What is a full stack development intern?

A Full Stack Development Intern is a student or recent graduate who assists with building both the front-end (client side) and back-end (server side) components of web applications. They typically work under the supervision of experienced developers to learn and contribute to projects using various programming languages and frameworks. Responsibilities may include writing code, debugging, testing, and collaborating with design and development teams. This internship provides practical experience in the entire web development process and helps prepare interns for a career as a full stack developer.

What kinds of projects and technologies does a full stack development intern typically work on during their internship?

Full Stack Development Interns often contribute to both front-end and back-end features of web applications, working with frameworks like React or Angular for the user interface and Node.js, Python, or Java for server-side logic. Interns may be assigned tasks such as building new components, fixing bugs, writing APIs, or assisting with database integration. It's common to collaborate closely with designers, senior developers, and QA testers in an agile environment, gaining exposure to the entire software development lifecycle. This hands-on experience helps interns understand how different technologies interact and prepares them for more advanced roles in the future.

What are the key skills and qualifications needed to thrive as a full stack development intern, and why are they important?

To thrive as a Full Stack Development Intern, you need foundational knowledge of front-end and back-end programming languages such as JavaScript, HTML, CSS, and at least one server-side framework, alongside a relevant academic background in computer science or a related field. Familiarity with version control systems like Git, databases (SQL/NoSQL), and cloud platforms is often expected, and experience with tools like React, Node.js, or Docker can be advantageous. Strong problem-solving skills, adaptability, and effective communication help interns collaborate within teams and learn quickly in dynamic environments. These skills and qualifications are crucial for efficiently contributing to diverse development tasks and succeeding in fast-paced tech teams.

Job description

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 high-quality 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 CMS-driven marketing and landing experiences. You'll build and integrate design-system components that empower content authors to assemble pages, and you'll connect those pages to external digital tools and third-party services.
This is a frontend-leaning role with meaningful full-stack scope. While you spend most of your time in React, you will also consume - and occasionally extend - our Laravel APIs. The role is hands-on and technically influential: you'll help set architectural direction and mentor other engineers, without direct people-management 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

What we are looking for
  • Bachelor's Degree in Computer Science or Engineering and/or a High School Diploma/GED required.
  • Minimum of 5 years of professional full stack development experience with a strong focus on front end UI skills.
  • Must have strong hands-on experience with Tailwinds and React.js to be considered.
  • Must demonstrate a solid foundation of HTML, CSS, JavaScript, HTTP, and Restful APIs.
  • Must have hands-on coding experience in PHP.
  • Must have backend development skills using SQL or SQL Databases.
  • Experience architecting and shipping backend RESTful APIs using Node.js.
  • Experience with DevOps and working with cloud platforms.
  • Familiarity with front-end and backend performance Best Practices.
  • Experience with common software development tools and processes.
  • Proficiency in Microsoft Office tools.

Preferred Skills:
  • Adobe Experience Manager (AEM): Component development across Maven modules, authoring dialogs, clientLibs, Dispatcher, Apache Sling Models (Java), JCR/Oak.
  • Experience leading a development team or acting as a tech lead
  • MarTech & analytics tooling: GTM, GA4, cookie consent (OneTrust), Search Console
  • Server framework experience: Laravel/PHP or equivalent
  • DevOps breadth beyond pipelines: serverless vs server-based, DNS/CDN, secrets management
  • Observability awareness: error tracking (Sentry), APM, structured logging

  • Continuous professional development opportunities and an environment that fosters internal growth and mobility.
  • Competitive compensation and benefits package which includes multiple healthcare options, tuition reimbursement, and matching 401k.
