About Us
Electron is a fast-growing tech company in the energy flexibility space. We’re working to transform how electricity grids work, as the need for electricity doubles and the increase in renewables continues to add pressure to the grid. We’re looking to bring more passionate people into our team to help us do this! In just a few years, we’ve gone from pilot projects in the UK to over 50% market share with full platform deployments, becoming the leading platform for flexibility markets. As the UK is the most advanced country in the flexibility space, this also makes us the leading flexibility market platform globally too. More recently, we’ve expanded into the US through acquisition, marking the next phase of our global growth and enabling us to work with some innovative utilities in the US. At our core, Electron helps electricity networks use the grid more intelligently. As more electric vehicles, batteries, and renewables connect to the grid, traditional infrastructure struggles to keep up. Instead of just relying on expensive physical upgrades, Electron enables a smarter, faster solution. Our products allow utilities and grid operators to tap into flexible energy - working with resources like batteries, EVs, and other distributed energy resources - exactly when and where they’re needed. In simple terms, we help find value on the grid in real time, reducing costs, improving grid reliability, and accelerating the transition to clean energy. In the UK, we work with over half of the country’s Distribution System Operators and have already enabled 7 GWh of flexibility - helping networks connect more customers, avoid unnecessary infrastructure upgrades, and keep electricity flowing reliably. This, in turn, can reduce consumer bills in the long run too!
Electron is a mission-driven tech company with real-world impact. We’re building the digital foundations of the modern electricity grid in an ever changing energy world - making it cheaper, cleaner, and more resilient - and we’re looking for people who want to shape the future of energy with us.
The Role
The Software Engineer (Mid-Level) is responsible for contributing to the development and improvement of Electron’s energy trading platform and innovation projects. This role focuses on building reliable, well-tested software while continuing to deepen technical expertise. Working closely with senior engineers, the role supports delivery across the full development lifecycle and plays an active part in agile, collaborative teams.
How We Work
The engineering team gets together twice a week in our London office. We work in agile teams, delivering value efficiently from a prioritised backlog. We release to production early and often. Automated testing and CI/CD pipelines enable teams to own the full delivery lifecycle. Collaboration, pairing and shared ownership are core to how we build software.
What We Offer
- Salary: £50,000 - £70,000 depending on experience, with the ability to participate in the success of the company through our share option scheme
- Flexible working: Hybrid model with 2 days/week in our London office
- Benefits: Pension scheme, 25 days holiday plus bank holidays
- Growth: Direct mentorship from senior engineers, ownership of features, and opportunities to expand your technical skills across our full stack
- Impact: Work on technology that’s directly enabling the clean energy transition and helping achieve net-zero
- Culture: Collaborative, learning-focused team where knowledge sharing, pair programming, and continuous improvement are core values
Responsibilities
- Collaboration & Ways of Working: Work as part of a tight-knit, agile engineering team delivering value iteratively. Pair program where appropriate to learn from others, share knowledge and improve quality. Collaborate closely with product, delivery and other technical team members. Actively contribute to continuous improvement of team practices and processes.
- Technology & Platform Development: Contribute to the development and maintenance of features across Electron’s energy flexibility trading platform. Work primarily with Angular on the frontend and ASP.NET Core on the backend. Build and consume Web APIs and event-driven services. Work with relational databases (PostgreSQL) and gain exposure to NoSQL data stores.
- Technical Growth & Best Practice: Write clean, maintainable, and well-tested code. Contribute to automated testing and CI/CD pipelines. Learn and apply engineering best practices with guidance from senior team members. Take part in code reviews, pair programming, and technical discussions.
Who We are Looking For
We’re seeking an engineer who is curious, adaptable, and eager to grow. You don’t need to have worked with our exact tech stack - we value relevant experience and the ability to learn over perfect matches.
Essential:
- Experience building web applications with modern frontend frameworks (React, Vue, Svelte, or similar - Angular experience is a bonus but not required)
- Backend development experience with a strongly typed language (C#, Java, TypeScript, Go, Kotlin, or similar)
- Understanding of RESTful APIs and web application architecture
- Experience with relational databases
- A collaborative mindset and willingness to pair program and share knowledge
- Enthusiasm for learning new technologies and approaches
Desirable:
- Exposure to event-driven architectures
- Experience with automated testing and CI/CD pipelines
- Experience with cloud-based infrastructure
Most importantly, we’re looking for someone who is genuinely excited about contributing to the clean energy transition and working in a team that values learning, collaboration, and continuous improvement.
