About F9

F9 is a mission-oriented team of Principal Software Engineers that have come together to deliver modern software engineering capabilities to the United States Defense Industry. Our customers include the United States Air Force, Aerospace, Raytheon, and Harris.

F9’s CEO, Eric Schoonover, started his career as a software engineer at Microsoft and Netflix where he progressed from a risky hire with no experience and no education to a principal level software engineer. He co-founded a YCombinator-funded startup after leaving Netflix and eventually landed at Time Inc as Vice President of Engineering. Prior to founding F9, he was Director of Engineering for the United States Digital Service in the Executive Office of the President, and Director of Engineering at the Defense Digital Service in the Office of the Secretary of Defense.

All F9 principals have extensive private sector experience and deeply value a culture of effective software engineering, freedom, and responsibility.

About Kessel Run

F9 holds a multi-year contract with the Air Force contributing to the Kessel Run software development program. Kessel Run has changed how the Department of Defense organizes, codes, builds, deploys, and operates software in support of American warfighters.

The Kessel Run Engineering Services (KRES) team is based out of the Kessel Run Experimentation Lab (KREL), an entire floor of the WeWork office in downtown Boston. KRES is responsible for developing and operating a suite of shared services that deliver economies of scale to the software engineering teams addressing a wide variety of Air Force missions.

The KRES team develops and operates engineering, security, release, deployment, health & monitoring, runtime, identity, and a variety of storage services. Each of these services is leveraged by dozens of mission teams and hundreds of software engineers.


As a Software Engineer on the Kessel Run Identity team you will be responsible for the development, delivery, and operations of the software systems that enable war fighters self-service identity registration and administration. Think Google Sign-In for the Air Force.

The Kessel Run Identity Service implements the OAuth2 standard and is used by all Kessel Run mission applications to enable Single Sign-On. You will also be responsible for the reliable operations of the Kessel Run Identity services across all Kessel Run environments, unclassified and classified.

As the scope of work for the Kessel Run identity team expands additional capabilities need to be designed and delivered to support additional forms of multi-factor authentication, authorization and role based access controls, and shared user profiles.

Required Capabilities

This is a individual contributor position, the expectation is that you are an effective software engineer capable of delivering highly reliable software that meets mission requirements. You collaborate well with more experienced software engineers learning from them and leveraging thoughtful peer review and pairing to continuously improve your own work output. You have demonstrated hands-on experience implementing RESTful web services using Java and SpringBoot or demonstrated hands-on experience implementing web applications using Facebook’s React. You are comfortable deploying and operating applications using commercial cloud services.
