Full Job Description
Senior Infrastructure Engineer

We are seeking a Senior Infrastructure Engineer who can bridge traditional enterprise infrastructure with modern software development and AI-driven automation.

This is a unique hybrid role requiring someone who is equally comfortable working within cloud and enterprise infrastructure environments and building applications, integrations, and automation solutions.

The ideal candidate is technically hands-on, collaborative, curious, and willing to jump into complex problems across infrastructure, systems, development, and emerging AI technologies.

Key Responsibilities

Infrastructure & Cloud Engineering
  • Administer and support Windows, Windows Server, and macOS environments.
  • Manage Microsoft Azure and Entra ID environments.
  • Support identity, authentication, permissions, and Group Policy.
  • Manage endpoint environments using technologies such as Microsoft Intune or similar platforms.
  • Support cloud and hybrid infrastructure environments.
  • Troubleshoot and maintain VPNs, firewalls, DNS, DHCP, and VLANs.
  • Support complex infrastructure issues and escalations.
  • Assist with infrastructure assessments, remediation, and optimization initiatives.
  • Develop PowerShell scripts and automation workflows to improve IT operations.

Application Development
  • Design and build internal web applications and automation tools.
  • Develop modern front-end applications using technologies such as React, JavaScript, HTML, and CSS frameworks.
  • Build and deploy applications using Azure App Services.
  • Manage application data and storage using Azure Blob Storage.
  • Implement secure application authentication using OAuth and Entra ID.
  • Develop backend functionality and integrations as needed.
  • Full-stack development experience is highly preferred.

AI & Intelligent Automation
  • Build and support AI-enabled applications and automation solutions.
  • Integrate LLM APIs and AI capabilities into internal applications.
  • Develop AI-powered functionality such as intelligent search, summarization, conversational interfaces, and workflow automation.
  • Build and maintain Model Context Protocol (MCP) servers.
  • Develop custom REST APIs and API connectors to integrate systems, applications, data sources, and AI tools.
  • Support the development of AI agents and automated workflows.
  • Apply appropriate security, logging, governance, and human oversight to AI-driven solutions.

Systems Integration & Automation
  • Identify opportunities to automate repetitive infrastructure and support processes.
  • Build integrations between internal and third-party platforms.
  • Troubleshoot complex application and infrastructure issues.
  • Develop tools that improve operational efficiency and reduce manual processes.
  • Partner with technical teams to improve system reliability, scalability, and automation.

Required Qualifications
  • 7+ years of IT infrastructure experience.
  • 3+ years of experience building and deploying web applications.
  • Strong experience with Microsoft Azure and enterprise infrastructure.
  • Experience with React, JavaScript (ES6+), HTML5, or comparable modern front-end technologies.
  • Experience deploying applications through Azure App Services.
  • Experience with Azure Blob Storage or similar cloud storage technologies.
  • Strong understanding of OAuth and Entra ID authentication.
  • Strong knowledge of enterprise networking, including VPNs, firewalls, DNS, DHCP, and VLANs.
  • Experience with Windows Server and enterprise endpoint environments.
  • Experience developing scripts and automation, particularly PowerShell.
  • Experience developing APIs, system integrations, or custom connectors.
  • Strong troubleshooting and root-cause analysis capabilities.

AI & Integration Experience

Candidates should have experience with, exposure to, or the technical ability to quickly develop expertise in:
  • AI/LLM application development
  • Integrating LLM APIs into applications
  • AI agents and intelligent automation
  • Model Context Protocol (MCP)
  • MCP servers
  • REST APIs and custom API connectors
  • Connecting AI tools with enterprise systems and data sources

Hands-on production AI experience is highly valued; however, candidates with strong application development and integration backgrounds who can demonstrate the ability to quickly learn and build within emerging AI technologies may also be considered.

Preferred Qualifications
  • Full-stack application development experience.
  • Experience with AWS in addition to Azure.
  • Experience working within complex or regulated enterprise environments.
  • Experience supporting security and compliance initiatives.
  • Experience automating traditional infrastructure or IT support functions using AI.
  • Experience working across infrastructure, application development, cloud, and security teams.

Ideal Candidate

This role is best suited for someone who does not fit exclusively into a traditional Systems Administrator, DevOps Engineer, or Software Engineer profile.

We are looking for a technically versatile engineer who brings strong enterprise infrastructure experience but can also write code, build applications, develop integrations, and work with AI technologies.

The right person will be collaborative, team-oriented, technically curious, comfortable being challenged, and willing to jump into whatever technical problem needs to be solved.
