About Job
Summary

Phage.Energy is a deep-tech Virtual Power Plant (VPP) platform.

We unify distributed energy assets, operational constraints, and market processes into a single real-time control system — from telemetry ingestion to dispatch and execution confirmation.

This is a backend-heavy product operating in real time, where reliability, determinism, and control logic are critical.

Responsibilities

Build the VPP control core: assets, clusters/groups, operating modes, and constraint handling.

Process telemetry and maintain a consistent real-time platform state (availability, limits, readiness).

Implement dispatch logic: preparing, sending, tracking, and validating control commands; handling retries and failures.

Aggregate platform-level indicators (power, availability, readiness) for dashboards and optimization logic.

Deliver production-grade behavior: stability, observability, fault tolerance, and predictable execution.

Requirements
What we Expect

Must have:

  • 5+ years of backend development experience
  • Strong Node.js + TypeScript
  • Experience with NestJS
  • Event-driven architecture experience
  • Solid understanding of reliability patterns: idempotency, state consistency, retries, failure modes
  • PostgreSQL experience

Nice to have:

  • AWS experience (Lambda, API Gateway, DynamoDB, Kinesis, IoT Core, Timestream)
  • Real-time systems (WebSocket, streaming pipelines)
  • Time-series data experience
  • Experience in energy, infrastructure, IoT, or other real-world control systems
