Role Overview:

ID.me is transitioning to a platform-first approach, building scalable APIs and data-driven services that power our eCommerce marketplace, developer ecosystem, and partner integrations. As a Software Development Engineer VI on the Marketplaces Platform team, you will play a key role in designing and maintaining high-performance private and public APIs that drive revenue, support merchants, and protect users from fraud.

This team will decompose the monolithic ID.me Shop into modular, service-oriented APIs, enabling faster innovation, improved developer experience, and seamless partner integrations. Our goal is to set a new standard for API quality, documentation, and service interfaces, ensuring clear contextual boundaries across teams for independent development and better communication.

This role is ideal for an API-first engineer who thrives on platform thinking—building data products without a UI that empower products and external developers.

Key Responsibilities:

Design, build, and maintain API-first services for ID.me’s Marketplaces Platform, supporting eCommerce merchants, government services, and fraud prevention.
Lead the decomposition of the ID.me Shop monolith into scalable, modular APIs, improving system flexibility and maintainability.
Establish best-in-class API standards—clear versioning, intuitive service interfaces, robust documentation, and developer-friendly tooling.
Develop APIs for offers, attribution tracking, paid placements, scam/fraud prevention, and Shop analytics, ensuring scalability and performance.
Collaborate with internal teams and external partners to create seamless API experiences that drive adoption and engagement.
Raise the bar on API design—implement authentication, versioning, rate limiting, and encryption best practices.
Optimize query performance and data flows, ensuring API efficiency when interacting with stores, marketplaces, and government services.
Mentor engineers and contribute to establishing engineering excellence, reinforcing platform-first thinking across teams.

Required Qualifications:

Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
12+ years of software development experience with SaaS platforms and APIs.
Expertise in RESTful API design, GraphQL, and microservices architecture.
Strong proficiency in Ruby, Java, Go, Python, or JavaScript (Node.js) for backend development.
Experience with platform-first architectures, enabling multiple teams to build on shared API-driven foundations.
Deep understanding of API security best practices (OAuth, JWT, encryption, vendor authentication).
Hands-on experience with cloud platforms (AWS, GCP, or Azure) and distributed systems.
Experience working with databases (SQL and NoSQL), caching, and event-driven systems (Kafka, RabbitMQ, SQS).
Strong problem-solving skills, with a focus on observability, reliability, and API performance.

Preferred Qualifications:

Experience with developer-first products, creating intuitive API documentation, SDKs, and sandbox environments.
Proven track record in breaking down monolithic applications into microservices or API-first architectures.
Familiarity with eCommerce integrations, paid placements, and attribution tracking.
Prior experience working with vendor integrations and optimizing service interfaces.
Passion for improving developer experience, including automation, API governance, and CI/CD.
