About Referec Ltd (Hong Kong)
Referec Ltd (Hong Kong) is a recruitment technology company developing an intelligent referral-driven hiring platform. The platform connects recruiters, candidates, and referrers through data-driven automation, real-time integrations, and AI-assisted matching. Our research and development work focuses on advancing recruitment intelligence through experimentation in scalable cloud architecture, intelligent data normalization, and AI-enhanced decision support systems.
All R\&D duties under this programme will be conducted primarily in Hong Kong under the supervision of the Chief Technology Officer (CTO).
Fullstack Engineer R\&D
Summary:
The R\&D Fullstack Systems Engineer will lead applied research into scalable software architecture, intelligent system behavior, and experimental feature design within Referec’s recruitment intelligence platform. This role bridges software engineering and R\&D leadership — defining hypotheses, leading experiments across multiple layers of the platform, and translating findings into architectural direction for the broader engineering team.
Key R\&D Duties:
Design and lead experimental studies to evaluate emerging fullstack technologies, frameworks, and architectural models for large-scale recruitment systems.
Research and prototype cross-layer optimization techniques (API, data, and UI) to improve scalability, reliability, and user responsiveness.
Develop and validate algorithmic methods for dynamic data synchronization and real-time system feedback.
Oversee experimental deployments in sandboxed environments to measure system performance under varying loads and data conditions.
Produce technical research documentation, benchmarking reports, and architecture recommendations for R\&D leadership review.
Mentor junior engineers in experimental methods, system instrumentation, and reproducibility standards.
Collaborate closely with the AI/Data team and DevOps engineers to integrate research prototypes into controlled R\&D environments.
Qualifications:
5+ years of experience in software architecture and fullstack systems design using Node.js, TypeScript, and React/Next.js or comparable frameworks.
Proven experience conducting or leading software performance experiments or architectural refactoring initiatives.
Strong analytical and experimental design skills, with the ability to translate technical uncertainty into structured research objectives.
Familiarity with cloud infrastructure (AWS or GCP) and containerized environments for experimental deployments.
Demonstrated leadership capability or ambition to take on an R\&D lead role.
Bachelor’s degree or above in Computer Science, Software Engineering, Information Systems, or a related STEM discipline.
