About the role

Staff Engineer role focused on building a global commerce platform to power $1T+ in annual transactions. IC with org-level influence responsible for domain modelling, architecture, reliability, and developer enablement across subscriptions, payments, catalog, pricing, inventory, fulfillment, reconciliation, and tax.

Responsibilities

  • Architect and ship multi-tenant, planet-scale services (checkout, subscriptions, payments orchestration, invoicing, tax hooks) with clear domain boundaries (DDD) and hard SLOs
  • Be the custodian of API & schema design: own protobuf/ConnectRPC conventions, versioning policy, deprecation playbooks, and Buf breaking-change checks—so our contracts stand the test of time
  • Guarantee resilience & availability of core payment paths: timeouts, retries with jitter, circuit breakers, idempotency keys, outbox/Saga patterns, hedged requests, and graceful degradation
  • Ensure complete auditability: append-only double-entry ledger, immutable event streams, trace-linked entities (OTel trace/span IDs), tamper-evident trails, and reconciliations that tie out to the cent
  • Own error boundaries end-to-end: enumerate failure domains (PSP, network, data, concurrency, quota, browser, device); design uniform error contracts; implement compensations/backfills and automated replay
  • Keep track of every deployed thing: services, workers, triggers, cron, subscriptions—own the service catalog and scorecards (owners, SLOs, runbooks, PDBs, HPA/VPA, budgets, quotas, timeouts)
  • Configuration & limits stewardship: enforce sane defaults across GKE, Pub/Sub, Redis, Firestore/Mongo, ClickHouse—connection pools, ack deadlines, batch sizes, TTLs, memory/FD limits, and GCP quotas
  • Observability as a product: pervasive OpenTelemetry, RED/USE metrics, exemplars, trace sampling, SLO dashboards, and alerting that wakes humans only for user-impacting issues
  • Production excellence: canary/blue-green rollouts, automated rollbacks, chaos drills, DR playbooks (RPO/RTO), multi-region failover strategies, and incident command on rotation
  • Security & compliance by design: PCI scope minimization, tokenization/vaulting, secrets/KMS hygiene, data retention/archival, and privacy controls—embed checks in CI/CD
  • Developer acceleration: pave golden paths (service templates, ADR/RFC process, linting/formatting, contract tests, ephemeral envs, load/perf harnesses) to make the right thing the easy thing

Qualifications

  • 10+ years building and operating backend systems (at least 5+ years in Go)
  • 2–3+ years acting as a Staff/Principal‑level IC or Tech Lead for critical paths
  • Deep proficiency with protobuf + ConnectRPC/gRPC and API lifecycle management (versioning, compatibility, contract testing, Buf)
  • Distributed systems fundamentals: idempotency, exactly‑once‑ish via dedupe/outbox, ordering, consensus basics, backpressure, concurrency control
  • Event‑driven architectures on GCP (Pub/Sub), plus Redis for fast paths; strong schema design in MongoDB/Firestore and analytics/reporting patterns on ClickHouse
  • Kubernetes/GKE operations at scale: autoscaling (HPA/VPA), PDBs, resource limits/requests, multi‑region topologies, CI/CD, canary/blue‑green
  • Reliability engineering: SLIs/SLOs, error budgets, capacity & load testing, incident management, DR/BCP
  • Security & compliance: secrets/KMS best practices, PCI basics (scope reduction, key rotation), and data governance (retention/archival)
  • Testing discipline: unit, integration, contract, property‑based, performance; test data management and deterministic environments
  • Fronted collaboration: solid understanding of Vue.js + TanStack Query to shape clean API surfaces and performance budgets across the boundary
  • Exceptional technical writing & communication: design docs, ADRs/RFCs, postmortems, and stakeholder updates
