AI in this role

Imagine being a pioneer, venturing through the uncharted territories of the cloud. You're not just navigating; you're shaping the landscape, constructing robust architectures that withstand the tests of time and scale. At Mercury, your mission, should you choose to accept it, is to help steer our cloud infrastructure into the future. We are building ephemeral environments in Kubernetes, building the foundations for non-technical folks to ship changes via an agent coding platform and building safe and secure networks for other platform teams to build inside.

As a senior member of our infrastructure team, you will be equipped with essential tools and technologies designed for scaling and enhancing Mercury's infrastructure:

AWS Services: Proficiently utilize EC2, RDS, IAM, Networking, ECS and EKS to build and manage robust cloud environments.
Terraform: Leverage Terraform for infrastructure as code to efficiently manage and provision our cloud resources.
Agentic Infrastructure: Build the frameworks around using AI safely in our infrastructure, both for the agents and the users that kick off those agents.
Monitoring and Observability Tools: Employ Prometheus, Grafana, and OpenTelemetry to maintain high availability and monitor system health.
Version Control and CI/CD: Manage code and automate deployments using GitHub & GitHub Actions.

As we gear up for the next stages of Mercury's growth, you will:

Build our “Infrastructure Platform” to support the growing needs of the Engineering Organization.
Focus on building a platform that is AI friendly while still usable for engineers. We want our users to be humans and Agents.
Lead key infrastructure projects, break-down complex initiatives, and define our infrastructure strategy through detailed RFCs and technical specifications.

Must haves:

You have 5+ years of experience with AWS.
You have extensive experience, ideally 3 years or more, with observability and monitoring tools like Prometheus, Grafana, and OpenTelemetry, optimizing system performance and reliability.
You are interested in scaling and building a fledgling EKS infrastructure platform from the ground up.
You have demonstrated ability in technical writing, with at least 3 years of experience creating detailed technical documentation, RFCs, and tech specs that clearly communicate complex ideas.

The ideal candidate should:

You bring at least 2 years of experience leading infrastructure projects in regulated environments such as HITRUST or SOC2, ensuring compliance and security.
You have 3+ years of experience managing large-scale Terraform implementations, including the setup and maintenance of Terraform CI/CD pipelines.
You have 2+ years of experience writing code. We are building an Infrastructure Platform from scratch and there is plenty of code to write to support that.
Experience mentoring and elevating those around you, we are force multipliers for the engineering org.
