Senior Staff Engineer - CATV RF Design

We are seeking a highly experienced Senior Staff Engineer with deep expertise in CATV RF and HFC network design, including active device architecture and amplifier design. This role serves as a senior technical authority responsible for the design, optimization, and modernization of broadband HFC networks and the active components that power them. The ideal candidate brings 15+ years of progressive RF engineering experience within the cable telecommunications industry and demonstrates strong technical leadership, innovation, and cross-functional collaboration.

• Lead end-to-end RF design and architecture for CATV/HFC networks including system expansion, segmentation, node splits, and capacity upgrades
• Develop cascade designs including amplifier spacing, tilt planning, equalization strategy, and link budget analysis
• Perform forward and return path design including mid-split, high-split, and extended spectrum DOCSIS implementations
• Support fiber deep, DAA (Remote PHY/Remote MACPHY), and DOCSIS 3.1/4.0 evolution strategies
• Define and maintain RF design standards, engineering guidelines, and performance metrics
• Design and optimize broadband RF amplifier stages for HFC applications across 5 MHz–1.8 GHz (and beyond for extended spectrum)
• Develop gain stage architectures including push-pull and GaN/LDMOS-based output stages
• Perform distortion analysis including CCN and NPR performance
• Design automatic gain control (AGC) and automatic level control (ALC) systems
• Engineer equalization networks and slope compensation to maintain flatness across extended bandwidth
• Analyze thermal performance, power dissipation, and efficiency of amplifier modules
• Evaluate noise figure, return loss, isolation, and impedance matching performance
• Support power supply integration, standby powering schemes, and surge protection design
• Conduct simulation and modeling using RF design tools (e.g., ADS, Microwave Office, SPICE-based modeling)
• Lead validation testing including sweep alignment, MER/SNR performance, ingress resilience, and field qualification
• Experience with Altium CAD software tools
• Conduct system-level performance analysis including MER, SNR, group delay, distortion products, and return path noise
• Optimize cascade depth and amplifier count to balance performance, cost, and reliability
• Lead troubleshooting of plant impairments related to active device nonlinearities or misalignment
• Collaborate with operations teams on deployment, activation, and field support
• Serve as subject matter expert on RF active devices and HFC architecture
• Mentor junior engineers and guide technical development of the organization
• Partner with product, operations, and executive leadership on long-term network strategy
• Evaluate vendor components, silicon technologies, and emerging architectures
• Support compliance with SCTE, ANSI, and FCC standards

• Bachelor’s degree in Electrical Engineering or related technical discipline (required)
• Master’s degree in Electrical Engineering or related field (preferred)
• 15+ years of experience in CATV/HFC RF design
• Direct experience designing or architecting broadband RF amplifiers for HFC systems
• Strong understanding of RF transmission theory, impedance matching, and nonlinear distortion mechanisms
• Extensive knowledge of DOCSIS 3.0/3.1/4.0 and extended spectrum evolution
• Experience with RF modeling and simulation tools
• Proven ability to lead complex technical initiatives

• Experience with GaN or LDMOS device technologies in broadband applications
• Familiarity with digital predistortion (DPD) techniques
• SCTE certifications (SCTE-T, SCTE-IE)
• Experience leading extended spectrum or DOCSIS 4.0 deployments
• Background in hybrid analog/digital amplifier module design

This position will be on-site based in Duluth, GA.

In addition to competitive salary, AOI offers

• Flexible and competitive health (medical, dental, vision) plans offer the employee with the right options to meet individual and family needs
• Employer matching on 401(k) deferrals
• Generous PTO policy, with unused PTO payout at end of the year
• Relocation package available within US
• Immigration sponsor ships (Must be currently authorized to work in the US)
