Job description

We’re building a new infrastructure layer focused on verification, attribution, and long-lived trust.

It’s not a marketplace, not a job board, and not token-driven. The goal is to replace brittle intermediaries with durable, auditable signals that real companies rely on.

This is a founding engineering role with real ownership and architectural influence.

What you’ll work on

• Design and implement event-driven verification systems
• Build append-only audit trails and attribution flows
• Model identity, relationships, and outcomes over time
• Own early architectural decisions and system boundaries

How we think about tech

• Architecture is event-driven and verification-first
• Stack is intentionally open the founding engineer helps choose tools based on correctness, simplicity, and longevity
• Boring, proven technology over novelty
• Off-chain first; crypto later if and where it makes sense

Who this is for

• Senior engineers who’ve built fintech, payments, identity, compliance, or trust-heavy systems
• Builders who care about correctness more than flash
• People who enjoy ambiguity, ownership, and first-principles thinking

This is not

• A DAO
• A feature factory role

Seniority level

• Mid-Senior level
