Company mission
To provide the data products and workflow needed to deliver continuous monitoring, assurance and risk evaluation to its clients.
Role
Who you are
- Bachelor’s or Master’s degree in Computer Science, Engineering or a related field
- 5+ years of professional experience building fullstack web applications with modern JavaScript/TypeScript
- Strong backend expertise in Node.js/NestJS or equivalent frameworks
- Proficiency in both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, DynamoDB)
- Proven frontend experience developing robust SPAs, ideally with frameworks like React
- Deep understanding of engineering best practices (e.g., separation of concerns, API design, testability, CI/CD)
- Comfortable working in Agile, collaborative environments, owning outcomes rather than tasks
- Strong communication skills—able to align technical decisions with product goals and articulate them clearly
- Autonomous but a team player: you will have ownership, impact and opportunities to show your strength, but ultimately we are all in this together to fulfil Treefera’s mission
Desirable
- Experience in a leadership or mentorship capacity within an engineering team
- Familiarity with AWS infrastructure and cloud-native practices
- Experience working with geospatial data (GeoJSON, Mapbox, Leaflet)
- Knowledge of Python and/or data-heavy backend systems is a plus
- Experience designing or implementing dashboarding components (graphs, charts)
What the job involves
- You are a seasoned Fullstack Engineer with a strong technical foundation and a product mindset. You’ve built scalable systems, led development initiatives, and enjoy mentoring engineers and shaping best practices. You’re comfortable with ambiguity and confident making architectural decisions that balance technical trade-offs with user value
- In this Senior/Lead role, you’ll take technical ownership over core parts of our web platform, guiding implementation from design to deployment, and collaborating across engineering, product, and design to deliver impactful features. You’ll help set technical direction, ensure code quality, and act as a pillar of our engineering culture

Our take
Nature-based assets are increasingly vital for decarbonising the economy, as they are the most efficient means of removing carbon dioxide from the atmosphere. However, the lack of accessible, understandable, and trustworthy data hinders enterprises from investing in these assets at the necessary scale. This issue, along with regulatory changes like the EU Deforestation Regulation (EUDR) and the demand for supply chain transparency, is creating a positive tipping point that underscores the need for reliable nature-based data solutions.
Treefera is an AI-enabled data fabric platform that enhances transparency and accuracy in nature-based asset reporting. It provides 360-degree visibility into the first leg of commodity supply chains by integrating satellite, drone, and ground truth data via advanced AI algorithms. Working across commodities and carbon capture, it collates and organises large data sets into actionable, risk-mitigating insights. Treefera provides essential data products and workflows for continuous monitoring, assurance, and risk evaluation at a fraction of the computing power used in other AI tools and makes previously unseen information concerning real-world assets transparent, usable and defensible.
Serving a diverse clientele, including project developers, biochar producers, carbon credit market players, and bioenergy companies, Treefera covers jurisdictions across multiple regions and over 500 registered forest projects and harvest sites. The platform consolidates extensive environmental and forestry data and integrates with client analytics through an API, ensuring seamless access to critical information. As a global enterprise with operations in the US, UK, Europe, LATAM, and Asia, Treefera is committed to making the true power of nature-based solutions visible to all.
