About the Role

ID.me is seeking a Principal Software Development Engineer to serve as the technical authority across the Person and Trust platforms — the systems that define who a person is and how much confidence ID.me can place in that identity. You will own the data model strategy, API contracts, and long-term architecture across the Person API, the Trust Service, and the Inspection Catalog, along with the verification and validation evidence that connects them.

Person, Trust, and the Inspection Catalog are foundational systems at ID.me: together they determine who someone is, how inspection evidence is collected, and how much confidence to place in that identity. The role calls for deep expertise in data modeling and graph structures, applied to how verification and validation evidence and the resulting trust decisions are represented and queried. You will own how identity data is modeled — including how Person-to-SSN, Person-to-Face, and Person-to-Legal relationships are expressed — and how confidence in an identity is determined.

You’ll set technical direction, establish the patterns and contracts that other teams build against, and partner closely with Product, Architecture, Identity, Security, and Compliance to deliver a trustworthy foundation used by millions of users and trusted partners.

Key Responsibilities

• Own the data model strategy and long-term architecture across the Person API, Trust Service, and Inspection Catalog, keeping all three as the authoritative source of truth for identity, evidence, and confidence.
• Own the API contracts across the domain, including versioning, compatibility, and governance standards that internal and external consumers depend on.
• Set technical direction and design standards for the domain.
• Mentor staff and senior engineers, raising the bar for data modeling, API design, and trust architecture across the organization — and filling the domain leadership gap with intentional, lasting technical ownership.
• Lead the modernization and consolidation of legacy identity data into a scalable, modular set of services and contracts.
• Ensure the security, privacy, and compliance of Person, Trust, and Inspection Catalog data.

Required Qualifications

• 10+ years of software engineering experience, including significant time as a recognized technical authority for a complex domain spanning multiple systems.
• Deep expertise in data modeling and graph data structures, including designing schemas and relationships that remain correct, performant, and auditable at scale.
• Proven track record designing and owning APIs and data contracts for source-of-truth systems used by internal and external consumers.
• Demonstrated ability to set technical strategy and drive alignment across engineering teams without direct authority.
• Bachelor’s degree in Computer Science or equivalent experience.

Preferred Qualifications

Especially important for this role:

• Hands-on experience with graph databases and the modeling tradeoffs between graph and relational representations of connected identity data — this is central to how we represent Person-to-SSN, Person-to-Face, and Person-to-Legal relationships.
• Experience modeling evidence and confidence scoring into a coherent, queryable record — specifically connecting inspection evidence from the Inspection Catalog to trust decisions in the Trust Service.

Also valuable:

• Experience building or owning systems that model, store, and maintain person or entity attributes and relationships at scale.
• Expertise in NIST 800-63 IAL2/AAL2 standards, including evidence requirements, verification methods, and identity lifecycle management.
• Experience with cloud-native infrastructure (GCP, AWS, or Azure).
• Experience operating in regulated environments (security, compliance, or data privacy requirements).
• Familiarity with emerging identity and credentialing standards (e.g., Verifiable Credentials, Decentralized Identifiers, OIDC extensions).
• Excellent communication skills and a track record of influencing technical direction across an organization.
