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. Learn more about our mission here.

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.
• Run field campaigns. Plan and carry out controlled, repeatable measurement campaigns at partner and customer sites.

What you bring

• Strong, hands-on Linux experience (required). You work on the command line every day: installing and provisioning new firmware, navigating systems, editing configuration files, reading logs, managing services and network interfaces, and troubleshooting when something won't come up.
• BS in Electrical Engineering, Computer Science/Computer Engineering, Telecommunications, or equivalent experience, plus 5+ years in telecom, network or systems engineering (we'll consider 3+ years with strong RAN experience).
• Solid understanding of Open RAN and disaggregated CU/DU/RU architecture, and the ability to debug across L1, L2 and L3.
• Working knowledge of 5G NR (PRBs, channel bandwidth, TDD patterns and how they affect system behavior) and networking fundamentals (VLAN tagging, interface debugging, routing).
• Clear written communication, the ability to run projects with external partners, and a hands-on mindset. Lab work, moving equipment, and outdoor field testing are part of the job.
• Work Authorization: Must be legally authorized to work in the U.S. without current or future employer sponsorship or visa transfers

Nice to have

• O-RAN 7.2a fronthaul / lower-layer split experience, physical-layer familiarity, an RF background or an MS in Telecommunications.
• Experience with test tools such as Wireshark, QualiPoc, Keysight, XCAL/XCAP or QXDM, plus Python, Kubernetes or Docker.
• Customer-facing experience and the ability to travel internationally (Europe and Asia).
• Interest in private 5G for robotics, autonomous systems or industrial automation.

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
