Full description
Lumen is the trusted network for the AI‑powered world, connecting people, data, and applications through our expansive fiber network and connected ecosystem. We enable secure, high‑performance connectivity across cloud, edge, and AI workloads for enterprises, governments, and communities.
At Lumen, you’ll work on infrastructure customers rely on today and build for what’s next, where performance, security, and resilience matter.
This is a high accountability environment where bold ideas drive real innovation for our customers, partners, and industry. The work is challenging, expectations are clear, and trust is built into how we operate. If you’re ready to take ownership, deliver meaningful impact, and help shape the future of AI‑ready connectivity, join us today.
The Role
You'll be the technical lead on Alkira deals — in the room with network architects and infrastructure directors, owning the technical side of the deal from first conversation through POC to close. You'll do that as part of an experienced Sales Engineering team, with senior SEs alongside you on the largest and most complex opportunities. This is a pre-sales engineering role. You'll partner directly with an Account Manager on strategy and carry real influence over what we build next — our Product team treats SE field feedback as a primary input to the roadmap. It's also a role you can grow in: you'll have senior SEs to learn from, and a clear path for career growth. Travel: approximately 25%, including regional air travel as needed.
The Main Responsibilities
Present and demo the Alkira platform to technical decision makers, from engineer to CIO
Clearly articulate the Alkira value proposition, with a good understanding of the market, industry and competitive landscape
Partner with Alkira Account Managers to understand customer requirements and pain points. Assist with any technical asks from customers and help respond to RFP/RFIs
Scope, run and win Proof of Concepts end to end, with senior SE support on the largest and most complex engagements
Assist customers with design and deployment based on best practices
Work with the Alkira Product Management team to provide feedback on upcoming features from the customer's lens
Track and drive key customer features/asks with Alkira Product Management to implementation
Contribute to the wider SE team — we review each other's designs, share what works in the field, and build the reusable material the whole team sells with
What We Look For in a Candidate
