Role: Backend & Infrastructure Engineer

We are hiring a Backend & Infrastructure Engineer to build and scale the platform that powers our energy products. You will own the infrastructure and data systems that connect hundreds of battery installations, ensuring reliability, performance, and scalability as we grow.

We are building Co-Power to power Europe's industry. We believe in a future of true energy abundance, where clean electricity is ultra-affordable, resilient, and a competitive advantage for European manufacturers.

We install large-scale batteries at industrial sites and connect them into an intelligent network that manages electricity in real time, turning factories into energy hubs and making intermittent renewables reliable, dispatchable, low-cost power available around the clock.

Our mission is bold – and we're looking for people who don't just want to rethink energy, but to build the energy company of the future.

What You Will Do

• Own platform reliability and infrastructure scaling as we grow from pilot sites to hundreds of connected battery systems.
• Contribute to data platform architecture – help shape how we ingest, store, and serve time-series data from battery systems and EMS integrations.
• Optimize database performance for high-throughput telemetry data at scale.
• Design monitoring and alerting logic for system health, timeseries data, and model performance in production.
• Build and improve CI/CD pipelines and deployment automation for backend services on AWS.
• Work closely with our data science team to bring models into production with a strong focus on robustness and real-world performance.

What We're Looking For

• 3–5+ years of experience in backend engineering, infrastructure, or platform roles.
• Production AWS experience (ECS, Lambda, EventBridge, RDS).
• Strong PostgreSQL skills – query optimization, indexing, performance tuning.
• Python backend development (FastAPI, SQLAlchemy preferred).
• Infrastructure-as-code (Terraform, CDK, or CloudFormation).
• Comfort with SQL for data exploration and pipeline development.

Bonus if you are experienced with:

• Time-series databases (TimescaleDB, InfluxDB, or similar)
• MLOps practices – model versioning, experiment tracking, CI/CD for ML pipelines
• Energy sector or IoT experience

Benefits

• A competitive salary, potentially alongside equity in Co-Power.
• Top-notch equipment. You choose what you need.
• A dog-friendly office at Goetheplatz, Munich, with all the usual shenanigans.
• While we allow for plenty of flexibility, we ask for an office-first commitment: when you're not traveling, most of your time will be in the office. In an early-stage company, people learn faster, connect better, and accomplish more when they spend meaningful time together.
