Technical Writer

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 and Sydney. We have raised more than $500m in funding and are now valued at $2.7bn. 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.

At Thought Machine, we’ve built a single, unified home for our technical content. As a Technical Writer, you’ll be the key to making our documentation and learning materials the best of their kind.

• Use feedback to redesign clunky sections and help evolve our documentation site into a world-class resource.

• Help us refine our style guides and maintain our "docs-as-code" approach.

Requirements

• You’ve got a solid background in technical writing, ideally using a docs-as-code approach.

• You’re comfortable working with Swagger and OpenAPI.

• You have experience producing diagrams and videos, and understand when they are required.

• You enjoy breaking down complex concepts into digestible, step-by-step learning materials.

• You’re self-motivated and comfortable managing your own time in a fast-paced environment.
