Job Description

Join NAVI Labs as a Fullstack Engineer to build the financial infrastructure layer of the Sui blockchain.

This is a high-impact role in a fast-scaling team where you'll bridge React frontends with high-performance Node.js backends.

Location

San Francisco, USA

Why this role is remarkable

• Massive existing traction with $400M+ TVL and 900,000 users on Sui, positioning you at the center of one of the fastest-growing DeFi ecosystems.
• True greenfield opportunity building new product lines from scratch rather than maintaining legacy code, working directly on lending, liquid staking, and automated vaults.
• Backed by tier-1 crypto investors including OKX Ventures, Hashed, and dao5, offering the stability of a proven protocol with the growth upside of an early-stage team.
  
  

What You Will Do

• Design and develop end-to-end web applications, integrating React frontends with Node.js backends and complex blockchain smart contracts.
• Collaborate with product and design teams to architect and launch new DeFi products like automated vaults and liquid staking tools.
• Optimize application performance and scalability to handle high-demand transaction volume and secure real-money financial operations at scale.
  
  

The ideal candidate

• 3+ years of professional fullstack experience, demonstrating deep proficiency in React, Node.js, and building rigorous, scalable web architectures.
• Proven ability to ship fast in a startup environment, with a "builder" mindset capable of taking features from concept to production.
• Strong computer science fundamentals; while deep crypto experience is a plus, we value sharp Web2 engineers eager to master blockchain integration.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
