Senior Security Engineer
Houston, TX (Westchase Area) | Hybrid | Full-Time | Must Live in the Houston Area
iSphere is looking for a Senior Security Engineer who enjoys building security solutions, improving security posture, and occasionally explaining to people why "we've always done it this way" isn't actually a security strategy.
This is a hands-on engineering role supporting a mid-sized enterprise environment. The team needs someone who can move comfortably between identity, endpoint, network, application, and infrastructure security while helping design and implement security controls that actually work in production environments.
This is not a security analyst position. This is for someone who likes building, configuring, integrating, hardening, automating, troubleshooting, and improving security technologies across the enterprise.
You'll work closely with infrastructure, networking, development, and operations teams to strengthen security controls, support ongoing initiatives, and help drive continuous improvement across the security program.
What they're really looking for:
• Strong Microsoft security engineering experience including Entra ID, Defender XDR, Intune, and Purview
• Experience implementing and supporting Privileged Identity Management (PIM)
• Hands-on CyberArk engineering experience including vault architecture, onboarding, session management, integrations, and high availability
• Experience designing and supporting enterprise PKI environments and certificate lifecycle management
• Strong experience with F5 BIG-IP LTM and Advanced WAF technologies
• Experience with Cisco Secure Access and enterprise network security architectures
• Strong Active Directory and Windows infrastructure security background
• Knowledge of authentication, identity, and access management technologies
• VMware infrastructure experience
• Experience with threat hunting, incident response, root cause analysis, and remediation efforts
• Understanding of application security, API security, authentication, authorization, and secure development practices
Experience with NIST, ISO 27002, enterprise security controls, and governance frameworks is also highly valuable.
This role will spend time engineering new capabilities, improving existing controls, supporting security operations, and helping ensure security is built into infrastructure and applications instead of bolted on afterward when everybody suddenly discovers a problem.
The right person for this role is naturally curious, technically deep, and comfortable getting pulled into everything from certificate issues and identity problems to network security architecture and incident investigations. Somebody who can troubleshoot complex issues, explain solutions clearly, and isn't afraid to ask, "Why are we doing it this way?" when the answer matters.
If you've spent your career working across multiple security disciplines and enjoy being the person people call when the problem is bigger than a single tool, this one is worth a look.

Lewisville, TX | Onsite | 12+ Month Contract
iSphere is looking for an Enterprise Applications Training Specialist who believes the best training doesn't end with, "Any questions?" It ends with people actually feeling confident enough to use the software.
This role is a great fit for someone who enjoys teaching just as much as they enjoy technology. You'll help roll out enterprise applications across the district by creating engaging training materials, producing instructional videos, leading both in-person and virtual training sessions, and serving as a trusted resource for users long after implementation.
If you've ever been the person everyone comes to because you can explain complicated software without making people feel complicated, you'll probably enjoy this one.
What they're really looking for:
• Bachelor's degree required (teaching certification is a plus)
• 4+ years of experience in software training, instructional design, technical documentation, or a related field
• Experience delivering instructor-led and virtual software training
• Strong technical writing and documentation skills
• Experience creating online learning content and training materials
• Video production and editing experience from concept through final delivery
• Familiarity with learning management systems such as Canvas
• Experience supporting enterprise applications such as Skyward, Kronos, ERP, SIS, or similar platforms
• Excellent communication, organization, and customer service skills
You'll spend your time:
• Designing training programs and curriculum for enterprise software implementations
• Creating user guides, documentation, quick reference materials, and video tutorials
• Delivering engaging training sessions for district staff
• Working with subject matter experts to turn technical knowledge into practical learning experiences
• Producing training videos from scripting and recording through editing and post-production
• Supporting technology implementations and enterprise application rollouts
• Assisting users with questions, troubleshooting, and technology support tickets
• Evaluating new training tools, technologies, and creative ways to improve learning
The right person for this role enjoys helping others succeed. They're comfortable standing in front of a classroom one day, editing a training video the next, and rewriting a user guide because they know there's a simpler way to explain it.
Around here, good training isn't measured by how many slides you presented. It's measured by how few help desk tickets show up afterward.
If you're passionate about technology, enjoy teaching, and like turning "I have no idea how this works" into "I've got it," we'd love to talk with you.
