Solution Engineer (Open RAN)

Eridan • Sunnyvale, CA

12h • $130,000 - $160,000 • Hybrid

About The Position

We’re looking for a Solution Engineer to 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 CU all the way down to the radio. This is not a coding role; it’s a systems role for someone who understands how every part of a disaggregated RAN works well enough to make them all talk to each other. 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.

Requirements

• BS in Electrical Engineering, Computer Science/Computer Engineering, Telecommunications, or equivalent experience.
• 5+ years in telecommunication, network, or systems engineering (we’ll consider 3+ years with strong RAN experience).
• Fluency in Linux and the command line: navigating systems, editing configuration files, reading logs.
• Solid understanding of RAN architecture — specifically Open RAN and disaggregated CU/DU/RU systems.
• Solid debugging skills in all different RAN layers (L1, L2, L3).
• Networking fundamentals: VLAN tagging, interface debugging, routing.
• Working knowledge of 5G NR concepts: PRBs, channel bandwidth, TDD patterns, and how they affect system behavior.
• Excellent written communication and the ability to run a project with external partners.
• A hands-on, roll-up-your-sleeves mindset — lab work, moving equipment, and outdoor field testing are part of the job.

Nice To Haves

• O-RAN 7.2a fronthaul split / lower-layer split interface experience; physical-layer familiarity.
• RF background.
• Customer-facing experience.
• Experience with Kubernetes, Docker, etc.
• Experience with test tools such as Wireshark, QualiPoc, Keysight, XCAL/XCAP, QXDM, etc.
• Python scripting.
• MS in Telecommunications.
• Ability to travel internationally (Europe and Asia).

Responsibilities

• Manage partner integration projects autonomously, end to end — from first technical exchange to confirming the integration is complete and optimal.
• Communicate directly with partner engineers: explain technical requirements, drive debugging, and keep projects moving.
• Validate end-to-end system and network performance (core → CU → DU → RU → UE) against RF and network parameters, in the lab and in the field.
• Validate new RU software releases against integrated end-to-end systems.
• Integrate new features into end-to-end systems: new software versions, new devices on the network, and new radio variants (e.g., 4T4R, 100 MHz).
• Work with different debugging tools, from Keysight RF testing tools to Viavi emulators and Wireshark.
• Debug across Linux systems, network switching and fronthaul, and RAN configuration layers.
• Conduct integration validation and field testing — controlled, repeatable measurement campaigns.

Benefits

• Pre-IPO equity
• 401K with automatic match
• Health, Vision and Dental insurance
