Staff Software Engineer, Backend (Affiliate Platform)

The Company

Your Role

• As a Staff Software Engineer, Backend (Affiliate Platform), you will design, build, and operate backend services and APIs that power our affiliate platform—including tracking & attribution, commission calculation/settlement, partner management, and anti-fraud controls. You will own critical services end-to-end (design, implementation, testing, deployment, observability, and reliability) and contribute to adjacent backend platform capabilities as needed (e.g., identity/account, commerce/order/OTD integrations, and analytics instrumentation) across our robotics consumer journey.
• Key Responsibilities:
• Build and evolve backend services for affiliate domains: event tracking & attribution, commission rules and settlement, partner onboarding/management, and anti-fraud/abuse controls.
• Design and maintain clear, versioned REST/gRPC APIs and partner integration patterns (e.g., webhooks/callbacks), with strong backward compatibility and well-defined contracts.
• Implement high-throughput event ingestion and durable workflows using datastores + caching + messaging/streaming, ensuring correctness, scalability, and debuggability.
• Ensure settlement-grade correctness for financially sensitive flows: idempotency, reconciliation, audit trails, safe retries, and clear state machines.
• Improve performance and reliability: profiling, query optimization, caching strategies, load/capacity testing, latency/throughput tuning, and cost-aware scaling.
• Operate services in production with strong observability and reliability practices (logs/metrics/traces, SLOs/alerts, incident response) and safe delivery (CI/CD, canary/blue-green releases, zero-downtime migrations).
