At Red River Managed Services, we provide a welcoming and positive workplace where everyone feels valued and able to do their best work, fostering a one-team mentality. Our employees work together to foster wise decision-making that relies on data, experience, and collaboration. We seek self-motivated individuals who are open to an environment based on this teamwork and shared success.

We aim to expand our growing workforce with passionate individuals who are resilient in the face of uncertainty and possess a creative spirit, all while keeping the needs of our clients top of mind to foster individual and organizational success.

• Resilience — You thrive in rapidly changing circumstances; you adapt to change; you know when to include or elevate to others; you embrace a hard challenge.

The AWS Tier III Engineer is a senior infrastructure engineering and escalation role responsible for the support, design, implementation, troubleshooting, and optimization of complex client environments, with a primary focus on Amazon Web Services (AWS).

This position serves as a Tier III escalation point for complex technical issues that require advanced troubleshooting and engineering expertise beyond standard Tier I and Tier II support. The engineer will work directly with clients, internal engineering teams, vendors, and other technical resources to resolve critical issues, implement infrastructure improvements, and provide ongoing technical guidance.

While AWS is the primary area of specialization, this role requires broad infrastructure knowledge across networking, Windows/Linux systems, identity, security, backup, disaster recovery, virtualization, monitoring, and hybrid environments.

Ideal Candidate

The ideal candidate is a highly experienced infrastructure engineer who is comfortable operating independently in complex client environments and is capable of moving beyond traditional break/fix support.

The engineer should be able to take an issue from:

Escalation → Investigation → Root Cause → Remediation → Documentation → Preventative Improvement

The successful candidate will combine deep AWS technical knowledge with broad infrastructure expertise, strong communication skills, sound engineering judgment, and the ability to mentor other engineers.

This position is an AWS-focused Tier III infrastructure engineering role, rather than an AWS-only administration position. The engineer must be capable of troubleshooting across the complete technology stack when AWS workloads interact with networking, security, Windows/Linux systems, identity, backup, and on-premises infrastructure.

• Configure and troubleshoot AWS networking, including VPCs, subnets, routing, DNS, security groups, VPN connectivity, and hybrid connectivity.
• Manage and troubleshoot AWS IAM roles, policies, permissions, authentication, and authorization.
• Support AWS security controls and services and identify opportunities to improve the security posture of client environments.
• Design, implement, and troubleshoot AWS backup and disaster recovery solutions.
• Participate in disaster recovery planning, testing, documentation, and infrastructure resiliency initiatives.
• Monitor AWS environments and analyze CloudWatch, CloudTrail, VPC Flow Logs, operating-system logs, and application telemetry.
• Support AWS lifecycle management, including service upgrades, migrations, deprecated services, and end-of-support remediation.
• Assist with AWS migrations, modernization initiatives, and infrastructure projects.
• Develop automation using PowerShell, Python, Bash, AWS CLI, or similar technologies.
• Utilize Infrastructure as Code technologies such as Terraform, CloudFormation, or AWS CDK where appropriate.
• Identify repetitive operational processes and develop automation or standardized procedures to improve efficiency and consistency.
• Support hybrid environments integrating AWS with:
• Windows Server
• Linux
• Active Directory
• Microsoft Entra ID
• Microsoft 365
