About the role

Key responsibilities & impact

Own and improve the telemetry data pipeline from AWS IoT Core and Kafka into TimescaleDB, including legacy GCP Pub/Sub
Ensure pipeline throughput, correctness, latency, cost efficiency, stability, and scalability
Evolve GraphQL contracts and design secure, low-latency GraphQL and REST APIs for web and mobile clients
Keep the backend-for-frontend layer maintainable as the schema and product grow
Reduce infrastructure and observability cost per device, latency, and throughput bottlenecks
Improve Kafka partitioning, consumer groups, batched writes, backpressure, and hot-path isolation
Use Grafana to identify slow queries, monitor pipelines, and maintain proactive alerts
Safely deploy reversible changes using parallel runs, shadow validation, staged cutovers, and rollback
Review frontend and mobile work and trace bugs across Vue, TimescaleDB, and Kafka
Stabilize and cost-optimize telemetry as the device fleet scales
Extend APIs for new product features without latency regressions or client breakage
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
Build and maintain Enernet, Ampd Energy’s cloud platform for fleet monitoring, alarms, scheduling, reporting, and technician mobile applications

Requirements

What you’ll need

5–10 years building and operating production backend systems
Meaningful experience with high-throughput streaming or time-series data
Deep practical knowledge of Kafka partitioning, consumer groups, rebalancing, ordering, and idempotency
Experience with schema evolution, strong SQL, and time-series databases such as TimescaleDB, ClickHouse, or InfluxDB
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; NestJS experience relevant to the services stack
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 quality
Ability to simplify systems and work through legacy technical debt
