Department: Application Engineering

About Eridan

At Eridan we believe in the power of collaboration and communication to achieve our mission: connect the planet to empower a sustainable, shared future. That mission is possible with our patented transmitter which decreases the cost and power required to roll out 5G by 10x when deployed globally. This is all facilitated through our offices: our Sunnyvale headquarters has big windows (even in the lab!), is walking distance to downtown and the Caltrain, and fits the entire team in the cafeteria for our frequent company parties.

About this Job

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. 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.

What You’ll Do

• 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.

What You Bring

• 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 Have

• 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).

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
