About Anyscale:

Proud to be backed by Andreessen Horowitz, NEA, and Addition with $250+ million raised to date.

What you'll do

• Own a major technical area of Ray Core end to end, defining the roadmap, identifying the most important technical problems, and driving execution through production.
• Lead large, technically complex projects spanning multiple engineers, teams, and/or organizations.
• Set technical direction and make architectural decisions for distributed computing infrastructure used by demanding production workloads.
• Design, build, and evolve core distributed-systems primitives rather than simply integrating existing platforms or frameworks.
• Work on problems involving areas such as distributed execution, scheduling, resource management, fault tolerance, concurrency, networking, storage, or system performance.
• Stay hands-on with implementation and debugging in a systems-oriented codebase, while raising the technical bar for the engineers around you.
• Help shape the longer-term architecture and evolution of Ray Core as our workloads and scale continue to grow.

What we're looking for

• 6+ years of software engineering experience, with a track record of increasing technical ownership.
• Experience leading substantial projects end to end, including defining the problem, creating a roadmap, making architectural decisions, driving implementation, and owning the outcome in production.
• Experience leading projects that are larger than a single-engineer effort, typically spanning multiple engineers and lasting multiple quarters.
• Deep experience with distributed systems and computer systems.
• Strong systems programming experience in languages such as C++, Rust, Java, or similar lower-level languages.
• Strong understanding of systems concepts such as multithreading/concurrency, distributed coordination, resource management, fault tolerance, performance, or networking.
• Experience building foundational systems such as databases, streaming systems, distributed runtimes, operating systems, schedulers, storage systems, Spark, Kafka, or similar infrastructure is highly relevant.
• A track record of mentoring engineers and raising the technical bar of the teams around you.
• Nice to have: Contributions to open-source infrastructure projects.
