Full job description

Overview:

The Principal Engineer, Cloud Engineering is a hands-on technical leader responsible for architecting, building, maintaining, and operating automated cloud infrastructure that power ICIMS products. This role includes Linux System Administration, Infrastructure-as-Code (IaC) using Terraform, and configuration management with Ansible across AWS. The Principal Systems Engineer sets best practices, mentors engineers, and partners with SRE, Security, and Product teams to deliver resilient, secure, and cost-efficient platforms at scale.

About Us:

ICIMS is a leading enterprise hiring platform that combines the scale and reliability of enterprise software with the transformative power of AI. Thousands of organizations across more than 200 countries and territories trust ICIMS to find and hire the people who shape their future and drive their business forward.

For more than 25 years, ICIMS has delivered end-to-end hiring solutions that improve recruiting efficiency, reduce costs and create exceptional candidate experiences.

ICIMS helps solve one of the biggest challenges businesses face today: building a workforce that can adapt, scale, and perform in an increasingly competitive and unpredictable talent market. We uniquely do that by combining enterprise-grade hiring technology, AI-powered insights and automation, and connected talent experiences to help organizations improve hiring outcomes while driving measurable impact.

Responsibilities:

Administer and maintain Linux servers across development, staging, and production environments
Perform OS hardening, patching, and security updates in compliance with organizational standards
Manage user accounts, permissions, and groups following least-privilege principles
Configure and maintain system services (e.g., SSH, NTP, DNS, logging) for reliability and security
Monitor system performance, troubleshoot issues, and optimize resource utilization
Implement automated configuration management using Ansible for consistency and drift prevention
Develop scripts (Bash/Python) to automate routine tasks such as log rotation, backups, and health checks
Collaborate with DevOps and SRE teams to integrate Linux systems into CI/CD pipelines
Infrastructure-as-Code development in Terraform and code reviews
Establish observability (logs, metrics, traces) and proactive alerting; drive SRE practices and incident response
Participate in on-call rotations; perform post-incident reviews and continual improvement
Collaborate with FinOps on right-sizing, capacity planning, and cost optimization

Security & Compliance Integration

Enforce OS-level security hardening standards (e.g., CIS benchmarks) across all Linux servers.
Support vulnerability management and automated patching processes
Ensure compliance with organizational security policies and regulatory requirements (SOC2, ISO27001)
Conduct periodic security reviews and participate in internal audits for Linux environments
Manage secure credential storage and rotation for system-level accounts and services

Qualifications:

Technical Expertise

7+ years in Linux administration and production support experience with on-calll responsibilities
5+ years of strong AWS experience and demonstrated knowledge
Expertise in Terraform and Ansible for configuration management
Hands-on experience with containers and orchestration (ECS/EKS)
Scripting skills in Bash and/or Python for automation and tooling
Solid understanding of networking (DNS, TLS, HTTP, routing, firewalls) and security fundamentals
Observability tooling experience
Some knowledge of Jenkins (administration, pipeline jobs, shared libraries)

Preferred:

Experience with AWS Organizations and multi-account governance
AWS professional-level certifications (e.g., Solutions Architect, DevOps Engineer)
Exposure to other database technologies or data platforms; MSSQL, MongoDB, MySQL
Exposure to other cloud technologies like Azure and GCP

Our approach helps us to build a winning team that represents a variety of backgrounds, perspectives, and abilities.
