Mission

We're building the brain of green energy.

PowereX operates a Virtual Power Plant — a distributed system that controls, in real time, hundreds of batteries, solar installations, and flexible energy resources as a single intelligent whole. Our platform trades on European energy markets, stabilizes power grids, and replaces fossil-fuel backup with clean flexibility.

These aren't CRUD endpoints. These are decisions made in milliseconds that change where your electricity comes from.

You won't be closing tickets — you'll be building the brain of the VPP.

• Hardware & market integrations — connecting batteries, inverters, and SCADA systems; sending commands to OKTE, SEPS, and intraday exchanges

• Real-time control commands — sub-second pipelines where latency = money or penalties

• Control & trading orchestration — connecting control algorithms (dispatch, flexibility activation, SOC management) with trading and market infrastructure; ensuring the right signal reaches the right place at the right time

• Market data & forecasting — time-series at massive scale, ML models for prices and consumption

• Infrastructure — event-driven architecture (Kafka), cloud-native AWS, IaC via Terraform

• Backend: Java (Spring Boot / Micronaut), Python, Bash

• Cloud: AWS Lambda, ECS/Fargate, MSK (Kafka), Glue, S3, Batch

• Data: TimescaleDB, R, Keras / PyTorch / GBMs

• DevOps: Terraform, Terragrunt, Ansible, Docker, GitHub Actions

• Observability: Grafana, Prometheus, ELK, OpenSearch

• Java or Python at senior/mid level (ideally both)

• SQL + time-series — you know what a hypertable is and why it matters

• Systems thinking — you understand distributed systems, failure modes, idempotency

• Fluent Slovak + English — you'll communicate with clients and an international team

• Work authorization in the EU

• Experience with Terraform/Terragrunt

• AWS certifications or deep knowledge of the ecosystem

• Background in energy, IoT, algorithmic trading, or control systems

• Freedom — results over micromanagement; you choose your tools

• Impact — your code reduces CO₂ and keeps the grid frequency stable

• Bratislava office or full remote (EU)

• Flat team of ~30 people — no politics, no unnecessary bureaucracy

• Flexible working hours
