Senior Software Engineer, Core Infrastructure

About the role

Imgix is a chief platform for real-time visual media management, optimization, and delivery services. We empower businesses to deliver high-quality visual experiences to their customers across platforms and devices, anywhere in the world. We process billions of image and video requests per day, and behind that is production software — and we need someone who’s great at writing it.

Responsibilities

• Write and maintain production Python services that handle billions of daily requests, including our core rendering and delivery infrastructure.
• Design systems with failure modes, cost, and performance in mind — then own them through deployment and beyond.
• Create infrastructure tooling and automation (Terraform, CI/CD, Docker) that makes the whole team faster.
• Collaborate across engineering on cloud cost optimization, balancing reliability and performance with real budget constraints.
• Contribute to maintaining 99.99%+ uptime through monitoring, incident response, and on-call rotation.
• Create clear documentation - operational references, design docs, alert guides - so the systems you build are understandable by the whole team.

Requirements

• Strong Python developer. You write clean, maintainable production code — not scripts on the side of an ops role.
• Cloud infrastructure experience. 5+ years working with a major cloud provider (Google Cloud Platform strongly preferred; Amazon Web Services/Azure also considered), including multi-region deployments.
• Infrastructure-as-code fluency. Terraform or OpenTofu experience. You define infrastructure in code and deploy it through CI/CD.
• Linux fundamentals. Comfortable in the operating system your services run on.
• Operational ownership mindset. You've been on-call, you've triaged production incidents by reading logs and metrics rather than following a script, and you've dug into root cause on your own.
• Clear communicator. We're a fully remote team. Strong async written communication matters as much as technical skill.

Qualifications

• Bachelor's degree in Computer Science or related field.
• Experience with CDNs, caching infrastructure, or visual media pipelines is a plus.
• Familiarity with compliance frameworks such as GDPR and SOC 2 is a plus.

Skills

• Python programming
• Cloud infrastructure (GCP preferred)
• Terraform or OpenTofu
• Linux command line
• Operational ownership mindset
• Strong communication skills

Benefits

• Medical, dental, vision insurance
• 401(k) plan
• Paid time off
