Senior Cloud Architect

About BITSUMMIT

BITSUMMIT is a fast-growing technology consultancy specializing in cloud infrastructure, managed services, and enterprise IT solutions. As we scale, we build our team with people who take ownership, operate with precision, and care about doing the work right.

About the Opportunity

We are hiring a Senior Cloud Architect to lead the design and execution of multi-cloud infrastructure programs across AWS and Azure. Reporting to the Director of CloudOps, you will be the senior technical voice on the team.

You will own architecture for high-impact 2026 initiatives: Terraform-driven environment segregation, an organisation-wide automated patching program, and a major Amazon Linux end-of-life remediation.

This is not a pure architecture seat. The role demands someone who can take a vague or unscoped problem, decompose it technically, and execute it. You will spend equal time at the whiteboard and in the terminal.

What you will do

• Design and lead Terraform / OpenTofu work to refactor existing AWS and Azure resources into properly segregated environments, with clear network and security boundaries
• Architect and roll out a Patch Manager program that automatically patches OS and middleware across every application running in AWS and Azure, including automatic vulnerability remediation
• Lead the Amazon Linux end-of-life remediation across the cloud estate, including planning, scheduling, and execution
• Design site-to-site VPN connectivity and other networking integrations between corporate and cloud environments
• Set the standards bar across CloudOps disciplines: cloud security, networking, CDN, scalability, reliability, and incident management
• Take ownership of unscoped or discovery-phase work, define the technical path forward, and drive it to closure
• Pair locally with the existing CloudOps engineering bench to mentor and uplift the team, including another senior engineer joining the Canadian office

Required Experience

• Demonstrated, hands-on track record designing and implementing production cloud architecture on AWS (primary requirement). Azure experience strongly preferred.
• Hands-on, production experience implementing cloud solutions with Terraform or OpenTofu for infrastructure-as-code
• Senior-level architectural maturity: ability to take an ambiguous requirement, break it down technically, and execute independently without prescriptive direction
• Broad fluency across cloud standards: security, networking, CDN, scalability, reliability, and incident management
• Strong written and verbal communication; comfortable presenting designs to engineering leadership and influencing direction

Nice to Have

• Site-to-site VPN and enterprise network design experience at scale
• Hands-on experience with patch management at scale (AWS Systems Manager Patch Manager, Azure Update Manager, or comparable tooling)
• Amazon Linux 2 end-of-life migration or Linux LTS remediation experience
• Experience leading unscoped or discovery-driven projects to delivery
• Mentoring or technical leadership experience with mid-level engineers

Working Arrangement

Engagement type: Contract, with potential for extension or conversion to full-time.

Time zone: Eastern Time. Full-time, approximately 40 hours per week.
