## 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

### Internal Notes for Recruiters (Optional to Share)

Target candidates with infrastructure + networking + IoT exposure, not desktop or pure Windows admins

Hands-on device experience is mandatory for NYC & London

Strong enterprise mindset (security, documentation, change control) is critical

1. Strong experience with Windows and Linux server engineering

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