Scale is hiring an Infrastructure Software Engineer for the Apps Platform Infrastructure team in London. You'll build and evolve the platform's deployment and observability layers across multiple cloud providers and on-premises environments, serving both internal teams and customer-managed deployments.
In this role, you'll expand the deployment footprint to cover on-premise, all major cloud platforms, and beyond. You'll ensure fast, secure, and reproducible deployments across all supported cloud service providers and on-premises infrastructure. A key focus is expanding platform observability so that forward-deployed infrastructure teams can efficiently operate customer deployments.
You'll partner closely with internal teams to understand their deployment needs, debug issues, and build tooling that serves their use cases. You'll respond to incidents and production issues with urgency, conducting root cause analysis and implementing preventive fixes. You'll help develop and maintain a product roadmap for deployment and observability, lead architecture reviews, and own projects end-to-end from design through deployment in fast-paced cross-functional settings.
Scale develops reliable AI systems for critical decisions, providing high-quality data and full-stack technologies that power leading models. The company works with industry leaders like Meta, Ernst & Young, Mayo Clinic, and U.S. government agencies including the Army and Air Force.
REQUIREMENTS:
- 5+ years of experience building and deploying enterprise and public sector solutions across AWS, Azure, GCP, OCI, and on-premises

- Deep proficiency with IaC, containerization, and orchestration tools (Kubernetes, Terraform, Docker)
- Comprehensive understanding of CI/CD pipelines and software delivery principles using GitHub Actions or CircleCI
- Experience with GitOps-style deployments and a track record of ensuring consistent, repeatable deployments
- Strong debugging skills and ability to navigate performance/security tradeoffs in production systems
- Comfort with ambiguity and ability to context-switch between reactive incident work and proactive product development
NICE TO HAVES:
- Experience as a founder or early engineer at an infrastructure-focused startup, owning a product end-to-end
- Experience running secure workloads in multi-tenant or untrusted environments (e.g., FaaS, CI sandboxes, remote notebooks)
- Open-source contributions to systems or developer-tools projects
- History of on-call/incident response for production systems
