Verifies client identity for law and property firms
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.
Fraud and regulation are rising, costing the UK economy over £100bn every year; this makes it more difficult for businesses to protect themselves and their clients - individuals like you and me - from fraud and money laundering.
Our co-founders Olly and Jack were led to this area when a friend was defrauded of £25K when buying their first property. At the time, anti-fraud technology didn’t exist, which meant that completing the anti-fraud checks required in these processes was largely manual. These big life moments should be exciting, but instead are often confusing and scary due to the painful process of completing these paper-based checks and the risk of fraud.
Thirdfort helps businesses to facilitate these anti fraud checks so that individuals know they can transact safely and seamlessly with professionals during these big transactions. Our anti-fraud platform provides a secure way for professionals in regulated sectors like Lawyers, Estate Agents and Accountants to transfer funds and verify sensitive information through app based document checks, facial recognition and open banking.
Over 1,500 businesses now trust Thirdfort to verify their clients. We are FCA regulated and have raised over \$33m in capital from leading Fintech investors Breega and Element Ventures, as well as the founders of Zoopla, Funding Circle, Comply Advantage, Tessian, Fenergo and Fidel.
We’re looking for a Tech Lead (IC4) to join one of our product teams and provide strong technical leadership.
This role is ideal for someone who enjoys solving complex problems, owning technical direction within a domain, and helping other engineers grow through mentorship and example. You will play a key role in shaping how we design, build, and evolve our systems, while working closely with Product, Design, and other engineering leaders.
You won’t be responsible for line management, but you will be expected to set direction, raise standards, and take ownership of the technical outcomes for your area.
For this role, we'd love this person to be able to join us in our London office 2 days per week, being together as a team is valuable for us, especially at this stage of growth.
Our engineering teams are cross-functional product teams, made up of engineers with different specialisms working closely with Product Managers, Designers and stakeholders across the business.
We focus on delivering value iteratively while maintaining a high bar for quality, security and reliability. Our ways of working continue to evolve - blending elements of Scrum, Shape Up and continuous delivery and we expect senior engineers to actively influence and improve how we operate.
You actively use AI-assisted engineering tools in your development workflow and can demonstrate how they have improved the way you design, build, test or maintain software.
You have significant experience building and operating production software in a modern engineering environment.
You’ve led technical design and delivery for complex systems or domains.
You’re comfortable working across backend and frontend systems (for example Go, TypeScript, JavaScript, Python).
You have strong knowledge of APIs, data modelling, testing strategies and system design.
You enjoy mentoring other engineers and leading through influence rather than authority.
You can communicate complex technical ideas clearly to both technical and non-technical stakeholders.
You’re comfortable working in a fast-moving, regulated environment where quality and trust are critical.
We’re passionate about supporting your growth and giving you opportunities to work across the stack. Depending on the team, you’ll work with and help shape:
