Could It Be

You? We're hiring a Principal Software Engineer who can do more than own the full stack. You'll lead solution design, drive architectural decisions, and write the code that ships. This is a hands-on role: you'll work alongside other senior and principal engineers as peers, everyone pulling their own weight and expecting the same from others.

You design it, you code it, you own it in production. Three days a week you'll be on-site at our North York office, working directly with engineers and product leads across teams. Our team uses AI tools like Cursor or Claude as a core part of how we work, not as optional extras.

This role is for engineers who don't wait to be handed a technical strategy. If you can translate a business problem into an architecture,



own the solution end-to-end, and work closely with engineers and product leads to get it built right, we want to talk. Use Cursor or Claude as part of your daily workflow to accelerate coding, design thinking, reviews, and documentation.

Lead end-to-end solution design for complex initiatives: facilitate technical discovery, define system boundaries, and produce architecture artifacts that the team can build confidently against. Make the hard technical calls across back-end, web, and mobile, then implement them yourself in Type Script – React on the web, React Native on mobile. Architecture is not a document you hand off; it's code you ship.

Work in-person with engineers and product leads to translate requirements into technical strategies, surface trade-offs early, and keep solutions aligned with product direction. Collaborate with other senior and principal engineers to align on architecture, share ownership of hard problems, and hold each other to a high bar. Lead design and architectural reviews, produce technical documentation, and hold yourself to a high bar from first design to production.

So are YOU our next Principal Software Engineer? Active daily use of AI development tools like Cursor or Claude. If you're not already using AI to code, review, and design faster,



this role is not the right fit. ~10+ years of professional software engineering experience with a track record of leading technical initiatives, not just contributing to them. ~ Robust hands-on command of Type Script, with React and React Native (or a documented history of picking up frameworks fast). ~ Ability to communicate technical decisions clearly to both engineers and product leads.

You can go deep on implementation details with a developer and talk trade-offs with a PM without losing either audience. ~ Comfortable with in-person collaboration in North York three days per week.

Experience with Angular or C# /. NET Core. Complex query experience in analytical databases like Big Query or Bigtable. Contributions to open-source or a portfolio that demonstrates architectural thinking, not just shipping velocity. It includes a comprehensive benefits plan and a competitive incentive (bonus) program for Full-Time Permanent roles.
