We’ve partnered with a well-backed Series B crypto startup building a secure, scalable backend platform that enables developers to create wallets and power cryptographic transactions with ease. Their product abstracts away complexity so teams can focus on building great user experiences while safely onboarding users and institutions onto the blockchain.

The platform is already used by companies like Alchemy, Dynamic, and Mural to support reliable, secure onboarding flows.

What you’ll work on

1. Build and scale backend services and APIs that power wallet creation, transaction workflows, and authentication
2. Design systems that prioritize security, reliability, and developer experience
3. Collaborate closely with product and frontend to support seamless onboarding flows
4. Own backend features end to end, from design to production

Company highlights

1. $52.5M raised (Series B)
2. HQ: New York City
3. Team: 27 engineers and builders
4. Location: Fully remote

Compensation: Base salary up to $275K + meaningful equity

This role is ideal for backend engineers who enjoy building product-driven systems, care deeply about correctness and scale, and want to work on crypto without living deep in protocols or infra.
