About Hometree

Join Hometree Group and be at the forefront of transforming the residential energy landscape. Founded in 2015, Hometree began in the home cover market. Today we’re spearheading the shift to decentralised, digitised home energy systems using heat pumps, solar panels, batteries, EV chargers and smart controls. This approach isn’t just about sustainability; it empowers homeowners to manage energy more efficiently and cost-effectively, setting new standards in energy consumption.

We operate across three dynamic divisions :

Financial Services : Here, you'll contribute to offering flexible financing options that make it feasible for homeowners to embrace renewable energy technologies and make essential upgrades.
Energy Services : Be part of our extensive network of local installation businesses that equip homeowners with the cutting-edge, sustainable energy solutions necessary for reaching net-zero emissions.
Home Services : Help maintain the comfort and functionality of homes with comprehensive coverage plans that protect essential hardware.

At Hometree Group, we are committed to guiding UK homeowners on their journey towards more sustainable energy solutions, and we need passionate individuals to support them at every step. Join us during this exciting time and play a pivotal role in a business that supports sustainable homeownership in alignment with homeowners readiness and needs.

Key Achievements

85m+ capital raised : We’ve raised over £85m to date from leading global investors including Legal & General Capital and specialist energy VCs.

300m+ UK’s first residential renewable securitisation : We have secured a £300m+ facility from Barclays, CPP Investments and partners.

6 acquisitions : We've expanded our operations by acquiring key companies across financing (Hometree Finance, formerly Bewarm), home cover (Your Repair) and energy services (Geowarmth, The Little Green Energy Company, IMS and GreenGen).

100k+ homes covered : We cover over one hundred thousand homes across the UK.

300+ employees : We have over 300 passionate employees transforming the industry across the Group, one home at a time.

The Role

As Senior Full Stack Developer for Hometree Finance, you’ll play a key role in evolving our bespoke loan / lease management platform. You’ll work across our Python / Django back end and Next.js / React / TypeScript front end, delivering scalable, high-performance solutions for partners and consumers. In our fast-growing, hands-on team, you’ll thrive if you’re a self-starter who values quality, speed and collaboration.

Responsibilities

Full-Stack Development : Architect and build scalable web applications, leveraging Python and Django on the back end alongside Next.js and React on the front end.

Clean Code & Performance : Write clean, maintainable code, develop and document robust RESTful APIs, and continuously tune for speed, reliability and scalability.

Cross-Functional Collaboration : Partner with Product, Account Management and Operations to translate business requirements into clear technical specifications—and ship features rapidly.

Troubleshooting & Support : Proactively identify, diagnose and resolve issues across the full stack, and provide ongoing maintenance to keep the platform running smoothly.

Automated Testing & QA : Build and maintain comprehensive test suites—unit, integration and end-to-end—and integrate them into our CI pipelines to catch regressions early.

Documentation : Produce and update clear, concise documentation for codebases, APIs, system architectures and operational runbooks.

Continuous Improvement : Stay updated with industry trends, evaluate new tools and techniques, and recommend changes that boost our application’s performance, security and usability.

What we’re looking for in our ideal candidate

Full-Stack Expertise (5+ years) : Proven experience building and shipping end-to-end web applications with Python / Django and React / Next.js.

Strong Ownership & Autonomy : Takes full responsibility for features and projects, thrives with minimal oversight and drives tasks to completion.

Analytical Thinker : Breaks down complex technical challenges, troubleshoots effectively and delivers robust, scalable solutions.

Meticulous Quality Focus : Writes clean, well-tested code and maintains clear documentation to ensure reliability and maintainability.

Excellent Communication Skills : Conveys technical concepts clearly to both technical and non-technical audiences and fosters collaboration.

Curiosity-Driven Approach : Quickly learns new tools and frameworks, adapts to shifting priorities and embraces evolving project requirements.

Effective Time Management : Juggles multiple initiatives, prioritises tasks wisely and consistently meets deadlines.

Extra Credit

Relevant Industry Expertise : Deep knowledge of the financial sector, especially consumer credit finance and its unique regulations and challenges.

Renewable Energy Background : Proven involvement in renewable energy projects, with hands-on experience addressing the sector’s specific demands and opportunities.

Start-Up & Scale-Up Agility : Demonstrated success in start-up or high-growth environments, thriving on adaptability, rapid iteration and hands-on collaboration.

Our Recruitment Process

Initial Call (30 mins) : A friendly introductory chat with our Talent Acquisition team to learn more about the role, your background and what motivates you.

Technical Discussion (1.5 hrs) : A collaborative session with our senior developers where we’ll review your past projects, dive into architecture and code scenarios, and brainstorm solutions together. Expect an open technical conversation—share your ideas, ask questions and help us sketch out potential features.

Values Interview (45 mins) : A values-based conversation with our Head of Product to explore how your principles align with Hometree’s culture and mission.

Final Interview (45 mins) : A concluding discussion with the Managing Director of Hometree Finance to tie everything together and discuss next steps.
