Lead DevOps Engineer

DevOps at Stellar Health is in charge of supporting an increasingly diverse infrastructure setup, and support systems built by an increasing number of engineers.

The original system was rather simplistic - a Django Application on top of Postgres, with a cron-driven ETL ingestion pipeline. While we have evolved this incrementally since to support customer growth (added Redis for caching, Celery for tasks, Elastic Search to serve certain jobs, a Postgres read replica to scale out some of the growth), due to increased customer growth we are now at the cusp of building the next generation of systems and infrastructure.

As a Lead DevOps Engineer, you will partner with the Director of DevOps to guide the engineering team through this infrastructure evolution, and be responsible for its scalability, monitoring, and general good performance and reliability.

As we transition to more complex usage of servers, we expect your team to be able to not only be a stakeholder in informing teams’ systems design, but also a partner to the engineering team when it comes to release management, CI/CD setups, build cop and on-call rotations.

Originally, our systems diagram looked like this:

Over the next year our systems will change significantly - and the DevOps team will be in charge of helping us transition safely and smoothly to our next generation infrastructure.

Systems / infrastructure setup and deployment

• Manage application deployment infrastructure across Aptible and AWS. Our ETL’ing infrastructure, queueing, and application serving infrastructure are growing. Your responsibility is to ensure that it is set up in a HIPAA compliant, scalable, and resilient way.
• Migrate, set up and own new cloud deployments on AWS in a HIPAA compliant way. Ensure that engineering is set up to deploy new services on AWS in a safe manner.
• Deploy and set up internal services (Redis, Elastic Search, Postgres) to match engineering business needs. Work together with engineering to coordinate upgrades of these systems to newer versions, scale, etc. Be responsible for the uptime of these services.
• Evolve our logging, monitoring, and alerting - and drive a best in class engineering On Call rotation that allows us to ensure high availability of our production systems.

Developer productivity tools

• Evolve our release process to make it easy for engineering to deploy and roll back releases. Help the engineering team move to a daily release cycle through speedy and automated deployments and rollbacks.
• Support the engineering organization through setting up our testing infrastructure in a way that allows for faster deployments.
• Build tooling to eliminate toil, streamline standards, and automate processes

• 5+ years of experience in a hands-on DevOps, Site Reliability (SRE), or Platform Engineering role.
• Work experience managing compliant infrastructure is a must.
• Working with Aptible, or modern AWS/GCP setups is a plus. We are a startup and the kinds of infrastructure startups have is significantly different from big companies.
• Experience with Terraform, Ansible, or other configuration management tools.
• Experience with a modern programming language (Python, JS, Go, etc).
• Experience with observability tools such as Datadog, NewRelic, Prometheus, Grafana, or similar.
• Familiarity with one or more CI/CD platforms (CircleCI, GitHub Actions, Jenkins, etc).
