

The hard part of any marketplace is the first months, when employers will not pay without candidates and candidates will not install an app without jobs. Three ways to get past this:

• Pick one side to win first: in a niche with few employers, sign them up by hand and let them bring their open roles; in a niche with many small employers, attract candidates first with a useful free profile.
• Start in one place: one city, one trade, or one type of shift. A portal with twenty good jobs in one area is more useful than one with two jobs in every area.
• Do some work by hand: post jobs for your first employers, call candidates, and check profiles yourself. Automate a step once you know it works.

Features a job portal app needs

A job portal needs a separate set of features for each of its three roles: the candidate, the employer, and the admin who runs the platform. The lists below are the features we recommend planning for. The first version does not need all of them, and the last part of this section covers what can wait.

For candidates

• Profile and resume: a short form that is quick to fill in on a phone, with an option to upload an existing resume, edit it later, or hide it from employers. Decide who can open resumes and contact details, and let candidates delete their profile and data.
• Search and filters: location, remote or on-site work, salary range, job type, and the criteria of your niche. Employer filters for candidates should use the same fields, so both sides describe a job in the same terms.
• Job alerts: push and email notifications when a new job matches a saved search.
• Quick apply: apply with the saved profile in one tap, with a cover note only when the employer asks for one.
• Saved jobs and application status: a list of jobs to come back to and a clear status for every application.
• Sharing: a link to a job that opens the same job in the app, which brings new users to the platform.

For employers

• Company profile: what the company does, where it works, and what it offers, so candidates can judge it before they apply.
• Job post templates: structured fields for requirements, duties, pay, and benefits instead of one block of free text. Structured fields also make filters and search results more accurate.
• Applicant pipeline: a list of applicants for each job with stages such as new, shortlisted, interview, and rejected, and notes the hiring team can share.
• Messages: a chat with candidates inside the platform, so neither side has to share a phone number before an interview.
• Billing: paid job posts, a subscription, or paid promotion, depending on your model.

For admins

• Moderation: a review queue for new jobs and employer accounts, so fake or misleading jobs do not reach candidates.
• Employer verification: a check of the company before its first job goes live, such as a business email, a company registry lookup, or a document upload.
• User management and reports: blocking accounts, handling complaints, and basic numbers on jobs, applications, and payments.

What can wait until after launch

AI matching, video interviews, resume builders, company reviews, and integrations with applicant tracking systems all add value, but none of them decides whether employers and candidates come back after the first week. Launch with search, apply, and the applicant pipeline, then add features in the order your users ask for them. If you want to test the niche before a full build, our MVP development service covers that first version.

A marketplace we built with a similar structure

We have not published a job portal case, but Docky, a marketplace we designed and built for clients from Malta, is also two-sided: berth owners rent out berths, and yacht owners find and book them. The list below covers only the parts of Docky that a job portal needs.

• Moderated listings: we built a moderator review for new berth listings before they were published. A job portal needs the same queue for new jobs.
• Identity checks: we added an identity check that users had to pass before they could rent or book a berth. In a job portal, employers go through a similar check of their company before their first job goes live.
• Chat: we built an in-app chat, which a job portal needs for messages between employers and candidates.

We built Docky with React Native, Next.js, and Laravel. The project covered two applications (a web app for berth owners and a mobile app for yacht owners), a landing page, and branding, with a timeline of six months. A working MVP was ready in the first three months. We kept adding features during the project, and its scope grew nearly threefold from the original MVP.

Web, mobile, or both?

A first version can be one cross-platform mobile app for both roles, with a web version added later if needed. For Docky, this would have been more practical, but the client specifically requested both a web app and a mobile app for the first version. Public job pages can still go on the web early.

Web pages do something an app cannot: public job pages can be indexed by search engines and become eligible to appear in search, which can bring candidates who have never heard of the portal. These pages can be served by the same backend as the portal's React Native app for iOS and Android.

One account or two?

Decide early whether one person can be both an employer and a candidate. Separate accounts are simpler to verify. One account with a switch between roles gives users more freedom but makes data checks harder.

We made this choice on an NDA marketplace for the UAE, where sellers need a trade license. Separate accounts would have needed more resources and given users less flexibility. After our tech team confirmed that one account was feasible, we built it: a user becomes a seller by uploading the license, a verification system checks it, and a manager can approve or reject it in the admin panel. A job portal can use the same pattern for recruiters who also look for work.

Tech stack for job portal app development

A job portal needs fast search over many jobs and profiles, real-time messages, push notifications, and an admin panel. The table shows each layer and the tools we choose for it. If your team already uses another stack, the same layers still apply.

