About this role
Arcline Systems processes over $40M per month through Stripe and a custom internal ledger, and the volume is growing. We're looking for a Senior Backend Engineer to own and evolve the payments integration layer — the infrastructure that makes sure money moves correctly, every time.
You'll work on a small, collaborative team (6 backend, 2 frontend, 1 DevOps) that writes design docs, reviews each other's RFCs, and takes ownership seriously without taking itself too seriously. We're fully remote, but we fly everyone to Portland once a quarter to eat too much food and whiteboard things that probably could've been Slack messages.
What You'll Do
Own the payments integration layer end-to-end: Stripe, internal ledger, webhook processing, reconciliation
Design and build reliable, idempotent transaction flows that handle edge cases gracefully
Write and maintain infrastructure-as-code (Terraform) for payment services running on AWS (Lambda, SQS, RDS/Postgres)
Participate in on-call rotation (~1 page/month — it's not bad, but payments can break at 2 AM)
Contribute to our RFC and design doc culture — we think through problems on paper before writing code
Help the team stay SOC 2 compliant without losing our minds
What We're Looking For
5+ years building backend systems in Python (Django, FastAPI, or Flask — we use Django but we're flexible)
Real experience with payment systems or fintech infrastructure — not "I used Stripe once," but understanding idempotency, retry logic, debit/credit flows, webhook reconciliation
Strong AWS chops: Lambda, SQS, RDS, and ideally some Terraform experience
Comfort working on-call for payment-critical systems
Low ego, high communication. We write a lot of design docs and we talk through trade-offs as a team
Nice to Have
Experience with event-driven architecture (Kafka or Kinesis)
Familiarity with SOC 2 compliance in a production environment
Experience mentoring other engineers
Benefits
$165K–$195K base + equity
Fully remote with paid quarterly onsites in Portland
401(k) with match
Unlimited PTO — and we actually track it so people use it
