Your Role

As the founding Engineering Lead for the Polygon Fintech Labs team, you’ll own the technical vision for our application layer's suite of products.

• Define engineering best practices that balance performance, modularity, and compliance readiness

• Translate product milestones into technical roadmaps and development sprints

• Collaborate tightly with product and design to turn financial UX into robust, scalable code

• Hire and mentor early engineers, setting the technical culture for a lean but high-caliber team

What You’ll Need

• 6+ years of experience developing production applications, preferably in fintech or crypto domains

• Proven React Native expertise, with the ability to own end-to-end mobile architecture

• Experience building API-integrated apps or financial interfaces such as wallets or programmable money flows

• Familiarity with KYC/AML processes, payments, FX, or yield-generating protocols

• Track record of launching early-stage products from 0→1 in fast-paced environments
