What is a full stack web developer internship?

A Full Stack Web Developer Internship is a temporary position designed for students or recent graduates to gain practical experience working on both the front-end and back-end aspects of web development. Interns typically work with technologies such as HTML, CSS, JavaScript, and frameworks like React or Node.js. The role involves collaborating with teams to build, test, and maintain web applications, allowing interns to develop coding skills and understand the software development lifecycle. This internship is a valuable opportunity to apply classroom knowledge in real-world projects and prepare for a career as a full stack developer.

What types of projects can I expect to work on during a full stack web developer internship?

As a Full Stack Web Developer Intern, you can expect to work on a variety of projects that span both front-end and back-end development. This often includes building or improving features for web applications, debugging code, writing unit tests, and collaborating with designers and other developers to deliver user-friendly products. You may also participate in code reviews, assist with database integration, and learn about deployment processes. These experiences give you a comprehensive view of the software development lifecycle and prepare you for more advanced roles in the future.

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

To thrive as a Full Stack Web Developer Intern, you need a solid understanding of front-end and back-end programming languages (such as HTML, CSS, JavaScript, and at least one backend language like Python, Java, or Node.js), along with coursework or experience in web development. Familiarity with frameworks (like React or Angular), version control systems (such as Git), and databases (SQL or NoSQL) is typically expected. Strong problem-solving abilities, attention to detail, and effective communication skills help you learn quickly and collaborate within development teams. These competencies are crucial for efficiently contributing to real-world projects and adapting to the fast-paced nature of modern web development environments.

Web Developer
 
Location: Ontario (Hybrid - See “Hybrid Work Details” section below for more information)
Position Type: Full-Time 
Vacancy Status: This posting is for an existing vacancy.
 
About Us
Voices is the trusted voice partner for brands, tech and voice talent. Voices helps scale real voice solutions, across traditional voiceover, Voice AI, and ethically sourced voice data. For more than two decades, the biggest and most beloved brands have trusted Voices to find their voices and bring their projects to life.
 
Why join us? We’re on a mission to shape the future of voice, and we’re building a team that’s curious, collaborative, and passionate about making great ideas heard.
 
About the Role  
As a Web Developer, you’ll join a high-performing development team organized into cross-functional teams and focused on building and evolving modern full-stack web applications that directly support our customers and internal teams. You’ll work primarily with modern PHP, JavaScript/Node.js, CSS, and databases to build systems used every day across the business. Your work will be visible, meaningful, and impactful.
 
We care deeply about quality, steady delivery, and continuous improvement. You’ll collaborate with Product, Infrastructure, QA, and Support to deliver well-tested, maintainable solutions, take ownership of the features you build, and help improve the systems you work on. You’ll report to the Manager, Application Development and be part of a team that values high standards, practical problem solving, and strong collaboration.
 
Responsibilities  
In this role, you’ll take ownership of the following key areas:
 
Application Development
  • Build and maintain customer-facing and internal user interfaces using HTML, CSS (LESS/SASS), JavaScript, and React.
  • Develop and extend applications using modern PHP frameworks (e.g., Laravel) and supporting scripts.
  • Design, build, and maintain internal APIs and third-party integrations (e.g., Salesforce and cloud services across AWS and GCP).
  • Build new product features and pages, taking ownership of the areas you develop from implementation through deployment and follow-up.
Quality, Testing & Security
  • Write and maintain automated tests (unit and integration) to ensure code quality and reliability.
  • Apply accessibility (AODA, WCAG) and security (OWASP) best practices to deliver inclusive and secure applications.
  • Test, optimize, and improve application performance, identifying and resolving bottlenecks.
  • Review and triage support issues, debug and resolve defects, and collaborate with Product and Support teams.
Development Practices & Delivery
  • Write and maintain database migration scripts and support release planning in collaboration with QA and Product teams.
  • Contribute to build tooling and development workflows, suggesting improvements where appropriate.
  • Work within established Git workflows, actively participating in code reviews by submitting and reviewing pull requests.
  • Use AI-assisted development tools responsibly to improve productivity, code quality, and documentation.
Documentation & Collaboration
  • Document technical decisions, APIs, and implementation details.
  • Contribute to and help maintain shared libraries, including our internal component library and design system.
 
What You Bring
We’re looking for someone who brings some or all of the following:
  • You want to ship regularly. Your passion is to build end-to-end software. You always want to improve and learn.
  • You understand the importance of quality code. Your code is documented, understandable and predictable. Tests are written with confidence.
  • You’re comfortable with a varied and modern stack. You have production-level experience in PHP, JavaScript/Node.js, React, and SQL, and containerized workloads.
  • You have experience writing and maintaining build, migration, and automation scripts to support development and deployments.
  • You’re familiar with cloud computing fundamentals (e.g., queues, background jobs, caching, object storage) and how they support reliable web applications.
  • You can explain your thinking. You are able to communicate your ideas or issues well.
  • Your goal is to build for everyone. You are skilled in developing both front-end and back-end solutions from scratch to create valid, reusable, performant, and accessible systems.
  • You are self-motivated and can work independently. You take the initiative to make sure that you have everything you need and will call for support when required.
  • You love learning. You thrive on solving problems, learning new tricks, bridging the gaps between new and old, and want to keep getting even better.
  • You love sharing. Helping your team based on your experience is time well spent.
  • You have 3+ years experience in database-driven web application development.
  • You earned a BS or MS in Computer Science, Diploma in Web Development or have the equivalent work experience.
 
Perks & Benefits
In addition to competitive compensation, we offer a range of perks that support your growth, wellbeing, and day-to-day flexibility. Here’s what you can look forward to: 
  • Generous Vacation: We offer 15 days of annual vacation (pro-rated for your first year), plus additional paid leave during our scheduled summer and winter holiday closures.
  • Personal Time: Take care of what matters with 5 paid personal days and 3 unpaid personal days annually
  • Comprehensive Health Coverage: Access to health and dental benefits after just 3 months of employment
  • Hybrid Flexibility: Enjoy the best of both worlds with our hybrid work environment
  • Performance Bonus Program: Recognizing your impact with bonus opportunities tied to company and individual performance
  • Learning & Development Support: We invest in your growth with a dedicated L&D budget and coverage for platforms like LinkedIn Learning, Udemy, Codecademy, and more
