  • Proven ability to diagnose and resolve software vulnerabilities and complex system bugs.
  • Able to work on-site in Washington, DC.
  • Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:
  • Safety, security, or transportation domain experience.
  • Containerized architectures on ECS.

To apply, submit your resume highlighting REST APIs you built on AWS, services you used (Lambda, API Gateway, Kinesis, ECS), and CI/CD work in GitHub or CodePipeline. Pure application development without API platform or AWS experience will not be considered.
