• Participate in technical design discussions, code reviews, and software development planning activities.
• Identify, troubleshoot, and resolve software defects and operational issues using logging and observability tools.

To be successful in this role you need the following (required qualifications):

• BS in Engineering, Computer Science, Systems Engineering, or related field and 4 or more years of prior relevant experience or Masters with 2 or more years of prior relevant experience.
• To be considered, must have an active Top Secret with SCI eligibility and ability to obtain and maintain a TS/SCI with Polygraph.
• Experience developing software applications using Python
• Experience with containerization technologies
• Experience developing and troubleshooting software in a Linux environment
• Experience using Git and collaborative software development workflows
• Strong verbal and written communication skills
• Experience working in an Agile software development environment
• Ability to work independently on assigned development tasks while collaborating effectively with a cross-functional team

You will wow us even more if you have some of these skills:

• Familiarity with DGX systems
• Elasticsearch certifications or other relevant technology stack certifications
• Experience supporting production or enterprise-scale software systems
• Familiarity with or experience developing applications that leverage Large Language Models (LLMs) or Agentic AI
