Join an early-stage sustainability software company and help enterprise customers turn messy data into usable information for reporting and operational decisions. We're looking for 4 engineers for this project.

You’ll help customers get up and running, build tools that simplify onboarding, and ship full-stack features that solve problems you uncover along the way. You’ll work directly with users and get regular feedback and code reviews from senior engineers, with scope to lead implementations as you grow.

What you’ll do

- Help onboard enterprise customers by cleaning, mapping, validating and loading data from spreadsheets, PDFs and business system exports.
- Work with customers and the data team to understand workflows, spot data quality issues and explain what needs fixing.
- Build scripts, validation checks and internal tools that make each onboarding easier to repeat.
- Ship features and fixes across the TypeScript, React and Node.js stack, especially when customer implementations reveal gaps in the product.
- Use coding agents daily. Write explicit specs, review generated code,



verify it with tests and explain the changes you ship.

What you’ll bring
- Early-career engineering experience, typically up to two years, or a strong record of projects you’ve built and shipped.
- Working knowledge of TypeScript and React or Next.js, plus some backend experience with Node.js.
- Solid SQL fundamentals and comfort writing scripts in TypeScript or Python to clean and transform data.
- Practical experience using tools such as Claude Code, Codex or Cursor on a real project. You can explain where the tool helped, what it got wrong and how you checked its work.
- Attention to detail with data and clear communication with both technical and non-technical users.

Experience with messy datasets, customer-facing work, AWS or Supabase is welcome.

To apply, send your CV and a short example of something you’ve built or shipped. Tell us what you owned and how you verified that it worked. Examples from work, study, freelance or personal projects are welcome.
