Job summary

Leaf Space in Lomazzo (Como), Italy, is seeking a Senior RF Systems Engineer to own the RF/communications architecture for TreeNet. You will drive link-budget decisions, define MAC/PHY behavior, and interface with external node designers, turning architectural choices into actionable requirements.

You will lead verification, contribute to simulations, support DSP implementations on FPGA/processor, and work in a fast-moving, hybrid-work environment with strong cross-functional collaboration and

Qualifications

• MSc (or equivalent) in Telecommunications Engineering, Electrical Engineering, Aerospace Engineering, Physics, or a closely related field.
• 7+ years of professional experience in RF systems engineering, communications systems, or satellite communications, with demonstrated experience contributing to architecture-level decisions.
• Proven track record with link budget analysis and design for space or other long-range RF systems.
• Experience working directly with external hardware vendors/developers on RF interface and performance requirements.

Responsibilities

• Own the RF/communications architecture and drive its evolution throughout the product lifecycle.
• Lead link budget engineering across multiple configurations.
• Design and specify MAC/PHY layer behavior, including channel access strategy.
• Drive availability and performance analyses across orbital scenarios translating orbital mechanics constraints into RF design requirements.
• Act as the primary RF/comms technical counterpart to the external node designer/producer: reviewing their designs, resolving interface and performance issues, and ensuring their implementation matches TreeNet's architectural intent.
• Translate architectural decisions into concrete requirements and specifications consumable by hardware/firmware teams and external partners.
• Support verification and validation activities (test campaigns, simulation-to-hardware correlation) for RF/comms performance claims.
• Contribute to and review technical deliverables: architecture documents, analysis reports, and supporting simulation/analysis code.
• Support development and implementation of DSP algorithms for implementation on FPGAs and processors
• Provide support to regulatory team for licensing matters and coordination.
• Act as the point of contact for relevant subject matter with test partners and early adopters
