## Job description

## About Eridan

Eridan connects the robots powering the physical AI era. It's how we're delivering on our mission: connect the planet to empower a sustainable, shared future. Our patented transmitter delivers the fast, reliable wireless that robots depend on, while transforming the economics of connectivity, slashing costs and energy footprint by 10x at a global scale. Beyond robotics, our private 5G networks serve campuses, cities, industry, and defense. From our headquarters in Sunnyvale to our office in Zagreb, we're a team that owns our work, speaks candidly, and moves with focus and urgency.

## About the Role

Build the end-to-end networks that connect today's robots and power the physical AI era.

We're looking for a Solution Engineer to join our Solutions team and own integrations between partner CU/DU stacks and Eridan's RU. You'll be the technical face of Eridan to our integration partners: explaining requirements, configuring and debugging systems, and validating that end-to-end performance is optimal, from the core all the way down to the radio. This isn't a coding role, but you'll live on the Linux command line. It's a systems role for someone who understands every part of a disaggregated RAN well enough to make them all talk to each other. The networks you bring up and validate are the ones robots, autonomous vehicles and smart factories will rely on, where latency and reliability decide whether a machine keeps moving.

You'll split your time roughly 85% in our lab and 15% in the field, with the opportunity to travel to partner and customer sites, including internationally.

## What you'll do

- Bring systems online. Lead end-to-end Open RAN bring-up (core, SMO, CU, DU, RU). Validate new software, devices, and advanced radio variants (e.g., 4T4R, 100 MHz) in lab and field settings. Partner with internal Software and R&D teams to integrate features and build new system capabilities.
- Prove performance across the whole chain. Validate core → CU → DU → RU → UE performance against RF and network parameters, in the lab and in the field, including latency- and uplink-sensitive use cases like robotics and teleoperation.
- Own partner integrations end to end. Run projects on your own, from first technical exchange to a complete, optimized integration. Work directly with partner engineers to explain requirements, drive debugging and keep things moving.
- Debug at every layer. Track down issues across Linux systems, network switching and fronthaul, and RAN configuration, with tools from Keysight to Wireshark.

## 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 $130,000 and $160,000 plus stock options and benefits.

Work Authorization: Must be legally authorized to work in the U.S. without current or future employer sponsorship or visa transfers

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
- **Valuation/Market Cap**: Not disclosed (private company)
- **Key Metric**: Company claims its novel transmitter architecture decreases the cost and power required to roll out 5G by **10 times**; total funding rounds not publicly listed.
- **Notable Investors/Partners**: Backed by a leadership team with backgrounds at DARPA, Qualcomm, AMD, Motorola, Xilinx, and Ikanos; specific institutional investors not named in available materials.
- **Growth Signals**: Active hiring (multiple engineering roles in Sunnyvale and Zagreb, Croatia), growing team with presence in two countries, field validation results, and inclusion in Open RAN ecosystem discussions.

## Competitive Advantages
- **Ultra-Clean Signal™**: Proprietary polar modulation technology that eliminates the power/performance trade-off of traditional radios, allowing longer range and higher capacity at much lower power.
- **GaN-based design**: Enables higher efficiency and smaller form factor than legacy silicon-based radios.
- **Cost and power reduction**: Up to 10× lower roll-out cost and 5× lower power consumption compared to traditional 5G equipment.
- **Proven leadership**: Team combines deep expertise in RF, semiconductor, defense communications, and large-scale hardware/software execution.

## Strategic Focus
- Expand Private 5G adoption in industrial (smart factories, AI-driven automation), rural broadband, and national infrastructure segments.
- Continue optimizing the radio for Open RAN integration and compliance.
- Scale production and drive down unit costs to make pervasive connectivity economically viable.
- Leverage field test results to build credibility with operators and enterprise buyers.

## Why Work Here
- **Culture**: "Casual and energetic environment" with collaboration and communication driving outsized results. The Sunnyvale office features big windows (even in the lab), is walking distance to downtown and Caltrain, and fits the entire team for company parties.
- **Remote/Hybrid Policy**: Not explicitly stated, but on-site roles are listed (Sunnyvale and Zagreb); likely office-centric with some flexibility.
- **Notable Perks & Benefits**: Pre-IPO equity, generous PTO, 401(k) with automatic matching, and health/dental/vision insurance. Emphasis on empowering employees and building a productive work environment.
- **Engineering Culture**: Hands-on work with cutting-edge RF, GaN, and digital signal processing; small, growing team offering significant impact and visibility. The company is solving hard physics and engineering challenges in wireless.
