Role Overview

Keep the current headless site stable and improving (next ~3–4 months)
Own day-to-day stability: triage issues, fix bugs, ship improvements, and keep releases moving
Improve performance and reliability across funnel pages (Collection → PDP → Cart → Checkout)
Support business-critical updates (launches, promos, pricing changes) without breaking conversion
Execute a mix of quick wins and targeted refactors to reduce fragility and regressions
Maintain analytics and tracking integrity so marketing, attribution, and testing don’t get corrupted
Operate with a clear constraint: we’re not looking for a big rewrite right now—we’re migrating, so we need pragmatic improvements that keep the business running
Provide technical input during the agency rebuild (collaborative, not meeting-heavy)
Instead, you’ll provide focused technical partnership to keep the rebuild accurate, maintainable, and launch-ready:
Provide technical guidance early (constraints, feasibility, integration requirements, edge cases)
Review key deliverables that benefit from engineering eyes (technical specs, implementation approach, critical PRs)
Join the working sessions where engineering input is genuinely needed (not every status meeting)
Answer agency questions quickly and clearly so they don’t guess—or build the wrong thing
Post-migration: Shopify theme execution + experimentation
Work within Shopify theme constraints intelligently (speed, maintainability, extensibility)
Build and iterate on features that support an ever-evolving ecommerce business
Enable experimentation: implement tests, iterate quickly, and ship improvements that move conversion and AOV
Maintain and extend apps/integrations cleanly (no duct-taping the stack)
Build lightweight documentation and internal runbooks so we can own what we ship
Frontend Development
Build and maintain React/Next.js experiences across the ecommerce funnel
Improve UX in ways that directly impact conversion, AOV, and subscription attach
Ensure performance and accessibility standards are met (Core Web Vitals matter)
Backend / Platform Development
Build and maintain APIs, serverless functions, and integration logic (TypeScript-heavy)
Debug issues across services: Shopify, internal tools, and third-party partners
Improve observability: logging, monitoring, error reporting, and alerting where needed
API Integration & Ecommerce Tooling
Integrate Shinesty systems with third-party tools (subscription, search, analytics, marketing partners)
Ensure reliable data flow and maintainable implementation patterns
Performance + Conversion Rate Optimization
Identify and resolve bottlenecks across frontend and backend systems
Implement smart, well-scoped A/B tests and iterate based on results
Partner with the Digital Product Manager to translate hypotheses into shippable changes**

Requirements

5+ years professional JavaScript experience (TypeScript strongly preferred)
3+ years React and/or Next.js experience
Strong experience building/consuming REST APIs (GraphQL a plus)
Ecommerce experience (Shopify strongly preferred)

Comfortable working in ambiguity and moving fast without perfect specs**
