About the Role
We are looking for a Senior Full-Stack Engineer to become the dedicated technical owner of our internal HR Automation & Intelligent Operations Platform.
You will work directly with HR process owners and relevant Technology, Security, and Infrastructure stakeholders to transform fragmented HR processes into secure, reliable, and scalable digital workflows.
The existing platform uses React.js on the frontend and NestJS on the backend. Strong production experience with both technologies is essential. This role requires end-to-end ownership, from requirement discovery and solution design to deployment, monitoring, and continuous improvement.
Responsibilities

• Own the technical design, development, deployment, and ongoing reliability of the HR platform.
• Extend and improve the existing React.js and NestJS codebase using scalable and maintainable architecture.
• Deliver employee self-service workflows such as employment certificates, payslips, salary advances, contract renewals, asset requests, onboarding, and offboarding.
• Implement validation, approval, reconciliation, and audit controls for sensitive HR and financial processes.
• Design secure APIs, databases, integrations, and shared HR data models.
• Build People Analytics, workforce planning, recruitment, performance, and executive dashboards.
• Implement role-based access control, audit logging, data privacy controls, and appropriate security practices.
• Integrate the platform with existing HR, payroll, identity, and organizational data sources.
• Support staged data migration and module-by-module replacement of legacy or vendor-dependent workflows.
• Maintain engineering quality through automated testing, code reviews, documentation, CI/CD, monitoring, debugging, and production support.
• Work closely with non-technical stakeholders to translate business requirements into clear technical solutions and incremental releases.
• Track adoption, system reliability, data quality, and operational value after each release.
• Evaluate practical AI use cases that can improve HR operations without compromising security, privacy, or accuracy.

Requirements

• 4+ years of full-stack development experience, or equivalent evidence of end-to-end ownership of production applications.
• Strong hands-on proficiency in React.js, NestJS, Node.js, and TypeScript.
• Strong understanding of relational databases, data modelling, RESTful APIs, authentication, authorization, and system integration.
• Experience building workflow-based applications, internal platforms, or automation tools, with reliable validation, reporting, and sensitive-data controls, including role-based access, auditability, and secure development practices.
• Experience with automated testing, Git, code reviews, CI/CD, containerization, monitoring, and production troubleshooting.
• Strong problem-solving skills, an ownership mindset, and the ability to translate ambiguous requirements into solutions while collaborating with non-technical stakeholders.
• Professional working proficiency in English.
• Experience with HRIS, payroll, compensation, ERP, financial workflows, legacy or enterprise integrations, analytics dashboards, or workforce reporting is considered an advantage.
• Familiarity with secure AI-enabled workflows and automation is considered an advantage.
• A Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent professional experience, is considered an advantage.
