Wfh jobs in United Kingdom

We build legal drafting technology for moments that matter – when the stakes are high, the documents are complex, and speed can’t come at the cost of control.

Our platform helps legal teams move faster through contracts using automation, collaboration, and AI – without taking judgment away from the lawyers who own the risk. We believe technology should amplify expertise, not replace it.

Avvoka is trusted by leading law firms, banks, and global enterprises, and we’ve grown through product strength and word of mouth alone. With headcount and revenue increasing by over 70% year on year, we’re now scaling from a product-led success into a globally recognised legal-tech brand.

We’re at an inflection point: evolving how the world’s most sophisticated legal teams work – and building a company where thoughtful people can do the best work of their careers.

Why Join Us

This is a rare opportunity to help build cutting edge tools from the ground up – not inherit them. You’ll be part of a small, ambitious team with the freedom to create, experiment and raise the bar for legal tech.

You’ll work alongside smart, supportive people who move fast and care deeply about quality. If you’re motivated by ownership, pace and visible impact, you’ll feel at home here.
