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
