Software Development Engineer III

The Data-Informed Engineer (Economic Discipline): You care about the why behind the code. You understand that latency and cloud spend are engineering disciplines, and you optimize your infrastructure so that our cost-per-order remains predictable as we scale. The Proactive Collaborator (Security and Governance): You thrive in a cross-functional environment (Eng, Data, DevOps, Security). You take ownership of the Golden Path, ensuring 100% of your repositories are gated and that zero critical vulnerabilities ever reach our production environment.

Responsibilities:

• AI-Native Velocity: Lead the 70% AI-assisted PR mandate by mastering Cursor, Copilot, and Claude to accelerate delivery of Node.js (NestJS) and Golang microservices while keeping human intelligence focused on high-level system design and architecture decisions.
• Unbreakable Backend Architecture: Architect high-throughput, event-driven microservices using Kafka and Redis, embedding resilience patterns like circuit breakers, health checks, and fallback mechanisms to handle massive traffic spikes without manual intervention.
• Data and Performance Ownership: Own the unit economics of the data layer, optimize MySQL and MongoDB queries, design efficient schemas, and ensure sub-second p99 latencies with predictable infrastructure costs on GCP.
• End-to-End Golden Path Ownership: Drive features from design docs to Kubernetes deployment, ensuring high reliability through strong engineering practices and maintaining low change failure rates and minimal Sev-1 incidents.
• API and Service Design Excellence: Build clean, versioned, and backward-compatible APIs and modular microservices with a strong focus on maintainability, scalability, and clear service contracts.
• Cloud-Native Operations and Observability: Design and operate services on Kubernetes with robust logging, monitoring, and alerting; proactively debug production issues and ensure high availability.
• Scalability and Cost Efficiency: Continuously optimize system throughput, fault tolerance, and infrastructure utilization to support high growth while maintaining strict control over cloud costs.
• Technical Leadership and Collaboration: Lead design decisions, write clear RFCs, mentor engineers, and collaborate closely with Product, Frontend, Data, and DevOps teams to drive high-quality outcomes.
• Core Engineering Excellence: Apply strong fundamentals in distributed systems, concurrency, and data structures, combined with sharp problem-solving, debugging, and communication skills.

Requirements:

• Languages and Frameworks: Node.js (NestJS / Express), Golang.
• Data and Messaging: MySQL, MongoDB, Redis, Kafka, Aerospike, ElasticSearch.
• Infrastructure: Kubernetes, GCP / AWS, Docker.
• Observability: Prometheus, Grafana, OpenTelemetry.
• AI Productivity: Cursor, Claude, GitHub Copilot
