Job Description

Junior AI Software Engineer | Egg Harbor Township, NJ or Gaithersburg, MD or Eagan, MN | Hybrid | $69,550 - $125,725

We're working with a global leader in mission-critical digital transformation and aerospace innovation on this exciting opportunity.

This isn't your average dev role; you'll be building real-time, safety-critical systems for the UK National Airspace using C++, Ada, and cutting-edge AI-augmented development workflows. We are looking for a forward-thinking engineer who doesn't just code, but leverages LLMs like Claude and GitHub Copilot to outpace the status quo in high-availability environments.

The Role

  • Design and maintain high-availability software for national air traffic management systems utilizing C, C++, and Ada.
  • Lead the charge in AI-driven engineering by integrating Claude Code and GitHub Copilot into the full SDLC for code generation and refactoring.
  • Develop automated test frameworks and debugging scripts to ensure the reliability of massive, real-time multi-threaded systems.
  • Architect low-level communication protocols including TCP/IP, UDP, and SCTP within Linux Red Hat and virtualized environments.
  • Collaborate with cross-functional teams to modernize safety-critical infrastructure with a human-in-the-loop AI approach.

What You'll Need

  • 4-8 years of software engineering experience (or a Master’s with 2-6 years) with a strong background in Object-Oriented Programming.
  • Proven expertise in C++ or C; experience with Ada is a major plus for these mission-critical systems.
  • Hands-on proficiency with AI-assisted coding tools and LLM platforms like OpenAI, Anthropic, or Google Gemini.
  • Solid experience with Linux, hypervisors, and real-time system integration for complex hardware environments.
  • US Citizenship and the ability to obtain a Public Trust clearance are required for this national infrastructure project.

What's On Offer

  • Highly competitive salary range ($69,550 - $125,725) based on experience and technical mastery.
  • Flexible hybrid work schedule (3 days onsite, 2 days remote) to balance high-stakes mission work with personal flexibility.
  • Opportunity to work on "Step 30" technology at a company that prioritizes disruption and rapid innovation over the status quo.
  • Comprehensive benefits package including Health/Wellness programs, retirement plans, and professional development support.
