Staff Platform Engineer, Platform Development

Denver, CO (Hybrid), San Antonio, TX (Hybrid), Brooklyn, NY or Remote (US Based)

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 Force's 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.

Staff Platform Engineer, Platform Development

Location: We prioritize candidates who reside in the Denver, CO, San Antonio, TX, and Brooklyn, NY areas, (hybrid as needed) but we are open to exceptional remote talent.

Department: Engineering

About Simplesense

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 what’s happening in time to act. That’s 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 Force’s 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.

About the Role

As our Staff Platform Engineer, you will play a critical role in owning the technical strategy, architecture, and delivery of the operational platform to enable rapid decision-making and data visualization for critical infrastructure. You will oversee the end-to-end success of core platform components—from cloud network architecture to performance and reliability—and partner closely with the Product and Operations teams to ensure our platform remains resilient, secure, and ready for the mission.

Work Model: We prioritize candidates who reside in the Denver, CO, San Antonio, TX, and Brooklyn, NY areas, (hybrid as needed) but we are open to exceptional remote talent.

  • Locals: Onsite as needed for collaborative workspace time.
  • Remote: Quarterly travel to hub locations for team syncs and alignment.

Our Performance Culture

We measure performance across two key dimensions: How you perform your role (Our Core Values) and What your role entails (Your Execution).

How You’ll Work — Our Core Values

At Simplesense, we value high-trust autonomy. We look for builders who can comfortably navigate ambiguity and are deeply driven by our shared national security mission.

  • People Always – Win as One Team: We foster a culture of psychological safety and mutual support. We operate as an integrated team where we assume noble intent as our default setting, ensuring that even the toughest feedback is rooted in trust. We trade our silos for a shared mission because collective impact always outweighs individual achievement.
  • Empathize – Obsess Over the Customer: We don't just solve technical problems; we empathize and advocate for the operators using our products. We look beyond the surface to build what our customers—both internal and external—actually need to succeed, not just what they asked for.
  • Focus – Ruthlessly Prioritize with Urgency: We focus on the highest-impact work and ruthlessly say no to distractions. We build resilient systems so that our solutions can repeat and scale under pressure.
  • Let’s Go – Catalyze the Change You Seek: We don't wait for the industry to change; we drive it. We seek to understand why things are the way they are, but we never use “the way it’s always been” as an excuse. We aren't afraid to change course when the data or our mission demands it.

What You’ll Do

  • End-to-End Technical Ownership: Serve as a technical owner for the success of platform development projects, from initial concept evaluation and design to final delivery and maintenance. Responsibilities will span new feature development and integration, cloud network architecture updates and implementation of performance and reliability improvements.
  • Internal and External Collaboration: Work closely with cross-functional Development, Product, and Operations teams, as well as external vendors, to ensure the platform meets stability, security, and scalability requirements on operational timelines.
  • Technical Leadership: Work with Engineering and Product leadership to ensure clear, actionable and achievable plans that span the organization.
  • System Design & Architecture: Lead planning sessions, create design documents, and make high-level technical decisions for core platform components (e.g., infrastructure-as-code, deployment pipelines, operational reliability, security controls, and disaster recovery planning).
  • Force Multiplier & Mentorship: Elevate the entire team by establishing best practices, conducting insightful code reviews, and unblocking teammates who are stuck, prioritizing the team's output over individual coding tasks.
  • Technical Contributor: Provide hands-on technical contributions for the most critical or demanding parts of the project, setting the technical pattern and standard for others, with a healthy time allocation of approximately 60% on solving technical problems (coding, design, reviews).
  • Team & Process Improvement: Dedicate time (approx. 40%) to planning, cross-team communication, defining scope with Product Owners, breaking down work, and identifying/fixing process issues (e.g., CI/CD pipelines, testing standards for platform components).

What You Bring

Required Qualifications:

  • Experience: 7–15 years of professional experience in building and delivering scalable, secure, and reliable systems and cloud services.
  • Technical Proficiency: Deep expertise with AWS systems and networking (e.g., EC2, SSM, VPCs, Route53, transit gateways), infrastructure automation (Terraform or CloudFormation), and proficiency in NodeJS or Python.
  • Domain Knowledge: Demonstrated understanding of replatforming or rehosting services within AWS environments, and proven experience at a Staff/Principal level navigating technical ambiguity to lead large-scale cross-functional efforts.
  • Travel: Ability to travel for a full week quarterly for team planning and client Program Management Reviews (PMRs).
  • Compliance: Must be a U.S. Citizen and capable of obtaining a DoD NIPR network account and Common Access Card (CAC). Must also hold or be willing to obtain a security-relevant certification (e.g., CompTIA Security+, Cloud+).

Preferred Qualifications:

  • Strongly prefer candidates residing in the Denver, CO, San Antonio, TX, or Brooklyn, NY metro areas (with a special emphasis on Denver, CO).

  • Relevant technical certifications, such as AWS Certified Solutions Architect or AWS Certified DevOps Engineer.
  • Experience with Windows domain environments and observability/monitoring tools (e.g., Splunk, Datadog).

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
