Description

Leidos is seeking a Software Developer for a 200+ FTE technical development program supporting the Sponsor’s Entitlement Programs as well as IdAM /ICAM, Authentication, Authorization, Entitlements and Digital Policy Management. The Software Developer will work with a large team of developers and cloud engineers.

Primary Responsibilities:

The Developer will be part of a team of developers and cloud engineers that create new features for legacy applications as sponsor’s mission continues to expand and evolve. Our team also builds new applications as new mission needs arise. 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.

Required Qualifications

  • Active TS/SCI with Polygraph
  • BS degree 8+ years of relevant experience. Additional experience in lieu of degree.
  • Experience creating applications with Java, Springboot, and Amazon Web Services
  • Experience writing custom scripts to install and configure code in EC2 instances
  • Experience using Git, Jenkins, and Rundeck
  • Experience using CloudFormation scripts
  • Experience creating RESTful API
  • Experience working on a team that used the Scrum agile framework
  • Experience manipulating data using XML, JSON and YAML formats

Desired Qualifications

  • Certification - Amazon Web Services (AWS)
  • Experience delivering containerized applications with services similar to Docker and Kubernetes
  • Experience creating applications/services using Python
  • Experience with Elasticsearch and/or Kibana
  • Experience creating applications that rely on tokenization
  • Experience writing custom scripts to install and configure code in EC2 instances
  • Understanding of Identity Access Management (IAM) and Zero Trust concepts
  • Understanding of Artificial Intelligence (AI) concepts such as prompt engineering and large language models (LLM)
  • Experience building microservices
  • Experience with automated testing frameworks such as Katalon Studio or Selenium
  • Experience building solutions designed to continue operation even if one AWS region is unavailable

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo — because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.
