The Staff Backend Engineer will own the design and delivery of robust, scalable backend systems — from API architecture and microservice design to containerized deployments and a focus on edge run-time environments. You'll work to improve reliability, security, and developer velocity, and help shape how we build and scale our platform.

Responsibilities

• Architect and implement production-grade backend APIs in Python: async patterns, clean service boundaries, data modeling, migrations, and observability.
• Design and evolve a microservice architecture: service decomposition, inter-service communication (REST/gRPC/event-driven), and fault-tolerant system patterns.
• Own containerization and orchestration: Docker-based workflows, container lifecycle management, and deployment orchestration across environments.
• Drive edge runtime strategy: design and deliver services optimized for low-latency, edge-first execution environments.
• Contribute to performance-critical components in Rust or Go where throughput, latency, or resource constraints demand it.
• Lead architecture and execution: break down ambiguous problems, define standards, review code, and mentor engineers.
• Collaborate with infrastructure owners on deployment patterns, secrets management, and AWS service integrations — without owning that layer directly.

Required Skills

• Deep Python backend experience: FastAPI or similar, async patterns, relational databases (Postgres), and migrations.
• Strong microservice design experience: service decomposition, API contracts, and inter-system communication.
• Docker and container-based development and deployment workflows.
• Familiarity with Rust or Go for systems-level or performance-critical work.
• Strong communicator who can drive alignment across engineering teams.

Personal Values

• Bias to action, self-motivated and entrepreneurial spirit
• Attention to detail, effective time management, and pride in work
• Dependable, trustworthy, empathetic, and full of integrity
• Strong collaborative communication skills
