Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Baselayer as an employer.

What you need

  • Shipped product features that touched ingestion to storage to API to customer, end-to-end, in production.
  • Owned a Postgres schema that real money or real decisions depended on, and stayed on top of its evolution.
  • Strong async Python with experience running async services at scale.
  • Deep Postgres expertise: schema design under live load, EXPLAIN ANALYZE as a reflex, zero-downtime migration tooling.
  • FastAPI (or close equivalent): shipped real APIs with auth dependencies, OpenAPI contracts, and structured response models.
  • Built multi-tenant APIs where access control is load-bearing and scoped correctly at the data layer.

Nice to have

  • Entity resolution / record linkage / fuzzy matching at scale.
  • Search infrastructure - full-text, fuzzy, or vector - kept in sync with a Postgres system of record.
  • KYC/KYB/fraud/underwriting data-pipeline experience.
  • Address parsing/normalization at country scale.
  • Webhook delivery infrastructure: retries, signing, idempotency, and ordering guarantees.

What you get

  • Flexible PTO so you can recharge without red tape
  • In-person energy: We're based in SF and meet in the office 4 days a week
  • We pay well and back it with equity. We want you to think and act like an owner
  • We cover 100% of your health, dental, and vision premiums. No surprise deductions from your paycheck
  • 401(k) with company match: We match your contributions so your future self benefits too
  • We contribute to your HSA on applicable plans, so your coverage works as hard as you do

Worth weighing

  • The role involves working with legacy systems and data integration challenges.
  • The position requires a strong focus on performance optimization under real customer load, which may involve complex problem-solving.
  • The company is at an inflection point, which may imply a fast-paced and evolving work environment.
