What you will be working on

About TradeNet

TradeNet is Singapore's National Single Window for trade permit processing. It processes over 9 million permit applications annually across import, export and transshipment. As one of Singapore's key trade systems, TradeNet is being brought in-house to strengthen technology ownership and long-term sustainability.

How we build

Dsignated as critical IT infrastructure, we favor simple, durable technology choices over the latest trends. We prioritize systems that are easy to reason about, operate, and maintain for the long term.

We operate with high autonomy. Engineers are expected to think deeply, exercise sound judgement, and take ownership of technical decisions. You own the code from technical design through to production. We practice and value honest feedback, practical decision-making and real impact.

In the role of Senior/Staff Software Engineer within Platform Engineering, you will direct the technical evolution of the underlying platform that underpins all TradeNet product development, placing a strong emphasis on resilience, security compliance, observability, and developer efficiency at scale.

Operating horizontally across product squads, Platform Engineering delivers core infrastructure, standardized tooling, reliable runtime environments, automated deployment guardrails, and deep operational visibility. This framework empowers product teams to deliver software safely, efficiently, and autonomously without facing routine operational friction.

You will collaborate closely with software engineering squads, security, and architecture teams to establish scalable platform practices, automate infrastructure delivery, enhance production resilience, and ensure high system availability.

Teams here use AI-assisted development workflows daily. You need to be comfortable with that and will drive adoption of these practices across TechOps.

What you'll do

Platform Architecture & Resilience

Architect Multi-Cluster Foundations: Design and evolve a resilient, hub-and-spoke multi-cluster Kubernetes infrastructure on AWS, optimizing for zero downtime, multi-region failover, cost efficiency, and performance.

Advance Zero-Trust Infrastructure: Drive the implementation of Istio Ambient mesh, mTLS, and fine-grained authorization policies across complex network topologies.

Observability & Reliability: Establish comprehensive observability, logging, metrics, and alerting to proactively identify and resolve performance bottlenecks, participating in incident response and blameless post-mortems to strengthen MTTR.

Platform Engineering & Developer Experience

Build Golden Paths: Enable product teams by transforming tenant onboarding and infrastructure management into self-service workflows backed by modular, reusable Terraform/OpenTofu code and clear reference architectures.

GitOps at Scale: Standardize declarative continuous delivery using ArgoCD/ Rollouts (ApplicationSets, multi-cluster synchronization) and modern CI/CD pipelines.

Governed self-service: Squads deploy independently within approved guardrails, owning the release metrics (deployment frequency, lead time, change failure rate, MTTR).

Security, Compliance & Governance

Fortify Security Posture: Lead platform security assessments and penetration test remediations; integrate SIEM logging, privileged access management (PAM), and tight egress controls.

Drive Technical Governance: Author Architecture Decision Records (ADRs) and technical RFCs, leading cross-functional architecture reviews to set technical standards across TradeNet while ensuring compliance readiness (audit evidence, CSA/CSG/IM8 accreditation).

Technical Leadership & Mentorship

Build Engineering Capability: Mentor senior and mid-level engineers across teams, elevating technical craft, fostering shared ownership of critical systems, and cultivating a strong engineering culture.

Set and enforce TradeNet-wide engineering standards across code quality, AI-assisted development workflows, and testing.

What we are looking for

Scale & Expertise: At least 8+ years (Senior) or 12+ years (Staff) of software/platform engineering experience, with 3+
