Job description

What We Do Wagmo is a modern pet healthcare company built around how pet parents actually care for their pets. We partner with employers to provide a complete approach to pet and pet-parent wellbeing, from preventive wellness plans and emergency coverage to 24/7 pet telehealth guidance. Our purpose is to unlock every pet parent's potential to provide extraordinary care, and we do it by bringing the same intentionality to pet benefits that the best employers bring to human healthcare. Founded in 2017 and female-founded, Wagmo is headquartered in New York City and trusted by leading employers nationwide. What’s Important To Us Our mission shapes everything we build and how we work together. We take fearless ownership of outcomes, collaborate with radical candor, and are always driven by the customers and pet parents who trust us. We think critically, follow through relentlessly, and find the extra 10% that turns good work into exceptional work. We keep it weird because the obvious answer is rarely the most interesting one. Our values aren't aspirational. We interview for them and hold each other accountable to them. If what you've read so far resonates with you and you want to be part of a team where every person makes the company meaningfully better, we'd love to hear from you.. About The Role As Principal Engineer at Wagmo, you will be the named owner of our application architecture. Wagmo sells pet wellness and insurance directly to consumers and through employers, brokers, and benefits administrators. Over the past two years we moved our insurance program to a new carrier partner and built a provider-agnostic interface to make that possible. It works, and it is not finished: two generations of models still coexist behind feature flags, and the legacy path has to be supported for years. On the partner side, each new benefits administrator we onboard currently arrives as its own build, with its own file format, renewal cadence, and eligibility rules. Our growth depends on that stopping. Architecture has been owned by the CTO to date. This role takes it over. You will set technical direction across insurance, claims, partner integration, and our AI systems, decide what we will not build, and leave designs that two squads can execute without escalating. You will do this with no direct reports, real influence, and your hands in the codebase. The scope here is wide for our team, which is the appeal and also the challenge. There is no platform organization beneath you and no architecture review process to inherit beyond the one we started this year. Our Tech Stack: React · Python · TypeScript · React Native · Kubernetes · Django · Next.js · Node.js · Flutter (legacy) · builder.io builder.io · GitHub · Slack · Notion · Claude Core Responsibilities - Own the end state of Wagmo's insurance provider interface, including a documented retirement path for legacy provider models and the decision about when dual-write paths come out. - Design partner and carrier onboarding so that adding a new benefits administrator is a configuration exercise rather than an application build. File format, renewal cadence, group structure, and product eligibility should be configured, not coded. - Own architecture review: run it, hold decision rights in it, and maintain a decision log that the team can rely on. Success is squads unblocked without escalation. - Define a single identity architecture spanning enterprise SSO tenants, our partner portal, and consumer authentication, with per-tenant onboarding reduced to a documented, repeatable process that stands up to enterprise security diligence. - Own the architecture of our AI systems across claims adjudication, customer support, and internal engineering tooling: versioned prompts and strategies with a promotion path, controls that match their documentation, and a measured cost per automated decision. - Mentor squad tech leads and raise the standard of technical design across the team, without taking on people management. What You’ll Need To Be Successful - 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. - 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. - 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. - Experience putting non-deterministic systems into production, with real opinions about evaluation, versioning, and who is allowed to change a model's behavior. - The judgment to say what not to build, and the written and verbal clarity to carry that argument with people who outrank you. - 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. Why Consider This Role? - Pet spending in the U.S. has reached $200 billion and the category is still early in its lifecycle. Wagmo is building the platform to lead it. This role is the architecture of that platform, at the moment the decisions are still open. - Wagmo is a female-founded, Inc. 5000 recognized company where performance matters more than pedigree. We are growing fast, building something that matters, and there is real ownership equity in that journey. - The team is exceptionally smart, curious, and kind, led by transparent and low-ego leadership. We take the work seriously and never take ourselves too seriously. This is not a traditional 9-to-5 job. It asks for real dedication and impact, and gives you genuine flexibility and autonomy in return. Key Benefits - Comprehensive health, vision, and dental coverage - HSA/FSA - 401(k) retirement planning with employer matching - Unlimited paid time off - Annual company holidays - Additional company-wide recharge days off - 12 weeks parental leave for eligible employees - Company paid Wagmo pet wellness and insurance plans - Regular company-wide events and team gatherings - Pet-friendly office - Catered lunches
