Thirdfort is a client due diligence platform used by over 1,500 regulated businesses, including law firms, estate agents and accountants, to verify their clients and meet their anti-money laundering obligations. That makes this an unusual in-house role: you’ll lead legal for an FCA-regulated business whose platform is used by compliance teams, at a time of significant change in how our customers are regulated.

We’re on a mission to protect society from fraud and money laundering. We’ve already protected over 3 million people through life’s big transactions, with a core aim to protect 3.5 million people by the end of 2026. Our co-founders Olly and Jack started Thirdfort after a friend lost £25,000 to fraud while buying their first property.

Our platform brings together ID verification, AML screening, know-your-business and source of funds checks, and in February 2025 we acquired Homeppl’s rental check platform. Our platform brings together ID verification, AML screening, know-your-business and source of funds checks, and in February 2025 we acquired Homeppl’s rental check platform. We are FCA-regulated and have raised over $25m in capital from leading fintech investors Breega and Element Ventures, as well as the founders of Zoopla, Funding Circle, ComplyAdvantage, Tessian, Fenergo and Fidel. We have teams in London and Manchester.

The Role:

We're seeking a dynamic, solutions-oriented commercial lawyer to lead our Legal team. The Legal team has been integral to Thirdfort's growth story, working closely with the founders, C-suite, and all teams across the business to help achieve our goals and reports to our COO. This is a step up: it suits a senior lawyer who is ready to run a legal function.

This role is varied, fast-paced, and demanding, you'll balance needs from across the organisation, stay at the forefront of regulatory and industry trends, and help the business manage legal risk. You'll set the legal strategy, whilst also being comfortable zooming in, getting hands-on yourself and you’ll use AI, technology and smart ways of working to keep the function lean and effective as we grow.

Why join now:

You’ll have real scope to shape how Legal works and, as Thirdfort scales, for the right person to take on a broader, more strategic role over time. Legal is currently a lean in-house function using AI legal tools, with external specialist support. We’re also looking to recruit an aditional lawyer, who will report to you.

Our platform is used by compliance teams in regulated businesses. How we handle their data, contract with them and respond to changes in their regulation is part of what they buy from us.

Responsibilities:

Provide strategic legal advice to the COO, Co-Founders, C-Suite and broader leadership team as required, and set the legal team’s objectives as part of company planning
Manage and develop the legal team as it grows
Support Commercial teams to manage and close a wide variety of commercial deals with clients and partners, and own playbooks and templates so standard deals close quickly
Give commercially minded regulatory and compliance advice, including on our FCA authorisation, and track changes affecting us and our customers
Act as product counsel on new features, integrations and the use of AI
Negotiate and manage the strategic data and identity supplier agreements that underpin our platform, alongside other technology and vendor contracts
Lead our data protection programme across Thirdfort and Homeppl and the governance of AI in our product and ways of working
Work with the founders and external counsel on fundraising and M&A
Manage disputes and litigation with external counsel
Provide day-to-day advice on employment, corporate governance, compliance and insurance

You might be a great fit if you:

Are a qualified solicitor (England and Wales) with at least 6 PQE in house and/or private practice, and are ready to lead a legal function, perhaps for the first time
Have strong commercial and technology contracting experience, with hands-on data protection work in a product setting, ideally in a start-up or scale-up
Have worked in a regulated business, ideally in financial services, payments, fintech or regtech, and are comfortable owning regulatory filings and compliance processes alongside legal work
Are an excellent communicator and negotiator, able to explain legal issues clearly to the rest of the business, at pace
Are hungry to learn about the world of fraud and money laundering, AML experience is a plus, but not essential
Are pragmatic, output focused and enjoy working with colleagues from different teams and backgrounds
Are passionate about Legal Ops, AI and using technology to keep legal lean and high-impact
If this role excites you, we’d still like to hear from you
