Software Engineer - Infrastructure

About the role

The Infrastructure team at Mercury is an enablement lever for the rest of the business, building scalable, secure, and maintainable foundations for the organization. We focus on creating platform features that make it easier for agents and humans to deploy code—secure by default, observable by default, and easy to use—while maintaining speed and shipping to production daily.

We maintain everything from networking to container orchestration and collaborate with product teams to enable their AWS needs. This role is ideal for someone passionate about building maintainable systems, obsessed with quality, and eager to solve problems alongside product counterparts. You’ll go deep, ship often, and leave systems better than you found them—prioritizing quality without bureaucracy.

Responsibilities

• Build Mercury’s “Infrastructure Platform” to support the growing needs of the engineering organization, ensuring it is AI-friendly while remaining usable for human engineers.
• Deliver key infrastructure projects, break down complex initiatives, and define infrastructure strategy through detailed RFCs and technical specifications.
• Collaborate with product teams to enable AWS needs and improve platform usability.
• Debug low-level Linux issues and help product engineers understand production behavior.
• Contribute to agentic infrastructure: systems that allow AI agents to safely interact with infrastructure while providing guardrails for both agents and human operators.

Requirements

• 2+ years of experience with AWS.
• Strong knowledge of low-level operating system foundations (Linux, file systems, containers, etc.).
• Keen interest in cloud-native open-source technologies and comfort contributing code upstream.
• Demonstrated ability in technical writing, with 2+ years of experience creating detailed technical documentation, RFCs, and tech specs.

Preferred Qualifications

• Experience operating in regulated environments (e.g., HITRUST, SOC2).
• 2+ years of experience working in large Terraform environments with many contributors.
• 2+ years of experience writing code to support infrastructure platform development.
• Willingness to learn and dive into hard problems.

Technology Stack

Our infrastructure is built primarily on AWS (EC2, RDS, OpenSearch, ECS, EKS) using cloud-native open-source tooling. We manage infrastructure as code with Terraform, use GitHub and GitHub Actions for version control and delivery, and rely on Prometheus, Grafana, OpenSearch, and OpenTelemetry for observability.
