Principal Solutions Architect (Front-End Focused)
We’re looking for a Principal Solutions Architect with a strong Front-End focus to lead the technical direction of high-traffic, headless e-commerce projects for major retail brands.
This is not a general software architect role. We specifically need an experienced e-commerce architect who can own front-end architecture, web performance, and technical direction across distributed engineering teams and client engagements.
Location: Europe, LATAM, or Canada.
Tools: React, Next.js, TypeScript, Shopify Plus / Salesforce Commerce Cloud / Big Commerce / SCAYLE, Vercel, CI/CD pipelines, Cursor and/or Claude Code, ChatGPT, Jest, Cypress, Playwright, Slack, Jira, Confluence.
Responsibilities:
Own scalable front-end architecture using Next.js, React, and TypeScript for enterprise e-commerce projects.
Lead decisions around rendering, state management, data fetching, caching, CDN, and performance.
Translate business requirements into architecture roadmaps and actionable user stories with acceptance criteria and technical dependencies.
Work directly with clients, explain architectural trade-offs, and resolve ambiguity before development.
Provide technical direction to distributed teams and address architectural drift.
Establish architecture standards, ADRs, coding conventions, and technical documentation.
Drive Core Web Vitals and measurable web performance improvements.
Define specifications and technical context that enable both engineers and AI agents to deliver reliable, reviewable code.
Requirements:
3+ years leading front-end architecture and technical direction for distributed engineering teams.
Strong enterprise e-commerce experience — mandatory. Experience architecting solutions with Shopify Plus, Salesforce Commerce Cloud, BigCommerce, or a similar enterprise commerce platform.
Deep expertise in React, TypeScript, and modern Next.js, including App Router and React Server Components.
Strong knowledge of SSR, caching, CDN/edge delivery, serverless patterns, and modern web architecture.
Proven production experience improving Core Web Vitals (LCP, CLS, INP) with measurable results.
Experience communicating architectural decisions and trade-offs to clients and non-technical stakeholders.
Strong spoken and written English.
Experience with AI-assisted/agentic engineering beyond personal AI tool usage — writing specifications, acceptance criteria, documentation, and technical context that AI agents can reliably execute against.
Nice to Have:
Headless commerce architecture experience.
Shopify Storefront API, SFCC Composable Storefront, BigCommerce, or similar.
Headless CMS: Contentful, Sanity, Contentstack.
Vercel, CI/CD, Jest, Cypress, or Playwright.
What We Offer:
Competitive compensation and benefits package.
Fully remote position with a distributed, async-first team.
Opportunity to shape the architecture of high-traffic commerce platforms for major retail brands.
Direct collaboration with clients and experienced engineering teams.
