Senior Full-Stack Engineer – E-commerce (Shopify)

What You’ll Do

• Design and build interactive, performant web frontends using modern JavaScript frameworks (React, Next.js, Shopify Hydrogen/Remix, etc.)
• Develop and maintain scalable, cost-efficient backend services and APIs (Node.js, Python, etc.) on AWS (Lambda, S3, EventBridge, SQS, etc.)
• Build and extend our Shopify platform: custom apps, Shopify Functions (discounts and more), checkout customizations, and Admin/Storefront API integrations
• Own pricing and inventory logic in Shopify across Markets and Catalogs - price vs. compare-at price, multi-currency, multi-region availability, and inventory levels
• Integrate with third-party APIs and platforms (e.g., Stripe, ERP, PIM, search and recommendation engines)
• Work with open-source libraries to create experimental and production-ready features
• Prototype and test AI-driven features
• Own features end-to-end - from technical design and architecture through testing, deployment, and monitoring
• Contribute to and improve our CI/CD deployment pipelines
• Write and maintain the right mix of unit, functional, and end-to-end tests
• Understand our business and engineering processes, and look for ways to improve and automate them
• Make every deliverable a step toward the team’s longer-term technical vision, rather than a one-off solution
• Mentor junior developers through pairing, code reviews, and knowledge sharing - taking the time to explain what you know rather than trying to do everything yourself
• Stay hands-on and experimental - we’re a team that loves trying new ideas fast

What We’re Looking For

• 5+ years of experience in software development, ideally across both frontend and backend
• Strong, hands-on experience with Shopify (Admin and Storefront GraphQL APIs, metafields, webhooks, checkout)
• Good understanding of Shopify Functions, particularly for discounts
• Good understanding of pricing and inventory in Shopify - Markets and Catalogs, price and compare-at price, inventory locations and levels
• Strong command of JavaScript/TypeScript and modern frameworks (React, Next.js, Vue)
• Proven backend experience with Node.js, Python, or similar - and solid API architecture skills (REST/GraphQL)
• Good understanding of AWS services (Lambda, S3, EventBridge, SQS, etc.) and event-driven architectures
• Good understanding of a typical deployment pipeline (CI/CD, environments, release and rollback)
• Good understanding of different testing approaches - unit, functional, and end-to-end testing
• A habit of building solutions that are cost-efficient and designed to scale
• Big-picture thinking - you connect each step you take to where the team is trying to get to
• Strong communication skills - able to clearly describe a feature, and walk through an entire tech stack architecture, for both technical and non-technical audiences
• Highly motivated and proactive - you spot problems and opportunities and take initiative without waiting to be asked
• A collaborative mindset - you enjoy working alongside other developers and mentoring junior team members
• Experience integrating AI tools (e.g., OpenAI, Google, Meta) into user-facing products
• Passion for clean, scalable code and rapid prototyping

Bonus Points

• Experience with Shopify Hydrogen and Oxygen
• Experience building custom Shopify apps
• Experience with bundle products and customized/configurable products in Shopify
• Experience using Shopify to sell to businesses (B2B) and with Shopify POS
• Experience with WebAR, 3D (Three.js, A-Frame)
• Familiarity with vector databases or AI embeddings for semantic search
• Contributions to open-source projects or technical writing
• Interest in generative AI, LLMs, or real-time computer vision
