  • Contribute to CI/CD pipeline hygiene, infrastructure-as-code standards via Terraform, and GitLab pipeline optimization
  • Participate in technical interviews and candidate evaluations
  • May lead small, less critical, or temporary team structures and projects

Basic Qualifications
  • 7+ years of relevant engineering experience and a Bachelor's degree, or equivalent additional experience in lieu of a degree
  • Must meet federal suitability requirements and pass a background investigation as a condition of employment
  • Expert-level proficiency in at least one of: frontend engineering (Angular, JavaScript, HTML/CSS) or backend engineering (Python, Java, PostgreSQL, Elasticsearch)
  • Strong working knowledge of containerized microservices and AWS services (ECS, RDS, S3, Lambda, CloudWatch)
  • Experience building and consuming versioned RESTful APIs with published OpenAPI specifications
  • Hands-on experience with CI/CD pipelines in GitLab and version control via Git
  • Working knowledge of WCAG 2.1 AA accessibility standards and their application to frontend or backend development
  • Strong written and verbal communication skills, able to translate technical decisions for non-technical audiences including federal agency stakeholders

Preferred Qualifications
  • Prior experience with federal agency digital services or government contracting environments
  • Experience with infrastructure-as-code using Terraform
  • Familiarity with event-driven architectures using AWS SNS/SQS and Lambda/Step Functions
  • Experience with consumer-driven contract testing using Pact or API contract governance across microservices
  • Exposure to SAFe or scaled Agile delivery frameworks including PI planning and ART coordination
  • Familiarity with third-party integrations such as Pay.gov, login.gov, or identity/authentication platforms
  • Experience mentoring engineers in a cross-functional federal delivery environment
