Job description
Shopify Frontend Full Stack Engineer
Salary Range: $120,000.00 To $135,000.00 Annually
About Last Bottle Wines
Last Bottle Wines is a California-based direct-to-consumer wine retailer operating more than 2 dozen Shopify storefronts across multiple brands — Last Bottle Wines, Last Bubbles, First Bottle, and 2Tier Trading. We move fast, operate lean, and obsess over the intersection of great wine, smart logistics, and exceptional customer experience. Our technology team builds and owns the systems that make that possible.
The Role
We're looking for a seasoned Shopify frontend full-stack engineer who can own the storefront layer end-to-end — from Liquid/Hydrogen templates and custom Shopify Functions through backend integrations with our OMS (Linnworks), shipping platform (WeShip), and data infrastructure (Supabase / FastAPI / Prefect). You'll work directly with the Director of Technology Operations and be a key driver in our push to reduce agency dependency and bring more technical work in-house.
This is not an 'apply a theme and tweak CSS' role. You'll be architecting checkout extensions, building headless commerce features, writing macros, and shipping production code across a multi-brand storefront estate.
What You'll Own
Storefront & Theme Development
Own and evolve Liquid themes across all LBW Shopify Plus storefronts
Build and maintain Shopify Functions (discounts, shipping, payment customizations)
Develop Checkout Extensions using Shopify's UI Extensions framework
Implement and maintain metafield/metaobject schemas for product tagging across multiple brands
Coordinate multi-storefront deployments with zero cross-brand contamination
Headless & API-First Work
Build and maintain Python and React middleware layers interfacing with the Shopify Storefront API and Cart API
Design and implement Shopify webhook consumers in FastAPI / Python
Maintain and extend GraphQL integrations with Shopify Admin API
Contribute to headless subscription infrastructure (Stripe-based wine club)
Integrations & Backend
Extend Linnworks OMS integrations — macros, order sync, digital twin logic (Merge Order, SetOrderGeneralInfo patterns)
Contribute to the unified shipping integration platform (AfterShip, WeShip, Klaviyo event plumbing)
Write and maintain Python data pipelines for analytics and operational workflows
Participate in PostHog/Datadog/Supabase analytics instrumentation across storefronts
Technical Operations
Own vendor security reviews and forensic audits of third-party Shopify apps
Enforce and extend the multi-brand product tagging schema and Shopify Function conventions
Document architecture decisions and maintain internal runbooks
Support DTC compliance tooling (CCPA/CPRA flows, state-level checkout extensions)
Requirements
Must-Haves
4+ years of Shopify theme development (Liquid, Dawn or equivalent base theme)
Shopify Plus experience — multi-store, B2B, Checkout Extensibility
Python 3.x for backend services and scripting (FastAPI a strong plus)
REST and GraphQL API design and consumption
Experience with headless commerce architectures (Storefront API, Cart API)
Supabase or PostgreSQL for data modeling and querying
Git-based workflows, CI/CD, and production deployment discipline
Ability to read and write Shopify Admin API GraphQL mutations cold
Strong Pluses
Python orchestration for data pipelines
Klaviyo event and flow architecture for transactional/behavioral email
AfterShip or similar tracking/returns platform integrations
Stripe Subscriptions / Billing Portal integration
PostHog / Datadog analytics instrumentation and event schema design
DTC wine industry familiarity (compliance, carrier restrictions, age verification)
Monday.com automation or API usage
Who You Are
You ship. You don't wait for perfect specs — you prototype, validate, and iterate.
You own your work across the full stack. Bugs don't belong to someone else's lane.
You read vendor documentation and API changelogs before asking for help.
You have strong opinions about code quality but pragmatic judgment about tradeoffs.
You communicate clearly in writing and don't need daily standups to stay aligned.
Benefits: Medical, Dental, Vision, and 401K with company match
PTO: Paid Time Off (accrual starts upon employment) + 10 paid holidays
Remote-first with optional Napa/Bay Area in-person collaboration
