Frontend Product Engineer (Full Stack) in London

Grow with Treefera. We are a first-mile intelligence platform, delivering granular visibility into the point of origin in global ag & soft commodity supply chains - where risk, cost, performance and exposure are set.

You’ll join a global, cross-functional team that values rigour, curiosity and working close to real-world challenges. Whether your focus is AI, climate, product or operations, you’ll have space to contribute meaningfully and make an impact from day one.

If you’re excited by complex problems and want to help reshape how nature is valued in real-world decision-making, we’d love to hear from you.

Treefera is hiring a Frontend Product Engineer with full stack capability to strengthen delivery capacity in Environmental Intelligence at a point where the team needs greater resilience, broader end-to-end ownership, and faster iteration across product, platform and customer-facing outcomes. This role exists to turn ambiguous ideas into shipped software across UI, API and pipeline work, while helping the team improve how it builds, documents and scales what works.

Your work will help Treefera ship impactful product improvements faster and turn promising ideas into usable outcomes.

Responsibilities, but not limited to:

• Build and maintain software across user interfaces, APIs and supporting pipelines → delivering usable product outcomes end to end.
• Turn emerging ideas into MVPs and proof-of-concepts quickly → enabling faster customer feedback and iteration toward product–market fit.
• Own implementation and architectural decisions within your scope → helping the team move with speed under ambiguity.
• Support work beyond release through maintenance, documentation and operational follow-through → improving reliability and adoption.
• Contribute to how engineering works across the wider team through code review, tooling and practical improvements → raising quality and effectiveness over time.
• Demo and enable work so that product progress translates into commercial and customer impact → helping strong technical work land successfully.

Who you are:

Must-have requirements:

• You are a strong engineer in Typescript, React, and NestJS (or similar) with the judgement to move confidently across application, API and data-oriented work.
• You can operate effectively in ambiguity, making sensible default decisions and progressing work without waiting for perfect structure.
• You communicate your thinking clearly, document approaches well, and collaborate constructively through feedback and code review.
• You are comfortable in a fast-moving startup environment where priorities can shift quickly and delivery pace matters.
• You are confident to use AI development tools without blindly trusting and can clearly explain your choices, trade-offs and outputs.

Desirable requirements:

• Experience in backend development (python/api/data)
• Experience in working with geospatial data

What success looks like:

A strong candidate is deeply fluent in TypeScript and React, capable of building polished, performant UIs while also holding their own across API and pipeline work when needed. They have an eye for product quality, move fast without leaving a mess behind, and are comfortable making frontend architectural decisions without waiting for direction. They communicate clearly, review code constructively, and have a track record of shipping things that customers actually use.

Who you’ll work with:

You’ll report to the Senior Fullstack Engineer and work closely day to day with members across the app and platform engineering teams.

What you’ll gain at Treefera:

• Build something that matters - join a high-growth climate-tech company applying AI, satellite data and quantitative modelling to real-world challenges across global supply chains, commodities and carbon.
• Work on complex, meaningful problems - develop systems that balance risk, resilience, compliance and sustainability, giving organisations a genuine information advantage at global scale.
• Collaborate with exceptional people - work alongside scientists, engineers and operators who are leaders in their fields, combining academic rigour with practical, cross-functional product delivery.
• Ship and grow in a high-trust environment - experiment, iterate and take thoughtful risks in a team that values autonomy, creativity and continuous learning.
• Develop your craft - dedicated space and time to grow your skills toward mastery, tackling technically demanding challenges that push the boundaries of applied AI and environmental data.
• Be rewarded for your impact - competitive compensation, equity options, meaningful benefits, and the opportunity to help shape the future of AI-powered risk and environmental intelligence.
