Role Overview

As the Head of Managed Services at ThingsBoard, you will be the founder and leader of our new Private Cloud department. This is a critical business unit where the "Product" is the seamless operation, performance, and reliability of ThingsBoard instances in the cloud. You will lead a team of Customer Reliability Engineers (CREs) and Technical Account Managers (TAMs) to ensure that our largest customers receive a premium, "zero-friction" experience.

Key Responsibilities

1. Team Leadership & Motivation

• Build the Culture: Foster a "CRE mindset" where engineers are motivated to automate repetitive tasks and take pride in 99.9% uptime.
• Mentorship: Conduct 1-on-1s, identify skill gaps, and provide the team with the tools (including AI-driven automation) they need to succeed.
• Resource Management: Manage the hiring roadmap and on-call rotations to ensure 24/7 coverage without team burnout.

2. Process Ownership & Maintenance

• The Playbook: Design and maintain the internal "Standard Operating Procedures" (SOPs) for deployment, patching, and incident response.
• SLA Enforcement: Define and monitor Service Level Agreements (SLAs). You are responsible for ensuring we meet our promises to the customer.
• Operational Excellence: Ensure every technical fix is documented in the Internal Knowledge Base to prevent recurring issues.

3. Strategic Customer Management ("Know Your Customer")

• Usage Insights: Deeply understand how our customers use ThingsBoard (device counts, data frequency) to anticipate scaling needs.
• Voice of the Customer: Act as the internal advocate for Private Cloud clients, providing feedback to the core Product team on how to make the platform more "manageable."

• Architecture Mindset: Ability to understand the ThingsBoard stack and how it interacts with different cloud provider services.

Leadership & Soft Skills

• Conflict Resolution: You are the calm in the storm. Whether it’s a heated discussion between Sales and Engineering or a frustrated customer during an outage, you find the "Win-Win" solution.
• Proactive Problem Solving: You don't wait for a ticket to be filed. You see a bottleneck in the onboarding process and fix it before the next customer arrives.
