Senior Software Engineer - Professional Services Engineering

At Shopify, we're making commerce better for everyone, from independent entrepreneurs to global brands. We provide the scalability, reliability, and flexibility merchants need to build, grow, and evolve their businesses. Shopify powers commerce for brands like AllBirds, Gymshark, Staples, and more.

Our Professional Services Engineering team partners directly with these brands through paid engagements to build custom integrations, accelerate product features, and deliver partner solutions that standard approaches can't handle. We bridge the gap between enterprise merchant needs and what Shopify offers out of the box – building apps that connect Shopify systems with merchant systems, payment integrations, sales channels, and custom platform extensions.

This is where Senior Engineers come in, working closely with Plus and enterprise merchants, partners, Delivery Managers, Solution Architects, and Product teams to solve complex challenges. You'll be the primary technical point of contact on your projects, leading both the strategy and hands-on implementation.

What you'll do

• Partner with Plus and enterprise merchants to architect and deliver custom integrations through paid engagements
• Lead technical discovery, solution design, and hands-on implementation for backend systems
• Build apps that connect Shopify with merchant systems (ERPs, fulfillment, inventory, payments, sales channels)
• Collaborate with Product and Engineering teams across Shopify to accelerate backlog features and meet merchant launch timelines
• Develop payment integrations, sales channels, and custom platform extensions for partners
• Investigate and resolve production issues for apps your team owns
• Communicate directly with merchants and partners – set expectations, surface risks early, and land clear recommendations
• Write well-tested code using test-driven development or similar practices
• Share learnings from projects with the team to raise the bar for everyone
• Leverage AI tools (Cursor, Claude, π) to accelerate development and ramp up on unfamiliar codebases

What you can expect

• A hands-on technical role collaborating with high-impact collaborations with merchants and partners
• A fast-paced environment where requirements change frequently and ambiguity is the norm
• Autonomy to solve complex problems creatively, plus mentorship and opportunities to grow from each challenge
• Direct influence on merchant success and Shopify's product roadmap
• Projects typically lasting six months or less – you'll gain broad expertise across many Shopify domains rather than deep specialization in a single area
• A culture that values authenticity, openness, and diverse perspectives

Your skills and experience

We're interested in what you can do. If you're excited about the role, please apply even if your experience doesn't line up perfectly.

Experience can come from formal education, self-directed learning, or previous roles. No specific degree required (skills first).

Technical expertise

• Ruby on Rails: Strong backend development experience, including background jobs, webhooks, and API design
• React: Frontend experience for building admin interfaces and merchant-facing UIs
• Node.js: Familiarity with JavaScript/TypeScript backend services
• GraphQL and REST APIs: Proficiency with Shopify's Admin and Storefront APIs, webhooks, and rate-limit-aware patterns
• Relational databases: Experience with SQL, data modeling, and query optimization
• System integration patterns: Building reliable connections between Shopify and external systems (ERPs, fulfillment, payments)

Development workflow and tooling

• Git/GitHub flows, environments, CI/CD pipelines
• Test-driven development practices
• Proven use of AI tools (Cursor, VS Code/Copilot, Claude, π) to ship production work
• Comfort utilizing AI tools to ramp up on unfamiliar codebases and accelerate development

Communication and collaboration

• Strong communication skills with both technical and non-technical stakeholders
• Ability to translate ambiguous merchant requirements into clear technical solutions
• Comfortable as the primary technical contact for merchants and partners
• Clear written and verbal communication for client-facing engagements
• Thrives in collaborative environments with cross-functional teams (Engagement Managers, Delivery Managers, Solution Architects)

Bonus if you have

• Experience with Shopify app development (public or custom apps), especially react-router
• Familiarity with payment processing, payment app development, or PCI compliance
• Experience with ERP/OMS/PIM integrations
• Background in consultancy or agency work with enterprise merchants
• Experience building internal tools and automation
• Knowledge of Shopify Plus features (B2B, Scripts/Functions, Launchpad)

How you'll work

You'll work on projects typically lasting six months or less, from hands-on delivery to technical leadership on the engagement. You'll work in a dynamic environment where priorities shift frequently, requirements evolve, and creative problem-solving is essential.

This role requires both deep technical execution and the ability to think strategically about merchant outcomes. You'll be expected to learn new frameworks and codebases quickly – and AI tools are your accelerator, not a crutch.

*At Shopify, we pride ourselves on moving quickly—not just in shipping, but in our hiring process as well. If you’re ready to apply, please be prepared to interview with us within the week. Our goal is to complete the entire interview loop within 30 days. You will be expected to complete a pair programming interview, using your own IDE.

This role may require on-call work. Ready to craft your next masterpiece in code? Join the team that’s making commerce better for everyone.*
