Senior Ruby Developer

We’re Avvoka

Join us in building the next generation of legal drafting technology.
We help teams move faster through complex contracts using automation, collaboration and AI — with lawyers firmly in control.

Trusted by leading law firms, banks and enterprises, we’ve grown rapidly through product strength and word of mouth. Now, we’re scaling from a product-led company into a global brand.

You’ll help shape the design, storytelling and experiences that define the next era of drafting.

Why Join Us

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.

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.

You’ll work on complex, high-impact projects, architecting solutions, improving system performance, and delivering features that our users rely on every day. This is a chance to shape the codebase, influence product direction, and contribute to a collaborative, fast-moving engineering culture.
