Senior Software Engineer - Hybrid/Remote F/M/X
We’re building out the technical heart of Sand to Green, the agri-tech impact venture behind the RegenWise platform — and we have one senior engineering seat left to fill.
Sand to Green’s mission is to scale regenerative agriculture globally. Our SaaS product, RegenWise, helps assess, design, and monitor ecosystem-restoring farming systems using satellite, soil, and climate data. We work hand-in-hand with top research institutions like CIRAD.
We’re looking for a senior software engineer who can join us, either part time to start with, then full time, or immediately full time. The contract will be under exploration with you, either a freelancing contract, CDD and CDI contract, with the goal of turning it into a CDI contract. The right person is someone who has strong experience in backend development, API-first environments, and modern web app architecture — and who cares about impactful, mission-driven work.
Your role
- Ship core features: data ingestion, geospatial views, forecasting, MRV, dashboards
- Extend and improve our Django backend monolith application keeping it scalable
- Work in an API first environment, proactively identifying new datasets and data improvements
- Design scalable data models and improve performance and reliability (latency, parallel tasks, retries)
- Strengthen CI/CD pipelines and engineering best practices
- Collaborate with agronomists and PM to turn agro-concepts into computational models
- Guide architectural decisions for product scale and reliability
- Work with satellite-derived and geospatial datasets
- Adapt our product to the needs of our clients.
Why joining us?
- Real product: not a concept, or idea-stage project
- Field-tested: help build a scientifically credible & field tested product
- Impact: your work benefits regeneration, farmers, and climate resilience.
- High autonomy: shape architecture, engineering culture, and long-term decisions.
- Flexibility: start part time + remote if it better suits your needs.
- Real-world challenges: we’re talking about real farms, biodiversity & nature.
Our tech stack
- Backend: Python, Django, PostgreSQL + GeoDjango, Mypy, Flake8 (typing + linting), Folium
- Frontend: HTML, JavaScript, Tailwind + DaisyUI, Alpine.js
- Infrastructure: GitHub Actions, PythonAnywhere, Google Cloud, Sentry
Skills
- 7+ years of software engineering experience in backend / data-heavy systems
- Skilled in building scalable SaaS platforms, ideally with spatial / geodata components
- Comfortable working cross-disciplinarily with scientists, agronomists, and product
- Strong expertise in API-first environments, understanding of latency optimization and parallelization, ability to handle complex data models
- Comprehension of satellite analytics or geospatial workflows (bonus)
- Experience in early-stage or impact-driven companies (bonus)
- Passionate about climate tech, regenerative agriculture, and building for long-term ecological impact (bonus)
- Full stack experience is a plus
Compensation
Competitive compensation (based on experience) + meaningful ownership in a mission-driven company + BSPCE
