Senior Software Engineer - Reporting and Billing

Location: McLean, Virginia

Department: Engineering

Role Overview

ID.me is seeking a Senior Software Engineer to join the Reporting & Billing team, where we build the definitive record for the member experience: every workflow, decision, step, and outcome a person moves through while proving who they are. Over 152 million members verify with ID.me across federal agencies, state governments, healthcare organizations, and consumer brands, and each of those journeys is a workflow. Documents get inspected, faces get matched, consent gets granted, sometimes on the first attempt, sometimes across several, sometimes not at all. We are building the system that models all of it consistently and cleanly, so that our customers can report on it, our analysts can study it, and our invoices can run on it.

As a Senior Software Engineer, you will be a key member of the team building this. With the team, you will own the reporting data model, design the delivery mechanisms (APIs, exports, event streams) that get the data into customers' hands, and help architect the automated billing system that runs on top of it. That billing architecture is ours as a team to define end to end. It is a rare scope that spans product-facing data platform work and revenue-critical financial systems, with the latitude to design both from the ground up.

This position will work from our McLean, VA office five days per week.

Key Responsibilities

• Build the Transactions Data Model: Build the customer facing data model to track user activity. 
• Build Customer Data Delivery: Design and build the mechanisms customers use to get their reporting data through the Developer Portal — query APIs, scheduled and on-demand exports, webhooks, and event streams. Own the API contracts and delivery SLAs that customers and their integrations depend on, including versioning, backwards compatibility, and deprecation.
• Develop Billing Automation: Implement the design of the metering and billing architecture that turns events into accurate, auditable charges.
• Reliability, Correctness & Compliance: Own the availability and correctness of reporting data writes, reads, and billing runs at production scale. Lead work on observability, data quality monitoring, reconciliation tooling, query performance, and incident response for systems where an error is either a customer-facing data defect or a revenue defect. Ensure the systems meet the security, privacy, and audit requirements of a NIST 800-63-3 AAL2/IAL2 credential service provider.
• AI-Augmented Development: Model and champion AI-first engineering practices — leveraging tools like Claude Code and Cursor to accelerate design, implementation, and review cycles — and help the broader team adopt these workflows effectively.

Basic Qualifications

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
• 6+ years of professional software development experience building and operating production web applications. [Less for PHD, Masters]
• 3+ years of experience building developer-facing platforms such as developer portals, API platforms, authentication platforms, cloud platforms, payments platforms, or other self-service developer experiences.
• 3+ years of experience with TypeScript, React, and modern frontend architecture, including production experience with Next.js or similar frameworks and operating backend services using modern web frameworks such as Ruby on Rails, Node.js, Java, or similar.
• Proficiency with AI-assisted development tooling (e.g., Claude Code, Cursor) and a commitment to an AI-first engineering culture that leverages these tools to improve software quality, testing, and engineering velocity.

Preferred Qualifications

• Hands-on experience with Salesforce, NetSuite, and Snowflake — particularly integrating them into an automated quote-to-cash or usage-to-invoice pipeline.
• Experience designing or operating a usage-based metering and a billing system. 
• Experience building customer-facing data delivery: reporting APIs, bulk export pipelines, or streaming event feeds and building the developer experience around them.
• Proven ability to own and evolve platform APIs consumed by multiple internal teams and external customers, across the full lifecycle from design through versioning and deprecation.
• Experience replacing a manual, spreadsheet-driven business process with an automated system.
• Experience with identity standards such as NIST 800-63-3, OAuth2, or OpenID Connect.
• Experience working in regulated industries such as government, healthcare, or financial services.
• Track record of improving engineering culture through documentation, technical standards, architectural review, and developer experience improvements.
• Experience defining, developing, and operating backend APIs using Java, Kotlin, Go, or similar. 
• Experience at scale designing and owning event driven architecture using technologies such as Kafka, Pub/Sub, SNS, Debezium, or similar.
