We are looking for a Shopify Developer to join Lake House Group and help us deliver better, faster, cleaner ecommerce work across our client portfolio.

This role exists because our Shopify development workload is growing, and because the way we build is changing. AI coding agents are now part of the workflow. They do not replace judgment, QA, architecture, or taste. They do change what a strong developer can ship when they know how to use them properly.

We need someone who is already strong in Shopify and wants to get much stronger in an environment where development, product ownership, Klaviyo, CRO, AI operations, and client strategy are connected.

If you want to build inside real ecommerce systems, solve messy Shopify problems, collaborate with people who understand the business side, and help define how an AI-powered agency ships development work, keep reading.

The Role

The Shopify Developer will work across Lake House Group's Shopify client portfolio, shipping theme work, custom sections, bug fixes, storefront improvements, integrations, technical cleanup, and operational improvements that help brands run better.

You will work closely with Product Owners, designers, CRO, email and retention specialists, and our AI/operator team. Some work will come as clear implementation tasks. Some work will require you to ask better questions before building. The best developers here are not just code executors. They understand why the work matters and can flag when the requested solution is not the right one.

You will be expected to use AI coding tools as part of your day-to-day workflow. That means accelerating implementation, exploring options, reviewing generated code critically, and building your own habits around QA, prompts, reusable snippets, and development workflows. We are not interested in someone who blindly accepts AI output. We are interested in someone who can use AI to go further while still owning the quality of what ships.

A typical week could include building a custom Shopify section for a product page, fixing a layout bug across mobile breakpoints, wiring metafields or metaobjects into a theme, helping QA a CRO test variant, cleaning up a theme performance issue, reviewing an AI-generated implementation before it goes to preview, supporting a Shopify POS or app integration question, and writing a short technical note so the Product Owner can explain the change clearly to the client.

The work is varied. You will move across multiple brands, verticals, and storefront setups. Context switching is real. So is ownership.

Reality Check

Lake House has tripled in size over 3 years and is aiming to do it again. We are a small team building at the edge of Shopify, Klaviyo, AI operations, and ecommerce strategy.

This is not a large engineering department with a narrow lane for every person. You will have support, but you will also need to think, communicate, and make good calls. We care about quality, but we also care about pace. We do not want sloppy work shipped faster. We want better systems, better tooling, and better judgment so the team can move faster without creating debt.

We are also actively changing how development work happens. AI coding agents are part of that. Some workflows are already useful. Some are still being shaped. You may be the person who finds a better way to QA a generated theme change, structure a reusable prompt, or turn a recurring bug pattern into a more reliable internal process.

If you want a polished development machine where everything is already figured out, Lake House may feel too fluid. If you want to help build the machine while doing real client work, it will feel exciting.

Non-Negotiables

• 3+ years building on Shopify. You have real experience with Shopify themes, Liquid, sections, templates, metafields, app embeds, Shopify admin, and the practical weirdness of ecommerce storefronts.
• Strong front-end fundamentals. HTML, CSS, JavaScript, responsive behavior, accessibility basics, browser debugging, and performance tradeoffs are comfortable territory.
• Liquid and Shopify theme confidence. You can read an existing theme, understand how data moves through it, make clean changes, and avoid breaking client-editable behavior.
• Git and development workflow discipline. You can work on branches, review diffs, write clear commits, handle feedback, and avoid careless production risk.
• QA mindset. You test your own work before handing it off. Mobile, desktop, edge cases, links, forms, variants, metafields, and weird product data all matter.
• AI fluency. You already use tools like Claude Code, Cursor, ChatGPT, or similar to write, debug, refactor, research, and QA. You understand that AI is leverage, not a substitute for technical judgment.
• Ecommerce curiosity. You care about how stores actually sell. Conversion, merchandising, product data, checkout expectations, retention, and operations are not someone else's problem.
• Clear written communication. You can explain what changed, what is risky, what needs QA, and what a Product Owner or client should know.
• Ownership mentality. If a ticket is unclear, you ask the right questions. If something looks wrong, you flag it. If you break something, you say it quickly and fix it.

Nice to Have

• Experience with multi-language, multi-market, or multi-currency Shopify setups.
• Experience in an agency environment with multiple clients in parallel.
• French is a strong plus, especially for Quebec client context, but not required if your written communication is excellent.

What Makes Someone Succeed Here

You are practical and curious. You like shipping, but you do not confuse motion with progress. You can take a messy ecommerce request and turn it into a clean implementation path. You are comfortable saying, "I can build that, but here is the risk," or "There is a simpler way to get the outcome."

You use AI seriously, but you do not outsource your brain to it. You review the output. You test it. You improve the workflow. You care about building reusable leverage for yourself and the team.

You are not precious about the work. Some days are custom sections and architecture decisions. Some days are bug fixes, theme cleanup, QA, and small changes that matter to the client. You treat both with care.

What We Offer

• Competitive salary, discussed during the interview process.
• Remote or Hybrid work, with our downtown Montreal WeWork office as the team anchor.
• Wellness allocation.
• Unlimited access to AI tools. We invest in the infrastructure so you can push your workflow.
• A small team where strong people have real impact.
• Exposure to Shopify, Klaviyo, CRO, AI operations, and ecommerce strategy in one environment.
• Autonomy, trust, and a high quality bar.
• A learning environment. We are obsessed with getting better.

How To Apply

Apply with:

• Your LinkedIn profile or resume.
• Two or three Shopify projects you worked on, with a short note on what you personally owned.
• A short example of how you currently use AI in your development workflow.
