Lumen

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.

  • Partner across Finance, FP&A, Data Science, and IT to turn business needs into practical solutions and actionable insights.
  • Contribute to high-impact initiatives that advance how data and AI are used across Finance.

What We Look For in a Candidate

  • 3–5 years of experience in data science, data engineering, analytics, or a related role
