Full Stack Engineer (Fixed-Term, 12 Months)

About the role

Activate Interactive, a technology consultancy in Singapore, is hiring a Full Stack Engineer on a 12-month fixed-term contract. You will initially join a team building an AI-enabled platform for high-volume document processing, and may move to other teams as priorities change. Strong fundamentals and quick learning are valued more than past tooling.

Key responsibilities

• Design, build and maintain web applications, APIs, background jobs and database models.
• Turn real user and operational workflows into reliable software, working with product managers and operations teams.
• Integrate AI services (LLMs, computer vision, OCR) into product features, handling failures, cost and output quality.
• Write tested, typed and readable code, take part in code reviews, CI/CD and incident follow-ups.
• Contribute to system design discussions and document decisions.
• Pick up work across the stack, including integration or desktop work.
• Maintain systems, including API integrations with other government systems, and support security assessments, audits and compliance reviews.
• Depending on seniority, own the design of larger components and mentor junior engineers.

Required profile

• Solid full-stack experience: web front end (React), backend APIs (Node.js) and relational databases, with TypeScript as the main language.
• Ability to design a system within constraints and explain trade-offs.
• Working understanding of concurrency (threads, event loops, async/await).
• Habit of writing tests and using typed code, plus good practice in version control, code review and CI/CD.
• Familiarity with cloud basics: containers, managed services, object storage and job queues.
• Methodical debugging across system boundaries and clear communication with evolving requirements.

Required skills

• Hands-on experience with Node.js, React and TypeScript.
• Good to have: integrating AI/ML or LLM APIs, agentic workflows or MCP, Go/C#/Java, the Singapore Government Tech Stack, observability and runbooks, secure development, technical documentation.

What we offer

• Competitive market salary and a variable performance bonus.
• Medical coverage, life and health insurance, and flexible benefits or allowance.
• Wellness support, learning programmes, certification support and a staff development budget.
• Structured career pathways and a competency framework.
• Flexible work arrangements (flexi-place, flexi-time, flexi-load).
