Senior Technical Product Manager - Vault Core

Thought Machine's mission is bold – to properly and permanently rid the world's banks of legacy technology. To achieve this, we have developed the foundations of modern banking through core and payments technology which run natively in the cloud. What we are attempting is hard and means we need great people working together to build great technology.

We have grown rapidly in the past few years – growing our team to more than 550 individuals across offices in London, New York, Singapore, Sydney and our newly established Engineering Hub in Lisbon. We have raised more than £500m in funding and our investors include Molten Ventures, Eurazeo, Intesa Sanpaolo, Temasek, Nyca Partners, JPMorgan Chase Strategic Investments, Standard Chartered Ventures, and more.

We have created a culture that enables our team to produce the best work in the industry while ensuring we have fun along the way. We're regularly cited as having a fantastic workplace culture and have been recognised by Sifted magazine as having one of the highest Glassdoor ratings for a UK fintech company and the industry's most generous employee share package. Named one of the world's most innovative fintechs by Global Finance Magazine, we were also recognised by the Financial Times as one of Europe's fastest-growing companies for two consecutive years—and a UK Best Employer for 2026.

Vault Core is our flagship core banking platform, designed to run any bank product, from mortgages and savings to complex corporate lending using our unique, Python-based Smart Contracts. Today, more than 50 clients, including multiple systemically important Tier 1 banks, run their most critical banking workloads on Vault Core. This platform can be self-hosted by clients or consumed as a SaaS offering operated by Thought Machine, with support across major cloud providers such as AWS, GCP, and Azure.

This role is highly technical.

This role is ideal for someone who thrives at the intersection of deeply technical domains and high-level product strategy, with good commercial instincts. You understand that your clients’ success depends on a platform that is not just functional, but has best-in-class design, is performant and resilient. By building alignment across Engineering, GTM, and Customer Success, you will ensure that platform capabilities drive adoption and deliver measurable outcomes.

• Experience working in regulated industries such as banking or financial services
