Learn more about our mission [here](https://www.youtube.com/watch?v=SKKOj_wcZ_0).

## About this Job

Help design the communication technologies that connect today's robots and power the physical AI era.

We're hiring an early-career RF hardware systems engineer who wants to spend real time in the lab. You'll join our systems engineering team and work alongside senior engineers on Eridan's 5G radio products: characterizing RF performance, bringing up boards, and chasing down bugs until they're fixed.

This is a hands-on role with fast learning built in. You'll own well-defined pieces of the radio from the start, and take on more of the system as you grow.

## What you'll do

- Get hands-on in the lab. Bring up new boards, run RF characterization and validation, and debug issues at the board and subsystem level.
- Contribute to the radio design. Support schematic and PCB development for RF subsystems, including transceiver chains, impedance-controlled layout, power distribution, and  high-speed digital.
- Verify against the spec. Help define test plans, run measurements, and report results against system requirements for our 5G radio products.
- Work across teams. Partner with hardware, firmware, software, and Test teams to turn design decisions into clear requirements and resolve integration issues.
- Help get it to production. Support design reviews and qualification so our products are ready to manufacture at volume.
- Automate what you repeat. Write scripts to speed up lab testing and data analysis.

## Minimum Qualifications

- Education: B.S. or M.S. in Electrical Engineering or a related technical field
- Experience: 2+ years of hands-on industry experience in RF hardware or RF systems engineering
- RF fundamentals: Working knowledge of RF signal chains (LNAs, PAs, mixers, filters, PLLs) and key RF performance metrics such as gain, noise figure, linearity, and EVM
- Hardware design: Experience with schematic capture and familiarity with RF PCB layout practices such as impedance control and grounding
- Lab skills: Hands-on use of RF test equipment such as spectrum analyzers, VNAs, and signal generators for board bring-up and debug
- Communication: Clear communicator who asks questions, shares findings, and works well with cross-functional teams
- Work authorization: Must be legally authorized to work in the U.S. without current or future employer sponsorship or visa transfers

## Nice to Have

- Exposure to 5G or LTE radio hardware (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, or Ansys HFSS/SIWave
- Scripting in Python, MATLAB, or C# for test automation and data analysis
- Understanding of communications theory
- Experience at a startup or growth-stage hardware company

## Why you'll love working here

- Build the wireless technology that connects robots and powers the physical AI era, with real impact on global infrastructure
- Work where AI meets wireless, from robotics to AI-native networks (AI-RAN)
- See your work ship: on our lean team, there are no layers between your ideas and the product
- Grow your career on a team that owns its work, speaks candidly, and celebrates progress together
- Pre-IPO equity
- 401(k) with automatic match
- Health, vision, and dental insurance

Salary Range

Given our anticipated growth, we are open to hiring individuals with varying levels of experience to fill this role. Salary will be commensurate with job-related skills, experience and other relevant factors. The base salary range for the primary location of this role is between $120,000 and $145,000 plus stock options and benefits.

Eridan is an equal opportunity employer. We value and celebrate diversity and are committed to creating an inclusive environment for all employees. Qualified applicants will be considered for employment without regard to race, color, religion, sex, national origin, sexual orientation, gender identity, disability or protected veteran status.

## About Eridan

## Company Overview
- **One-liner**: Eridan is a U.S.-based technology company that has developed a fundamentally new radio architecture using direct polar modulation and Gallium Nitride to deliver high-performance, low-power, and low-cost 5G connectivity for private networks, rural broadband, industrial sites, and national infrastructure.
- **Entity Type**: Private (rapidly growing startup; pre-IPO equity offered)
- **Headquarters**: Sunnyvale, California, United States
- **Founded**: Not publicly available (leadership team with decades of experience suggests a recent startup; exact year not listed)
- **Founders**: Douglas Kirkpatrick (Co-Founder & CTO), Dubravko Babić (Co-Founder & President, Eridan Croatia); key executives include Omid Tahernia (President & CEO) and Atiq Raza (Executive Chairman)

## Core Business
- **Primary industry**: Wireless telecommunications / 5G infrastructure / Open RAN hardware
- **Target customers**: Enterprises deploying private 5G, mobile network operators, industrial/utility sites, rural broadband providers, and national defense organizations (B2B primarily)
- **Mission or purpose**: "To connect the planet to empower a sustainable, shared future" by making 5G connectivity affordable and energy-efficient everywhere.

## Products & Services
- **[Digital Radio Unit with Ultra-Clean Signal™]**: A fully digital, polar modulation-based radio built using Gallium Nitride (GaN) that delivers up to 5× lower power consumption and significantly reduced size and cost versus legacy systems. Supports Open RAN architectures and achieves high spectral efficiency for AI-driven and high-demand applications. Deployed for Private 5G, rural broadband, and industrial use cases.

- **[Field-Tested Performance]**: In public demonstrations, Eridan sustained over 100 Mbps at 1.7 km using only 0.3 watts, proving viability for long-range, low-power connectivity.

## Market Standing
