About Rainforest Builder
Rainforest Builder is Africa’s leading forest restoration company, on a mission to restore one million hectares of degraded land to natural tropical forest. By combining world-leading science, forestry, and tech, we are able to deliver high-quality forest restoration at unprecedented scales.
Our projects work to remove hundreds of millions of tonnes of CO2 from the atmosphere, reverse declining biodiversity trends, and deliver equitable economic growth to rural communities. We currently operate four projects across three countries in West Africa, and are continuing to expand to new areas within the region.
To unlock restoration at scale, we are working to build best-in-class software enables highly-distributed operations, manages data flows through the business, and, ultimately, delivers high-integrity data into the hands of stakeholders and other third parties.
Role Overview
As a Senior Product Engineer at Rainforest Builder, you will take full responsibility for an operational domain within our organisation. You’ll be the one clarifying the problem, finding the solutions, and executing the delivery. Pre-LLMs, this would have been Team Lead, but the way we work is shifting. It’s now possible for high-skill, high-agency individuals using the latest tooling to perform the work a team used to do. We want to strip back the process that slows down dev teams, and give great people an objective and let them execute.
This means we need people who are excited at the prospect of owning both product and technical implementation, and working with high agency to deliver. You will have the support of key business stakeholders, but will be expected to build relationships within the business in order to understand the problem you are solving. The ideal candidate will have both a strong technical foundation and a product mindset, and the ability to solve an issue across the full technical stack.
The ideal candidate will be highly motivated and looking for real-world impact: building software to enable projects that restore biodiversity, deliver equitable economic growth to rural communities, and remove greenhouse gas at scale.

* Collaborate closely with Business owners, employees and staff in the field to establish solutions to problems within your domain area.

* Build software with tangible, real-world environmental and social impact.
