About the role

Grüns is hiring a Staff Full-Stack Engineer, Revenue Systems to lead the development of revenue-critical systems across our Shopify ecosystem, Backend Systems, and Subscription Management. This role will own the architecture and execution of high-impact, in-house builds — including replacing third-party tools like Aftersell and building advanced checkout and post-purchase experiences.

You’ll work cross-functionally with Product, Data, and Growth to translate business requirements into scalable, production-grade systems. This role requires deep Shopify experience and strong full-stack expertise, with a focus on building reliable, high-performance software that directly drives revenue.

This role is part of our remote HQ! We have a fully remote, high-trust work environment - and also come together on a quarterly basis for amazing off-sites where we can connect IRL.

In this role, you will:

• Lead the architecture and development of revenue-critical Shopify applications, checkout extensions, and post-purchase systems.
• Build and scale an in-house revenue tool.
• Design and implement robust backend integrations that safely interact with order management, subscription, and fulfillment systems.
• Develop shared platform capabilities including internal authentication systems, event tracking frameworks, background jobs, and developer tooling.
• Productionize analytics models, optimization logic, and decision engines into user-facing software.
• Own projects end-to-end, from ideation and architecture to deployment, monitoring, and iteration.
• Partner cross-functionally with Product, Data, Growth, and Operations to ensure systems align with revenue and experimentation goals.
• Maintain high standards for performance, reliability, scalability, and developer experience.

We're looking for someone who:

• Has 7+ years of experience in Full-Stack Engineering, Product Engineering, or similar roles.
• Has deep, hands-on Shopify experience (Shopify apps, checkout extensions, post-purchase flows are required).
• Has shipped customer-facing e-commerce features with strong UX and performance standards.
• Has expertise in TypeScript/JavaScript and React.
• Has backend experience in Python and/or Node.js.
• Has built production APIs and services (REST and/or GraphQL).
• Has strong knowledge of authentication patterns, background jobs, and third-party integrations.
• Has experience productionizing analytics models or optimization systems into production software.
• Has experience with cloud infrastructure (preferably GCP), including CI/CD, logging, and monitoring.
• Demonstrates strong systems design and backend integration expertise.

Approach to the role:

• Moves quickly and iteratively while maintaining production-grade quality
• Demonstrates high agency and ownership from concept to post-launch monitoring
• Translates ambiguous requirements into clear technical plans and shipped outcomes
• Collaborates effectively with technical and non-technical stakeholders
• Thinks in terms of business impact, revenue leverage, and long-term scalability
• Balances experimentation velocity with system reliability and order flow integrity
