Job description

Senior Software Developer

OASYS, INC., a Leading-Edge Government contractor in Huntsville Alabama, is seeking a Senior Software Developer to support our ARMY/MDA customer onsite at Redstone Arsenal, Huntsville, AL.

Job Responsibilities include: You will help drive the technical evolution of mission-critical warfighter training and planning tools. This Java based tool provides warfighters and sensor managers with the ability to rapidly plan, optimize, and deploy layered sensor search plans in operational timelines. Your knowledge and skills will directly enhance the survivability and battlespace awareness of fielded assets, integrating high-fidelity intelligence data, complex physics-based models, and tactical hardware health into a streamlined operational tool.

  • Support the software design for the core man-in-the-loop graphical user interface, the Rapid Response Tool (RRT), and the Socrates parsing utility.
  • Design and maintain seamless interoperability with external intelligence and modeling frameworks, specifically the Threat Generation External (TGx) and the Threat Modeling Center (TMC) Threat Modeling & Simulation Suite (TMSS).
  • Lead the implementation of heuristic algorithms for search plan optimization, deterministic statistical roll-ups for Probability of Acquisition (Pacq), and 4/3 Effective Earth Radius models for terrain masking (using DTED).
  • Ensure robust data ingestion and export pipelines for tactical log data from radars and tactical binary search plan files (SPT, OSP, Custom XML).
  • Support the software team in adopting DoD DevSecOps best practices, ensuring all code meets rigorous cybersecurity standards for deployment in operational military environments.
  • Contribute to a team of software engineers and radar systems analysts in translating complex physics and engineering models into scalable, performant software code.

Minimum Requirements:

  • Bachelor's or Master's Degree in Computer Science, Software Engineering, Systems Engineering, or a highly related technical field.
  • 10+ years of full-lifecycle software engineering experience
  • Strong programming expertise in modern languages utilized for defense modeling and UI (C++, Java, Python).
  • Experience with XML data structures and parsing utilities.
  • Familiarity with geospatial data processing and coordinate geometry (e.g., Vincenty Direct formulas, DTED/TDF integration).
  • Experience developing software within the DoD Modeling and Simulation (M&S) enterprise.

Preferred Requirements:

  • Direct experience with phased-array radar systems
  • Familiarity with threat models
  • Knowledge of radar detection theory, Signal-to-Noise Ratio (SNR) tracking logic, and Scattering Center Radar Cross Section (RCS) models.
  • Previous experience supporting rapid prototyping and Warfighter Improvement Process (WIP) requirements.

Required Education: Candidates should possess a bachelor's degree, preferably in Engineering, Cyber, Computer Information Systems, Computer Science, Math, Physics, or other STEM discipline, however, years of experience may be substituted for a degree.

Eligibility: Candidates must have the ability to obtain and maintain a DoD Secret Clearance. An Active Secret Clearance is highly desired.
