Role Overview

We are looking for a Principal Researcher to join Monoliths Research team. This is a high-impact high-ownership role for a researcher who combines deep technical expertise with the ability to lead complex multi-stakeholder projects from first principles through to production.

You will be among the most senior technical voices in the organisation contributing to research direction establishing high standards through your own work and providing meaningful technical guidance across the team while remaining a hands-on contributor to the most challenging and consequential projects.

You will work closely with engineering product and client-facing teams driving cross-functional alignment on complex research initiatives in collaboration with some of the worlds most advanced engineering R&D organisations. The role demands rigorous scientific thinking strong execution and the interpersonal credibility to bring diverse stakeholders along.

What Youll Do

Research Leadership & Strategy

• Contribute meaningfully to Monoliths research direction by identifying high-leverage open problems and advocating for the approaches most likely to have real-world impact.
• Originate novel research directions not just applying the state of the art but advancing it in ways that are meaningful for real-world engineering applications.
• Evaluate emerging fields and paradigms providing well-grounded technical judgement on which advances are worth pursuing and why.
• Champion rigour reproducibility and scientific integrity across all research outputs.
• Represent Monolith in the external research community through publications conference contributions and engagement with leading academics and industry researchers.

Technical Depth & Execution

• Lead the design and development of sophisticated ML systems for complex high-dimensional engineering data taking end-to-end ownership from problem framing through production deployment.
• Drive technical decisions on the most difficult modelling problems including novel approaches to generalisation uncertainty robustness and out-of-distribution performance.
• Orchestrate the delivery of large cross-functional research projects aligning engineering product and research contributors around clear technical goals and milestones.
• Advance Monoliths capabilities in agentic and autonomous ML systems from foundational design through to deployment at scale.
• Maintain deep personal technical expertise; remain a hands-on contributor to the most critical and novel technical work.

Organisational Influence & Mentorship

• Serve as one of the most senior technical voices in the research organisation providing guidance and review on significant technical decisions and helping shape team-wide standards.
• Mentor and develop senior researchers sharing experience and raising technical quality across the team.
• Contribute to research practices and norms that improve how Monolith approaches complex problems consistently and rigorously.
• Build strong cross-functional relationships with engineering product and client-facing teams to ensure research work lands with real impact.
• Communicate technical work and its implications clearly to a range of audiences from close collaborators to senior leadership and external partners.

Technical Focus

• Foundational and applied machine learning for engineering and physical systems
• Generalisation robustness and out-of-distribution performance in real-world ML
• Probabilistic modelling uncertainty quantification and calibration
• Time-series high-dimensional and structured scientific data
• Agentic and autonomous ML systems
• End-to-end ML systems: data pipelines through production deployment and monitoring
• Research methodology experimental design and scientific reproducibility

What Were Looking For

• 12 years of experience in ML research applied AI or a closely related field with a demonstrated track record of foundational or highly impactful technical contributions.
• Recognised expertise in one or more core areas of machine learning with the breadth to operate credibly across the full spectrum of Monoliths technical landscape.
• A portfolio of research contributions publications patents open-source work or internal breakthroughs that have shaped how others work.
• Exceptional engineering foundations in Python with deep experience designing and shipping production ML systems in collaborative codebases.
• Demonstrated ability to both lead technical direction and execute on it driving complex projects end-to-end while bringing others along.
• A track record of mentoring and growing senior technical talent.
• The ability to operate with clarity and influence at all levels from first-principles technical debate to executive communication.
• Comfort working in high-ambiguity environments where the right problem is often as important as the right solution.
