Software Engineer (Full Stack, Mid-Level)

🌱 Our Mission

At Treeconomy, we believe in the regenerative power of nature. We’re on a mission to combat climate change, restore ecosystems, and improve livelihoods.

By embracing remote sensing technology and financial innovation, we are revolutionising the forest carbon market and incentivising landowners to grow flourishing, climate-positive forests. We have massive goals and are looking for passionate people to help us achieve them.

🚀 Our Company

Treeconomy is a venture-backed earth-tech startup working at the intersection of technology, ecology, and finance.

We were founded to close the $700B annual nature funding gap, scaling impactful nature-based solutions to realise true win-win-wins for climate, biodiversity, and human livelihoods. We harness remote sensing, machine learning, platform technology, and deep carbon markets expertise to bring traceability, transparency, and trust — and with it, funding — to truly impactful carbon-removing restoration efforts.

We support rural landowners and natural capital investors with financing, measurement, and monitoring services, connecting the highest-quality projects to leading corporate carbon buyers and investors via our platform.

✨ The Role

We’re hiring a Mid-level Full-Stack Engineer (Contract) to accelerate development on Sherwood — our primary platform for engaging project developers (and soon, buyers and other stakeholders). Sherwood houses all project data and is where we publish monitoring, reporting, and verification outputs; it’s the place we “do everything” for projects.

You’ll be a JavaScript-first full-stack engineer (React/Next.js on the frontend, Node.js on the backend) who is deeply product-oriented and comfortable making pragmatic technical decisions in a whirlwind startup environment. You’ll collaborate closely with Product and Design, translate Figma into usable, fast, and elegant interfaces, and own performance and architectural improvements that move the needle for our users and the business.

Primary objectives for your first 90 days

• Ship the next version of our monitoring reports — a major upgrade to three reports and countless insights that help developers get projects off the ground and into validation.
• Improve flexibility of platform architecture — ensure that we can serve responsive content on the platform for a host of new configurations to our existing products.
• Build the UX foundations for Sherwood — a components library and information architecture that will make Sherwood the place where customers return to add data and gain insights on their projects.

High-priority user journey: Interacting with and understanding reports.

You will report to our Product Lead and work closely with Engineering and Design. This is a semi-autonomous IC role with the chance to make a large contribution to our product as part of a small, high-impact team.

🌳 Your Profile

• Technical & Scope — You independently deliver moderate features end-to-end across React/Next.js (building accessible, responsive components, sensible data-fetching) and Node.js (clear handlers, error states). You understand Sherwood’s architecture well enough to fit work neatly into it, and you’re comfortable contributing to a shared component library and information architecture.
• Autonomy — You anticipate blockers (ambiguity, dependencies, performance pitfalls) and propose incremental improvements (small refactors, dependency updates, pattern tidy-ups) that reduce risk without derailing delivery. You ask sharp questions early and surface risks in time to adjust scope.
• Product Orientation — You balance user needs with technical feasibility. You care about the usability of reports and can explain trade-offs (e.g., SSR/ISR/client) in plain English. You keep an eye on performance and accessibility as part of “done,” especially for the reports experience.
• Delivery — You communicate proactively in Slack/Notion, keep PRs small and reviewable, write crisp documentation, and hit agreed milestones—or renegotiate early with options. You test what matters (critical paths, loading/error/empty states) and verify outcomes.
• Collaboration — You pair program when useful, give constructive code reviews, and work smoothly with Product and Design (turning Figma into clear UI and asking for clarification when intent is ambiguous). You’re feedback-friendly and help teammates move faster.
• Strategic Leadership — You contribute ideas that influence our approach (component patterns, modest architecture tweaks), and you participate in lightweight design discussions/RFCs—without needing to be the final decision-maker.

Must-haves

• Solid experience with React + Next.js and Node.js, delivering features in production.
• Ability to translate Figma designs into accessible, responsive, well-structured components.
• Evidence of proactive communication and clear documentation (Notion, PRs, Linear).
• Demonstrated product sense: can discuss user impact and pragmatic trade-offs.
• Comfortable improving performance and reliability as part of everyday work.
• Ability to operate in a startup environment: ambiguity, fast iteration, and principled trade-offs.
• Experience working with geospatial data in the context of delivering a product to non-technical users.

Nice-to-haves

• TypeScript proficiency.
• Experience contributing to or establishing a components library/design system.
• Familiarity with performance tooling and targeted testing (unit/integration/E2E where it counts).
• Exposure to data-heavy UX.
• Prior startup experience (shipping under ambiguity, iterative releases).
• Proficiency using AI tooling to speed up engineering workflows while maintaining high quality standards for code.
• Exposure to climate, Monitoring Reporting and Verification, or the Voluntary Carbon Market.

🧰 Tech Stack & Collaboration

• Frontend: JavaScript, TypeScript
• Backend: Node.js, Python
• Collab & delivery: Slack, Notion (docs), GitHub (PRs), Linear (tickets), Figma (design)

You’ll focus on the frontend and backend application layers. Geospatial, heavy data engineering, and DevOps are handled by other specialists — you’ll collaborate with them as needed.

🌍 Location & hours

• UK-based, with core hours 10:00–16:00 for collaboration. This is essential, as we are government funded and must support UK workers as a requirement of the funding.
• Remote-friendly. Ability to travel to London, as needed.

📄 Contract

• Engagement: Fixed Term Contract (inside IR35)
• Time commitment: Full-time (5 days/week), initial 6-month term. We anticipate extending this into a permanent contract upon successful completion of the project.
• Start date: ASAP.
• Pay guidance: £50-60k annual equivalent.
• Equipment: A company laptop can be provided.
• Right to Work: Due to funding restrictions, we can only consider applications from UK residents with an existing right to work in the UK.

🤝 How we work together

We value engineers who bring clarity. You’re comfortable stating what’s true — especially when it’s inconvenient — and explaining what’s happening, why it matters to users and the business, and what you recommend next. You favour simple, well-tested solutions and steady delivery over clever complexity.
