[Overview]

We are looking for a hands-on Senior Software Engineer to join a team building and evolving a business-critical digital platform within the public sector. This is a role for an engineer who enjoys solving complex engineering problems, working with rich domain logic, and building systems where reliability, correctness, and maintainability are essential.

You will work on systems that support important public-sector operations and real-world business processes. The work involves understanding complex workflows, designing clean and maintainable solutions, strengthening core application capabilities, and helping the team build software that is reliable, testable, observable, and safe to evolve.

Success in this role requires more than strong coding ability. We are looking for someone who can reason through business processes, make sound technical trade-offs, contribute to technical direction, and help uplift engineering quality across the team.

[What you will be working on]

Digital transformation within the public sector is at the heart of what GovTech does. We harness technology to solve meaningful and underserved problems across multiple domains.

In this role, you will help design, build, and evolve a complex digital platform with high data integrity requirements, transaction-heavy workflows, and significant operational impact. As a Senior Software Engineer, you will be responsible for implementing core application logic and services, while contributing to modern engineering practices and sustainable system design.

Your responsibilities will include:

• Designing and implementing backend services, APIs, and application logic for complex business workflows
• Understanding business processes, data relationships, and operational rules, and translating them into maintainable software designs
• Designing clean domain models, service boundaries, and data models that support correctness, extensibility, and long-term maintainability
• Building validations, state transitions, orchestration flows, and exception handling for transaction-heavy processes
• Working closely with QA engineers, business analysts, and fellow developers to ensure the system is testable, observable, and production-ready
• Writing high-quality, maintainable code with strong automated test coverage
• Participating in technical design discussions, code reviews, defect analysis, and release readiness activities
• Supporting system evolution, data reconciliation, and integration between existing and new platform capabilities where required
• Documenting key technical decisions, business-rule assumptions, and implementation trade-offs clearly
• Contributing to engineering standards, development practices, and delivery discipline across the team
• Providing technical guidance to peers and helping uplift engineering quality through collaboration, mentoring, and knowledge sharing

[What we are looking for]

Technical Requirements

• Strong hands-on experience in Java
• Strong experience building backend services using frameworks such as Spring Boot
• Strong experience with TDD and test automation tools such as JUnit, JMeter, or equivalent
• Experience with REST APIs, backend workflow implementation, and enterprise integration patterns
• Strong experience with relational databases such as PostgreSQL, Oracle, or equivalent
• Experience with modern frontend development using NodeJS and TypeScript / JavaScript is a plus
• Experience working on large-scale, business-critical, or domain-heavy enterprise systems is a plus
• Experience in the AWS ecosystem, such as EC2, RDS, and EKS, is a plus

Additional technical expectations

• Strong software engineering fundamentals in backend and service development
• Strong understanding of data modelling, transactional integrity, and stateful workflow design
• Experience writing unit, integration, and service-level automated tests
• Experience with CI/CD, source control workflows, and release-safe engineering practices
• Ability to troubleshoot across application, data, and integration layers
• Familiarity with observability, production support, and operational debugging
• Good judgment in balancing code quality, delivery pace, operational constraints, and long-term maintainability
• Ability to work with ambiguity, learn complex domains, and contribute constructively to technical decisions
