• Work directly with our CEO, CTO, and a handful of other engineers to build full stack features and improvements to the product • Work across the entire stack using cutting edge frameworks, tools, and own execution • Take true end-to-end ownership of your work and lead key components of our product roadmap • Refine the SDLC & CI/CD pipelines • Maintaining our AWS infrastructure

• Build and evolve high‑performance C++ systems that sit at the core of the platform, with a focus on keeping them stable, maintainable, and built to last. • Get hands‑on with performance work, understanding how the system behaves in production, identifying bottlenecks, and optimising code and memory where it matters most. • Tackle complex technical problems in a large, distributed environment, using sound judgement to arrive at practical, reliable solutions. • Work closely with a cross‑functional team—other C++ engineers, QA, architects, analysts, and product owners—to deliver end‑to‑end solutions and help shape technical decisions along the way. • Deliver reliably as part of a self‑managed Agile team, balancing new feature work with the ongoing health and reliability of existing systems. • Help raise the engineering bar by contributing to DevOps practices, using modern and AI‑assisted tooling, and mentoring junior developers through guidance and thoughtful code reviews.

• Architect and build the core systems that ensure Stay operates seamlessly within Shopify’s ecosystem to serve hundreds of subscription brands and millions of subscribers. • Partner closely with Product, Design, and Engineering to deliver reliable, maintainable, and performant solutions that set us apart in the subscription ecosystem. • Redesign the webhook processing architecture to support 10x growth. • Architect a new abstraction layer that decouples internal subscription models from Shopify order primitives. • Lead a technical deep-dive on Shopify GraphQL bulk operations and performance tradeoffs. • Write an RFC defining the next generation of Stay’s integration framework. • Review critical infrastructure PRs and guide engineers on distributed systems design. • Implement new APIs and services to unlock the next generation of subscription management and analytics features for merchants. • Design and develop internal tooling when you see opportunities to better enable yourself and other engineers. • Collaborate with your teammates on Eng, Design and Product Management to plan and execute on new projects.
