Position Overview

We are seeking a Security-Focused DevOps Engineer to lead the packaging, deployment, and security posture of a critical software suite used in fire prevention systems.

This role sits at the intersection of DevOps, cybersecurity, and software deployment within an ecosystem that includes:

• A Windows-based configuration application;
• A C/C++ Linux simulation of a fire prevention panel;
• A C++/Qt simulator interacting with live simulations and configuration files.

The successful candidate will be responsible for delivering a seamless, secure, and enterprise-ready deployment experience. This includes packaging and integrating Linux components for Windows environments using WSL2, virtual machines, or containers, as well as implementing an Okta-based identity management solution across the software suite.

Key Responsibilities

• Design, package, and deploy software solutions across Windows and Linux environments.
• Implement and maintain secure deployment processes and operational practices.
• Package and distribute Linux components for Windows users through WSL2, virtualization, or container technologies.
• Implement and administer identity and access management (IAM) solutions using Okta or an equivalent identity platform.
• Integrate authentication and authorization mechanisms using SAML, OAuth2, OIDC, and JWT standards.
• Perform vulnerability assessments, security reviews, and system hardening activities.
• Apply security best practices across infrastructure and deployment environments.
• Collaborate with development teams to ensure secure software delivery practices are followed.
• Troubleshoot deployment, integration, and security-related issues across the software ecosystem.
• Produce and maintain clear deployment, security, and operational documentation for internal teams and enterprise customers.
• Ensure compliance with reliability, security, and corporate customer requirements.

Required Qualifications

• Minimum 5 years of hands-on DevOps experience with a strong security focus.
• Demonstrated experience packaging and deploying software in enterprise environments, primarily Windows-based.
• Strong expertise in Linux environments and Windows/Linux integration.
• Solid experience with WSL2, Docker, Podman, or other container technologies.
• Practical experience with Okta or a comparable identity provider.
• Good knowledge of:
• SAML
• OAuth2
• OpenID Connect (OIDC)
• JWT

Proficiency in:

• C++
• Bash
• HTTP
• JSON
• TLS/SSL
• Experience with vulnerability management, system hardening, and secure software delivery practices.
• Excellent communication, documentation, and organizational skills.

Preferred Qualifications

• Experience in hybrid Windows/Linux enterprise environments.
• Knowledge of enterprise software packaging and deployment tools.
• Experience working in regulated or security-sensitive industries.
• Familiarity with industrial systems, fire prevention systems, or other mission-critical software environments.

Desired Profile

• Ability to work autonomously across both Windows and Linux environments.
• Proactive, security-first mindset with strong ownership of deliverables.
• Comfortable owning the full DevOps and security lifecycle with minimal supervision.Generalist profile with deep security expertise, rather than a purely DevOps or purely cybersecurity background.
