About this role
Summary / Objective
Identity Digital Innovation Labs (IDIL) is building DNSid, the foundational identity layer for the agentic internet, enabling AI agents to establish verifiable, DNS-anchored identities. This principal-level software engineering role will build the platform, SDKs, and tooling that make DNSid real, while bringing deep, hands-on security expertise to every layer of the product and engineering organization. Security is not a feature of DNSid; it is the product, and this engineer will write and review production code, shape the cryptographic core, define the standards the team builds against, and own the security posture of the IDIL engineering org.
This role reports to the VP, Engineering & Technical Architect.
What You'll Do
- Own the security architecture and threat model for the DNSid platform, SDKs, and supporting infrastructure (STRIDE analysis, attack surface review, trust boundaries)
- Design and review the cryptographic core: signing, verification, key management, rotation, and revocation
- Build and maintain the DNSid SDKs (TypeScript, Go, and Python) with security-first design and safe defaults
- Define and enforce supply-chain security practices for the codebase and dependencies
- Conduct security reviews of new features, integrations, and partner-facing implementations
- Partner with the standards effort (IETF draft) so the security properties are sound and keep the implementation honest
- Establish secure-by-default patterns for how third parties integrate DNSid (auth schemes, scope validation, token handling)
- Own the security posture of the entire IDIL engineering org: secure deployment patterns, secrets management, audit readiness (SOC 2), and incident response
- Actively models and promotes Identity Digital’s core values through day-to-day interactions, behaviors, and decision-making
- Other duties as assigned
