Job description

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
  • Community Impact: We empower you to give back with 8 hours of paid volunteer time annually, allowing you to support the causes and nonprofits that matter most to you.
  • A Great Team: Work with genuinely kind, smart, and talented people who love what they do (and know how to have fun doing it).
Hybrid Work Details: We are a hybrid workplace, allowing employees to work remotely from home. However, this position requires one in-office day per month on pre-set dates, during which all company employees are expected to attend. Our office is located at 100 Dundas Street, London, Ontario. Additionally, you may be asked to come into the office as needed with reasonable notice.
Compensation
Salary Range: $80,000 - $105,000
A typical hire for this role generally falls between the minimum and midpoint of the range based on skills, experience, qualifications and internal equity. Employees grow through the range based on performance and demonstrated competencies.
