Software Engineer – Battery Energy Storage Systems (BESS) | Edinburgh | £45,000 – £60,000
Build the software powering the energy transition.
At StorTera, we’re redefining how energy is stored, controlled, and optimised. As a leading innovator in commercial-scale battery energy storage, we develop advanced software and hardware solutions that stabilise the grid, unlock renewable energy, and help businesses decarbonise at scale.
We’re now looking for a Software Engineer to help build and scale our energy management platform — the digital brain behind our next-generation flow battery technology and BESS deployments.
If you’re excited by real-world systems, high-impact software, and clean energy, this is your chance to make your code count.
The Software Engineer Role:
You’ll play a key role in designing, developing, and scaling the software that controls how energy is stored, dispatched, and optimised across commercial battery systems.
Working at the intersection of edge devices, cloud platforms, IoT, and electrical engineering, you’ll turn high-frequency sensor data into actionable intelligence — helping customers save money, reduce carbon, and improve grid resilience.
This is hands-on, mission-critical engineering with real-world impact.
Key Responsibilities of the Software Engineer:
Build scalable backend services using cloud-native, microservices architectures to process real-time data from BESS, EV chargers, solar, wind, and IoT sensors
Develop optimisation algorithms for peak shaving, demand response, automated load shedding, and (where appropriate) AI-driven forecasting and anomaly detection
Connect edge to cloud, designing robust APIs and drivers using protocols such as OCPP, Modbus, and CAN, with secure, low-latency data pipelines
Collaborate on data visualisation, supporting intuitive dashboards and reports that drive operational and commercial decisions
Ensure security & reliability, implementing high-availability controls and industry-standard cybersecurity for grid-connected assets
What We’re Looking For:
Degree in Software Engineering, Electrical Engineering, or similar
Experience with C++, Rust (edge / performance-critical systems) and/or Python, Go, or Java (cloud services)
Hands-on experience with Docker, Kubernetes, and event-driven architectures
Experience working with time-series and relational databases (e.g. InfluxDB, TimescaleDB, PostgreSQL)
Cloud deployment experience on AWS, Azure, or GCP
A systems-thinking mindset — comfortable writing software that safely interacts with physical hardware and high-voltage systems
Exposure to machine learning for forecasting or optimisation is a plus
Strong communication skills and the ability to thrive in a fast-moving, collaborative environment
A genuine commitment to high engineering standards, sustainability, and societal impact
Early-career engineers welcome: We’re happy to consider candidates with less than 3 years’ experience. If you have strong fundamentals and the right mindset, we’ll invest in your growth with structured training and mentoring.
