Senior Platform Engineer - Connectivity

Senior Platform Engineer, Connectivity

Location: We prioritize candidates who reside in the Denver, CO metro area (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 Senior Platform Engineer, Connectivity, you will play a critical role in securely and efficiently onboarding customer facilities into our cloud-hybrid platform services. You will oversee the design and implementation of scalable infrastructure automation, tooling, Linux systems, and networking workflows, and partner closely with the Connectivity and broader engineering teams to ensure our platform remains resilient, secure, and ready for the mission.

Work Model: We prioritize candidates who reside in the Denver, CO area (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

• Automation and Infrastructure-as-Code: Lead the design and implementation of reusable tooling and configuration-driven workflows that automate the lifecycle management of Connectivity infrastructure.
• Linux & Network Systems: Develop and maintain automation for Linux-based systems and network appliances, including secure configuration generation, system bootstrapping, software updates, and validation routines.
• Connectivity Workflow: Translate operational onboarding and maintenance needs into scalable technical workflows that improve delivery speed, consistency, and quality across customer environments, including provisioning, secure channel establishment, validation, monitoring, and sustainment.
• Security by Design: Build automation and infrastructure patterns that align with zero-trust principles, network segmentation requirements, access controls, and critical infrastructure security expectations.
• Technical Design & Problem Solving: Break down ambiguous infrastructure and workflow problems into clear technical designs, implementation plans, and well-scoped engineering tasks.
• Engineering Standards: Produce clear design documentation, implementation guidance, and operational handoff materials. Help reinforce strong standards for code quality, testing, and maintainability within the team’s Connectivity engineering work.
• Elevate the Team: Provide thoughtful code reviews, mentor junior and mid-level engineers, and help grow the team’s software-driven approach to Connectivity engineering.

What You Bring

Required Qualifications:

• Experience: 5+ years of experience building infrastructure, automation, or platform engineering solutions in complex environments.
• Automation Development: Strong experience building infrastructure automation and tooling using disciplined engineering practices such as Git workflows, structured configuration data, CI/CD pipelines, testing, and code reviews.
• Linux Expertise: Strong hands-on experience with Linux operating systems, system configuration, package and service management, debugging, and scripting.
• Networking Knowledge: Solid understanding of network design, segmentation, VPNs, firewalls, encryption, and secure connectivity patterns.
• Technical Leadership: Proven ability to independently solve ambiguous technical problems within a complex platform or infrastructure domain, drive solution design through implementation, communicate tradeoffs clearly, and support the growth of less experienced engineers.
• Travel: Ability to travel quarterly for Program Management Reviews and team collaboration.

Preferred Qualifications:

• Strongly prefer candidates residing in the Denver, CO metro area
• Prior experience working within DoD, Air Force, or Federal contractor environments.
• Relevant technical certifications such as CompTIA Network+, CompTIA Security+, CCNA, CCNP, CCIE, AWS Advanced Networking, etc.
• Experience with OT/ICS, critical infrastructure, industrial networks, facility-edge environments, and network automation tools (e.g., Ansible, Cisco DevNet, open-source routing tools).

What Success Looks Like (First 90 Days)

• 30 Days: Ramp up on existing connectivity architectures, automation tooling, lab environments, and onboarding workflows, and build relationships across Connectivity Operations, Platform, and adjacent engineering teams.
• 60 Days: Contribute code and design improvements to active automation and infrastructure workflows, identify where provisioning, configuration, and validation can be standardized, and begin shaping implementation plans for a complex workflow or tooling area.
• 90 Days: Independently own a tooling or automation area within Connectivity, deliver production-ready improvements that increase repeatability and reduce operational friction, and mentor teammates through code reviews, design reviews, and implementation guidance.
