📋 Description

• Own the telemetry data flow from AWS IoT Core and Kafka into TimescaleDB, including legacy GCP Pub/Sub, with accountability for throughput, correctness, latency, cost, stability, and scalability • Evolve the GraphQL contract and design secure, low-latency GraphQL and REST APIs for web and mobile clients • Reduce infrastructure and observability cost per device, cut latency, and eliminate throughput bottlenecks as the fleet grows • Implement Kafka partitioning, consumer groups, batched writes, backpressure, and hot-path isolation • Use Grafana to identify slow queries, monitor the pipeline, and maintain proactive alerts • Safely evolve the live system through staged reversible changes, parallel runs, shadow validation, and rollback • Review frontend and mobile work and trace issues across Vue charts, Timescale queries, and Kafka consumers • Stabilize and cost-optimize the telemetry path while maintaining latency and throughput targets • Extend APIs for new product features without regressing latency or breaking clients • Act as a senior voice in incident response and reduce support load • Collaborate with firmware, service, and commercial colleagues to turn telemetry into reliable tooling

🎯 Requirements

• 5–10 years building and operating production backend systems, including meaningful experience with high-throughput streaming or time-series data • Deep practical knowledge of Kafka partitioning, consumer groups, rebalancing, ordering, idempotency, and schema evolution • Strong SQL and time-series database skills, including TimescaleDB, ClickHouse, InfluxDB, or equivalent • Experience designing secure, low-latency GraphQL and REST APIs for web and mobile clients • Experience migrating a live system without downtime using parallel writes, shadow validation, staged cutover, and rollback • Fluency in TypeScript and Node.js; experience with NestJS services • Production AWS experience, including ECS, IoT Core, networking, and Terraform/IaC • Ability to become productive in Go quickly; prior Go experience is a plus, not a requirement • Ability to write clear technical documentation • First-hand experience managing live systems during production incidents • Ability to explain systems precisely and concisely to technical and non-technical stakeholders • Ability to set technical direction, conduct rigorous reviews, and improve engineering practices • Ability to simplify systems and work through legacy technical debt
