This is a long-term consulting opportunity for someone who enjoys solving complex technical problems, mentoring experienced engineers, and working in challenging enterprise environments. This Is Not a Typical Exchange Administrator Position We are not looking for someone to perform routine Exchange administration or primarily manage Microsoft 365. We are looking for the person experienced Exchange engineers call when they have exhausted normal troubleshooting methods.

About the Engagement This is an independent contractor position. Work is assigned as needed and may include: * Architecture reviews * Escalated troubleshooting * Project consulting * Exchange upgrades and migrations * Disaster recovery * Production incident response * Knowledge transfer and mentoring Most work is performed remotely during Eastern Time business hours, with occasional evening or weekend maintenance. ## Related Videos - [This Is Not Your Father's .NET](https://www.wearedevelopers.com/videos/967-this-is-not-your-father-s-net) - [gRPC Load Balancing Deep Dive](https://www.wearedevelopers.com/videos/1576-grpc-load-balancing-deep-dive) - [Develop enterprise-ready applications for Microsoft Teams with Azure resources on modern web technologies](https://www.wearedevelopers.com/videos/187-develop-enterprise-ready-applications-for-microsoft-teams-with-azure-resources-on-modern-web-technologies) - [Introducing Digital Samba Embedded Video Conferencing API MCP Server](https://www.wearedevelopers.com/videos/1640-introducing-digital-samba-embedded-video-conferencing-api-mcp-server) - [Cloud Run- the rise of serverless and containerization](https://www.wearedevelopers.com/videos/106-cloud-run-the-rise-of-serverless-and-containerization) - [Don’t shoot yourself in the foot.](https://www.wearedevelopers.com/videos/580-don-t-shoot-yourself-in-the-foot) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Tips on mastering remote job interviews](https://www.wearedevelopers.com/magazine/23-tips-on-mastering-remote-job-interviews) - [How to Answer the “Why Should We Hire You” Interview Question](https://www.wearedevelopers.com/magazine/321-how-to-answer-the-why-should-we-hire-you-interview-question) - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges) - [Promotion Interview Questions: How to Answer and Get the Job](https://www.wearedevelopers.com/magazine/413-promotion-interview-questions-how-to-answer-and-get-the-job) - [How to Answer the Interview Question: “Why Do You Want to Be a Software Engineer?”](https://www.wearedevelopers.com/magazine/392-how-to-answer-the-interview-question-why-do-you-want-to-be-a-software-engineer)
