Senior Infrastructure & Security Engineer

Memphis, TN

Do you like working with different project teams in a fast-paced environment? Are you interested in joining an organization focused on making a positive impact? If so, we’d like to talk with you about growing with us.

EnSafe is accepting applications for a full-time Senior Infrastructure & Security Engineer to join our IT team in Memphis, TN. This position will support all EnSafe offices across the U.S. and Canada.

The successful candidate must be willing to work onsite at the Memphis, TN, EnSafe Headquarters campus. Relocation assistance is available to meet this expectation.

What we are looking for

We are seeking a senior, hands‑on technology professional who enjoys balancing infrastructure, security, and compliance responsibilities in a collaborative environment. This role serves as the lead technical resource for infrastructure and security operations, working closely with our Director of IT to support and enhance the systems that keep our business running securely and efficiently.

The ideal candidate is a versatile problem-solver who is equally comfortable troubleshooting core infrastructure, strengthening security controls, and contributing to compliance initiatives. Rather than viewing infrastructure and cybersecurity as separate disciplines, they understand how the two work together to support a secure, reliable technology environment.

Our IT team supports a regulated environment that includes federal contract work governed by frameworks such as CMMC and DFARS. This is an opportunity to play a meaningful role in maintaining and advancing systems that directly support important projects and clients. Because our team is lean and highly collaborative, your contributions will be visible, valued, and impactful. We are looking for someone who takes pride in building solutions that are thoughtful, reliable, and designed to meet both operational and compliance requirements.

Joining our team means immersing yourself in an environment that nurtures creativity, encourages collaboration at all levels, fosters a supportive culture, and facilitates professional development.

• Own infrastructure operations across servers, storage, Active Directory, Entra , Microsoft Azure, and on‑prem identity.
• Run the security operations stack day to day, including Crowd Strike Falcon (EDR), Sumo Logic (SIEM), Microsoft Defender, Microsoft Purview, and endpoint protection tooling.
• Manage and tune vulnerability management, alert triage, and incident response workflows in coordination with the Director of IT.
• Support the implementation, maintenance, and technical operation of security controls required by EnSafe’s CMMC and NIST compliance programs. Governance, risk management, policy ownership, and assessment management remain the responsibility of the Director of IT.
• Lead infrastructure and security projects end‑to‑end, from requirements through implementation and documentation.
• Manage vendor relationships for infrastructure and security platforms, including renewals, contract review with EnSafe’s contracting team, escalations, and ongoing performance.
• Contribute to EnSafe’s AI governance work as part of a cross‑functional team. Not the owner of that program; an active participant.

• 9 or more years of progressively responsible IT experience, with at least three years in a role that combines infrastructure ownership and enterprise security.
• Hands‑on EDR operations experience, ideally Crowd Strike Falcon.
• Hands‑on SIEM operations experience, ideally Sumo Logic.
• Working knowledge of NIST SP 800‑171 and 800‑53, including knowledge of CMMC Level 2 and DFARS.
• Working network competence - enough to support Fortinet, VPN, segmentation, and basic firewall work during the gap before a dedicated Senior Network Engineer joins the team.
• Scripting fluency in Power Shell, Python, or both.
• Security+, Network+, or a Microsoft equivalent certification.
• Strong written and verbal communication – the ability to translate technical work for non‑technical stakeholders, and the willingness to do it.
