Backend Developer (Node.js, Typescript)
Skills
About the role
Hi,
Immediate hiring for Singapore
Must-have
Strong backend engineering experience in Node.js / TypeScript. Track record of owning services end to end in production - not just shipping features to a spec.
Comfortable across the stack. Able to pick up frontend work in React when the ticket calls for it, even if backend is your primary strength.
Solid API design skills. Familiar with authentication and authorisation patterns (OAuth and similar) and production debugging.
Familiarity with observability practices - logging, tracing, metrics. OpenTelemetry or equivalent experience preferred.
Conceptual fluency with LLM agent systems: tool calling, context windows, streaming, non-determinism. Enough to make sound architectural decisions in this domain. No ML or model training background required.
Comfortable with ambiguity. This team is small. You will often decide how something should be built, not just execute a spec.
Nice-to-have
Hands-on experience with agent frameworks or protocols (LangChain, Google ADK, MCP, A2A, or similar).
Cloud infrastructure experience (AWS).
Background in platform or developer-tooling engineering - building for other engineers as your primary customer.
Interest in AI security: prompt injection, guardrails, and safe agent execution are real parts of this backlog.
