Ecommerce Systems Engineer

Hiya is seeking an Ecommerce Systems Engineer to join our internal technology team. You will build and own internal projects across our Shopify storefront, subscription platform, middleware, and data infrastructure, and coordinate and collaborate with the external agencies we partner with on larger builds. Our systems include Shopify Plus, Order Groove, Cloudflare Workers, Git Hub Actions, Klaviyo, Snowflake, and the connectors behind Hiya's AI-amplified operating model.

We are looking for a collaborative team member who enjoys troubleshooting complex technical challenges, is excited by new technologies and gets the most out of AI tools, takes ownership of their work, and is self-directed: someone who sees what needs doing and acts on it without waiting to be told. You are comfortable with ambiguity, you write things down so the next person can pick them up, and you can explain a technical trade-off to marketing, finance, or a customer-service lead in plain language.

This is a mid-level, hands-on engineering role working directly alongside the VP of Technology. We are looking for someone who has shipped and owned production commerce systems, is comfortable in this architecture on day one, can troubleshoot whatever the business throws at technology, and uses AI coding tools as a daily practice rather than a novelty. AI is a multiplier here, not a substitute: you have years of writing code by hand, you read and reason about code you did not write, and you can debug Liquid, JavaScript, or a failing pipeline with the tools turned off.

You will also bring engineering discipline and oversight, and raise the bar for the team.

• Own the Shopify Plus codebase:
  Liquid, theme architecture, Shopify Functions, Checkout Extensibility, and the Admin GraphQL API.
• Own the storefront deployment pipeline (Git Hub Actions, blue/green theme deploys, settings sync) and its secrets, tokens, and access.
• Act as the pull-request review gate for agency and contractor work; hold the bar on quality, security, and change control.
• Build storefront features and fixes directly when it is faster to do in-house; scope and hand off larger builds to agency partners with clear requirements and acceptance criteria.

• Build and maintain Cloudflare Workers and serverless services connecting Shopify to Order Groove (subscriptions), Klaviyo, Flowspace (WMS), and our data warehouse.
• Design and debug API integrations (REST and GraphQL), webhooks, and event flows across the stack.
• Write the scripts, Shopify Flows, and small internal tools that automate operational work (bulk operations, data fixes, guardrails against bad orders) so routine needs do not wait on an agency queue.
• Instrument and monitor integrations so failures surface before customers or finance notice.

• Build and operate the connectors (MCP servers on Cloudflare), data pipelines into Snowflake, and dashboards that give every department AI access to its own data.
• Design permission models so shared context is inherited safely per user and department.
• Use AI coding assistants daily and help the wider team adopt them well.

• Be the technical first responder for production issues across storefront, subscriptions, fulfillment, and integrations.
• Run root-cause investigations using the Admin API, logs, and vendor APIs; document findings and recommend the fix before making it.
• Turn incidents…
