Job description

Role Purpose

The Full Stack Software Developer designs, builds and ships production-grade applications for our clients – across the front end, the back end, and the cloud they run on. This role sits close to the work: you will translate business requirements into working software, own features end to end, and use our AI-assisted engineering workbench as part of everyday delivery, not as an experiment.

What You'll Own

1. End-to-End Feature Delivery

• Design, develop and deploy full-stack applications using modern frameworks and cloud-native architectures.
• Take ownership of features or modules from requirement through to production release and post-deploy support.
• Translate business and technical requirements into robust, maintainable, scalable solutions.

2. Engineering Quality & Craft

• Apply best practices in code quality, automated testing, security and performance.
• Participate in code review, uphold architectural standards, and keep technical debt visible and managed.
• Produce clear technical and architectural documentation.

3. AI-Assisted Delivery

• Use SimplifyNext's AI workbench across the lifecycle – story refinement, code generation, test generation, review support and documentation.
• Work within our guardrails: human gates, drift checks, coverage contracts and CI-first verification.

4. Cloud, CI/CD & DevSecOps

• Collaborate with DevOps on CI/CD pipelines, cloud deployments and release automation.
• Embed security requirements from design – secure coding, access controls, vulnerability management.

5. Collaboration & Mentoring

• Work alongside architects, business analysts, designers and client stakeholders in one delivery team, not siloed handoffs.
• Review code and mentor junior developers; recommend improvements to tools, frameworks and approaches.

What You'll Bring

Must-Have

• 3+ years of hands-on experience in full-stack software development, delivering to production.
• Strong front-end experience with modern frameworks (e.g. React, TypeScript, modern JavaScript).
• Solid back-end development experience (e.g. Node.js, Java/Kotlin, Python, .NET).
• Experience designing and consuming APIs, and working with relational and/or NoSQL databases.
• Working knowledge of at least one cloud platform (AWS, Azure or GCP).
• Experience with CI/CD pipelines, version control and modern development workflows.
• Strong communication skills and the ability to work in cross-functional, client-facing teams.
• Degree or Diploma in Computer Science, Engineering or a related discipline.

Good-to-Have

• Containerisation and orchestration experience (Docker, Kubernetes).
• Hands-on use of AI coding assistants or agentic development workflows in a professional setting.
• Experience delivering into the Singapore Public Sector or large regulated enterprises.
• Familiarity with observability and telemetry tooling.
• Interest in growing towards a technical lead or architect track.

This role is not a fit if:

• You want to specialise narrowly on one layer of the stack and stay there.
• You see testing, documentation and code review as someone else’s job.
• You would rather build prototypes than support what you ship in production.
• You are uncomfortable working directly with clients and business stakeholders.
• You see AI-assisted engineering as a threat rather than part of the toolkit.
