Senior Remote Integration Engineer Jobs in Colorado

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

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.

As our Senior Infrastructure Automation Engineer, you will play a critical role in securely and efficiently onboarding customer facilities into our hybrid-cloud platform services. You will design and implement scalable infrastructure automation, configuration-driven tooling, Linux systems, and network infrastructure workflows that make deployment and lifecycle management across customer environments repeatable, secure, and efficient. You will partner closely with the Connectivity and broader engineering teams to automate the provisioning, configuration, validation, maintenance, and sustainment of infrastructure spanning facility-edge, on-premises, and cloud-connected environments.

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.

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

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.

• Infrastructure Automation & Infrastructure-as-Code: Lead the design and implementation of reusable tooling, configuration management, and network infrastructure-as-code workflows that automate the lifecycle of Connectivity network infrastructure across customer environments.
• Linux & Network Infrastructure: Develop and maintain automation for Linux-based systems and network appliances, including system bootstrapping, secure configuration generation, package and software management, network configuration, updates, and validation.
• Infrastructure Provisioning & Lifecycle: Translate facility onboarding and sustainment needs into scalable technical workflows that improve delivery speed, consistency, and quality, including infrastructure provisioning, secure connectivity, configuration management, validation, monitoring, upgrades, 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 and design reviews, mentor junior and mid-level engineers, and help grow the team's software-driven approach to provisioning and managing Connectivity network infrastructure.

• Experience: 5+ years of experience building infrastructure automation, systems engineering, network infrastructure, or platform engineering solutions in complex environments.
• Infrastructure Automation: Strong experience automating infrastructure provisioning, configuration, or lifecycle management using disciplined engineering practices such as Git workflows, structured configuration data, infrastructure-as-code or configuration management, CI/CD pipelines, testing, scripting, 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.

• Strongly prefer candidates residing in the Denver 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).

• 30 Days: Ramp up on existing infrastructure architectures, Linux and network systems, automation tooling, lab environments, and customer onboarding workflows, and build relationships across Connectivity Operations, Platform, and adjacent engineering teams.
• 60 Days: Contribute code and design improvements to active infrastructure automation workflows, identify opportunities to standardize provisioning, system configuration, network configuration, and validation, and begin shaping an implementation plan for a complex infrastructure tooling or lifecycle area.
• 90 Days: Independently own an infrastructure automation or lifecycle area within Connectivity, deliver production-ready improvements that make deployments more repeatable and reduce operational friction, and mentor teammates through code reviews, design reviews, and implementation guidance.

Pay Range: $155k-$195k per year. Compensation is determined based on experience, skill level, and location. We review ranges regularly to ensure market competitiveness.
