- Collaborate with Product/Design/Engineering to ship production-ready functionality
- Write clean, maintainable code with strong testing practices
- Improve reliability and scalability (latency, throughput, resilience, cost)
- Participate in code reviews and help uphold strong engineering standards
Core Requirements
- 5+ years of professional software engineering experience
- Strong Golang experience and solid service-oriented architecture skills
- Production experience with cloud infrastructure (ideally AWS)
- Hands-on with modern backend tooling such as Docker, Kubernetes, gRPC, Kafka (or equivalent)

- Strong observability habits (metrics/logging/tracing, incident response)
- Prior experience in highly regulated, fintech, or high-compliance environments
- Exposure to crypto / Web3 (not required)
