The Role
As a Software Engineer, you will design and develop scalable systems, write clean code, deploy applications to cloud environments, and ensure quality through testing, collaborating with teams, and improving user experience.
Summary Generated by Built In
Leidos is seeking Software Engineers to support the Catena project. In this hands-on position, you will work collaboratively to architect, design, build, deliver, and enhance highly available, scalable systems using modern technologies. You will play a key role in shaping the future of our front-end and back-end architecture, ensuring seamless deployment within an AWS environment using Serverless frameworks and GitLab CI pipelines.

This role is 100% remote but proximity to the Washington Metro Area is preferred.

This posting is for multiple opportunities ranging in years of experience. Level of opportunity, including compensation, will be matched to a candidate’s experience.

Primary Responsibilities:

  • Design, develop, and maintain scalable and efficient front-end and back-end systems using modern programming languages and frameworks.
  • Write clean, maintainable, and well-documented code following best practices and coding standards.
  • Develop and maintain APIs, microservices, and server-side logic using languages like Java, Python, Node.js, or similar.
  • Deploy applications to cloud environments (e.g., AWS, Azure, Google Cloud) and ensure scalability and reliability.
  • Implement database solutions, including schema design, queries, and optimization for relational (e.g., PostgreSQL, MySQL) or non-relational (e.g., MongoDB, DynamoDB) databases.
  • Write unit, integration, and end-to-end tests to ensure code quality and functionality.
  • Collaborate with QA teams to identify and resolve bugs and performance bottlenecks.
  • Conduct peer code reviews to ensure quality, consistency, and adherence to best practices.
  • Provide constructive feedback to team members and incorporate feedback into your own work.
  • Debug and resolve technical issues across the stack, ensuring minimal downtime and optimal performance.
  • Identify and implement solutions to improve system reliability and user experience.
  • Communicate with internal team members across multiple areas and client team members.

Basic Qualifications:

  • US Citizenship; Ability to obtain a DoD Secret security clearance.
  • Bachelor's degree with under 2 year or 2+ years of experience. Equivalent professional experience may substitute for a degree. An advanced degree may offset some experience requirements.
  • Experience developing software systems using Java or Python.
  • Front-end development using React and Typescript.
  • Experience with Infrastructure as code tools like Terraform.
  • Experience developing and deploying software into cloud environments, particularly AWS.
  • Experience working in a DevOps environment with a CI/CD pipeline.
  • Experience with serverless frameworks for building scalable applications.
  • Strong verbal and written communication skills and the ability to interact at multiple levels of the organization.
  • Understanding of GitLab CI/CD, with experience in creating pipelines for automated testing, deployment, and monitoring.

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.

Original Posting:October 15, 2025

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Pay Range:Pay Range $55,250.00 - $99,875.00

The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.
