About the Role
We are looking for an ambitious AI & Software Engineer to join our team and play a key role in building the technology infrastructure that enables our AI-powered battery energy storage systems (BESS) to connect, communicate and interact intelligently with the electricity grid.
This is a highly hands-on role at the intersection of AI, software engineering, energy technology, IoT and grid infrastructure. You will be responsible for developing the software platforms, APIs, control systems and data infrastructure required to monitor, optimise and coordinate our batteries in real time.
The ideal candidate will be excited by the opportunity to build technology from the ground up and work on a product that sits at the heart of the transition towards a smarter, more flexible energy system.
Key Responsibilities
Grid & Battery Infrastructure
- Design and develop software infrastructure connecting our battery systems to the electricity grid.
- Develop communication layers between batteries, inverters, meters, energy management systems and cloud platforms.
- Build systems capable of securely receiving and transmitting real-time energy and grid data.
- Develop interfaces and APIs for communication with external energy companies, aggregators, network operators and energy markets.
- Help develop systems capable of controlling battery charging, discharging and power output in response to grid conditions.
AI & Optimisation
- Develop AI/ML-driven systems to optimise battery charging and discharging.
- Build algorithms that analyse electricity prices, grid demand, battery state and other market data to determine optimal battery behaviour.
- Develop forecasting models for energy demand, electricity prices and renewable generation.
- Continuously improve battery performance through data-driven optimisation.
- Explore opportunities to use AI for predictive maintenance, fault detection and battery degradation modelling.
Software Engineering
- Design and build scalable backend infrastructure for our battery fleet.
- Develop APIs and microservices to connect hardware, software and external platforms.
- Build real-time data pipelines for battery and grid telemetry.
- Develop dashboards and monitoring tools to track battery performance and system health.
- Implement automated testing, monitoring, logging and deployment processes.
- Work with cloud infrastructure to ensure systems are reliable, scalable and secure.
IoT & Real-Time Systems
- Work with IoT technologies to connect physical battery assets to our software platform.
- Develop secure device communication and remote-control functionality.
- Process high-frequency telemetry from distributed battery systems.
- Design systems capable of operating reliably in real-time environments.
- Troubleshoot connectivity, communication and hardware/software integration issues.
Security & Reliability
- Implement strong cybersecurity practices across connected battery infrastructure.
- Ensure communications between batteries, cloud infrastructure and third parties are secure.
- Design systems with appropriate redundancy, monitoring and fail-safe mechanisms.
- Ensure software meets relevant energy-sector, cybersecurity and grid-connection requirements.
Required Experience & Skills
- Strong software engineering background, ideally with experience in Python, Java, C++, JavaScript/TypeScript or similar languages.
- Experience developing APIs, backend systems and cloud-based applications.
- Strong understanding of databases, data pipelines and distributed systems.
- Experience working with REST APIs, MQTT, WebSockets or other communication protocols.
- Experience with cloud platforms such as AWS, Azure or Google Cloud.
- Strong understanding of software architecture and system design.
- Experience working with real-time data or IoT systems.
- Strong problem-solving and analytical skills.
- Ability to work independently and take ownership of technical projects.
Desirable Experience
Experience in any of the following would be highly advantageous:
- Battery Energy Storage Systems (BESS)
- Energy Management Systems (EMS)
- Electricity grids and grid balancing
- Renewable energy
- Energy trading or flexibility markets
- Demand response
- Virtual Power Plants (VPPs)
- IoT and connected hardware
- Industrial control systems
- Machine learning / AI
- Time-series data
- SCADA systems
- Modbus, CAN bus or similar industrial communication protocols
- Energy APIs or electricity market data
- Cybersecurity for connected infrastructure
- Kubernetes, Docker and CI/CD
What You'll Build
You will have the opportunity to help build a platform that can ultimately allow hundreds or thousands of batteries to operate as an intelligent, coordinated energy network.
The technology you develop could enable our batteries to:
- Automatically charge when electricity is cheap or renewable energy is abundant.
- Discharge when grid demand is high.
- Respond to grid signals in real time.
- Participate in energy and flexibility markets.
- Optimise revenue across multiple energy markets.
- Predict and prevent battery faults.
- Learn from historical battery and grid behaviour.
- Operate as part of a Virtual Power Plant (VPP).
The Ideal Candidate
We are looking for someone who is more than just a software developer. You should be fascinated by the challenge of connecting physical energy infrastructure to sophisticated software and AI.
You will ideally be someone who:
- Enjoys building products from the ground up.
- Can move comfortably between software, AI, APIs and hardware.
- Is comfortable working in an early-stage or fast-moving environment.
- Takes ownership rather than waiting for detailed instructions.
- Can turn complex technical problems into practical solutions.
- Is excited about the future of energy, batteries and AI.
- Wants to have a significant impact on the architecture and direction of the company.
Why Join Us?
This is an opportunity to join at an early stage and help build the core technology behind an AI-powered energy platform.
You will have significant influence over the technical architecture and will work across AI, software, batteries, IoT and the electricity grid.
If you are an engineer who wants to work on a genuinely challenging problem with the potential to transform how batteries interact with the energy system, we would love to hear from you.
This list is not exhaustive, and amendments and additions may be required in line with future policy changes.
Pay: £50,000.00-£70,000.00 per year
Work Location: In person
