The AI Programme at Singapore’s Ministry of Education (MOE) develops AI products and shared capabilities to support teaching, learning and the work of schools. Our teams bring together product management, engineering, design and data science to identify useful applications, test them with users and improve them through evidence.
Our work spans personalised learning support, feedback and assessment, tools that help teachers plan and carry out their work, and applications that improve school operations. We also develop shared capabilities for AI evaluation, observability and governance, helping teams assess quality, understand failures and build dependable products.
We are looking for a hands-on Senior Data Scientist to build, evaluate and improve these applications. You will work closely with product teams and education-domain colleagues to translate user needs into practical AI solutions, improve their behaviour and establish whether they deliver meaningful benefits in real settings.
This is a senior individual-contributor role with substantial hands-on delivery. You will own selected workstreams, contribute reusable methods and tools, and provide technical guidance and mentoring to colleagues.
What you will be working on
Work with product managers, engineers, designers and domain experts to understand user needs, identify suitable AI approaches, and define measurable outcomes and quality expectations
Build and iterate on AI prototypes and workflows, using machine learning, large language models, retrieval and tool use where appropriate. Assess trade-offs across quality, cost, latency and practical implementation
Improve AI behaviour through prompt development, structured experimentation and error analysis. Identify whether failures are best addressed through data, prompts, retrieval, model choice, workflow design or human review
Design evaluations that reflect how products are used. Develop representative datasets, quality rubrics and test cases with domain experts, including challenging scenarios and important failure modes
Combine human evaluation with automated methods, checking that automated scores align with human judgement and reveal meaningful differences between approaches
Work with engineers to build reusable evaluation tools, versioned datasets and regression checks, so teams can detect changes in quality as models, prompts and product features evolve
Use product data, user feedback and targeted experiments to assess usefulness and outcomes. Distinguish improvements in model performance from improvements in the experience and work of users
Translate findings into clear recommendations on product priorities, release readiness and further improvements. Communicate limitations, risks and trade-offs to technical and non-technical stakeholders
Apply appropriate data-protection and responsible-AI practices, working with…
