Job description

Alkira, a Lumen company, is a fast-growing cloud networking company that is transforming the way enterprise networks are deployed and managed.

We are looking for a Software Engineer with Control/Routing skills. The SE will develop software for Alkira's CSX (Cloud Services Exchange). The work will involve design, development & debugging of the software responsible for the networking functions that drive Alkira's CSX.

Responsibilities

The Software Engineer will perform the requirements from PLM/Sales teams and work with team members to design and implement the feature. You will take ownership of their work and follow-through on defects reported.

Requirements

• B.S. or equivalent in EE or CS, plus a minimum of 2 years of hands-on experience in networking or routing software development.
• Strong programming skills in Go (primary) and C — the team works daily in Go for control-plane services and in C for the FRR routing protocol stack.
• Deep, hands-on understanding of networking fundamentals and IP routing; BGP knowledge preferred.
  Experience with FRR, ZebOS, or equivalent open-source routing stacks preferred.
• Strong Linux networking fundamentals: interfaces, namespaces, the kernel routing/forwarding path, and routing-related tooling preferred.
• Experience designing and implementing multithreaded systems preferred.
• Systematic debugging and root-cause analysis skills for live routing issues. Fluency with using AI for tool development preferred.
• Ability to work in geographically distributed teams across US and India.
• Familiarity with cloud networking across major providers (AWS, Azure, GCP) — VPC/VNet constructs, peering, transit gateways, and how cloud networking interactswith routing preferred.

Nice to Have

• Deeper expertise in L2/L3VPN.
• Experience with VPN/remote-access technologies (OpenVPN or comparable tunneling).
• Experience with ZTNA / zero-trust remote access solutions.
• Familiarity with the data path (encryption, NAT, overlay tunnels) and how it interacts with routing.

ON-CALL

On-call is a mandatory part of this role. You'll join the on-call rotation and help debug and resolve production provisioning issues, with coverage coordinated across the US and India. It's also where a lot of the deepest learning happens — there's no faster way to understand a system than to keep it running.

Location and Sponsorship

We're looking for a candidate who is currently based in the San Francisco Bay Area and already authorized to work in the U.S. Unfortunately, we're not able to offer visa sponsorship for this role at this time, as well as relocation bonus. This position is a hybrid role and requires onsite collaboration with the team at San Jose, CA office.
