GTM Engineer in London

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 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.

About the role:

We don’t need someone to keep our CRM tidy. We need someone to build the machine that supports our go-to-market strategy. As our GTM Engineer, you’ll sit in the TechOps team, alongside the people rethinking how Thirdfort operates with AI and automation, and embed day-to-day with our commercial teams (Sales, Marketing, Customer Success). You’ll own the commercial tech stack end to end: Salesforce at the centre, with HubSpot and Zendesk in constant conversation with it, the data that flows through them, and increasingly the automations and AI agents that make manual work just run. Keeping the stack healthy is table stakes. Inventing what runs on top of it is the job. If your instinct when you see a manual process is “I could build something that does this ten times better”... keep reading.

What you'll be doing:

• Build the GTM machine: design and ship workflow automations and AI agents across the commercial funnel - enrichment, routing, handoffs, reporting - so work that used to be manual just runs.
• Pick the right tool for each job (native Salesforce, n8n, APIs, LLMs) and know when to let an automation run and when to keep a human in the loop.
• Own Salesforce and the commercial tech stack: config, fields, layouts, flows, permissions, security, and platform health, reaching for Apex when needed.
• Treat commercial data as a product: hygiene rules, deduplication, data integrity standards, and audit/remediation across commercial systems.
• Run the BAU engine: own the day-to-day support queue for the commercial stack, triaging, fixing and communicating clearly.
• Deliver commercial tooling projects to a defined scope and timeline, partnering with commercial leadership on what the stack should become.
• Make handoffs disappear: build the connective tissue between Marketing, Sales, and CS, so the baton passes cleanly without anyone translating by hand.
• Shape Thirdfort’s AI agenda: partner with the TechOps Lead, act as an AI champion for the commercial teams, and bring GTM lessons back into the central TechOps function.

What we are looking for:

• Experience in GTM, Revenue Operations, or an adjacent technical role. Ideally 2+ years in a high-growth SaaS environment, with a track record of improving how commercial teams work through systems.
• Evidence you’ve built things: Automations, integrations, agents, internal tools, systems that didn’t exist before.
• Hands-on Salesforce administration: you’ve owned an org, you go deep on the back end, and are familiar with Apex.
• Comfortable stitching tools together: APIs, webhooks, no-code platforms (n8n, Make, Zapier or similar), and light scripting.
• Fluent with AI tools and already using them to move faster.
• A systems thinker who sees processes as things to be redesigned, not just maintained.
• Real attention to detail and a low tolerance for messy data.
• A self-starter who owns the outcome, balancing a real BAU workload with projects and builds.
• A clear communicator who’s at home with both commercial and technical people.

If you require any reasonable adjustments during the application or interview process, please let your dedicated Talent Partner know and we'll do our best to accommodate.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analysing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
