Principal Engineer

Join Wagmo, a fast-growing pet wellness and insurance company. As a Principal Engineer, you will own the application architecture, set technical direction, and mentor tech leads. Enjoy equity, unlimited paid time off, and a supportive work environment.

• As Principal Engineer at Wagmo, you will be responsible for owning the application architecture, setting technical direction across various domains, and leading the architecture review process. You will also be involved in mentoring squad tech leads and raising the standard of technical design across the team.

• Comfort that "principal" here means unblocking two squads rather than presiding over ten. Experience in insurance, benefits, payments, healthcare, or another regulated, integration-heavy domain is a strong plus
• Experience holding a cross-cutting architectural decision that touched several domains at once, and driving it from ambiguity to a shipped, documented outcome that other engineers built on. You should be able to name the option you rejected and the cost you knowingly accepted
• The judgment to say what not to build, and the written and verbal clarity to carry that argument with people who outrank you
• A track record of retiring and scaling systems, not just building them. You have lived inside a half-migrated codebase running two paths in parallel and know what it takes, organizationally as well as technically, to finish
• Experience putting non-deterministic systems into production, with real opinions about evaluation, versioning, and who is allowed to change a model's behavior
• Depth in Python and Django, relational data modeling, and third-party integration at scale. Familiarity with Kubernetes and GCP is useful; you will not own the cluster
