Senior Systems Engineer – Radar Analysis

Four Sea Group is a 100% employee-owned technical mission support company based in Denver, Colorado. Founded by an aerospace industry veteran and PhD astrophysicist, we support complex defense, space, software, systems, and mission-focused programs for government and industry partners. What sets FSG apart is the caliber of our people and the way we operate: we are a reputation-driven team of highly skilled engineers and technical experts who are brought in for their depth, judgment, and ability to solve difficult problems.

As an employee‑owned company, we have built our compensation, benefits, and culture around a simple idea: when the company succeeds, that value should go back to the people doing the work.

Four Sea Group is seeking a Senior Systems Engineer specializing in radar analysis to support the development, evaluation, and advancement of complex radar and mission capabilities.

This role contributes to Four Sea Group’s ability to help customers translate operational needs into technically sound, mission-effective solutions. The engineer will evaluate radar and signal‑processing performance, support the development and integration of algorithms, analyze system behavior, and help ensure that delivered capabilities meet mission objectives throughout the systems engineering lifecycle.

The ideal candidate combines strong radar and signal‑processing knowledge with systems thinking, analytical depth, and practical modeling or prototyping experience. This role requires the ability to independently own significant analytical efforts, evaluate technical tradeoffs, communicate findings to engineering and program stakeholders, and collaborate across software, systems, mission, and test teams.

Depending on background and program need, candidates may specialize in radar performance analysis, signal processing, algorithm development, tracking and state estimation, modeling and simulation, or mission‑level systems analysis.

• Bachelor’s degree in Engineering, Physics, Mathematics, Computer Science, or another relevant STEM field, or equivalent practical experience.
• Typically eight or more years of relevant systems engineering, radar, signal processing, mission engineering, algorithm development, or related technical experience.
• Active DoD Secret security clearance at the time of application
• Experience with radar systems and radar performance analysis.
• Experience applying signal‑processing concepts to complex technical or mission problems.
• Experience working through the systems engineering lifecycle, including translating system or mission requirements into analytical, algorithmic, or technical solutions.
• Experience performing functional, performance, or operational analysis of complex systems.
• Experience using MATLAB or comparable analytical tools for modeling, analysis, or code prototyping.
• Ability to independently plan and execute significant technical analysis efforts and synthesize results from multiple technical sources.
• Ability to evaluate technical performance, identify risks or tradeoffs, and communicate findings to engineering, program, and customer stakeholders.
• Strong problem‑solving, analytical reasoning, and technical communication skills.
• Ability to work effectively within cross‑functional engineering teams.

Candidates may bring expertise in one or more of the following areas:

• Radar architecture, mode development, or sensor performance analysis.
• Radar Blake Charts or comparable techniques for operational performance assessment.
• Development, integration, or evaluation of radar algorithms.
• Kinematic trajectory or threat analysis.
• Mission scenario modeling and simulation.
• Technology and system‑performance trade…
