Job description

In this role, you will be directly responsible for:

• 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 & 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 & 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 & Observability: Design and operate services on Kubernetes with robust logging, monitoring, and alerting; proactively debug production issues and ensure high availability.
• Scalability & Cost Efficiency: Continuously optimize system throughput, fault tolerance, and infrastructure utilization to support high growth while maintaining strict control over cloud costs.
• Technical Leadership & 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.

TECH STACK

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