Senior Platform Software Engineer, Braze

• If you are driven to solve exhilarating challenges and have a bias toward action in the face of change, you will be empowered to make a real impact here, with a sharp and passionate team at your back
• 5+ years of experience in software engineering, platform engineering, or SRE, with a strong record of writing production code (not only operating systems)
• Hands-on experience running stateful, distributed systems in production at scale
• Strong working knowledge of Kubernetes and infrastructure-as-code (Terraform, Pulumi) and comfort building on top of them
• Proficiency in at least one general-purpose language such as Go, Python, or Ruby. We care more about design judgment than language choice
• A systems mindset: you think about interfaces, failure modes, and edge cases, and you debug methodically when things break
• A strong problem-solving mindset and a track record of working with other teams to untangle complex engineering problems
• Clear written and verbal communication, and comfort collaborating across time zones
• A bias toward fixing what's broken instead of working around it
• We know that sometimes different circumstances can lead talented people to hesitate to apply for a role unless they meet 100% of the criteria. If this sounds familiar, we encourage you to apply, as we’d love to meet you

• Own and evolve Braze's observability platform, including metrics collection, long-term storage, alerting, and dashboards, so teams can detect and diagnose issues early
• Lead capacity planning, upgrades, and migrations for large, stateful systems with minimal customer impact
• Partner with engineering teams across Braze to improve how they use these systems, from data modeling and access patterns to query performance and monitoring
• Investigate complex production issues across the stack and turn what you learn into durable fixes and better tooling
• Contribute to the team's on-call rotation and help improve runbooks and write tooling that would help incident response
• Document your designs and decisions clearly for a global team
