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.
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.
You will be surrounded by some of the best talent in the industry, who will want to learn from you, too.
