• Design Tradeoffs: Evaluate and balance design tradeoffs to optimize the performance and efficiency of RF systems software components.

• Technical Standards: Define and enforce technical standards for RF systems software and firmware to ensure consistency, interoperability, and maintainability.

• Cross-Disciplinary Collaboration: Work closely with RF hardware engineers, system architects, and other domain experts to integrate software components within RF systems.

• Requirements Definition: Support the definition and refinement of high-level and non-functional requirements for RF systems, ensuring alignment with project goals and stakeholder needs.

• Component Identification: Determine the necessary software solution components and subsystems for RF systems, including their interfaces and interactions.

• Technical Direction: Provide clear technical direction and guidance to other staff regarding the implementation of RF software architectures.

• System Optimization: Collaborate with RF system engineers to optimize the performance and efficiency of software components within the larger RF system context.

• Prototyping and Simulation: Utilize RF simulation tools and environments to prototype and validate software designs.

• Documentation: Create comprehensive documentation of software architectures, design decisions, and technical standards.

Qualifications

Required:

• 10 years of proven experience in RF software architecture and design.

• In-depth knowledge of RF technologies, including antenna design, signal processing, modulation techniques, and wireless communications protocols.

• Experience with RF software tools (e.g., MATLAB, Simulink, Python).

• Strong understanding of real-time operating systems and embedded systems.

• Excellent analytical and problem-solving skills.

• Ability to communicate complex technical concepts effectively to both technical and non-technical stakeholders.

• Experience with defining and enforcing technical standards and best practices.

Desired:

• Familiar with SDR (Software-Defined Radio) platforms and technologies.
