Senior Javascript Engineer at Avvoka
Worldwide
<h2><strong>We’re Avvoka</strong></h2><p>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.</p><p>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 <em>amplify expertise</em>, not replace it.</p><p>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.</p><p>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.</p><h2><span><strong>Why Join Us</strong></span></h2><p><span>This is a rare opportunity to build the Avvoka brand from the ground up — not inherit it. You’ll be part of a small, ambitious team with the freedom to create, experiment and raise the bar for legal tech.</span></p><p><span>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.</span></p><h2><span><strong>The Role</strong></span></h2><p>You’re a technically strong<strong> JavaScript </strong>engineer who enjoys tackling hard engineering problems.
