Job Description
You will be responsible for building and evolving the core backend systems and shared infrastructure that power our platform. A significant portion of backend logic is shared across services and this role will help define maintain and scale that foundation.
You will own and improve internal schema and code generation tooling that ensures consistency and correctness across services. You will work on and extend our custom job scheduler improving reliability observability and execution guarantees for distributed workloads. You will contribute to safely execute large-scale concurrent and distributed operations.
You will play a key role in defining and maintaining API standards across teams ensuring performance backward compatibility and clear evolution strategies. You will collaborate closely with Product and various Engineering teams to design systems that are reliable scalable and maintainable over time.
About the role:The Core Systems team is responsible for the foundational backend infrastructure that powers Weights & Biases within CoreWeave. Much of the platform’s critical logic is shared across services and this role sits at the center of that foundation. You will work on the systems that other engineers build upon — from execution frameworks and schedulers to schema tooling and API standards.
This is a high-leverage role focused on durability scalability and long-term maintainability. The systems you design and evolve will directly impact reliability developer velocity and the ability of the platform to scale with growing workloads. You’ll collaborate across teams to ensure that shared backend abstractions remain clean performant and consistent as we continue to expand our adoption of technologies like GraphQL and gRPC.
If you enjoy owning deep technical infrastructure shaping engineering standards and building systems that other engineers depend on every day this role offers meaningful scope and impact.
Who You Are:- 5+ years of backend engineering experience building and operating production systems.
- Proven experience designing and maintaining distributed systems at scale.
- Hands-on experience designing and evolving APIs (REST GraphQL and/or gRPC).
- Strong proficiency in Go Python or a comparable backend systems language.
- Experience implementing concurrency and parallelism patterns in production systems.
- Demonstrated ownership of shared infrastructure internal platforms or developer tooling used by multiple teams.
- Experience diagnosing and optimizing system performance including CPU memory I/O and network bottlenecks.
- Familiarity with schema management code generation tools or interface definition systems (e.g. protobuf OpenAPI GraphQL schemas).
- Experience building or operating custom job schedulers workflow engines or execution frameworks.
- Experience defining cross-team API standards and governance models.
- Background in high-scale data or ML infrastructure systems.
- Experience improving reliability through observability metrics and SLO-driven development practices.
