About this role
Senior Cloud Infrastructure Engineer
Signal 1 is building the AI management and orchestration layer for the next era of healthcare AI. Health systems are rapidly moving from predictive models and generative AI to autonomous agents that can take action across clinical, operational and administrative workflows. This shift creates an entirely new set of challenges around how AI is governed, monitored, managed, and orchestrated to deliver real enterprise value.
Signal 1 is the partner of choice for the most ambitious and AI-forward health systems. Our AI Management System (AIMS) enables them to manage their entire AI portfolio today while providing the infrastructure they need to confidently adopt agentic AI and whatever comes next. Our customers include leading health systems such as NewYork Presbyterian, Inova, and Mount Sinai.
We’re a small, ambitious team tackling problems that don’t yet have an established playbook. Joining Signal 1 means helping shape not only our products, but how health systems manage and put the next era of AI to work.
We are looking for a Senior Cloud Infrastructure Engineer to join our small, hands-on Infrastructure Team. You will:
- Design, build, and run the Azure infrastructure behind Signal 1's products using infrastructure as code.
- Build deployment pipelines that take code from commit to production across multiple environments.
- Help shape the architecture of the whole system, from the application to the infrastructure and everything in between.
- Troubleshoot live issues together with our software engineers.
- Build full-stack internal tools that automate the Infrastructure Team's everyday work.
- Keep the platform secure, compliant, and reliable, including monitoring, backups, and recovery.
- Own components and projects from idea to production, and bring new ideas that make the whole team faster.
Required Qualifications:
- 5+ years of experience in cloud infrastructure, DevOps, or platform engineering.
- Strong hands-on experience with at least one major cloud platform (Azure, AWS, or GCP).
- Production experience with Kubernetes, Helm, Terraform, and continuous integration and delivery tools such as GitHub Actions.
- Strong networking knowledge, including designing and building secure cloud networks.
- Python and Bash scripting skills, and the ability to read and understand application code.
- A clear understanding of how every part of a modern software system works together, end to end.
- Strong communication skills, with the ability to pick up context fast, bring useful ideas to technical discussions, and explain complex topics in plain words.
Preferred Qualifications:
- Experience with Azure, Terragrunt, Istio, and Datadog.
- Experience designing multi-tenant SaaS environments where each customer's data is isolated.
- Experience building full-stack internal tools, such as deployment or operations tools.
- Familiarity with HIPAA and SOC 2, and experience handling protected health information (PHI).
- Experience deploying software into customer-managed or private network environments.
- Experience in small startup teams that build and ship fast.
