About M365Consult

M365Consult is a fast-growing European startup specializing in Microsoft solutions. The team is passionate about innovation, collaboration, and building a strong brand presence across digital platforms, and is looking for motivated experts eager to learn and grow with us.

Role Overview

M365Consult is seeking a highly proficient Microsoft Exchange On-Prem Administrator for a long-term full-time contract. You will work for an MSP environment supporting around 10 customers, focusing primarily on on-premises Exchange within hybrid configurations. Approximately 50% of your time will be dedicated to server hardening and upgrades, and the remaining 50% to project work, troubleshooting, and ticket handling.

The onboarding phase will last about 2 weeks at 3 hours per day, followed by a ramp-up to 4-6 hours daily, then to a regular 8 hours per day. Work will be performed during US time zones for non‑English-speaking customers, so you must be comfortable using translation tools in day-to-day work. This role is reserved for true experts; deep technical interviews will be conducted before hiring and throughout onboarding.

Key Responsibilities

• Configure, manage, and maintain Microsoft Exchange servers and related infrastructure, including upgrades, patching, hardening, and performance optimization.
• Troubleshoot and resolve Exchange issues such as mail flow disruptions, database problems, and client connectivity errors.
• Work extensively with hybrid Exchange configurations, with a strong focus on the on‑premises side.
• Perform ongoing server hardening and security improvements across multiple customer environments.
• Handle project-based tasks as well as daily troubleshooting and ticket resolution for approximately 10 MSP customers.
• Utilize and manage Edge Servers and email security gateways such as EOP, Proofpoint, OPEN Mission Control, and similar tools.
• Collaborate with distributed teams while working in a primarily non‑English environment, using translation tools where needed.

Requirements

• Proven, senior-level experience as a Microsoft Exchange On-Prem Administrator, ideally in an MSP or multi-tenant environment.
• Deep hands-on expertise with Exchange Server (on-prem), including hybrid deployments.
• Strong track record in server hardening, upgrades, patching, and performance tuning.
• Solid experience troubleshooting mail flow, databases, and client connectivity.
• Practical knowledge of Edge Servers and email security gateways (EOP, Proofpoint, OPEN Mission Control, etc.).
• Comfortable working long-term in US time zones with non‑English-speaking customers.
• Ability to pass demanding, in-depth technical interviews and ongoing technical evaluations.

What We Offer

• Long-term, full-time contract with phased onboarding and ramp-up.
• Work in a deeply technical environment with real expert-level peers.
• Opportunity to shape and secure complex Exchange and hybrid environments across multiple customers.
• Fully remote work with structured onboarding and clear growth in hours and responsibility.

How to Apply

Submit your CV and a short cover letter outlining your Exchange On-Prem and hybrid experience, including examples of hardening, upgrades, and complex troubleshooting you have led.
