About the Senior Full Stack Engineer role
The Senior Full Stack Engineer will provide technical leadership for a flagship platform and its supporting products across modern and legacy codebases. The role involves maintaining application stability, delivering fixes and security updates, supporting infrastructure, troubleshooting issues, and monitoring system performance. The engineer will lead platform migrations and legacy system retirement, make sound architecture decisions, establish development and release standards, and mentor less senior engineers. The role also requires close coordination with engineering, product, stakeholders, and vendors while maintaining technical documentation and ensuring the portfolio remains secure, reliable, and maintainable.
Key responsibilities:
- Anchor the portfolio technically: Own the technical health of the flagship platform and the supporting products across multiple languages and codebases, from legacy to modern stacks
- Maintain and support: Deliver bug fixes, security patches, infrastructure upkeep, L2 and L3 support, and monitoring across the portfolio
- Lead migrations: Complete the platform v2 migration and retire the legacy codebase, and decide and coordinate adaptations for planned work such as system migrations to the target platform
- Set standards and mentor: Define and enforce code review, testing, and release practices, and guide the Consultant engineer through review and pairing
- Keep it maintainable: Keep runbooks, architecture notes, and handover material current so the products stay maintainable and transferable
- Coordinate across teams: Work with client team engineers, product staff, and stakeholders to align on priorities, risks, and delivery
Requiremets:
- Experience: Minimum 7 years of hands-on full stack software engineering, including a senior or lead role
- Languages and frameworks: Strong proficiency with a modern JavaScript or TypeScript framework (React), backend APIs and services, and relational databases (PostgreSQL). Proven ability to navigate, debug, and change code across several languages, codebases, and legacy systems
- Architecture: Make sound design and architecture decisions, and reason about tradeoffs in a maintenance and migration context
- Cloud and infrastructure: Solid knowledge of cloud-hosted applications, containerized deployments (Docker), and CI/CD pipelines
- Observability and troubleshooting: Analyze logs and metrics using AWS tools such as ECS and CloudWatch, and OpenTelemetry for tracing, metrics, and logs
- Version control and code review: Strong practice with Git and quality gates, and experience setting review standards
- Software lifecycle: Deep understanding of the software development lifecycle and Agile delivery on product-centric teams
- Security-aware: Attention to secure coding practices and awareness of government security and compliance requirements
- Coordination: Experience coordinating cross-team work and guiding less senior engineers
- Government domain: Familiarity with government or public-sector delivery contexts
Preferred Qualifications:
- Self-directed: A driven, resourceful engineer who can pick up unfamiliar codebases quickly and lead without close direction
- Pragmatic: Balances speed and quality, and makes sensible tradeoffs in a maintenance context
- Comfortable with ambiguity: Navigates shifting priorities as products transition, sunset, or transfer
- Collaborative: Builds good working relationships with stakeholders, teammates, and vendors, and influences across teams
- Ownership: Takes responsibility for the stability, quality, and technical direction of the products in their care
