Senior Full Stack Software Engineer
About The Position
ExTrac is seeking a Senior Software Engineer based in the Washington, DC area to work across backend services and the infrastructure they run on.

The role includes building and maintaining AWS infrastructure using infrastructure-as-code, deploying and troubleshooting containerised workloads, improving CI/CD pipelines, developing microservices and APIs, and contributing to system architecture. The engineer will instrument and secure services and infrastructure, participate in incident response and post-incident reviews, and implement controls supporting US compliance frameworks such as FedRAMP and CMMC. The role includes out-of-hours incident support through an on-call rota. The engineer will work closely with the Lead DevOps Engineer on US priorities, partner with the UK backend team across time zones, and collaborate with analysts and product managers. This is a remote role for someone located on the East Coast, with occasional travel to the DC area for collaborative working sessions. The role requires regular overlap with UK working hours, such as US Eastern mornings.
