About the role
We’re building a top-tier engineering team to reimagine how labor is managed at scale.
Ideal candidates:
- Are hands-on engineers who thrive in ambiguous, high-impact environments
- Care deeply about system design, scalability, and elegant architecture, and are not afraid to reinvent the future
- Want to work closely with product, design, and AI researchers to bring novel experiences to life
- Prioritize outcomes over output and love solving real business problems
Responsibilities
- Develop, and scale resilient backend services using TypeScript, NestJS, and GraphQL with subgraph federation patterns, underpinning real-time API performance requirements at enterprise scale.
- Implement AI-native, event-sourced architectures that blend graph data models with relational database foundations.
- Design data modeling strategies and robust PostgreSQL schemas, tailored for high-concurrency, atomic operations while maintaining performance and correctness.
- Champion best practices in code quality, testing strategies, and data engineering
Your background
- 4+ years in backend engineering with a strong grasp of production-grade systems.
- Proficient in TypeScript and NestJS (or equivalent Node.js frameworks), with extensive experience designing GraphQL subgraphs and federated APIs.
- Deep expertise in PostgreSQL, including schema design, query optimization, concurrency control, and managing migrations in high-scale systems.
- Bonus: hands-on experience with conflict resolution strategies in collaborative systems graph processing, feature stores, or real-time coordination systems.
