Senior Infrastructure Engineer

The Adventure Begins. 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. With projects as dynamic as migrating our entire fleet to ECS and re-architecting our Terraform universe, your role is pivotal. This isn't just a job; it's an epic tale of transformation and triumph.

As a 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, Opensearch, and ECS to build and manage robust cloud environments.
• Terraform: Leverage Terraform for infrastructure as code to efficiently manage and provision our cloud resources.
• Nix/NixOS: Use Nix to create reproducible and declarative configurations across our systems.
• Monitoring and Observability Tools: Employ Prometheus, Grafana, Opensearch, 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:

• Take charge of our cloud architecture by migrating services to Docker, separating production and staging environments, and enhancing system resilience.
• Advance our monitoring and alerting frameworks to minimize direct system access and improve operational efficiency.
• 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 3+ years of experience managing large-scale Terraform implementations, including the setup and maintenance of Terraform CI/CD pipelines.
• You have 3+ years of experience using configuration management tools such as Nix/Ansible, maintaining consistent and automated system configurations across multiple environments.
• 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 extensive experience, ideally 3 years or more, with observability and monitoring tools like Prometheus, Grafana, and OpenTelemetry, optimizing system performance and reliability.
