Role Overview
We are seeking a Software Engineer with 1-3 years of experience to support and troubleshoot mission-critical web applications in a secure, government environment. This role is ideal for an early-career engineer who is eager to learn, enjoys solving complex problems, and wants to be challenged in a collaborative, fast-paced technical setting.
In this role, you will work alongside experienced engineers to support production web applications, investigate application issues, assist with root-cause analysis, and help automate solutions that improve system reliability and performance.

Key Responsibilities
- Support and troubleshoot production web applications in a secure environment
- Assist with incident response, issue triage, and root-cause analysis
- Analyze logs, metrics, and application behavior to identify and resolve issues
- Use Python-based scripting and Ansible automation to reduce manual effort and improve system stability
- Collaborate with software, platform, and systems engineers to implement fixes and enhancements
- Participate in continuous improvement efforts related to reliability, performance, and automation
- Document troubleshooting steps, resolutions, and lessons learned
Required Qualifications
- Active DoD Secret clearance
- Bachelor's degree in Computer Science, Engineering, or a related technical field (or equivalent experience)
- 1–3 years of experience in a software, systems, or application support role
- Experience troubleshooting web applications or software-based systems
- Hands-on experience with Python (scripting or development)
- Exposure to Ansible or similar automation/configuration tools
- Strong problem-solving and debugging skills
- Ability to work in a classified environment and follow security requirements
