About the Role:
We’re seeking a Senior Combat Coder — a highly skilled, adaptable full stack developer who thrives in challenging, disconnected, and resource constrained environments. You’ll be building and integrating mission critical systems using Python, Apache NiFi, and other modern tools, often without the luxury of constant connectivity. This is not a “sit behind a desk and push commits” role — it’s for someone who loves solving hard problems in the field, under pressure, and with creativity.
Why You’ll Love This Role:
- You’ll work on high impact projects where your code directly supports critical missions.
- You’ll be part of a tight knit, elite engineering team that values skill, creativity, and adaptability.
- You’ll face real technical challenges that push your abilities far beyond the ordinary
Primary Responsibilities:
- Integrate systems and data flows using Python, NiFi, and other integration frameworks.
- Engineer resilient solutions that can operate in austere, bandwidth limited, or air gapped conditions.
- Collaborate with cross functional teams to rapidly prototype and deliver mission critical capabilities.
- Troubleshoot and optimize code and workflows in real time, often with incomplete information.
- Document and harden solutions for long term maintainability in the field.
Basic Qualifications:
- Bachelors Degree with 12+ years of experience or a Masters Degree with 10+ years of experience. Additional experience maybe considered in lieu of a degree.
- US Citizen with at least an active TS/SCI clearance and the ability to maintain your clearance during your employment with Leidos.
- Proven full stack development experience.
- Strong Python skills and experience with Apache NiFi or similar dataflow/integration tools.
- Comfort working in disconnected or degraded network environments — you know how to make things work without cloud dependencies.
- Solid understanding of APIs, data pipelines, and system integration patterns.
- Creative problem solver who thrives on tackling complex, ambiguous challenges.
- Self starter who can operate independently and deliver under tight deadlines.
- Strong interpersonal and communication skills.
- Understanding of source control such as Gitlab and others
Preferred Qualifications:
- Experience using JEMA and ARC GIS
- Experience with DevOps in air gapped environments.
- Background in secure coding practices and cyber resilient architectures.
- Prior work in mission critical, defense, or field operations.
