About the Company

ADDA is partnering with a fast-growing, high-performing IT Managed Service Provider (MSP) serving clients across diverse industries. The organization is known for its commitment to exceptional client service, a collaborative team culture, and a modern, non-tiered engineering model where every team member is empowered to solve problems end-to-end.

Were looking for a Systems Support Engineer who thrives in dynamic environments, enjoys tackling complex challenges, and wants meaningful ownership over their work.

The Role

As a Systems Support Engineer, youll work across multiple client environments to troubleshoot issues, implement solutions, and support ongoing technical improvements. This is not a traditional ticket churn support role youll work directly with clients, drive root-cause fixes, contribute to projects, and help shape how the MSP operates.

Youll get exposure to a wide range of technologies across infrastructure, cloud services, networking, cybersecurity, and automation. If you like variety, autonomy, and learning something new every day, this role offers that and more.

What Youll Do

• Diagnose and resolve advanced technical issues across Windows, macOS, Linux, Microsoft 365, Google Workspace, and various cloud and on-prem environments.
• Support networking components including switches, firewalls, VPNs, VLANs, DNS/DHCP, Wi-Fi, and routing.
• Own issues from start to finish triage, investigation, solution, documentation, and communication.
• Collaborate with peers in a non-tiered engineering structure where knowledge sharing and equal contribution are core values.
• Participate in client-facing project work, including migrations, deployments, security implementations, and system upgrades.
• Identify repetitive tasks or patterns and propose automation, self-service, or process improvements.
• Maintain accurate documentation and contribute to an internal knowledge base that supports scalable solutions.
• Provide onsite support to NYC-area clients as needed.

What Were Looking For

• 13+ years of experience in an MSP or fast-paced, multi-client IT environment.
• Strong troubleshooting skills across systems, networking, cloud services, and security fundamentals.
• Ability to diagnose unfamiliar technologies through logical analysis, research, and experimentation.
• Clear communication skills with both technical and non-technical users.
• A proactive mindset you automate, simplify, or eliminate repetitive tasks whenever possible.
• A hunger to learn new technologies and continuously build your skill set.
• Certifications (Microsoft, Cisco, CompTIA, etc.) are a plus but not required.

Why Youll Love Working Here

• Non-tiered engineering team: Everyone owns solutions end-to-end no escalations, no silos.
• Variety & exposure: Support dozens of environments and technologies, keeping your work interesting and skills growing fast.
• Professional growth: Mentorship, certification support, and hands-on project work accelerate your career.
• Impact: Your ideas for automation, efficiency, and client improvement are expected and implemented.
