Job description

Description

Do you enjoy solving challenging problems and want hands-on experience with cloud-native technologies, DevSecOps, and distributed systems?

Are you eager to learn from experienced engineers while contributing to secure, reliable software with real-world mission impact?

If so, we're looking for someone like you to join our team at APL!

We are looking for an Associate Software Engineer to help design, develop, and maintain critical software that supports National Security Space operations in a TS/SCI environment. You will work on scalable, secure, and observable systems for spacedomain applications such as commandandcontrol, data processing, mission planning, and multidomain integration tools. This is an excellent opportunity to grow your engineering skills while contributing to some of the toughest problems faced by our sponsors.

The role emphasizes DevSecOps practices, cloudnative architectures, and secure development/deployment in classified environments. You will work on distributed systems where reliability, security, performance, and auditability are essential, and you will receive mentorship from senior engineers throughout the process.

As a Junior Software Engineer you will...

• Assist in designing and implementing backend services, APIs, and data pipelines for spaceoperations software.
• Help build and maintain containerized applications and contribute to CI/CD pipelines under guidance.
• Participate in adding security controls throughout the development lifecycle (DevSecOps).
• Support development of eventdriven or messagingbased components (e.g., basic Kafka/RabbitMQ usage).
• Follow compliance procedures for classified environments, including airgapped deployments and controlled updates.
• Identify and solve issue, monitor, and improve system performance and observability in test and staging environments.
• Participate in code reviews, learn from architecture discussions, and receive mentorship on standard methodologies.

Qualifications

You meet our minimum qualifications for the job if you...

• Hold a Bachelor's degree in Computer Science, Software Engineering, a related field, or equivalent practical experience (internships, opensource contributions, capstone projects).
