Lead Systems Engineer – System Design, EW & SIGINT (Remote)

• *Company Description** XONE develops advanced RF geolocation and sensing systems to support critical defense and intelligence missions, including signal reconnaissance, surveillance, threat detection, and force protection. The company’s products are operationally proven and built on state-of-the-art hardware, embedded processing, and high-performance signal-processing architectures, with intuitive operator workflows that reduce cognitive load in demanding environments. XONE’s technology portfolio spans compact, platform-flexible RF sensors and FPGA/GPU-accelerated signal-processing architectures capable of supporting wideband, full-take geolocation missions in complex and dynamic RF conditions. These systems are designed for deployment on airborne, maritime, ground, and unmanned platforms, with support for autonomous and distributed operations, and they leverage software-defined radio techniques and open standards to ensure extensibility, interoperability, and seamless integration with customer ecosystems. By collaborating closely with end users, operations centers, and program offices, XONE ensures that capabilities deliver maximum mission impact at the tactical edge.

• *Role Description**

We are seeking a senior-level Systems Engineer to lead the definition, architecture, and technical execution of advanced RF sensing and communications systems. This role spans early concept development through prototype realization and customer delivery, with a strong emphasis on system-level thinking, technical rigor, and cross-disciplinary leadership. Our products integrate software defined radios, embedded processing, FPGAs, RF hardware, and small-form-factor platforms deployed in airborne, maritime, and ground environments. This position is well-suited for an engineer who enjoys shaping systems from first principles, translating operational needs into concrete designs, and working hands-on with hardware and engineering teams to turn concepts into working prototypes. You will operate as a technical focal point across disciplines, interface directly with customers and prime contractors, and work closely with the Chief Engineer on product direction and roadmap planning. This position can be based remotely.

• *Responsibilities**

• Lead system-level design activities including concept development, CONOPS analysis, requirements definition, and architecture trade studies

• Establish and maintain technical baselines, including system architectures, interface definitions, requirements allocations, and design documentation
• Decompose system architectures into clear, actionable work packages for software, FPGA, RF, and hardware engineering teams
• Design and prototype hardware-centric systems, working closely with engineering teams and external vendors on component selection, part surveys, and trade studies
• Perform RF and system analyses such as link budgets, noise and interference analysis, and performance modeling to inform design decisions
• Define DSP and signal processing approaches for SIGINT and electronic warfare capabilities at the system level and guide their implementation and mapping to hardware and software resources
• Analyze integration and test results, correlate performance across subsystems, and drive root-cause analysis of system-level issues
• Prepare and deliver technical briefings, design reviews, and performance assessments for internal leadership, customers, and partners
• Interface directly with customers and prime contractors on system capabilities, requirements, schedules, and technical risks
• Collaborate with the Chief Engineer on product roadmaps, R&D initiatives, and longer-term technology investments
• Support all phases of the product lifecycle including R&D, prototyping, integration and test, system delivery, and sustainment
• *Key Qualifications**

• 8+ years of experience in systems engineering, RF systems, embedded systems, or a closely related technical field

• Strong system-level background with experience defining architectures, requirements, and interfaces for complex, multi-disciplinary systems
• Broad technical understanding across RF, digital signal processing, embedded software, FPGA-based processing, and hardware platforms
• Practical experience performing RF and system analysis (e.g., link budgets, performance modeling, trade studies)
• Experience translating high-level operational needs into implementable technical designs and requirements
• Proven ability to lead technical efforts across multiple engineering disciplines without direct line authority
• Experience analyzing test and integration data and communicating results clearly to technical and non-technical audiences
• Excellent written and verbal communication skills, including customer-facing technical presentations
• Ability to o
