cloudscaler - Principal Cloud Engineer AWS/Multiple

• SC clearance is required for our customer facing teams. You do not need active SC clearance as we will undertake checks upon you joining, but you must be eligible to pass SC clearance. DV clearance may be required for certain roles, so the ability/willingness to pass DV clearance is advantageous but not essential. • We hire for platform and infrastructure engineering ability first, and cloud provider second. Our delivery is on AWS, so deep AWS expertise is a strong advantage, but we're equally interested in exceptional engineers from Azure, GCP or multi-cloud backgrounds who understand the concepts and can pick up the specifics fast. • Deep understanding of platform and infrastructure engineering concepts, and the ability to explain why they matter, not just how they work. Experience with multi-account, multi-tenant or landing zone patterns, in any cloud, is a strong signal of this. • Strong hands-on Terraform and automation skills, with clear opinions on IaC structure and modularisation. We favour Terraform partly because it's cloud-agnostic, which fits how we think: the concepts travel, the provider is secondary. We care more about whether you can defend your reasoning than about any single answer. • Proven experience leading cross-functional teams and mentoring engineers. • Strong hands-on cloud knowledge, with the judgement to choose the right service for the job. Deep AWS expertise is highly beneficial. • Experience operating cloud platforms at scale, ideally in regulated environments. • Solid grasp of secure, scalable and resilient architecture, including how to prevent, detect and remediate security risks. • Awareness of SRE principles and operational priorities, experience with CI/CD pipelines, and strong system design skills. • Networking, data and identity depth all count strongly in your favour. • We hire people who are genuinely curious about technology. The engineers who thrive here tend to build and tinker beyond the day job, whether that's home automation, a side project, or pulling something apart just to understand it, and they can talk about it with real enthusiasm. That curiosity, paired with a growth mindset, matters to us as much as any single tool on your CV.
