- Write, review, and debug transform scripts that modify storefront responses at the edge, ensuring correctness across device types, locales, and customer groups
- Actively monitor customer trials and react to issues or anomalies fast, whether that’s a code change, or an internal escalation — speed of solution is key
- Use browser DevTools, Honeycomb, and Nostra's internal APIs to diagnose caching anomalies, TTFB regressions, and personalization conflicts in production environments
- Own the technical relationship with a portfolio of merchant accounts — acting as the primary engineering point of contact for escalations
- Build internal tooling, documentation, and playbooks that scale the team's ability to onboard and support customers faster
- Surface product feedback from the field — you'll have more first-hand exposure to real-world edge cases than anyone else in the company, and your input will directly shape the roadmap
What we're looking for
- 2–5 years of experience in a technical customer-facing, or engineering role (solutions engineering, forward deployed engineering, full stack engineer, or similar)
- Proficiency in JavaScript — you're comfortable reading, writing, and debugging JS in a browser context without hand-holding
- Solid understanding of how the web works: HTTP, caching headers, CDNs, DNS, and browser rendering
- Experience with Shopify storefronts (Liquid, Hydrogen, or headless) is a strong plus; familiarity with SFCC or other enterprise platforms is a bonus
- Comfort working in production environments under pressure — you know how to isolate a problem, form a hypothesis, and verify it without breaking things
- Strong written and verbal communication — you can explain a cache invalidation strategy to a merchant's VP of Engineering and their Head of eCommerce in the same conversation
- Experience with Cloudflare Workers, CDN configuration, or edge compute platforms
- Familiarity with A/B testing frameworks and experimentation tooling
- Background in ecommerce performance optimization (Core Web Vitals, LCP, TTFB)
- Experience working across GitHub repos in a collaborative eng environment
