UK I Fractional Legal Counsel (UK & NY Qualified) in London

About Infinite Lambda

Infinite Lambda is a global data and AI consultancy on a mission to make innovation accessible.

We help organisations build the data foundations and business context they need for enterprise AI to actually work: from modern data platforms to agentic enablement and our software solution, Flowline.

We are a Certified B Corporation, with 7 legal entities around the world, and are proud to nurture a workplace where decent human beings can do their best work.

Curiosity is our default setting, autonomy is non-negotiable, and impact is the whole point.

The role

As our Fractional Legal Counsel, you will be the senior legal partner to our COO, Exec team, and Board.

In a fractional capacity, you will be part of the team, close to the people who win and deliver the work, and trusted to make the calls that keep us keep moving.

We need someone who can start adding value from their first week.

You will handle our most important contracts and legal questions across EMEA, the Americas, and APAC, and set up the templates, playbooks, and processes that let the business handle routine matters with confidence when you are not there.

Being qualified in both England & Wales and the US means you can cover our two largest legal systems directly and coordinate local counsel everywhere else.

You will report to the COO and work closely with our CFO and General Managers, as many of our legal questions (commercial terms, liability, entity structure and governance) sit at the intersection of legal, finance, and operations.

As the business grows, you will also help us decide what our long-term legal function should look like.

This role spans four pillars.

As the role is fractional, focus matters a lot: you will prioritise what only a senior lawyer can do, bring in external support where it makes sense, and build the tools that let the business help itself.

Who you are

We are not looking for a particular CV but for a particular kind of lawyer, namely senior, commercial, honest, and genuinely interested in the work our teams do.

Experience that matters

• Qualified as a solicitor in England & Wales and the US (preferrably), with both qualifications current and in good standing;
• 7+ years' PQE, with training at a leading law firm and in-house experience, ideally in technology, data, AI or professional services;
• A track record of working fractionally, as an interim, or as a consultant lawyer, and of making an impact quickly;
• Strong commercial contracting experience, especially services, technology and Saa S agreements;
• Experience advising on cross-border matters across the UK, EU, and US, with exposure to APAC a plus;
• Working knowledge of data protection, IP, and emerging AI regulation;
• Experience setting up legal processes or being a company's first legal adviser;
• Your own professional indemnity insurance, or cover through your platform or consultancy.
• Your approach
• You prioritise ruthlessly and are clear about what can wait;
• You give clear answers and a recommendation, not a list of risks;
• You build trust with clients, colleagues and leadership because you are straight with them;
• You leave things better documented than you found them, so the business is never stuck waiting for you;
• You bring rigour without bureaucracy. Life is too short for red tape;
• You are aligned with our company values. This matters to us.
• How the engagement works
• 10 days a month with flexibility around specific working hours and with reasonable availability for urgent matters outside of those;
• A shared request channel and a simple tracker so priorities are visible to everyone;
• A regular check-in with the COO to review workload, priorities and whether the agreed working days still fit;
• Additional days agreed in advance, at the same day rate.
• Why work with us
• Being your true self: show up as you are. We work with people for character, not conformity;
• Practising innovation: front-row seat to the rapid evolution of data and AI, and the legal questions that come with it;
• Living autonomously: remote-first, with flexibility on how you structure your days;
• Real influence: a senior voice in a growing global business, working directly with the COO and Exec team.

We are a Certified B Corporation.

That means we measure ourselves not just by what we deliver, but by how we deliver it because of our people, our clients, our communities, and the environment.
