Senior Telecom Jobs (NOW HIRING)

Senior Telecom Software Engineer
Herndon, VA | Hybrid (flexible, mission-dependent)

About the Job
Illuminate provides analytic and cyber solutions enabling critical decisions from vast data sources. As a
Senior Telecommunications Software Engineer, your primary focus will be deep telecommunications
network analysis – monitoring, diagnosing, and resolving performance issues across core network
infrastructure spanning 2G through 5G technologies.

You will serve as a critical technical resource for a CONUS-based engineering team that supports
OCONUS deployments, ensuring they have the analysis, data, and remediation guidance they need to

maintain mission-critical systems in the field. This role is CONUS-based and requires someone who can
work independently with deep protocol expertise – including familiarity with telco signaling and at-speed
handling of open flow data streams, and a strong understanding of how signaling presents across
network architectures.

You will work closely with a geographically distributed team, collaborating with operations and
development staff, and may be required to engage directly with government customers on-site or
participate in Program Management Reviews (PMRs) to present and explain technical support activities.

Why Illuminate
At Illuminate, you won’t be a ticket in a queue. This is a small, high-trust team where your expertise has
direct impact on missions that matter – supporting the U.S. national security community and its allies. The
work is technically demanding by design, and we expect senior-level ownership and independent
judgment. If you thrive in an environment that values results over process, and you’re looking for a role
where your telecom depth will be tested and valued daily, this is it. You’ll also be joining at a pivotal
moment – with a Linux infrastructure transition underway and a modernization roadmap ahead, there’s
meaningful work to shape, not just maintain.

What Success Looks Like
At 90 days, a successful hire is fully onboarded and independently handling network analysis, supporting
the CONUS-based engineering team with minimal oversight, and already engaged with the government
customer – including participation in at least one PMR. They are comfortable in the current CentOS 7
environment and contributing to Rocky Linux transition planning.

At 12 months, they own the network analysis function end to end, have driven or contributed meaningfully
to the infrastructure transition, and are the established technical resource the engineering team relies on
without hesitation. They’ve represented Illuminate credibly in customer-facing settings and are a
dependable, collaborative presence the broader team counts on.
