About ST Engineering

ST Engineering

is a global technology, defence, and engineering group with offices across Asia, Europe, the Middle East, and the U.S., serving customers in more than 100 countries. The Group uses technology and innovation to solve real-world problems and improve lives through its diverse portfolio of businesses across the aerospace, smart city, defence, and public security segments. Headquartered in Singapore, ST Engineering ranks among the largest companies listed on the Singapore Exchange.

Our history spans more than 50 years, and our strategy is underpinned by our core values – Integrity, Value Creation, Courage, Commitment and Compassion. These 5 core values guide every aspect of our business and are embedded in our ST Engineering culture – from the people we hire, to working with each other, to our partners and customers.

About our Line of Business – Mission Software & Services

Our Mission Software & Services business provides leading-edge mission critical command, control, and communications (C3) systems with secured IT infrastructure and managed services. We support our client’s innovation journey through design thinking, analytics, and AI-enabled decision support with our full suite of cloud computing solutions. We provide intelligent, actionable insights and sustainable solutions to our valued partners in diverse industries including defence, government, and commercial sectors.

Together, We Can Make A Significant Impact

You will lead technical delivery across the full engineering lifecycle from discovery and architecture through to production operations, while coaching client engineering teams to build lasting capability. This is a consultancy role: you set the technical bar, de-risk decisions through prototyping and spikes, and are as energised by enabling others as by building great software yourself.

Be Part of Our Success

• Lead technical discovery and architecture design for greenfield and legacy modernisation — microservices, event-driven, API-first, strangler patterns.
• Champion quality engineering: comprehensive test strategy, code review, pair programming, TDD, refactoring, and technical debt management.
• Build production-quality applications with strong test coverage; deploy on modern cloud platforms with CI/CD and infrastructure as code.
• Define API contracts and integration patterns; run spike solutions and POCs to de-risk architecture decisions before full build.
• Proactively surface technical risks, communicate trade-offs clearly, and keep delivery momentum across engineering and business stakeholders.
• Establish monitoring and observability frameworks; faciliti any technical retrospectives to continuously improve engineering practice.
• Enable client engineers through pairing, tailored coaching, and feedback — build end-to-end engineering capability, not dependency.
• Facilitate technical workshops — architecture reviews, mob programming, discovery sessions — across distributed and co-located teams.

Qualities We Value

• Experience: 5+ years of full-stack engineering across the full lifecycle — architecture, development, testing, deployment, and production ops — on both greenfield and legacy modernization.
• Coaching: Proven experience enabling engineers through pairing, workshops, or mentorship across distributed and co-located teams.
• Technical: Language and framework agnostic strong in cloud platforms, CI/CD, security best practices (OWASP), AI-augmented tooling; consultancy experience presenting trade-offs to non-technical stakeholders.
• Mindset: Quality-first; thrives on ambiguity, energised by enabling others same as building; pragmatic;
• Familiarity with GovTech platforms (SHIP-HATS, SG Tech Stack, GCC) or prior work with Singapore Government agencies.

Our Commitment That Goes Beyond the Norm

• An environment where you will be working on cutting-edge technologies and architecture.
• Safe space where diverse perspectives are valued, and everyone’s unique contributions are celebrated.
• Meaningful work and projects that make a difference in people’s lives.
• A fun, passionate and collaborative workplace.
• Competitive remuneration and comprehensive benefits.
