Lead Backend Engineer - Low Carbon Tech (LCT)

Additional details

• Octopus Energy started with a bold idea: to build Britain’s first truly digital energy supplier.
• By combining world-class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we made it happen and in 2025, we became Britain’s largest energy supplier.
• Now, we’re scaling our services business, making it easy to switch to heat pumps, solar and EVs, and launching smart tariffs for Low Carbon Tech.
• With this, we’re also taking the learnings, products and experiences that customers love here and rolling them out worldwide.
• OE Tech is the engineering and product organisation inside Octopus Energy.
• Here you’ll have real ownership, variety, and the chance to shape products that make a tangible difference in people’s lives: lowering bills, enabling greener living, and delivering experiences customers genuinely love.
• You’ll work side by side with teams across services, marketing, operations, and data, and see the impact of your work in the real world, fast.
• We are installing EV Chargers, Solar, Batteries and Heat Pumps into homes to drive the energy transition at pace.
• As customer demand grows, our goal is to ensure scaling up never means slowing down or compromising on a world-class customer journey for low carbon tech.
• To make that happen, we are building a new, dedicated engineering and product team to completely re-imagine this process - making it fast, transparent, and predictable for our customers from day one.
