Leidos is seeking a Software Developer for a 200+ FTE technical development program supporting the Sponsor's Enterprise PKI System as well as IdAM IICAM, Authentication, Authorization, Attributes and Digital Policy Management. The Software Engineer will work with a team of developers, engineers and testers to support and modernize existing PKI systems as well as developing new systems for other networks.

Some after-hours or weekend work may be required to accommodate system deployments and upgrades. The Candidate must have a strong working knowledge of Public Key Infrastructure (PKI) and understand key concepts like digital certificates and Certificate Authorities (CAs). It is highly desired the Candidate also have knowledge of Registration Authorities (RAs), key management practices, cryptographic algorithms, certificate revocation procedures, and trust models.

The Developer will be part of a team of developers and cloud engineers that create new features for legacy PKI systems as sponsor's mission continues to expand and evolve.

Our work rhythm revolves around the Scrum agile framework to deliver incremental enhancements on a 3-week cycle. Developers actively participate in planning deliverables and grooming the Jira backlog. We rely on team collaboration to continually fine tune performance and ensure clear communication. Developers also participate in a team rotation of O&M responsibilities. They are required to be on-call for after-hours support approximately one week every three months.
