Senior System Specialist

Simplesense builds deploys and sustains the Installation Resilience Platform that enables mission operators to rapidly adapt and respond. The Platform protects critical infrastructure from cyber attack while unlocking previously siloed information to monitor diagnose and improve response times to incidents. Our adversaries rapidly adopt the latest technology: we help defense users respond in kind.

Simplesense is a non-traditional defense contractor and prime on the Air Forces Installation Resilience Operations Command and Control (IROC) program which is now expanding to five additional Air Force Space Force and Army installations from the one prototype installation Tyndall Air Force Base.

Our team combines over 100 years of direct mission experience solving hard problems with 50 years technical expertise deploying DevSecOps cybersecurity and cloud infrastructure giving us a deep appreciation for our customers mission and end users priorities. We build for scale architecting and prioritizing technical work for long term sustainability.

Location: We prioritize candidates who reside in the Denver CO metro area (hybrid as needed) but we are open to exceptional remote talent.

Department: User Success

Simplesense keeps military installations mission-ready. The infrastructure their operations depend on power water fuel facilities security and communications runs continuously often under strain. When it fails without warning mission readiness is at risk and the people who run these installations need to see whats happening in time to act. Thats the foundation of Continuous Mission Assurance.

We securely integrate Operational Technology and Control Systems (OT/CS) from the building edge to the cloud applying Zero Trust principles to protect critical infrastructure from cyber and physical threats. By unlocking previously siloed data we put timely awareness in front of the decision-makers who need it. As prime on the Air Forces Installation Resilience Operations Command and Control (IROC) program we hold a continuous Authority to Operate (ATO) and have proven the capability at scale at Tyndall Air Force Base. That work is now expanding across the Air Force Space Force and Army.

Our team pairs over a century of boots-on-the-ground mission experience with deep technical expertise across DevSecOps cybersecurity and cloud infrastructure. We engineer resilient infrastructure the software integration and operational backbone behind it for the operators who depend on it in the field. Persistent resilience built for the mission.
