Role Overview: As a Senior Shopify Engineer, you will bridge the gap between business requirements and technical architecture. You will collaborate closely with Lead Architect to contribute to technical discovery sessions, design custom integrations for Shopify Plus merchants, and own the development of the most complex platform features. A core part of this role involves technical leadership: you will navigate the solution path for complex projects, groom technical stories, and delegate specific implementation tasks to the Shopify Engineering team.

Key Responsibilities:

• Collaborative Discovery: Work alongside the Architect during client-facing discovery sessions to identify technical risks and opportunities. Use your depth of experience to guide conversations and translate merchant needs into robust technical roadmaps.
• Advanced Development: Act as the primary developer for the most difficult and nuanced project components. You are expected to be hands-on, developing complex solutions rather than simply handing off designs.
• Backlog Grooming & Handoff: Define technical tasks and specifications for Shopify Engineers. Groom user stories into actionable development tasks, providing the necessary technical context for the base engineering team to succeed.
• Solution Architecture: Contribute to the technical design of enterprise-scale Shopify Plus stores, making critical decisions on theme architecture vs. custom app builds vs. third-party integrations.
• Advanced Integrations: Architect and implement secure connections between Shopify and enterprise systems (ERPs, CRMs, OMS, and PIMs) using GraphQL and REST APIs.
• Shopify Plus Mastery: Spearhead the implementation of advanced Plus features, including Checkout Extensibility, Shopify Functions, B2B logic, and complex metaobject architectures.
• Performance & Security: Support and help drive the end-to-end performance strategy and security posture for high-volume stores, ensuring scalability during peak traffic events (Black Friday/Cyber Monday).

Required Skills & Experience:

• 5+ years of professional frontend or full-stack experience, with at least 3 years dedicated to the Shopify platform.
• Advanced Platform Knowledge: Expert-level mastery of Shopify Plus, including its limitations and extensibility points.
• API Expertise: Deep experience with the Shopify GraphQL Admin API and Storefront API.
• Backend Proficiency: Ability to build and maintain custom Shopify apps (Node.js/Remix or similar) or middleware when off-the-shelf solutions are insufficient.
• Modern Tooling: Expertise in Shopify CLI, CI/CD pipelines for commerce, and advanced Git workflows.
• Strategic Problem Solving: Proven track record of solving non-standard commerce problems that require moving beyond Liquid templates.
• Technology Selection: Ability to articulate the trade-offs between different technical approaches (e.g., Headless vs. Hydrogen vs. Liquid-first) to both internal teams and clients.
• Problem Finding: A proactive approach to identifying technical debt or performance bottlenecks before they impact the merchant’s bottom line.
• Leadership & Delegation: Strong ability to break down complex project goals into actionable tasks for other developers.
• Client Consultation: Excellent communication skills to lead technical discussions with enterprise-level stakeholders.
• Decision Making: Confidence in making high-stakes technical choices and standing by them under project pressure.

In return we offer:

• The friendliest community of like-minded IT people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program is designed to meet our team’s needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort, and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups
