Job description
We're hiring a Principal Software Engineer who can do more than own the full stack. You'll define how it's built, and then build it yourself. 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, Claude, and Gemini as a core part of how we work, not as optional extras. You're expected to use them daily to move fast, stay sharp, and deliver at a high standard.
This role is for engineers who don't wait to be handed a technical strategy. They write it. 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.
You'll have real authority over technical direction, not an advisory seat. You'll work with a team that ships frequently, takes AI tooling seriously, and treats engineering judgment as a first-class input into product decisions. If you want to work at a level where the architecture you design is the architecture that gets built, we want to talk.

- Use Cursor, Claude, and Gemini as part of your daily workflow to accelerate coding, design thinking, reviews, and documentation. Always looking for ways to go faster without cutting corners.
- 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 C# / .NET, Angular / TypeScript, and React Native. 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., * Active daily use of AI development tools like Cursor, Claude, and Gemini. This is a hard requirement. If you're not already using AI to code, review, and design faster, this role is not the right fit.
Requirements
- 10+ years of professional software engineering experience with a track record of leading technical initiatives, not just contributing to them.
- Demonstrated experience leading solution design for complex systems: facilitating architecture sessions, producing design documentation, and driving teams from ambiguity to executable plans.
- Strong hands-on command of C# / .NET / ASP.NET Core and TypeScript, with experience in Angular and React Native (or a documented history of picking up frameworks fast).
- Deep practical knowledge of Domain-Driven Design (DDD) and Event-Driven Architecture (EDA) applied in real production environments.
- 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. This role requires presence, not just availability.
_Kudos if…
_
- Experience with real-time technologies like WebSockets, gRPC, or Firebase.
- Hands-on with Google Cloud Platform (GCP), our cloud environment.
- Complex query experience in analytical databases like BigQuery or Bigtable.
- Contributions to open-source or a portfolio that demonstrates architectural thinking, not just shipping velocity.
Benefits & conditions
- Health & wellbeing resources and programs
- Paid vacation, personal, and sick days for work-life balance
- Competitive compensation and benefits packages
- Work-life balance in a hybrid environment with at least 3 days in office
- Career growth and development opportunities
