About us
Ingrid was born out of a simple belief: the energy transition must move faster and work smarter. We're pioneers at the forefront of the global energy transition — pushing boundaries, turning bold ideas into reality, and solving the problems that matter most.

The INtelligent GRID of tomorrow needs to absorb and release more power. We develop, build and operate high-performance batteries — the lungs of modern energy infrastructure — enabling a more flexible and resilient energy supply across Europe. With 500 MW already deployed across the Nordics and rapid expansion into continental Europe, we manage, optimise and trade both our own assets and those of third parties through our sophisticated tech platform, making every battery — and the entire grid — stronger.

About the role

Software and smart solutions are at the core of how we tackle the toughest bottlenecks in the power system. The platform our Ingrid Technology team builds makes real-time trading decisions, balances the grid and optimises assets – running at scale, around the clock, against live energy markets where timing and reliability decide the outcome.

What you'll do

• Go deep in one of our key domains. Optimisation & Trade, Delivery & Steering, or the Partner Experience Platform — and grow with it as we scale.

• Design, build and maintain production-grade backend services. In Python (FastAPI, Pydantic, SQLModel/SQLAlchemy, Alembic migrations), with RESTful and event-driven APIs, deployed as containerised micro services in the cloud.

• Build real-time, event-driven systems. Our services react in real time to continuously trading markets, a constant flow of surrounding data, and the physical steering of our assets — you'll design Pub/Sub event flows that stay predictable when messages arrive late, twice or not at all.

• Design and evolve application databases. PostgreSQL, Redis, BigQuery and S3 — schema design, migrations and query optimisation.

• Own the path from commit to production. CI/CD, containerisation, monitoring and observability — with security and auth built in from the start, not as an afterthought.

Your background

• Deep backend experience in Python. Production services with modern tooling – FastAPI or equivalent, type-safe patterns – and you know your way around relational databases.

• Experience with event-driven or distributed systems. You've worked with message queues or event streams – Pub/Sub, Kafka or similar – and know the trade-offs they bring.

• At home in the cloud, ideally GCP. Or another major provider with a curiosity to learn – you don't just deploy services, you keep them monitored, observable and healthy in production.

• Experience with the energy sector is meritable, but not required. We'll get you up to speed on the domain.

• AI-native and genuinely keen on modern AI tooling, using it to sharpen your own workflow and helping colleagues get the most out of theirs.
