Job description

Description


The Junior Tactical Software Engineer supports the design, development, integration, and continuous improvement of internal systems, customer-facing applications, and experimental software and hardware-integrated platforms.
This role is hands-on and development-focused, working directly with senior engineers and system architects on multiple technical initiatives, including product development, system integration, field-deployable solutions, and defense-oriented tactical communication systems.

The position requires a balance of software engineering fundamentals, system-level thinking, and field execution, including participation in live demonstrations, operational testing, and DoD-related field evaluations.


Responsibilities

  • Full-Stack Development
  • Coding: Assist in building backend services, APIs, and internal systems.
  • Prototypes: Help build "Proof of Concept" projects and experimental tools.
  • Maintenance: Debug, test, and optimize existing platforms to keep them running smoothly.
2. Tactical Systems & Radio Integration
  • Hardware Bridge: Write code that allows software to "talk" to military radios using older protocols like RS-232C.
  • Data Routing: Handle how data moves between serial hardware and modern IP-based applications (like ATAK).
  • Troubleshooting: Work with senior engineers to fix bugs where the software meets the hardware.
3. Field Operations (10-20% Travel)
  • Live Testing: Travel to military facilities to set up, test, and analyze software during live field exercises.
  • Client Interaction: Give product demos, lead technical briefings, and train customers on how to use the systems.
  • Support: Provide on-site technical help during scheduled defense training events.
4. DevOps & Collaboration
  • Workflow: Support CI/CD pipelines, cloud integrations, and system monitoring.
  • Teamwork: Participate in code reviews and help translate field feedback into new software features.


Requirements


  •  Bachelor's degree in computer science, Software Engineering, Information Systems, or a related technical field, or equivalent practical experience.
  •  3 years foundation in modern software development and an interest in defense, tactical, or operational systems.
  • Comfortable with Git in an Agile team environment. 
  • Familiarity with frontend frameworks (React, Flutter, or similar), cloud services, and CI/CD pipelines is preferred.
  • Comfortable working in military or operational environments, following structured test procedures
  • Travel up to 20% annually for training events and field evaluations.

Preferred Qualifications:

  • Experience with modern frameworks such as React, Flutter, FastAPI, or similar
  • Understands REST APIs
  • Experience with API integrations and third-party services
  • Exposure to mobile application development
  • Experience in startup or small-team development environments
  • Exposure to defense, tactical systems, embedded systems, or radio-based communications is a strong plus
