We are building a platform that makes it easier for patients to find the right providers, access the right medications, and take control of their health with transparency and trust. We're looking for a Staff Software Engineer, Growth to help accelerate our product's impact by building and optimizing the systems that drive acquisition, activation, retention, and monetization.
Requirements
- 5+ years building production web software with clear business impact.
- Full-stack fluency: Strong back-end and infra skills (APIs, auth, cookies, HTTP/CDN) with enough front-end to extend Framer and build/track landing pages.
- Instrumentation end-to-end: Event design, tag management, server-side forwarding, experiment wiring.
- SEO fundamentals: Core Web Vitals, crawlability/indexing basics, structured data/sitemaps.
- Fluent in SQL and Python.
- Working familiarity with GTM, ad pixels, and Google Analytics (for integration/QA).
- Mobile growth basics: Deep linking, install attribution concepts, and experience wiring webapp journeys.
Responsibilities
- Design, build, and ship features across the stack (frontend, backend, and data pipelines) to improve conversion, engagement, and retention.
- Maintain and improve server-side event forwarding, and a clean event schema across marketing site and app.
- Identity & attribution enablement - Make identity resilient across domains; enforce UTM governance; ensure data needed for rules-based attribution is consistently available.
- Work with design to build and iterate high-performance landing pages and lightweight micro-tools that capture intent and convert.
- Partner with product, design, and data to identify high-impact opportunities and rapidly test hypotheses through experiments and A/B testing.
- Own the engineering work that drives acquisition and lowers CAC: reliable measurement (client + server), durable identity across web/app, fast landing experiences and micro-tools, and the plumbing that enables rapid experiments and trustworthy attribution.
Other
- Full-time / Onsite (5 days/week)
- This role is ideal for someone who thrives in fast-moving environments, enjoys wearing multiple hats (frontend, backend, and data), and loves using creativity and rigor to solve ambiguous growth challenges.
- Strong Product sense: Can turn ambiguous growth ideas into minimal, testable releases and ship quickly without trading correctness.
- Experimentation rigor: Knows how to design trustworthy A/B tests (power, guardrails, sequential testing pitfalls).
- Attribution literacy: Has shipped or worked closely with multi-touch attribution or MMM, and understands trade-offs of each.
