About The Position

Eridan is hiring an early-career RF hardware systems engineer to help develop its 5G radio products. The role is part of the systems engineering team and involves hands-on laboratory work alongside senior engineers, including RF performance characterization, board bring-up, and debugging. The engineer will initially own well-defined parts of the radio system and take on broader responsibilities as they grow. The position contributes to radio design, validation, cross-functional integration, and production readiness, and includes automating recurring laboratory tests and data analysis.

Requirements

• B.S. or M.S. in Electrical Engineering or a related technical field.
• At least 2 years of hands-on industry experience in RF hardware or RF systems engineering.
• Working knowledge of RF signal chains, including LNAs, PAs, mixers, filters, and PLLs, and RF performance metrics such as gain, noise figure, linearity, and EVM.
• Experience with schematic capture and familiarity with RF PCB layout practices such as impedance control and grounding.
• Hands-on experience using RF test equipment such as spectrum analyzers, VNAs, and signal generators for board bring-up and debugging.
• Clear communication skills, including asking questions, sharing findings, and working effectively with cross-functional teams.
• Must be legally authorized to work in the U.S. without current or future employer sponsorship or visa transfers.

Nice To Haves

• Exposure to 5G or LTE radio hardware, such as O-RAN, small cell, or macro radio; cellular TDD/FDD systems; or 3GPP specifications.
• Experience with RF simulation tools such as Keysight ADS or Cadence AWR.
• Scripting experience in Python, MATLAB, or C# for test automation and data analysis.
• Understanding of communications theory.
• Experience at a startup or growth-stage hardware company.

Responsibilities

• Bring up new boards and perform RF characterization, validation, and board- or subsystem-level debugging.
• Support schematic and PCB development for RF subsystems, including transceiver chains, impedance-controlled layout, and power distribution.
• Help define test plans, perform measurements, and report results against system requirements for 5G radio products.
• Work with hardware, firmware, software, and Test teams to clarify requirements and resolve integration issues.
• Support design reviews and qualification to prepare products for volume manufacturing.
• Write scripts to accelerate laboratory testing and data analysis.

Benefits

• Pre-IPO equity and stock options.
• 401(k) with automatic match.
• Health insurance.
• Vision insurance.
• Dental insurance.
