Dennis Wijers Fairfax, Virginia

Hello, I’m Dennis

I lead technical programs in space, cloud, and national security.

I work with engineers, operators, security teams, and government customers to make complex systems useful, secure, and dependable.

I’m based in Fairfax, Virginia, and currently work with Amazon Leo Government.

What I’m doing now

Amazon Leo Government

Amazon Leo is building a low-Earth-orbit satellite network for customers who need reliable connectivity beyond the reach of existing infrastructure.

My work is on the government field-operations side. I focus on support-platform architecture, systems integration, identity, and the engineering work needed to support a complex service in the field.

Selected work

Three programs that shaped how I work.

Each one required technical judgment, steady coordination, and a clear understanding of the mission behind the system.

GPS Directorate · 2016 to 2017

GPS acquisition and program decisions

On the GPS Program Executive Officer staff, I supported governance of a $32B portfolio. My work included GPS III funding, OCX control-segment risk, and a gap-filler strategy for senior leaders.

Nuclear detection · 2014 to 2016

A global ground system for trusted warning

I led a $20M-per-year program across nine sites, working within a mission supported by Sandia and Los Alamos expertise. We forecast 20% lifecycle savings and delivered a $3M modernization 30 days early.

NRO · 2017 to 2021

Moving mission data across boundaries

I led a 55-person, $50M+ portfolio that integrated OPIR data and 15 additional feeds. The team moved a cross-domain platform from concept to a $10M deployment and secured a $26M follow-on.

What I want to do next

Keep working on difficult, useful technology.

I’m most interested in roles where commercial technology and public-sector missions meet. That could mean satellite connectivity, practical AI, secure infrastructure, or another field where the technical and organizational problems are tightly connected.

I do my best work when I can help a strong team find clarity, make good decisions, and turn a promising idea into something people can rely on.
