Essential Recruitment Technology Experience

Applicants should have previously worked on at least one substantial:

Job Board | ATS | Recruitment CRM | Candidate Database | Recruitment Marketplace | Job Aggregator | CV Search/Matching Platform | Recruitment SaaS Platform

General full-stack development experience without demonstrable recruitment technology experience will not be sufficient.

When Applying

Please provide:

1. Examples of recruitment platforms, job boards, ATS or recruitment CRM systems you have personally worked on.
2. Your specific role and technologies used.
3. Job-board, ATS, API or job-feed integrations you have completed.
4. Experience with CV parsing, candidate search or job matching.
5. Experience handling high-volume job/candidate data.
6. Links, screenshots, demonstrations or case studies where available.

Shortlisted candidates may be asked to review the existing platform and recommend an appropriate architecture covering job aggregation, candidate database development, ATS/CRM functionality, matching, external integrations, scalability and build-vs-buy decisions.

We are looking for someone who understands both the technology and how the recruitment industry actually works, and who can contribute to the architecture and future direction of the platform rather than simply following development instructions.

• Develop and maintain front-end components using modern frameworks and technologies to create intuitive user interfaces.
• Design, implement, and optimize backend services ensuring high performance, security, and scalability.
• Create and consume RESTful APIs to facilitate efficient communication between frontend and backend systems.
• Manage and optimize database schemas, queries, and indexing to ensure reliable and efficient data storage and retrieval.
• Integrate cloud services and third-party APIs to enhance application capabilities and performance.
• Collaborate with cross-functional teams including product managers, designers, and other developers to deliver high-quality features and enhancements.
• Write clean, maintainable, and well-documented code adhering to industry best practices and coding standards.
• Perform thorough testing and debugging to ensure the reliability and usability of applications.
• Stay updated with emerging technologies and industry trends to continuously improve development processes and software products.
• Identify and resolve performance bottlenecks and security vulnerabilities in software applications.
