We’ve already protected over 3 million people through life’s big transactions.\nFraud 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.\nOur 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.\nThirdfort 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.\nOver 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.\nAbout the role:\nWe’re looking for a Tech Lead (IC4) to join one of our product teams and provide strong technical leadership.\nThis 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.\nYou 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.\nFor 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.\nAbout the team:\nOur 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.\nWe 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.\nAs a Tech Lead, you will:\nProvide technical leadership within your team and domain, guiding design decisions and architectural direction.\nDesign, build and deliver complex features and systems that are secure, scalable and maintainable.\nOwn technical outcomes end-to-end, from discovery and design through to delivery and long-term operation.\nLead by example in AI-assisted software engineering, using AI to accelerate delivery while maintaining strong engineering judgement and accountability for the resulting software.\nHelp the team continuously improve its AI-enabled development practices and identify opportunities to automate repetitive engineering work.\nRepresent Engineering at an organisational level, partnering with stakeholders across Product, Sales, Marketing, Support, Operations, Legal and Compliance to shape decisions, manage trade-offs and drive successful technical outcomes.\nMentor and coach engineers across the team, supporting their technical growth and confidence.\nSet a high bar for code quality, testing, observability and operational excellence.\nCollaborate closely with Product and Design to shape solutions, challenge assumptions and manage trade-offs.\nLead technical discussions, reviews and incident investigations, helping the team learn and improve.\nContribute to wider engineering initiatives and influence standards across the technology organisation.\nWe’d love to hear from you if:\nYou 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.\n\nYou have significant experience building and operating production software in a modern engineering environment.\n\nYou’ve led technical design and delivery for complex systems or domains.\n\nYou’re comfortable working across backend and frontend systems (for example Go, TypeScript, JavaScript, Python).\n\nYou have strong knowledge of APIs, data modelling, testing strategies and system design.\n\nYou enjoy mentoring other engineers and leading through influence rather than authority.\n\nYou can communicate complex technical ideas clearly to both technical and non-technical stakeholders.\n\nYou’re comfortable working in a fast-moving, regulated environment where quality and trust are critical.\n\nWe use and teach:\nWe’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:\nGo for backend services\nTypeScript and React for web applications\nReact Native for mobile applications\nTemporal for workflow orchestration\nPostgreSQL for relational data\nGCP for infrastructure, monitoring and analytics\nAI-assisted engineering tools and coding agents to help us design, build, test, review and maintain software more effectively.\nOur Benefits:\nWe've created our benefits package to reflect Thirdfort's mission and values. Everything we do is designed to build on trust, and we extend this promise to our team by investing in their physical, mental, and financial security to support them through life's big moments. Ultimately, our benefits exist to empower our people, ensuring everyone feels deeply supported, trusted, and equipped to do their best work.\nWhen you join Thirdfort, you'll get immediate access to our employee benefits package that aims to support you across these areas:\nCompensation: £100,000 +\nShare options for all UK employees\nAnnual leave allowance of 26 days, increasing to 30 with tenure and the option to buy additional days\nUncapped personal development budget\nFlexible working hours\nPrivate healthcare (AXA)\nEnhanced parental and sick leave\nWe're committed to building an inclusive, equitable and diverse culture where everyone has a chance to make a difference. We're purposefully building a team of problem-solvers that reflect our values, which is why we hire from all backgrounds. If you're a curious, kind individual who takes ownership, you'll be a great Thirdforter.\n 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.","description_format":"text","description_chars":6987,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Flexible schedule","Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Identity Management","RegTech, AML & Compliance"],"lifecycle":[{"event":"open","at":"2026-10-14T17:35:34Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-10-14T06:20:30+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":32,"band":"fade","label":"Fading","p_open":1,"p_active":0.586,"p_room":0.55,"age_days":33,"expected_fill_days":24,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-14T22:31:50Z"},"pay":{"stated_usd_annual":131489,"is_top_pay":false},"html_url":"https://alion.io/job/thirdfort-tech-lead","json_url":"https://alion.io/job/thirdfort-tech-lead.json","meta":{"generated_at":"2026-10-14T22:31:50Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":30350,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":172476},"rest":"https://alion.io/mcp/rest/get_company?id=172476"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fthirdfort-tech-lead"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fthirdfort-tech-lead"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fthirdfort-tech-lead"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/thirdfort-tech-lead\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fthirdfort-tech-lead"}]}
