Why Leidos? You'll work on systems where performance, precision, and reliability matter - every second. This is not experimental AI for prototypes. This is disciplined, responsible AI applied to mission-critical software that supports national infrastructure. If you're excited by solving complex problems in regulated, real-world environments - and using AI as a force multiplier rather than a shortcut - we'd like to talk. ## Description Leidos is seeking an ICAM / Identity Engineer to join the Air Traffic Business Area within the Homeland Sector, supporting the development of the Leidos Common Automation Platform (L-CAP). L-CAP is a mission-critical, future-ready automation platform built on a hybrid cloud data mesh architecture, enabling next-generation air traffic management capabilities. We are building with an AI-first engineering mindset, embracing emerging AI capabilities and modern development practices to accelerate delivery, improve software quality, and continuously evolve how we design and build mission-critical systems. This role operates within a SAFe/Agile framework as part of an Agile Release Train (ART) delivering iterative value across the program. This position supports government programs and requires the ability to obtain and maintain a favorable Public Trust investigation. This is a hybrid position requiring 3 days onsite and 2 days working from home, if you are located within a commutable distance (Less than 1 hour's drive one-way during normal traffic) from Gaithersburg, MD; Eagan, MN; or Egg Harbor Township, NJ. However, if you do not reside within a commutable distance, you may be considered for a 100% remote role. In this role, you will implement the identity, credential, and access management (ICAM) layer that governs every user and service interaction with L-CAP. You will integrate the platform with government-provided ICAM services, enforce per-session authorization across distributed mission services, and build the access control and audit foundations that operational and support users depend on. What You'll Do: * Integrate L-CAP services with government-provided ICAM services using OAuth 2.0 and OpenID Connect, including token issuance, validation, and claims mapping. * Implement and maintain identity federation and user stores (Keycloak or equivalent), including role-based test account provisioning. * Implement per-session authentication and authorization for user-to-service and service-to-service requests, enforcing default-deny access regardless of network location. * Implement mutual TLS (mTLS), service mesh/workload identity, and certificate lifecycle management, including issuance, rotation, expiration monitoring, and revocation. * Design and implement role-based (RBAC) and attribute-based (ABAC) access controls aligned to operational and support roles. * Implement authentication and session management for operational users, including sign-in/sign-out and time-on-position logging. * Implement authentication and authorization audit logging, including event capture, storage, and retrieval. * Implement API gateway authorization and ensure external-facing endpoints are registered and protected through the API management layer. * Support security authorization and continuous monitoring by producing ICAM control evidence, resolving identity integration issues across distributed services, and leveraging AI-assisted development and automation to improve quality and delivery. ## Related Videos - [Rate-limiting using eBPF and Istio: How to protect your SaaS customers from themselves](https://www.wearedevelopers.com/videos/100220-rate-limiting-using-ebpf-and-istio-how-to-protect-your-saas-customers-from-themselves) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Automated Security for the Entire SDLC](https://www.wearedevelopers.com/videos/100323-automated-security-for-the-entire-sdlc) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix)
