About the Role
We are looking for a Full Stack Software Developer to design, engineer, and maintain specialised software testing toolkits that support large-scale, mission-critical operational systems.
These toolkits play a key role in validating system functionality, performance, and reliability. You will work end-to-end across frontend, backend, system integration, automation, and deployment, collaborating closely with engineers, testers, and operational users to ensure the tools meet technical, regulatory, and real-world operational requirements.
This role is ideal for developers who enjoy building systems that directly support national-scale, high-availability environments.
What You Will Work On:
Full Stack Development
- Design and develop full stack testing toolkits and simulators, covering both frontend interfaces and backend logic.
- Build intuitive user interfaces for configuration, execution, monitoring, and reporting using modern web technologies.
- Develop backend services, APIs, and automation components to support simulation, test execution, and data generation.
System Integration & Automation
- Integrate with enterprise systems, gateways, and third-party APIs as required.
- Implement automation frameworks and CI/CD pipelines to streamline validation, testing, and deployment processes.
- Monitor performance, investigate issues, and apply optimisation strategies.
Collaboration & Delivery
- Work with system engineers and QA teams to translate operational and technical requirements into robust test scenarios.
- Support system integration, acceptance testing, and commissioning activities.
- Prepare and maintain documentation including architecture, design specs, test plans, and user guides.
Quality, Security & Best Practices
- Ensure the testing toolkits are scalable, maintainable, and aligned with software engineering best practices.
- Adhere to relevant regulatory, compliance, and cybersecurity requirements across the development lifecycle.
- Stay current with emerging technologies and propose improvements to processes and tooling.
What We're Looking For
Must-Haves
- Singapore Citizen or Permanent Resident.
- Minimum 2 years of full stack software development experience ideally within mission-critical, enterprise, or high-availability systems.
- Strong frontend proficiency in HTML5, CSS3, JavaScript/TypeScript and frameworks such as React, Angular, or Vue.
- Strong backend development experience in Python, Java, Node.js, or similar languages.
- Experience working with RESTful APIs, microservices architectures, and SQL/NoSQL databases.
- Comfortable with system simulation, data modelling, and automated test data generation.
- Familiar with version control (Git), automated testing, CI/CD pipelines, code reviews, and agile development practices.
- Strong problem-solving skills with attention to detail and a structured approach.
- Good communication and documentation skills.
Nice to Have
- Experience with cloud environments (AWS, Azure) or containerisation tools (Docker, Kubernetes).
- Experience in large-scale operational systems, command-and-control platforms, or real-time data systems.
- Understanding of cybersecurity considerations in critical systems.
- Ability to travel for integration work or stakeholder engagements.