One codebase for the iOS and Android apps keeps the experience the same on both platforms, and a later web app can share logic with it. We cover the web side in more detail on our web app development page.

How to get job posts into Google search

Mark up every public job page with JobPosting structured data, keep it accurate, and remove jobs when they close. The markup makes your jobs eligible for the job search experience in Google Search in the countries where Google offers it, and for a new portal it is a free way to reach candidates who do not know the brand yet.

• Required fields: Google's job posting documentation lists the required properties: title, description, datePosted, hiringOrganization, and jobLocation, plus validThrough for a posting that has an expiration date. The title must be the job title only, without salaries, dates, or company names. For a job that can or must be done fully remotely, Google asks for jobLocationType, and jobLocation is not required when applicantLocationRequirements is present.
• Closed jobs: jobs that no longer accept applications must be expired, for example with a validThrough date in the past or by removing the page. Google warns that failure to act on expired jobs in time may result in a manual action.
• Fast updates: for websites with many short-lived pages such as job postings, Google recommends its Indexing API instead of sitemaps, because it prompts Googlebot to crawl the pages sooner. Google still recommends submitting a sitemap for coverage of the entire site. The API works only for pages with JobPosting markup or livestream video markup. Setup takes a Google Cloud project with the API enabled, a service account added as an owner of the site in Search Console, and an OAuth access token. The default quota is 200 publish requests per project per day.

Build this into the backend from the start: the markup comes from the same structured fields employers fill in, and the API call goes out whenever a job is published, changed, or closed.

Matching and AI: what to check before you rank candidates

Start matching with filters and clear rules. Before AI ranks candidates, check whether you have enough real applications to judge it and which hiring rules apply in your market. Matching rules such as “same city, required license, salary inside the range” are easy to explain to both sides. An AI layer can then rank jobs for a candidate or suggest candidates for a job, for example by comparing profiles and job posts as vectors in PostgreSQL with pgvector.

“Decide in advance how you will notice when the model is wrong. Part of that is checking that it does not quietly push some groups of people down the list.”

Evgeny Leonov, CTO at Ronas IT

Hiring is also one of the areas where the use of AI is regulated. Two examples show what to look for:

• New York City: according to the city's consumer and worker protection department, Local Law 144 of 2021 prohibits employers and employment agencies from using an automated employment decision tool unless it has had a bias audit within one year, the audit information is public, and employees or candidates have received the required notices.
• European Union: Annex III of the EU AI Act lists AI systems intended to be used for the recruitment or selection of people as high-risk, including systems that place targeted job ads, analyze and filter job applications, and evaluate candidates. Under a 2026 amendment, the requirements and obligations for these systems apply starting on December 2, 2027.

Whether these rules apply to your portal, or only to the employers who use it, is a legal question. Ask a lawyer before launch, and design the matching so that you can explain and log how each ranking was made.

How much does job portal app development cost?

A job portal is a two-sided marketplace. At Ronas IT, a custom marketplace build starts at $20,000 and takes at least 8 weeks. It includes one cross-platform app for employers and candidates, an admin panel for moderation and verification, the backend behind them, and the design, project management, and testing. A web version for employers is a second platform and adds from $10,000. A larger scope costs more: Docky, the marketplace described above, had an agreed budget of $300,000-$400,000. After launch, mobile app maintenance keeps a mobile app working in the stores: bug fixes, updates for new iOS, Android, and React Native versions, and releases that meet Apple and Google requirements. Support for the whole system covers the mobile apps too: monitoring for outages, fixes for technical issues, and regular updates. The two plans are alternatives: app maintenance is for when only the app needs care, not an add-on to support for the whole system.

What moves the price of a job portal up or down:

• Roles: every extra role, such as a recruiting agency that acts for several employers, adds screens, permissions, and tests.
• Matching: filters and rules cost less than an AI layer that needs data, tuning, and checks for bias.
• Integrations: applicant tracking systems, video calls, and job feeds from other sites each add their own work.

What to do next

1. Name the niche and the side you will win first, and list what your employers need to know about a candidate that general job sites do not show.
2. Write the three role lists (candidate, employer, and admin) and mark what the first version cannot launch without.
3. Decide whether one mobile app for employers and candidates is enough for the first version, and whether one person can hold both roles.
4. Plan JobPosting markup and job expiry for the public job pages from the start.
5. Check the AI hiring rules in your markets before you plan AI ranking of candidates.
6. Ask for an estimate of the first version based on the three role lists, and budget for support of the whole system after launch, or for mobile app maintenance alone if only the app needs care.
