The environment emphasizes ownership, experimentation, and practical engineering outcomes. Engineers are trusted to move quickly from concept to implementation while contributing to architecture and system design decisions.
This role is well suited for engineers who enjoy solving difficult technical problems, building scalable systems, and working in environments where engineers are expected to take initiative and deliver meaningful technical outcomes.
What You'll Do
Design and develop modern full-stack applications and distributed systems
Build backend services using Python (including frameworks such as FastAPI) and Go
Develop frontend interfaces using React and modern JavaScript frameworks
Deploy and operate applications in containerized and Kubernetes-based environments
Rapidly prototype and validate new platform capabilities
Contribute to architecture and system design discussions
Build scalable APIs and services supporting evolving platform needs
Use modern engineering tooling, including AI-assisted development tools, to accelerate development
Collaborate with engineers and technical leadership to move concepts into production-quality systems
What You Bring
Strong candidates typically bring experience across several of the following areas:
Professional experience building full-stack software systems
Backend development using Python, including frameworks such as FastAPI
Backend systems development using Go
Frontend development using React and modern JavaScript
Experience deploying applications using Docker and Kubernetes
Familiarity with microservices, APIs, and distributed systems
Ability to work independently, solve complex problems, and deliver working software quickly
Comfort operating in environments where engineers take ownership of technical outcomes
Experience using modern development tooling and engineering workflows
Travel
This role includes periodic travel for engineering collaboration sessions, including several extended working sessions during the year. Travel schedules are planned in advance and designed to support focused development and team collaboration.
Clearance
Candidates must be eligible to obtain a U.S. government security clearance.U.S. citizenship is required for clearance eligibility.
