Principal Network Architect

The Posterity Group is seeking a senior Principal Network Architect / Technical Program Lead to support a high-visibility U.S. Space Force mission in Colorado Springs.

This is not a traditional network engineering role. The customer is looking for a trusted technical advisor who can think strategically, challenge assumptions, evaluate complex technical tradeoffs, and help shape the future of mission networks and communications architecture.

The right candidate must be able to operate at both levels: big-picture architecture and detailed engineering.

Most importantly, the government technical lead needs someone he can trust to make sound decisions, maintain momentum, and represent the program effectively when he is unavailable.

Responsibilities Develop and evaluate current- and future-state network architectures. Translate mission requirements into executable technical solutions. Support network modernization, systems integration, and technical roadmapping. Evaluate architectural alternatives across mission impact, cost, schedule, risk, interoperability, resiliency, and cybersecurity. Lead and participate in architecture reviews, engineering working groups, technical interchange meetings, and design reviews. Review network designs, interfaces, engineering artifacts, and implementation plans. Coordinate across government, engineering, cybersecurity, program management, and contractor teams. Identify technical risks and integration issues before they become program problems. Provide clear recommendations to senior government leadership. Support technical program management, requirements, risk, configuration, and execution activities. Desired Technical Background, Experience supporting U.S. Space Force, U.S. Space Command, MDA, Combatant Commands, SATCOM, C2, or other mission-critical DoD communications environments is highly desirable.

The Bottom Line

When the government technical lead steps away, he needs confidence that the right person is still at the table.

If you have the technical depth to understand the details, the judgment to see the larger picture, and the confidence to say either “this will work” or “we need a better approach”-and explain why-we’d like to talk to you.

Candidates should be technically credible in areas such as BGP, OSPF, routing policy, bandwidth, latency, transport, network security, interoperability, and architectural tradeoffs, even if they are no longer performing daily hands-on configuration.

What We Value

We are looking for someone who:

Thinks independently and strategically. Is comfortable challenging assumptions professionally. Can explain why one technical approach is better than another. Understands when to push back and when to take direction. Can work through ambiguity without constant supervision. Communicates effectively with both engineers and senior government leaders. Balances technical excellence with program cost, schedule, and mission needs.

We are not looking for a yes-person.

We are looking for someone whose judgment is trusted because it is technically grounded, thoughtful, candid, and mission focused.
