About the role

Senior role building Pangolin, Antithesis's bespoke streaming analytical database, focusing on on-disk storage formats, query optimization, and scalable, tree-native processing for terabytes of data daily. Close collaboration with internal customers and infrastructure to deliver high-performance, correct systems.

Responsibilities

  • Build and evolve Pangolin, our bespoke analytical database — a tree-native, streaming system handling terabytes of customer data daily.
  • Work closely with internal customers — including the notebook/UI team — to define priorities, shape the roadmap, and deliver features that make data exploration faster and more fluid.
  • Collaborate with the broader Infrastructure team on deployment, reliability, and scale.
  • Write clean, well-reasoned design docs and contribute to the long-term technical direction of the system.

Qualifications

  • Strong proficiency in Rust; safe, performant, idiomatic code is second nature to you.
  • Deep systems programming fundamentals — you can reason about memory, concurrency, and performance from first principles.
  • Strong CS fundamentals in data structures and algorithms, with a habit of solving hard problems from the ground up.
  • Strong backend engineering background; you've worked on or alongside database systems and understand what makes them tick — the more depth, the better.
  • Product-minded: comfortable talking to internal customers, translating fuzzy requirements into concrete priorities, and owning delivery.
