🌍 Founding Machine Learning Engineer – Climate tech
đź“Ť London preferred, remote considered (UK-based)
🚀 Early-stage | High ownership | Real-world impact
About the Company
We’re an early-stage technology, our platform makes unstructured documents searchable, explainable, and useful - giving users the insights they need to make faster and more informed decisions.
We’re building a founding team of engineers who are passionate about solving meaningful real-world problems in the climate-tech space using cutting-edge AI. We’re already working with forward-thinking organisations and are now focused on scaling the next version of the product.
The Opportunity
We're looking for a Founding ML Engineer to join our small, mission-driven team. This is a rare chance to build systems from the ground up, define the product alongside users, and work with modern ML tooling - not just in theory, but in production.
What You’ll Do
* Build RAG-Based Systems: Design and implement production-ready retrieval-augmented generation (RAG) pipelines powered by LLMs and vector search.
* Develop ML Infrastructure: Create scalable, modular ML systems for parsing and interpreting long-form unstructured documents.
* Collaborate Closely with Users: Work directly with internal and external stakeholders to refine use cases and deliver high-utility outputs.
* End-to-End Ownership: Operate across the stack—from model experimentation to integration with APIs and UIs.
* Influence Culture & Direction: Help shape technical standards, processes, and company culture as a key early team member.
Who You Are
* Applied ML Engineer: Experience building ML-driven applications using LLMs, with an emphasis on real-world deployment rather than just experimentation.
* Strong with Vector Tech: You’ve worked with vector databases and know how to structure embeddings and retrieval for scalable performance.
* Startup-Minded: You’re comfortable wearing multiple hats and navigating ambiguity with a bias toward action.
* Curious & Fast-Learning: You pick up new tools quickly, iterate fast, and are thoughtful about technical tradeoffs.
* Mission-Aligned: You care about creating tech that solves important problems in a responsible and lasting way.
What We’re Working With
* We’re early-stage and flexible, but current tools include:
* Python (and typical ML ecosystem)
* Vector databases
* Open-source and API-based LLMs Retrieval frameworks (e.g., LangChain, LlamaIndex)
* Cloud-native infra (AWS)
We care more about your ability to learn and execute than ticking every tech box.
Why Join
* Shape the Future: Join at the ground floor and influence everything from the product roadmap to team values.
* Mission-Driven Work: Build tools that help organisations make better decisions in complex domains.
* Work Autonomously: High trust, high impact environment with real ownership from day one.
* Growth-Oriented: Work closely with experienced founders and early users to rapidly develop your skills and career.
