Principal Software Engineer role at Koala Health, a pet health company with a pharmacy delivery service and new products in development. The role is hands-on technical leadership across the engineering org: architecture, engineering standards, and AI-assisted development practices. Requirements include expert Ruby on Rails and experience with AWS, GCP, or Azure.

At

Koala Health

,

we have our eyes set on an ambitious goal: to make managing your pet’s health simple and delightful. We’ve already launched our pharmacy service that allows people to shop for their pets’ medications and supplements online and get them delivered to their doorstep in presorted medication pouches. Now we’re focused on continuing to improve that experience while building a suite of new products and services that will make the pet health experience even better.

We are hiring a Principal Software Engineer to serve as a technical leader across the engineering organization.

This is a highly hands-on role for an experienced engineer who enjoys building production systems while also influencing architecture, engineering standards, developer productivity, and the adoption of AI throughout the software development lifecycle.

You will work closely with engineering, product, operations, and company leadership to identify opportunities, define technical direction, and drive execution on initiatives that have company-wide impact.

Success in this role means:


  • Architecting systems that scale with the business.
  • Raising engineering quality and operational excellence.
  • Accelerating development velocity through effective use of AI.
  • Establishing best practices for AI-assisted and agentic software development.
  • Mentoring engineers and helping the team make better technical decisions.
  • Leveraging technology to simplify complex operational workflows and improve customer experiences.
