Job description

The Senior IT Infrastructure Engineer is responsible for the design, engineering, implementation, deployment, documentation, testing, and ongoing capacity planning of infrastructure solutions such as hardware, software, and systems configuration solutions.

The individual in this role is expected to think strategically, drive long‑term infrastructure improvements, influence technical roadmap decisions, and handle critical, company‑wide outages. A key responsibility involves serving as a mentor and coach, guiding our junior engineers through direct training and technical leadership.

Your Day to Day

• System Reliability & Architecture: Design, build, and maintain highly available and scalable distributed systems. Define Service Level Indicators (SLIs) and Service Level Objectives (SLOs) to measure and ensure system health.

• Release Engineering & CI/CD Pipelines: Architect and optimize end‑to‑end CI/CD pipelines to ensure rapid, safe, and repeatable software delivery.

• Automation & Engineering: Reduce manual, repetitive work by writing code and automation scripts using languages such as Python, PowerShell, or Java to improve efficiency and system reliability.

• Advanced Problem Solving: Exceptional analytical skills with the ability to correlate and troubleshoot complex issues across diverse platforms. Serves as the final point of escalation for high‑impact technical challenges, utilizing command‑line mastery and interactive shells to resolve deep‑system anomalies.

• Infrastructure & Platform Engineering: Serve as the technical lead for hybrid infrastructure, managing the full lifecycle of on‑prem and cloud‑based resources.

• Monitoring & Observability: Develop the strategic roadmap for monitoring and observability across the hybrid environment.

• Capacity Planning & Performance: Analyze system resource usage to forecast and manage capacity, ensuring systems handle traffic growth.

• Mentorship & Leadership: Mentor junior team members, conduct code reviews, and promote SRE best practices across the organization.

• Security & Compliance: Maintains a high‑security baseline for all platform services, ensuring compliance with SOC 2, PCI-DSS, or CIS Benchmarks where applicable. Conducts regular security audits, manages encryption protocols, and ensures adherence to the principle of least privilege.

Strong proficiency in networking fundamentals (TCP/IP, routing, DNS, VPN, SMTP).

• Experience in security practices (SSL/TLS, SSH, encryption, LDAP). Experience implementing configuration management tools (Chef, Ansible). Design and build experience in orchestration using Cloudbolt or Rundeck.

• Expertise in building and maintaining code‑driven infrastructure using Terraform for provisioning, combined with Python, Shell, and PowerShell for advanced scripting and operational automation.

• Experience evaluating and integrating AI‑driven tools into existing IT infrastructure workflows to optimize operational efficiency and enhance automated processes.

• Proven ability to lead infrastructure projects from design through deployment.

• Experience building and managing physical infrastructure in on‑prem or hybrid environments. Experience providing technical guidance to external vendors and partners.

• Ability to communicate complex technical concepts to both technical and non‑technical audiences. Excellent documentation and mentoring skills.

• Create and update technical documentation, standards, and procedures to support consistency and knowledge sharing.
