System engineer - Infra & IoT

Systems Engineer – Enterprise IoT & Infrastructure (L2–L3)

NYC, NY (Onsite – physical device handling required)

What are the top 3 skills required for this role?

1. Strong experience with Windows and Linux server engineering

2. Solid networking fundamentals, including Layer 3 concepts (routing, subnets, DNS, DHCP)

3. Hands on experience with IoT devices / hardware configuration and troubleshooting

## Role Overview
• We are seeking an experienced Systems Engineer with strong expertise in enterprise IoT infrastructure, server engineering, and networking to support and implement IoT/OT solutions for a global financial services environment.
• This is not a traditional Windows Administrator or L1 support role. The position requires L2 to early L3 technical depth, combining architectural understanding with hands‑on implementation, troubleshooting, and operational support across devices, networks, servers, SaaS platforms, and security frameworks.
• The role supports enterprise‑grade IoT deployments, including device configuration, patch testing, secure integrations, and rollout activities, while working closely with internal teams, vendors, and stakeholders.

## Key Responsibilities
• Support and implement enterprise IoT/OT device infrastructure, including configuration, maintenance, patching, and troubleshooting
• Translate architectural designs and requirements into operational and technical implementations
• Perform patch testing, deployments, and validation of devices and supporting infrastructure
• Troubleshoot complex issues across device, network, server, and platform layers
• Work with APIs, SaaS platforms, and hybrid cloud environments to enable secure integrations
• Support physical device handling, reformatting, and refurbishment (NYC & London roles) using defined documentation and procedures
• Collaborate with network, security, platform teams, and external vendors to resolve issues and support rollouts
• Create and maintain technical documentation, runbooks, and operational process guides
• Ensure compliance with enterprise security standards, including authentication, authorization, and encryption requirements
• Participate in migration, refurbishment, and new rollout projects for IoT platforms and devices

## Required Technical Skills
• Strong experience with Windows and Linux server engineering
• Solid networking fundamentals, including Layer 3 concepts (routing, subnets, DNS, DHCP)
• Hands‑on experience with IoT devices / hardware configuration and troubleshooting
• Working knowledge of APIs, system integrations, and technical environments
• Experience with SaaS platforms and enterprise authentication protocols (SAML, OIDC)
• Understanding of firewalls, proxy servers, and load balancers in enterprise environments
• Proven experience operating in L2 / early L3 support models
• Knowledge of security fundamentals, including encryption, authentication, and authorization

## Experience & Profile
• 4–8+ years of experience in Systems Engineering, Infrastructure Support, or IoT/OT environments
• Strong analytical and troubleshooting skills across multiple technology layers
• Ability to work independently while collaborating with global teams
• Comfortable supporting production enterprise environments with high security and reliability expectations

## Role Classification
• Level: L2 to early L3
• Focus Area: Enterprise IoT / OT Infrastructure (not end‑user support)
• Work Type: Combination of implementation, advanced support, and operational engineering
