RF Design Engineer – SoC

Octagon Group, Phoenix, AZ, United States


An exciting opportunity with a

specialist semiconductor design house

known for developing high-performance RF and mixed-signal SoC solutions used in advanced communications, sensing, and defense-related applications.

This is a

hands-on, system-level role

focused on RFSoC timing, synchronization, and validation, ideal for an engineer who enjoys working across the boundaries of RF, analog, and digital integration to ensure high-performance silicon delivery.

The Opportunity
You’ll join a highly technical, close-knit engineering team working on complex RFSoC platforms. The environment is fast-paced and innovation-driven, with real ownership across the design lifecycle and exposure to cutting-edge architectures.

Key Responsibilities

Define and validate system timing and synchronization across RFSoC subsystems (PLL, ADC, DAC, and digital processing blocks)

Ensure accurate clock distribution and phase alignment across multi-channel architectures

Support synchronization of parallelized ADC/DAC data paths, including down-sampling and decimation chains

Contribute to system-level validation, ensuring robust performance across integrated RF and mixed-signal blocks

Collaborate closely with design teams to solve complex integration and timing challenges

What We’re Looking For

Experience working on RFSoC or mixed-signal SoC design, with a focus on timing and validation

Strong understanding of clocking, synchronization, and multi-channel system architectures

Experience with Cadence tools (e.g. Tempus, Quantus) or equivalent toolsets

Background working with ADCs, DACs, PLLs, or similar high-speed mixed-signal components

Comfortable operating at system level, bridging RF, analog, and digital domains

Additional Info

Must be a U.S. Citizen or Green Card holder (ITAR/EAR requirements)

On-site role in Tempe, AZ, working closely with a highly experienced IC design team

Strong opportunity for technical ownership and progression within a growing, high-impact business

If you’re looking to deepen your expertise in RFSoC systems and take ownership of complex timing and synchronization challenges, this is a standout opportunity within a highly specialized semiconductor environment.
