Better Auth is a comprehensive authentication framework for TypeScript that lets you implement everything from simple auth flows to enterprise-grade systems directly on your own database, embedded in your backend. It’s loved by developers all over the world and endorsed by leading voices in the ecosystem.

On top of the framework, Better Auth also provides an infrastructure layer to help you scale with user management and analytics, bot and fraud detection, transactional email and SMS, global session storage and more.

About us
We’re a tiny group of engineers on a mission to democratize high‑quality authentication and make auth something every developer can truly own.

Our open‑source framework is already one of the fastest‑growing auth solutions in the world. It’s trusted by thousands of developers and is rapidly adopted by startups and YC companies alike.

We’ve been moving fast - TechCrunch recently featured our story: Better Auth, an authentication tool by a self-taught Ethiopian dev, raises $5M from Peak XV, YC
We also launched on YC Launch and became the most upvoted YC Launch in YC’s history: Better Auth on YC Launch.

We’ve grown our community and impact faster than our team and now we’re looking to align the two quickly.

What you’ll work on here

• Collaborating across backend, frontend, and design to ship features that make developers’ lives easier
• Building at the edge between frontend and backend with TypeScript, React, and Node
• Owning features end‑to‑end, from concept to production deployment
• Managing and improving our plugin ecosystem for developers
• Mentoring junior developers and contributing to planning and review sessions

Why you should join Better Auth

You’ll enjoy high ownership and join a team that’s still early but already making a huge impact. You’ll work deeply on developer experience and thrive in a collaborative, low‑ego environment.

This is a very early team. You’re not joining an existing culture - you’ll be helping define it. We value agentic people who take initiative, push ideas forward, and shape the future rather than wait for direction.

We carve out plenty of time for heads‑down building while tackling meaningful problems. We value strong opinions, open discussion, and the humility to change direction when needed.

We focus on the sweet spot between what excites you and what moves the company forward. Here, you’ll own projects, ship features, and grow quickly alongside a team that’s redefining what authentication can be.

Required Skills:

• 5+ years of software development experience
• Strong TypeScript expertise (bonus points if you’ve wrestled with complex generics)
• Familiarity with different auth‑related specs and concepts
• Experience taking features from 0→1—shipping is second nature to you

Bonus Points:

• Experience maintaining open‑source projects
• Experience architecting or building complex auth systems

Company benefits:
Compensation: $140k–$180k USD based on experience (with very generous equity)
Fully remote: anywhere in the world (preference for USA or nearby time zones)
Early‑stage ownership in a high‑growth company

We build Better Auth almost entirely in TypeScript, and we push it to its limits. We work with advanced TypeScript generics and type inference to create APIs that feel effortless to use while being extremely type‑safe under the hood.

We’re open source, every line of code we ship to production is something we’re proud to share publicly. Our community depends on us to deliver clean, well‑architected, extensible code that others can learn from and contribute to.

Beyond the framework, we’re building a commercial infrastructure layer that still in TypeScript designed to solve hard, distributed‑systems problems:

• Analytics and user management dashboards

• Global session storage

• Bot/fraud/abuse detection at scale

• Transactional email/SMS pipelines
