Solutions Engineer

TL;DR

We help large enterprises cut energy costs and carbon emissions by steering their energy use in sync with market prices and renewable generation. The value is clear, and demand is growing. We are looking for a Solutions Engineer to help speed up integrations.

You will work closely with both customers and our product team to implement and scale our platform. This role sits at the intersection of backend development, integration, and customer delivery. If you like solving practical problems with code and systems thinking, and seeing your work have a direct impact, we'd love to meet you.

Why Companion.energy?

Solve real problems

Our customers rely on us to connect, control and optimise their energy systems, from heating and cooling, over batteries, to solar panels. You'll work directly with the systems that power their factories and warehouses.

Bridge software and the physical world

We're not just building dashboards. We're writing code that helps real assets react to real market signals, every minute of the day. You'll work on the critical link between our platform and the digital and physical systems of our customers.

Join early, help shape the future

We're still a small team. You'll have a say in how we integrate with customers, how we deploy solutions, and how we evolve the architecture to scale.

A mission that matters

Helping companies adapt to a volatile energy landscape isn't just smart business, it's key to accelerating the energy transition.

What you'll do

• Lead technical onboarding for new industrial customers
• Build and deploy integrations between energy systems, assets and our cloud platform
• Collaborate with backend engineers on core architecture and tooling
• Work with customers to understand constraints and translate them into actionable setups
• Troubleshoot and solve edge-case issues in real-world environments
• Help standardise and scale how we deliver high-quality, repeatable integrations

What we're looking for

• Experience writing scripts or backend code (Python)
• Familiarity with APIs, data pipelines, or systems integration work
• Strong troubleshooting and debugging mindset, especially with real-world systems
• Comfortable working hands-on with our customers' engineering teams
• A practical communicator: you explain technical topics clearly, both internally and externally
• Curious and proactive: you ask the right questions, and figure things out

How we hire

• A short intro call to get to know each other
• A practical case or scenario to understand how you think
• Follow-up conversations with team members and founders

We keep things simple and move fast.
