Staff Software Engineer - Data Platform

We're looking for a Staff Software Engineer to be a core technical contributor on our real-time event processing platform. You'll design and build event-driven services, drive engineering quality, and mentor junior engineers — all while working with limited supervision on complex problems. This is the first truly senior individual contributor level, and we expect you to bring strong technical judgment, ownership, and a bias for quality. 

What you will do:

• Design and build event processing services and pipelines on AWS serverless (Lambda, Kinesis, EventBridge, Step Functions). 

• Write production-quality Golang and/or Python code with comprehensive testing and observability. 

• Own services end-to-end: development, deployment, monitoring, incident response, and SLA adherence. 

• Make sound architectural decisions for somewhat complex problems, exercising discretion and judgment. 

• Drive code quality through thorough code reviews, testing standards, and documentation. 

• Investigate and resolve production incidents independently; contribute to postmortem analysis. 

• Design and implement CI/CD improvements for better developer experience and deployment safety. 

• Mentor Analyst-level engineers through pairing, design guidance, and constructive review feedback. 

• Propose and implement improvements to platform resilience, performance, or cost. 

• Participate in on-call rotations independently with full accountability.
