System Development Engineer, Pyxis ADC

This is an excellent opportunity to join Amazon's world-class technical team at HQ2 in Arlington, VA, working with some of the best and brightest engineers while developing your skills and furthering your career within one of the most innovative technology companies anywhere. Amazon Software Builder Experience (ASBX) Pyxis ADC provides the foundational services that every Amazon builder depends on to develop, deploy, and operate software from continuous deployment orchestration to testing infrastructure and configuration management. Our team owns and operates critical ASBX services across Amazon's most secure and isolated environments, including Apollo (deployment), Pipelines (continuous delivery), Test on Demand/Hydra (integration testing), AppConfig (feature management), Multi-Region (resource replication), Builder MCP, and AIM (AI agent infrastructure). We ensure these services maintain parity, reliability, and security across all partitions. A successful Engineer joining the team will do much more than write code and triage problems. They will operate services at scale in air-gapped environments where standard commercial tooling doesn't exist, drive cross-partition deployment parity, and build the automation that keeps Amazon's most sensitive workloads shipping safely. They will dive deep into complex distributed systems issues and work diligently to improve the builder experience. The ideal candidate will: - Be great fun to work with. Our company credo is "Work hard. Have fun. Make history." The right candidate will love what they do and instinctively know how to make work fun. - Have strong Linux & Networking Fundamentals. The ideal candidate will have deep experience working with Linux, preferably in large-scale, distributed environments. You understand networking technology, how services communicate across isolated boundaries, and regularly take part in deep-dive troubleshooting and technical post-mortem discussions to identify root causes of complex issues. - Love to code. Whether it's building deployment automation, creating AI-powered operational tooling, or solving complex cross-partition orchestration problems, the ideal candidate will love using technology to solve problems. You have a solid understanding of software development methodology and CI/CD practices. - Think Big. The ideal candidate will build and deploy solutions that enable thousands of Amazon builders to ship software reliably across multiple isolated regions. You will strive to improve and streamline processes to allow delivery at massive scale. This position requires that the candidate selected must currently possess and maintain an active TS/SCI security clearance. The position further requires that, after start, the selected candidate obtain and maintain an active TS/SCI security clearance with polygraph or commensurate clearance for each government agency for which they perform AWS work. A day in the life You start the morning reviewing deployment health across isolated regions, checking alarms and on-call handoffs. Mid-morning, you're deep in a code review for a cross-partition automation fix, then jump into a design discussion on how to bring a new ASBX service capability to air-gapped environments. After lunch, you troubleshoot a deployment pipeline issue, tracing it from orchestration logs to a configuration mismatch, and ship the fix before end of day. Between the technical depth and the autonomy to own problems end-to-end, no two days look the same.
