What you'll do

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
