Kit is the email marketing platform experts choose to grow their audience, deepen their relationships, and build a business around the work they love. 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.

More importantly, there isn’t a team more committed to helping creators earn a living. We’re on a mission to help creators earn $1 billion using our creator marketing platform. We have always been 100% independent and 100% remote.

We are proud to have built a product that our customers love, and we look for people who have enthusiasm and belief in our mission, vision, and values to join our team. We’re also embracing AI thoughtfully — both in how we build and how we hire to ensure our team is adaptable, innovative, and ready for what’s next.

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.

YOUR SUPPORT SYSTEM

You’ll report to Mojtaba Hosseini VP of Engineering at Kit. Day to day,



you’ll work most closely with Kris Hamoud and Ivan Mora Perez

You’ll also partner with product engineers across Kit, and with teams outside engineering who rely on infrastructure to get their work done. Once you’re ramped up, you’ll join a three-person on-call rotation, which works out to roughly one week in three.

WHAT YOU’LL DO

– First Week: Get access to our AWS accounts, Kubernetes clusters, monitoring, and CI/CD pipelines. Read through our runbooks and architecture docs. Take part in Get To Know Yous (GTKYs) with Kris, Ivan, and the engineering teams you’ll support.

– First Month: Pick up day-to-day infrastructure support requests and start working through them with Kris and Ivan as backup. Ship your first improvement, such as a version upgrade or a fix to a gap in monitoring. Shadow on-call shifts. Write down what you learn along the way, especially the parts that only lived in someone’s head or those that can be automated or improved.

– First Six Months: 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.

– First Year: You’re the primary owner of a large part of Kit’s core infrastructure, and you lead projects in it without needing direction. Uptime stays at 99.9% or better, page volume is down, and you’ve found real cost savings. Your paved paths are in regular use by engineers, non-engineers, and AI agents. You’ve built observability good enough for AI agents to handle some on-call load. You’ve documented your decisions so others can build on your work.

WHAT WILL S.E.T. YOU UP FOR SUCCESS

Skills

– 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

– Nice to have: experience with Cloudflare, ephemeral or sandbox environments, or email sending infrastructure

Experiences

– 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 upgra
