Nice to Have * Demonstrated expertise in building and operating public-facing REST or GraphQL APIs at scale. * Deep experience with relational databases (e.g., PostgreSQL) and NoSQL or graph data stores. * Solid understanding of distributed systems concepts, caching, asynchronous processing, and cloud-native patterns. * Experience implementing authentication and authorization (OAuth2, OIDC, JWT, or custom schemes). * Experience with cloud infrastructure (AWS, GCP, or Azure), including containerization (Docker, Kubernetes, or Nomad) and deployment pipelines. * Proficiency with AI-assisted development tools (e.g., GitHub Copilot, Cursor) to accelerate delivery and code quality. * Exposure to A/B testing strategies and ability to interpret results. * Knowledge of event-driven architectures (Kafka, SNS/SQS) and patterns for decoupled service communication. * Exposure to digital credential and identity standards (e.g., Verifiable Credentials, Decentralized Identifiers, W3C DID specs). * Familiarity with identity and credential verification systems, including data validation, proofing, or trust scoring. * Experience in regulated or high-assurance domains (government, financial, or healthcare systems) is advantageous. * Experience working with Ruby on Rails. * Startup experience. ## Description ID.me is seeking a Staff Software Development Engineer to join the Biometrics and Credential team. This team is building the identity graph that represents mappings between entities, attributes, and credentials. Analysis of entity-attribute relationships will lead to an improved understanding of customers, reduce friction in identity workflows, and enable key use cases like fraud detection and prevention, duplicate detection and resolution, and more. As a key individual contributor, you'll architect and implement the services that underpin ID.me's next-generation identity trust layer. You'll work across identity, verification, and platform teams to deliver a secure, scalable, and high-performance graph platform used by millions of users and trusted partners. You will have a significant opportunity to shape the roadmap and direction of this initiative through your innovative ideas and technical expertise. This position is based full-time in our Mountain View, CA office, with on-site presence required 5 days per week. What You'll Do * Design and implement core services and APIs that power the Identity Trust Graph - representing mappings between entities, attributes, and credentials. * Build RESTful and GraphQL endpoints that meet strict standards for reliability, latency, and security, and integrate seamlessly with both internal and external systems. * Develop robust data models and storage patterns to represent credential provenance and entity-attribute relationships across relational and graph databases (including Neo4j). * Implement graph lifecycle flows - including ingestion, validation, and enrichment - integrated with ID.me's identity verification and attribute validation systems. * Ensure the security and privacy of identity data through strong authentication, authorization, encryption, and audit practices. * Consistently ship features and improvements, collaborating with the team on larger projects. Effectively switch gears between maintaining legacy code and writing modern services. * Collaborate with team members, product managers, and stakeholders to solve the right problems and build the best solutions for customer needs. * Act as a mentor to junior developers through code reviews, document critiques, and cross-team knowledge sharing forums. * Write high-quality, maintainable, and well-tested code, including automated tests and observability instrumentation. * Contribute to system design discussions, code reviews, and technical documentation to drive clarity and alignment across teams. * Continuously optimize performance, scalability, and reliability of graph services in production environments. * Stay current on emerging identity and credentialing standards (e.g., Verifiable Credentials, Decentralized Identifiers, OIDC extensions) and bring new ideas into the product.
