Execution

Senior Distributed Systems Engineer

Own the checkpointing layer: the part of the product that decides whether a failure costs a retry or a restart.

Remote — Europe, MENAFull-time$165,000 – $205,000

What you'll do

  • Design and evolve the durable execution model, including checkpoint ordering and idempotency key derivation
  • Reduce checkpoint write cost without weakening the guarantee
  • Build the failure injection harness we test resumption against
  • Carry a share of the on-call rotation for the execution plane

What we're looking for

  • Five or more years building systems where correctness under partial failure was the hard part
  • Practical experience with exactly-once effects, not just exactly-once delivery claims
  • Comfort reasoning about ordering, idempotency, and clock skew without hand-waving
  • A written record — design docs, postmortems, or commits — we can read
