Senior Software Engineer

? English required

About us

We build the measurement layer for agricultural sustainability: carbon footprints for the livestock industry using our own certified models, biodiversity assessment from remote sensing, and emissions reduction planning. Our customers are agri-food processors and cooperatives measuring and reducing the environmental impact of thousands of farms. We're a small, science-led team past MVP, with paying customers in production and an engineering team of five.

The role

We're looking for a senior engineer who ships, and who has been through a scaling phase before. You've seen what breaks as a product and team grow, and you know what's worth getting right early.

This is a hands-on individual contributor role. Most of your time goes into building and shipping across our platform. Alongside that, you'll bring your experience to how we work: code review, our deployment pipeline, and architecture decisions. Most of our engineers are early in their careers, so the way you build and review will be a big part of how they learn.

What you'll do

- Build and ship features and improvements across our APIs, data processing and model services
- Contribute to our code review standards, and help raise quality as AI-assisted development increases our output
- Help make our deployment pipeline faster and safer
- Bring your experience to architecture discussions as we scale
- Help expand automated testing and monitoring





What we're looking for

Essential

- 5 to 8 years building and shipping production software
- You've worked at a company through a period of real growth, in customers, team or both. You saw which practices held up, which broke, and what you'd do differently
- Solid backend experience in a modern ecosystem (TypeScript/Node, Python, Java, Go or similar), REST APIs and relational databases
- Practical experience with CI/CD, automated testing and running software in the cloud
- You've regularly reviewed other engineers' code and enjoy helping others improve

Nice to have

- Experience with Azure, NestJS or Python data processing
- You use AI across your workflow to improve quality and testing, not only to write features faster
- Experience with calculation-heavy systems where the output has to be correct, not just available

You don't need agriculture, carbon footprint or LCA knowledge. That's our domain, and we'll teach you.

Our stack

React · Node.js/NestJS · Python (models, ETL, microservices) · PostgreSQL · GDAL/rasterio · GitHub & GitHub Actions · Azure · Claude Code, OpenAI API

Details

- Location: Valencia, hybrid. You'll need to be based here or willing to relocate.
- Compensation: Based on experience
- Interview process: Intro call -> Interview with Chief Product Officer -> Technical Interview with engineers -> Offer

We're committed to building a diverse team and welcome applicants from all backgrounds.
