Web3 verification layer

Senior 150-200k base + bonus Remote engineering

About Our Client

Our client is building the foundational human verification layer for the AI era. Their privacy-preserving, decentralized identity network enables individuals to prove uniqueness while keeping full control of their data. The platform combines biometric verification, zero knowledge cryptography, and blockchain infrastructure and already serves millions of users.

The mission is to create a trusted digital ecosystem where people can own their identity and interact securely across applications and environments.

The Opportunity

We are hiring a senior technical leader to own the entire Developer Platform. This role shapes how thousands of developers integrate identity, verification, and privacy tooling. You will architect APIs, SDKs, and infrastructure that make secure human verification simple for developers across consumer apps, AI products, Web3, and enterprise environments.

Ideal for a platform engineer who enjoys deep technical ownership, product thinking, and architecting systems at scale.

What You Will Do

  • Design and scale the core Developer Platform across API gateways, authentication, SDKs, and partner tooling.

  • Architect and deploy identity infrastructure using OAuth2, OIDC, PKCE, API key management, and global rate limiting.

  • Lead development of Verifiable Credentials APIs for issuing and verifying W3C-compliant credentials with ZK privacy.

  • Own the end-to-end developer experience from portal to sandbox, documentation, workflows, and developer onboarding.

  • Define public API standards, versioning strategy, error handling, and client libraries for TypeScript, Python, and Go.

  • Work with Platform Engineering on global API delivery, observability, security, and disaster recovery.

  • Mentor platform engineers and provide architectural leadership.

  • Translate partner requirements into scalable capabilities across Web3, DeFi, consumer, and enterprise identity.

  • Uphold best practices in testing, security, performance, and reliability.

  • Shape the roadmap for new primitives such as eventing, analytics, and next-generation zero knowledge identity features.

What You Bring

  • 8+ years in backend or platform engineering with strong experience building and scaling public APIs.

  • Deep knowledge of identity and access management, including OAuth2, OIDC, PKCE, and JWT.

  • Strong API design skills with clear thinking on developer experience, lifecycle, and backward compatibility.

  • Experience creating SDKs and developer tools across multiple languages.

  • Production experience in resilient multi-region systems with observability, traffic management, and fault tolerance.

  • Proficiency with TypeScript and modern backend frameworks.

  • Security-first engineering mindset.

  • Strong communication and leadership skills.

You Will Thrive If

  • You operate with high agency and clear ownership.

  • You write strong technical documentation, RFCs, and architecture proposals.

  • You have experience scaling platforms through rapid growth.

  • You care deeply about developer experience and usability.
