Job description

Senior Software Engineer
We are seeking a Senior Software Engineer to enhance and modernize our control software for Remote Weapon Station (RWS) platforms. This role focuses on the evolution of Java-based software responsible for system logic, hardware integration, and command-and-control (C2) communications.
The successful candidate will be tasked with integrating next-generation sensor payloads into an established design while significantly expanding the system's remote capabilities. A key objective is to evolve our proprietary C2 protocol to allow for full "headless" operation-ensuring that all system functions currently managed via physical operator interfaces and local UIs can also be executed programmatically via external software interfaces.
Job Duties
The successful candidate will be tasked with integrating next-generation sensor payloads into an established design while significantly expanding the system's remote capabilities. A key objective is to evolve our proprietary C2 protocol to allow for full "headless" operation-ensuring that all system functions currently managed via physical operator interfaces and local UIs can also be executed programmatically via external software interfaces.
Key Responsibilities
  • System Integration: Modify existing Java software to support and interface with new hardware payloads and advanced sensor subsystems
  • Protocol Expansion: Lead the development and expansion of our proprietary C2 protocol to incorporate new command sets and telemetry data
  • Headless Control Development: Enhance software logic to support concurrent control paths, ensuring the platform can be operated via existing physical controls/UIs or through a fully remote, software-only (headless) interface.
  • Software Reliability: Maintain and update high-reliability code within a Linux-based environment, ensuring low-latency response times for critical system functions.

Required Qualifications
  • BA/BS in Software Engineering, Computer Engineering, or related field of study
  • 8+ years of applicable experience
  • Expert-level proficiency in Java, specifically for backend logic and systems-level applications
  • Proficient with C/C++ programming language

Preferred Qualifications
  • MA/MS in Software Engineering, Computer Engineering, or related field of study
  • Experience working with legacy codebases to add modern functionality without compromising existing stability
  • Proven experience enabling remote/API-based control for systems that traditionally rely on physical or graphical user interfaces
  • Strong command of socket programming (UDP/TCP) and serial communication (RS-232/422) for machine-to-machine interfacing
  • Working knowledge of embedded or real-time software development
  • Familiarity with hardware-in-the-loop (HIL) testing and troubleshooting complex integrated systems
  • Ability to work in team environment interacting with a variety of functional areas and management levels
