About Ministry of Sustainability and the Environment (MSE)

At Ministry of Sustainability and the Environment (MSE) and our family of agencies – PUB, NEA, and SFA – we drive sustainability and resilience initiatives that improve the everyday lives of Singaporeans. As part of the MSE Family, you will be at the forefront of innovation, leading efforts to safeguard water resources, protect public health, and ensure food safety. Through partnerships across sectors, we tackle evolving challenges while fostering an inclusive, safe, and supportive workplace. Join us in shaping Singapore’s sustainable future and making a lasting impact on the everyday lives of generations to come.

At MSE, we are always on the lookout for high performing individuals who share our aspiration of making Singapore one of the world’s best living environments. We are building AI products and shared platform capabilities that can improve how we run complex operational workflows.

We are hiring software engineers who can take ambiguous problems from brief to production. This is not a pure research role and not a demo-building role. The work is to build reliable, maintainable, policy-sensitive AI systems that can survive real users, real operational constraints, and public-sector trust requirements.

AI will support how we build. Engineers still own the design, judgement, quality, and consequences of what ships.

How we build
We prefer simple, durable engineering choices over novelty for its own sake. The stack may vary by product, but the principles do not: clear architecture, automated testing, CI/CD, observability, secure-by-design delivery, and systems that are easy to reason about after launch.

The team’s operating model is product-led and platform-amplified. Product squads prove value in workflows; shared platform capabilities make those products observable, testable, governable, and reusable across MSE Family. Engineers may work inside a product squad, on the shared AI platform, or in a forward-deployed model where they help a vertical team build AI capability before bringing reusable patterns back to the centre.

[What you will be working on]

• Design, build, test, deploy, and operate AI-enabled products and platform components across MSE Family.

• Work on areas such as LLM integration, agentic workflows, evaluation harnesses, observability, guardrails, model access, retrieval/memory patterns, and multimodal AI use cases.

• Take ambiguous operations problems and turn them into maintainable software with clear success metrics.

• Build production features for products such as automation, tools, assistants, and deterministic and agentic workflow.

• Work with geospatial technologies and spatial datasets to build AI-enabled solutions that use location, environmental, asset, sensor, or other spatial information.

• Create engineering patterns that other product teams can reuse, including templates, playbooks, test harnesses, and reference implementations.

• Work closely with product managers, designers, data scientists, governance colleagues, and business owners.

• Use AI coding and development tools to accelerate delivery while retaining human accountability for design and quality.

• Participate in design reviews, code reviews, incident response, and technical decision-making.

[What we are looking for]

• At least 8 years of relevant working experience in fields related to artificial intelligence, machine learning, data science, or software engineering

• Completed at least one hands-on AI development and deployment end-to-end project.

• Strong software engineering fundamentals: system design, testing, version control, CI/CD, observability, security, and maintainable code.

• Good engineering judgement: you can explain trade-offs clearly and defend a technical position without becoming attached to it.

• Comfort with ambiguity: you can move from unclear policy, or operational needs into a working product shape.

• Appetite for AI-native engineering: LLM applications, evaluation, agentic workflows, RAG/memory, multimodal models, or AI-assisted development.

• Pragmatic taste in technology: you choose boring, durable tools when they are right, and newer AI tooling only when it genuinely improves the system.

• Ownership mindset: you do not stop at prototype handoff; you care about deployment, monitoring, user feedback, and maintainability.

• Ability to work with non-technical stakeholders in public-sector domains.

• Bias for measurable quality: you care about evals, regression checks, traceability, and evidence before scaling.
  

Nice to have

• Experience building production LLM or AI-enabled applications.

• Experience with evaluation frameworks, prompt/context engineering, model monitoring, or AI safety guardrails.

• Experience with Python, TypeScript, Go, PostgreSQL, containerised deployment, cloud services, or government/cloud-restricted environments.

• Experience building internal platforms, developer tooling, or reusable engineering kits.

• Experience working with geospatial technologies and datasets, including integrating, processing, analysing, or building applications using spatial data.

• Familiarity with Environment Domain, public-sector operations, procurement, or high-trust digital services.
  

What success looks like

In the first 6 months, you should have shipped meaningful production work in at least one product or platform area, improved the team’s engineering quality bar, and helped convert one-off AI delivery into reusable capability.

Why this role matters

AI work is moving beyond experiments. The next challenge is to make AI useful, safe, measurable, and maintainable across workflows. This role is for engineers who want to build public-good AI systems with national-scale relevance, while shaping the operating model for how product teams use AI responsibly.

What we offer you:
