Job Description
Founding ML Engineer / Founding Head of Engineering - London- £120,000
Seniority: First senior technical hire
Focus: Reasoning engine design, data strategy, early engineering team building
Role Overview
You will serve as the company’s founding technical leader, architecting a reasoning and simulation engine that models how buildings are constructed. The role blends applied machine learning, data architecture, knowledge-graph design, and organizational leadership. You will help define the technical roadmap through seed stage and lay the foundation for a future Series A engineering organization.
This position requires comfort with ambiguity, strong product intuition, and the ability to translate real-world construction workflows into computational systems. You’ll work directly with field teams to ensure models reflect practical construction realities.
Key Responsibilities
Technical
- Build end-to-end data pipelines for, cost catalogues, and historical project information.
- Select, train, and fine-tune models for sequencing and dependency prediction
- Develop multimodal embeddings that unify text, geometry, schedules, and metadata.
- Implement continuous-learning loops using simulation outputs and field feedback.
- Lead research on construction knowledge representation, ontology design, and explainable reasoning.
- Collaborate with platform and simulation engineers to integrate models into wider platform
- Design multi-agent reasoning systems powered by a shared knowledge graph.
Leadership
- Operate as the founding technical leader prior to CTO hire; then report to the CTO.
- Define hiring needs and recruit the initial engineering team.
- Establish early engineering processes (sprints, documentation, compliance, road mapping).
- Convert customer and field insights into product and model requirements.
- Represent the technical vision with early partners and construction stakeholders.
- Contribute to a culture centred on collaboration with manual workers
Requirements
- 8+ years of experience deploying ML systems in production (start-up or fast-iteration environment strongly preferred).
- Experience leading teams or cross-functional AI/ML initiatives with PM-style responsibilities.
- Advanced proficiency in Python and modern ML frameworks
- Strong background in data architecture and knowledge graphs.
- Strong education from top university
Bonus:
- familiarity with 3D Vison model / construction data or something similar
- Track record of combining research with solid engineering practices.
- Graduate training in AI, robotics, or computational design is a plus.
- digital-twin work highly beneficial
