Description

  • Design and ship multi-tenant commerce services including checkout, subscriptions, payments orchestration, invoicing, and tax hooks.
  • Define core commerce models (subscriptions, payments, reconciliation, tax) and the services and contracts around them.
  • Integrate payment service providers and local payment methods (UPI, wallets, BNPL, cards/3DS) with resilient webhooks and idempotent APIs.
  • Implement an append-only double-entry ledger and apply event sourcing/CQRS where it improves scale and correctness.
  • Define event contracts, data policies, and consistency guarantees to ensure each transaction is correct by design and traceable.
  • Write production-grade code with deep test coverage and OpenTelemetry instrumentation.
  • Operate services on GKE with CI/CD, autoscaling, SLIs/SLOs, and take on-call ownership for production systems.
  • Collaborate closely with product and design teams and mentor junior engineers to drive deliverables and quality.

Requirements

  • 4–6 years of software development experience.
  • Proficiency with Go and backend technologies including ConnectRPC and Buf.
  • 1+ years building with protobuf/GRPC/ConnectRPC.
  • Experience with MongoDB/Firestore, Redis, and event-driven systems (Kafka, Pub/Sub).
  • Hands-on experience with GCP (GKE), Pub/Sub, and OpenTelemetry.
  • Strong distributed systems fundamentals: idempotency, retries, ordering, concurrency, and consistency.
  • Deep testing discipline covering unit, integration, contract, and performance testing.
  • Familiarity with secrets/KMS and PCI basics.
  • Solid UI development experience with Vue.js and TanStack Query and ability to build responsive, accessible, performant UIs.
  • Schema design for scale and backward compatibility, plus excellent debugging and problem-solving skills.

Benefits

  • Remote work flexibility (remote as well as Dallas headquarters) and a global, distributed team.
  • Strong company culture focused on creativity, collaboration, and healthy work–life balance.
  • Inclusive hiring practices and reasonable accommodations for individuals with disabilities.
  • Opportunity to work at massive scale (3B+ API hits and 2B+ message events monthly, 80+ TB across databases).
  • Work on a global commerce platform aiming to power $1T+ in annual transactions and serve hundreds of thousands of customers.
