The role

You will join the backend team to build distributed systems that power annotation workflows. You will work across product, ML, and ops teams to build resilient, observable, and secure systems.

What you will do

• Help design and build distributed systems that support high-throughput data review and annotation pipelines
• Build systems that prioritize performance and reliability under real-world load
• Apply strong security and privacy practices, including fine-grained access control, secure data handling, and auditable workflows
• Translate cross-functional requirements into clean APIs and backend abstractions
• Collaborate with product, ML, and operations to streamline efficiency and feedback loops
• Participate in design reviews and contribute to architectural decisions on your team's systems
• Write clean, well-tested, maintainable code and give thoughtful code review feedback to peers

• Comfort with operational practices — you write code with observability, alerting, and failure recovery in mind
• Working knowledge of security principles, including least privilege and secure transport/storage
• Ability to take reasonably well-scoped requirements and turn them into solid design and interfaces, asking good questions when things are ambiguous
• A collaborative mindset — you give and take feedback well and enjoy working closely with teammates
