Full Stack Development Intern information

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 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 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

Our new progressive work model is called PinFlex, a term that's uniquely Pinterest to describe our flexible approach to living and working. Visit our PinFlex landing page to learn more. 

We are looking for inquisitive, well-rounded Full-stack engineers to join our Monetization engineering teams. Working closely with product managers, designers, and backend engineers, you'll play an important role in enabling the newest technologies and experiences. You will build robust frameworks & features. You will empower both developers and Pinners alike. You'll have the opportunity to find creative solutions to thought-provoking problems. Even better, because we covet the kind of courageous thinking that's required in order for big bets and smart risks to pay off, you'll be invited to create and drive new initiatives, seeing them from inception through to technical design, implementation, and release.

What you'll do:

  • Own UI development lifecycle for our monetization products: designing, architecting, and shipping ad-creation flows that power new AI-powered ad formats
  • Build out full-stack Pinner-facing features to power the future of inspiration on Pinterest
  • Contribute to and lead each step of the product development process, from ideation to implementation to release; from rapidly prototyping, running A/B tests, to architecting and building solutions that can scale to support millions of users
  • Partner with design, product, and backend teams to build end-to-end functionality
  • Put on your Pinner hat to suggest new product ideas and features
  • Employ automated testing to build features with a high degree of technical quality, taking responsibility for the components and features you develop
  • Grow as an engineer by working with world-class peers on varied and high impact projects

What we're looking for:

  • 4+ years of industry full-stack development experience, building consumer or business facing products
  • Proven ability to build scalable web UIs using React, Typescript, Redux, GraphQL, and REST APIs
  • Comfortable architecting and building scalable web UIs with React, Typescript, Redux, GraphQL and REST APIs
  • Proficiency in one or more common frontend and fullstack tech stacks: e.g. Javascript, React, API, storage, caching and data processing.
  • Experience in following best practices in writing reliable and maintainable code that may be used by many other engineers
  • Ability to keep up-to-date with new technologies to understand what should be incorporated
  • Strong collaboration and communication skills
  • Bachelor's or Master's degree in a relevant field such as Computer Science, or equivalent experience

Relocation Statement:

  •  This position is not eligible for relocation assistance. Visit our PinFlex page to learn more about our working model.

In-Office Requirement Statement:

  • We let the type of work you do guide the collaboration style. That means we're not always working in an office, but we continue to gather for key moments of collaboration and connection.
  • This role will need to be in the office for in-person collaboration 1-2 times per half and therefore can be situated anywhere in Ontario.
