Java Full Stack With React Jobs in New Haven, CT

At ASSA ABLOY, our mission is to make securely accessing the things in your life noticeably easier, without being noticeable.

As a Full Stack Developer, you will take ownership of our internal design system - a versioned suite of React components, Tailwind configurations, and headless primitives published as NPM packages and used across the organization. You will design clean, reusable, strongly typed component APIs, build highquality product interfaces in React, and contribute to our Laravel backend where needed. You'll collaborate closely with design, product, and backend engineering to deliver interfaces that are accessible, performant, and visually consistent.

A significant portion of this work focuses on CMSdriven marketing and landing experiences. You'll build and integrate designsystem components that empower content authors to assemble pages, and you'll connect those pages to external digital tools and thirdparty services.

This is a frontendleaning role with meaningful fullstack scope. While you spend most of your time in React, you will also consume - and occasionally extend - our Laravel APIs. The role is handson and technically influential: you'll help set architectural direction and mentor other engineers, without direct peoplemanagement responsibilities.

This position will sit on-site in Berlin, CT reporting to the Director of Marketing.

What you will be doing

• Strong JavaScript/TypeScript fundamentals, comfortable in TS strict mode; fluent with type-modeling patterns (discriminated unions, generics, type narrowing) for safe, expressive component APIs
• Deep React: component design and composition, state and data flow, performance; familiarity with a React meta-framework (Next.js)
• Semantic HTML and CSS, with strong Tailwind fluency (utility-first, shared config, design tokens); responsive, accessible UI - WCAG awareness, ARIA patterns, keyboard navigation, focus management, screen-reader/contrast testing
• Component API design: building reusable, well-typed primitives that other engineers depend on
• Design-system & Monorepo workflow: publishing versioned shared packages (Changesets or similar) and orchestrating builds across a monorepo (Turborepo, Yarn/NPM workspaces, or equivalent)
• Rendering & architecture fundamentals: CSR/SSR/SSG/ISR tradeoffs; SPA vs MPA vs hybrid; request/response lifecycle; HTTP caching and CDN behavior
• Comfort in a layered / n-tier codebase: clear separation of concerns, knowing where logic belongs, and the willingness to work across the stack into a server framework
• Client-side data, forms, and routing: fetching and caching, schema validation, client routing
• Third-party integrations: connecting external digital tools and APIs (marketing, analytics, CMS, and similar services) reliably and securely - including script-loading strategy and consent
• Technical vendor assessment: evaluating third-party tools and vendors on technical merits - API quality, integration effort, reliability, and lock-in
• Translating Figma designs into code: faithful, accessible, reusable components from design specs
• Testing strategy: unit/component and E2E, with judgment about what to test where
• CI/CD and containerization: comfort with automated pipelines (GitHub Actions) and Docker-based workflows
• Web performance: Core Web Vitals (LCP, INP, CLS) measurement and remediation
• SEO & structured data: structured data (JSON-LD) and on-page SEO fundamentals; awareness of GEO (generative engine optimization)
• CMS fundamentals: content modeling, authoring workflows, headless vs traditional tradeoffs, static site generators
• Git workflow, code review, and strong async/written communication
