Solution Engineer (Open RAN)

About the role

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 CU all the way down to the radio.

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.
• 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).
• Debug across Linux systems, network switching and fronthaul, and RAN configuration layers.
• Conduct integration validation and field testing — controlled, repeatable measurement campaigns.

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.

Qualifications

• Nice to have: O-RAN 7.2a fronthaul split / lower-layer split interface experience; physical-layer familiarity.
• 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).

Benefits

Perks of working at Eridan: Work on new technology that will make a significant impact on global infrastructure; Ability to learn, develop, and advance within a flexible environment; Collaborate with smart, passionate, and helpful co-workers; Celebrate progress company-wide; Pre-IPO equity 401K with automatic match; Health, Vision and Dental insurance.

Pay

The base salary range for the primary location of this role is between $130,000 and $160,000 plus stock options and benefits.

Schedule

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.
