4d • Hybrid

About The Position

Anderson Technologies is a family-founded IT consulting firm and Managed Service Provider (MSP) that has served small and mid-sized businesses in the St. Louis area and beyond for more than 30 years. We deliver end-to-end IT operations, cloud services, and cybersecurity, and we are known for creative, well-engineered solutions delivered with honesty and integrity. We are seeking a Solutions Architect / Tier 3 Engineer to serve as our highest point of technical escalation and the lead technical designer for client solutions. This is a hybrid architect-and-engineer role: you will resolve the complex, high-stakes issues that Tier 1 and Tier 2 cannot, while designing the cloud, network, and infrastructure solutions that underpin new projects, migrations, and client onboarding. Working closely with the VP of IT Operations, the service desk, and the project delivery team, you will own the technical depth of the practice — raising the standard of our support, strengthening how our projects are scoped and delivered, and mentoring the engineers around you. It is a role for a senior technologist who solves the hardest problems and makes everyone on the team better in the process.

Requirements

• Minimum 7 years in an MSP or IT services environment, with progressively greater technical responsibility.
• Deep, hands-on expertise administering Microsoft 365 and Microsoft Azure.
• Strong networking fundamentals: LAN/WAN, VPN, firewalls, DNS, and VoIP troubleshooting.
• Proven experience with tenant, email, and file-share migrations.
• Working proficiency with PSA and RMM tooling (e.g., Autotask, ConnectWise, Kaseya, NinjaOne, or Datto RMM) in a ticket-driven environment.
• Excellent root-cause troubleshooting and the discipline to resolve issues permanently.
• Clear, client-ready written and verbal communication, including the ability to explain technical concepts to non-technical stakeholders.

Nice To Haves

• Relevant certifications such as Microsoft Azure Administrator, Microsoft 365 Certified: Administrator Expert, CompTIA Network+ / Security+, or equivalent.
• Experience mentoring or coaching junior technicians or leading a technical workstream.
• Familiarity with backup / BCDR, security-awareness, and compliance platforms.
• Prior client-facing solution design or pre-sales engineering experience.

Responsibilities

• Serve as the final escalation point for the most complex service desk tickets that exceed Tier 1 and Tier 2 capability, including issues breaching SLA thresholds.
• Diagnose and permanently resolve Microsoft 365, Azure, networking, and connectivity issues, including business-critical outages affecting client internet and VoIP phone systems.
• Lead root-cause analysis to move recurring incidents from repeated break/fix to permanent remediation, and document fixes in the knowledge base.
• Identify patterns across escalations and recommend improvements to service desk processes, tooling, and standards that reduce ticket volume and speed resolution.
• Architect cloud, hybrid, and on-premises environments that are secure, resilient, and scalable to each client’s needs.
• Design Azure and Microsoft 365 environments with an emphasis on operational resilience, backup, and business continuity.
• Evaluate and recommend platforms, tools, and standards to be adopted across the client base.
• Provision and manage Azure subscriptions for client projects, including access control and cost visibility.
• Administer Microsoft 365 tenants, manage tenant-to-tenant migrations, resolve duplicate accounts, and manage licensing.
• Configure and maintain directory synchronization and identity across client tenants.
• Serve as technical lead for new client and end-user onboarding, ensuring clean cutover and data integrity.
• Lead file and data migrations and resolve sync and integration issues across platforms such as SharePoint, Egnyte, and mapped network drives.
• Partner with the project delivery team to translate designs into executable plans, guide resourcing and sequencing, and uphold scope, timeline, and quality standards throughout delivery.
• Provide technical oversight and quality assurance on project execution, stepping in to resolve technical roadblocks that put timelines at risk.
• Provide technical input and effort estimates for Statements of Work (SOWs) and IT assessments.
• Support sales engineering with hardware and software quotes, sizing, and vendor sourcing.
• Translate client requirements into accurate, deliverable technical scope.
• Manage and tune remote monitoring and management (RMM) and security alerting to reduce noise while catching real threats.
• Validate backups and disaster-recovery readiness across client environments.
• Establish and maintain runbooks, standard operating procedures, and configuration documentation that make both support and project delivery more consistent and repeatable.
• Model strong troubleshooting discipline and knowledge-sharing, serving as a go-to technical resource the team relies on.
• Champion continuous improvement — identifying bottlenecks across support and delivery workflows and driving practical fixes.
