We’re building a world-class team to redefine knowledge work with AI
Zeno is a legal AI startup building a platform that helps lawyers
research, review, and draft documents with real legal reasoning — not just text prediction
. We’re developing technology that can:
- Search and retrieve statutes, case law, and commentary with high precision.
- Reason step-by-step, applying legal tests and weighing precedents.
- Explain every answer transparently, so lawyers can trace conclusions back to the exact sources.
Where most tools automate surface-level tasks, we’re focused on replicating the way lawyers actually think through legal problems, making depth and trust the foundation of everything we build.
You’re joining an early-stage startup that is already working with leading firms such as
Ernst & Young, HVG Law, Banning
, and many more. Backed with
$3M in seed funding
, we’re now scaling a team of engineers and thinkers who want to solve real problems, drive innovation, and create lasting change in the legal sector.
The role
As a
Full-Stack Engineer at Zeno
, you’ll work across the stack to design, build, and scale features that bring the power of AI into everyday legal workflows. From high-performance backend services in
Litestar (Python)
to polished user-facing features in
Vue.js and TailwindCSS
, you’ll own projects end-to-end and ship systems that balance speed, reliability, and impact.
This is a hands-on role where your work will directly shape how thousands of legal professionals interact with AI — making complex processes simple, fast, and intuitive.
What You’ll Be Working On
- Architect and implement end-to-end features across the product, from backend APIs to frontend interfaces.
- Build robust, secure, and high-performance backend services with Litestar.
- Collaborate with Design Engineers and product leaders to turn requirements into user-facing functionality.
- Optimize data flows, integrations, and infrastructure for scalability and resilience.
- Prototype quickly, validate with users, and scale successful ideas into production.
- Contribute to architecture discussions, DevOps practices, and deployment pipelines as we scale.
What We’re Looking For
- Experienced in both backend and frontend development, with a bias toward backend systems.
- Strong proficiency in Python (Litestar, FastAPI, or similar frameworks).
- Solid experience with Vue.js, TypeScript, and TailwindCSS for building modern web apps.
- Familiarity with cloud infrastructure, CI/CD pipelines, and containerization (AWS, Azure, Kubernetes, Docker).
- A problem solver who enjoys turning complex workflows into practical, scalable systems.
- Comfortable owning features end-to-end in a fast-moving startup environment.
The ride from startup to scale-up
Things will break, priorities will shift, and there won’t always be a playbook. You’ll wear multiple hats, ship fast, and learn faster. Some weeks will feel chaotic, some problems will feel bigger than your role. That’s the nature of the ride from startup to scale-up: if you need stability and structure, this won’t fit. But if you thrive on ownership, speed, and building from zero, you’ll love it here.
Why join us
- Be part of a product-driven team reinventing how legal professionals work.
- Join early and shape the foundation of a fast-growing, high-impact startup.
- Work in a place where hierarchy doesn’t matter — only the best ideas do.
