In this role, you will own ambiguous technical problems within the Connectivity engineering domain, drive solutions from design through implementation, and help less experienced engineers deliver with quality and consistency., * 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., * Safety & Innovation: You embed security and reliability practices into daily work to drive continuous improvement and mitigate risk.
• People & Communication: You invite vigorous debate and offer "kindly blunt" feedback, always maintaining empathy and assuming noble intent.
• Integrity & Ethics: You build trust by honoring commitments, acting ethically, and resolving conflict through direct, honest communication.
• Strategic Problem Solving: You focus on high-priority issues to create documented, and scalable solutions-avoiding shortcuts.
• Agility: You move quickly to fix small problems, learn from the past, and pivot transparently when the mission requires it.

Do you have experience in Team leadership?, * 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., * Must be a U.S. Citizen and able to obtain a DoD NIPR network account and Common Access Card (CAC)
• Must have, or be able to obtain, a Secret Clearance

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., At Simplesense, we value high-trust autonomy. We look for people who can navigate ambiguity and are driven by the mission.
