HireLoop — Job Application Platform

Overview

HireLoop is a mobile job application platform we designed and built as a product. Most job apps concentrate on search; HireLoop concentrates on the moment of applying. A candidate can submit an application with a resume in one place, then continue the conversation with the employer without leaving the app. It serves both sides of hiring: the people applying and the employers receiving.

The Challenge

Applying for work is a chain of small frustrations. Candidates are pushed onto external forms, asked to retype what is already on their resume, and left guessing about pay until late in the process. Many give up halfway. Employers pay for that friction by losing capable candidates, and they struggle to keep follow-up conversations in one place instead of scattering them across email and phone calls. The product had to shorten the journey, be honest about the role, and hold the dialogue inside the app.

Who Uses It and How

A job seeker browses listings on a phone, often in spare moments, and wants to know the role, location and salary before investing effort. When something fits, they upload a resume from their device or cloud storage and apply. Later they check for replies. An employer or recruiter posts roles, reads incoming applications, opens attached resumes and replies to candidates with questions or interview invitations.

Our Approach

We began by removing steps. Applying sits on one screen, with document upload built in, so a candidate can finish the whole task in one sitting on a phone.

Transparency was the second decision. Salary and role details come first, letting people decide whether to apply before they start. That saves time on both sides because applications come from candidates who know the terms.

Third came direct messaging tied to the application, which keeps follow-up where the context is. We used React Native, Node.js and MongoDB.

What We Built

Job listings present the role, employer, location and salary clearly. From a listing, a candidate opens the single-screen application, attaches a resume and any supporting documents, and submits. Employers see applications together with attachments and can reply through the built-in messaging, so each thread is linked to the application that started it.

Architecture and Data

Entities include candidate profiles, employer accounts, job listings, applications, uploaded documents and message threads. An application connects a candidate to a listing and references its files, while a thread references the application. MongoDB's document model suits this data because listings, attachments and conversations vary in shape. Uploaded resumes are held in file storage and referenced by the application record. The Node.js service manages uploads, validation and messaging,.

Security, Privacy and Quality

Resumes hold names, contact details and work history, which is personal data. Files should be stored privately, retrieved through authorised requests rather than public links, and shown only to the employer the candidate applied to. Uploads need type and size limits and scanning where the risk warrants it. Candidates should be able to withdraw an application and delete their data, in line with regional privacy law such as GDPR where it applies. Testing covers upload failures on slow connections, application flows on different phone sizes, and permission checks so one employer can never read another's applicants.

Technology

React Native gives one codebase for iOS and Android. MongoDB fits variable job and message data, and Node.js keeps the stack in one language, which simplifies development and maintenance.

Outcome

HireLoop makes applying a short, clear task and keeps candidates informed about what a role offers. Employers receive applications together with a channel to talk to applicants, and the structure supports later additions such as application tracking, saved searches or employer dashboards.

Frequently asked questions

How much does it cost to build a job application app?

Cost depends on whether you need only the candidate side or both candidate and employer tools, the depth of search and filtering, document handling, messaging, notifications, an admin panel and any payments for job postings. Integration with an existing applicant tracking system can also add scope. A focused apply-and-message core is far smaller than a complete job marketplace.

How should a job app store resumes securely?

Resumes should live in private storage, be encrypted in transit, and be served only to authorised employers through short-lived, permission-checked requests. Candidates should have a clear way to delete their files and data, and access should be logged.

Why does a single-screen application matter?

Every extra page in an application form is a point where candidates drop out, especially on a phone. Collecting the essentials on one screen, using an uploaded resume instead of retyping it, reduces that friction and tends to bring in more finished applications.
