Senior Infrastructure Engineer II

📋 Job Overview

For coaches, YouTubers, authors, podcasters, and other creatives, there isn't a better marketing hub to rely on to grow audiences, automate email marketing, and sell digital products — all within one platform.

🎯 The Role

We're looking for a Senior Infrastructure Engineer II to take ownership of a large share of Kit's core infrastructure: databases, Kubernetes, version upgrades, platform tooling, and day-to-day support. You'll also build the paved paths that let engineers, non-engineers, and AI agents test and ship changes safely.

The infrastructure supports creators who depend on Kit to reach their audiences and earn a living. When it's healthy, nobody notices. That's the job.

This is a full-time Individual Contributor role for an experienced infrastructure engineer who likes owning production systems end to end, takes on-call seriously, leans into automation and enjoys making other people's work easier.

✅ Key Responsibilities

• Own core infrastructure areas end to end: databases, Kubernetes, version upgrades, and platform tooling.
• Take your full share of on-call, which you'll start by the end of your first quarter.
• Become the go-to person for day-to-day infrastructure questions.
• Find one recurring source of pages and make it go away.
• Ship a first paved path, such as a sandbox environment where AI agents or non-engineers can safely build and test changes.
• Lead projects in Kit's core infrastructure without needing direction.
• Maintain uptime at 99.9% or better, reduce page volume, and find real cost savings.
• Build observability good enough for AI agents to handle some on-call load.
• Document your decisions so others can build on your work.

📌 Required Qualifications

• Running production infrastructure on AWS at scale, including managed relational databases, networking, and load balancing.
• Operating Kubernetes in production: upgrades, capacity planning, and troubleshooting.
• Managing infrastructure as code and maintaining CI/CD pipelines that engineers trust.
• Building monitoring and alerting that catches real problems early and doesn't page people for noise.
• Diagnosing complex, multi-service incidents calmly, then fixing the underlying cause.
• Cutting cloud costs through right-sizing and reserved capacity without hurting reliability.
• Writing clear runbooks, docs, and decision write-ups.
• Around 7 or more years in infrastructure, platform, DevOps, or SRE roles.
• Owning production infrastructure for a product where downtime costs customers money.
• Carrying a pager for systems you owned, and making that on-call rotation quieter over time.
• Leading a major upgrade or migration, such as a database or Kubernetes version upgrade, with little or no customer impact.
• Building self-service tooling or paved paths that other engineers actually adopted.
• Working on a small infrastructure team where you couldn't hand problems off to a specialist.

⭐ Desirable Experience

• Experience with Cloudflare, ephemeral or sandbox environments, or email sending infrastructure.
