Email Security Engineer

The Email Security Engineer will provide hands-on technical support and security engineering services across Select’s customer portfolio.

This is a customer-facing engineering position. You will investigate technical issues, administer and optimize email security environments, evaluate security configurations, recommend improvements, document findings, and help customers strengthen their overall email security posture.

We don’t expect the successful candidate to know everything on day one. We place significant value on technical aptitude, communication, curiosity, ownership, judgment, and the ability to follow an issue through to completion.

For candidates with greater experience, there is significant opportunity to assume broader technical responsibility and help shape Select’s engineering practices as the company grows.

Responsibilities

• Provide technical engineering support across Select customer environments
• Administer, troubleshoot, and optimize email security configurations
• Investigate technical issues and drive them through resolution
• Participate in customer meetings and communicate technical concepts clearly
• Conduct and support Select Best Practice Assessments (BPAs)
• Identify configuration weaknesses, security risks, and opportunities for improvement
• Document technical findings, recommendations, remediation activities, and customer environments
• Assist with customer onboarding and technical transitions
• Collaborate with other engineers to provide backup coverage and share technical knowledge
• Proactively escalate technical or customer concerns when appropriate
• Contribute to engineering documentation, methodology, and internal knowledge
• Help improve the tools and processes Select uses to deliver customer engineering services

Experience with some of the following is preferred:

• Mimecast administration and troubleshooting
• Microsoft 365 and Exchange Online
• Secure Email Gateways
• Email routing and mail-flow troubleshooting
• DNS
• DMARC, SPF, and DKIM
• Email authentication and anti-spoofing technologies
• Security incident investigation
• Microsoft Entra ID and identity concepts
• General networking and cybersecurity fundamentals

Direct Mimecast experience is highly desirable but not required for an otherwise strong candidate.

What We’re Looking For

We’re looking for someone who combines technical ability with strong professional habits.

The successful candidate should demonstrate:

• Excellent written and verbal communication
• Professionalism when working directly with customers
• Strong troubleshooting and analytical skills
• Curiosity and a desire to understand how and why systems work
• Ownership of assigned work and consistent follow-through
• Reliability and responsiveness
• Strong organizational and documentation habits
• Comfort working independently and collaboratively in a growing company
• Willingness to ask questions, learn from others, and share knowledge
• Sound judgment and an understanding of when an issue should be escalated

Education & Certifications

We welcome candidates from different educational and professional backgrounds.

A degree in cybersecurity, computer science, information technology, engineering, or a related discipline is helpful but not required.

Relevant certifications such as CompTIA Security+, Network+, Microsoft certifications, or Mimecast certifications are desirable. Equivalent hands-on experience will be considered.

• Flexible schedule
