[What you will be working on]
We are seeking a Senior Software Engineer to lead an AI-Workflow product that allows officers to automate their work without writing code. As the lead, you will set the technical direction while staying hands-on across the whole tech-stack including React canvas to python execution engine.
As Senior Software Engineer of GovTech deployed at Enterprise Singapore, you'll:
Partner with stakeholders and users to prioritise and manage the roadmap towards the product vision and goals
Collaborate with Product Managers and Designers to shape the team’s technical and delivery goals
Own the product end to end across the full stack: the React/TypeScript workflow canvas, the Python (FastAPI) backend, the DAG execution engine, and the AWS infrastructure underneath it, managed as code with Terraform
Design and evolve architectures that meet stringent requirements for reliability, resilience, scalability and cybersecurity, including safely running user-authored code and high volumes of LLM calls
Build and operate LLM features in production: model integrations, structured outputs, prompt design, AI-assisted workflow generation, and managing latency, rate limits and cost
Work like a startup: move fast, ship often, talk to users directly, and pick up whatever the product needs, whether that is a feature, an incident, an infrastructure change or a user demo
Balance new feature delivery with technical sustainability, maintainability and risk mitigation
Bring strong technical judgement, helping engineers navigate design and architecture trade-offs in line with long-term goals
Ensure the team ships high-quality software predictably and improves over time through CI/CD, automated testing and observability
Monitor delivery health, reliability and tech debt, and address root causes, not just symptoms
Meet regularly with engineers to discuss their performance and professional growth, offering constructive feedback, mentoring and guidance
[What we are looking for]
Has strong experience building modern full-stack web applications, e.g. React, TypeScript, JavaScript and CSS on the frontend, and Python (FastAPI or similar) on the backend
Has hands-on experience with AWS (e.g. ECS/Fargate, EKS/Kubernetes, RDS/PostgreSQL, S3, IAM) and infrastructure as code with Terraform
Is comfortable with containers and CI/CD pipelines (e.g. Docker, Helm, GitLab CI)
Has built LLM-powered features in production, or is keen to; experience with workflow or orchestration tools (e.g. n8n, Airflow, LangGraph) is a plus
Must be fluent with AI coding tools such as Claude Code and Codex, and the practices that make them effective: giving agents good context and specs, breaking work into reviewable pieces, and rigorously reviewing and testing AI-generated code
Has a startup mindset: biases towards action, is comfortable with ambiguity, iterates quickly with users, and is happy to work across every layer of the product
Stays close to the technical details, whether through architecture reviews, design docs, code reviews or hands-on contributions
Brings clarity, helping the team prioritise, plan and focus in a complex environment
Understands how software systems…
