Qualifications

Proven experience in full stack development with a solid understanding of both front-end and back-end technologies. Strong leadership skills with the ability to mentor and guide junior engineers. Experience designing and implementing complex software architectures. Ability to collaborate effectively with cross-functional teams. Passion for clean energy and a deep understanding of the challenges in the renewable sector.

About the job

At Spruce, we are driven by our commitment to revolutionize home energy in the UK, making it accessible and affordable for every household to be powered by clean electricity. Our primary customers are installers, who are leading this critical transition but have historically faced challenges with outdated and inefficient software.

Having launched in early 2024, we have experienced remarkable growth, securing multiple rounds of funding from prestigious venture capital firms, and now proudly support over 500 heat pump installation businesses across the UK.

We are seeking a remarkable Lead Full Stack Engineer to accelerate our progress and broaden our impact as we venture beyond heat pumps.

About Spruce

We tackle one of the most challenging yet essential aspects of the home energy transition: replacing traditional boilers with innovative heat pumps. With nearly 20% of the UK's carbon emissions stemming from home heating, transitioning away from gas and oil boilers is vital for reaching net zero. Heat pumps stand out as the only scalable solution, capable of converting 1kW of electricity into an impressive 4kW of heat ().

However, the installation process remains cumbersome, fragmented, and excessively manual, which inflates costs for homeowners, hampers the growth of installation businesses, and complicates urgent replacements when a boiler fails.

We are addressing this challenge with our comprehensive operating system designed specifically for heat pump installers. This system streamlines operations from initial inquiries through design, installation, compliance, and paperwork. Compared to leading alternatives, Spruce:

  • Reduces the time installers spend on each job by half;
  • Increases sales conversion rates twofold;
  • Enhances quality, profit margins, and customer satisfaction.

And this is just the beginning. With new investments and rising demand, we are expanding into the broader home renewable energy supply chain, supporting manufacturers and merchants alongside installers, and facilitating solar and battery installations in conjunction with heat pumps.

Your Role

As our Lead Full Stack Engineer, you'll blend hands-on technical expertise with team leadership and product strategy. You will continue to write significant portions of code, particularly for critical components, but your influence will grow as you define direction, remove obstacles, and elevate team performance.

You will collaborate closely with engineers, designers, and product leaders to ensure we are constructing the right things, in the right way, and at the right time.

About Spruce-2

Spruce is dedicated to driving the transition to sustainable energy in the UK by providing innovative solutions for heat pump installers. With a focus on efficiency and user experience, we aim to simplify the installation process and support the growth of renewable energy practices across the country.
