Software Engineer

Job Summary

SGX is hiring product-minded engineers to take initiatives from ambiguous problem to running production system. You'll partner with stakeholders to shape what gets built, prototype rapidly to validate direction, and harden the result into systems we operate with confidence. This is a generalist role for engineers who like build and can orchestrate AI agents across the SDLC.

We operate in a regulated capital-markets environment, so the bar for quality, security, and operational rigour is high.

What You Will Do

Own initiatives end-to-end: clarify and extend requirements with stakeholders, propose what to build, and see it through release and operation

Move from idea to working prototype in days, then evolve prototypes into production systems that handle edge cases, scale, and adversarial conditions

Apply AI agentically across the full SDLC, and contribute back to our internal agentic ecosystem: the workflows and tools the rest of the team relies on

Define release readiness: test strategy, rollout plans, observability, runbooks, and treat security, maintainability, and documentation as first-class concerns

Design and integrate distributed systems where they matter: messaging (e.g. Kafka), orchestration (e.g. Kubernetes), performance-sensitive protocols (e.g. Aeron, gRPC, Protobuf), etc

What We Are Looking For

5+ years of professional software engineering, with a clear track record of taking work from idea to production and owning it there

AI-native ways of working: real experience orchestrating coding agents and composing agentic workflows across specification, build, test, deploy, and operation

Fluency in at least two modern languages (e.g. Java, Kotlin, TypeScript, Python, Rust) and willingness to learn whatever a problem demands

Solid foundations in distributed systems, APIs, and messaging, with judgement about when sophistication is warranted

Production mindset across testing, observability, security, and CI/CD

Product instinct: comfortable shaping scope rather than waiting for a complete spec

Comfort in complex, regulated environments

Nice to Have

Familiarity with the FIX protocol or capital-markets domain

Experience building internal developer tools, agent frameworks, or platform tooling

Front-end experience to support end-to-end prototyping
