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 and engineering practices scale, and can guide improvements across architecture, testing, observability and infrastructure
• Believes in shared success, and collaborates openly across functions, domains and agencies
• Takes ownership of outcomes, and holds the team to a high standard of quality, security and delivery

Additional Job Description

• Bachelor's or Master's degree in Data Science, Engineering, Computer Science, or a related field (or equivalent experience)
• 7 to 10 years of experience in Software Engineering, at least 2 of which in a leadership capacity
• Proven ability to work collaboratively with cross functional teams
• Proven ability to work collaboratively with senior stakeholders and leadership
• Good communication and storytelling skills, with the ability to present findings clearly and persuasively
• Strong analytical thinking with attention to detail and ability to handle ambiguity.
