About BrainyYack

Founded in 2006, BrainyYack is a technology, AI, and digital product consultancy headquartered in Toronto. For nearly two decades, we have partnered with growth-focused and enterprise organizations to design and deliver the software, AI systems, and digital experiences that move their businesses forward.

Our work spans custom software engineering, intelligent AI agents and automation, scalable platforms, and enterprise digital transformation. We specialize in turning fragmented, underused data into structured, intelligent systems, enabling clients to operate with greater speed, efficiency, and measurable return, without disrupting what already works. Across financial services, retail, healthcare, education, manufacturing, and more, organizations trust us to bring complex, high-stakes ideas to life.

At our core, we are a firm where engineering excellence, creativity, and genuine business impact meet, and where the people who build with us do work that reaches real users and real outcomes.

The people who thrive here

We look for professionals who take ownership of their work, hold a high bar for quality, and care about the outcome a client is trying to achieve, not just the task in front of them. Our strongest people are clear communicators who work well directly with clients, perform across multiple projects, and bring both craft and judgment to everything they build.

About the Opportunity

We are hiring a Senior Full-Stack Developer to design and build web applications and platforms across our client projects. You will own work from architecture through delivery, turning business problems into reliable, high-quality products, often across more than one project at a time.

What we’re looking for

• You have built and shipped full-stack web applications in production, end to end
• You own your work and can manage more than one project at once
• You hold a high bar for quality, performance, and maintainability
• You can work directly with clients and explain technical trade-offs clearly
• You thrive in a distributed, collaborative team

Application Requirements

Please include:

• An updated résumé / CV, plus your portfolio, GitHub, or links to live projects.

If you like owning real products end to end and shipping work that lasts, we would love to hear from you.
