Product Builder

House Sigma, the highest-rated real estate app in Canada, is hiring a Product Builder to take user problems from idea to shipped product, on their own. This is a full-time, permanent role with the flexibility to work from anywhere in Canada.

How We Hire

Before anything else about the role, here’s how we think about who fits  these don’t resonate with you, this likely isn’t the right fit, regardless of how strong your experience is.

Solve problems deeply with ownership, and collaborate to multiply impact.

We think of every challenge at House Sigma as a stone that needs moving. Each person owns their stones end to end, from understanding the problem, to designing the solution, to shipping it. We don’t rely on handoffs to explain stalled progress. We collaborate as a force multiplier, not a dependency chain.

Our Values

The traits we look for in every teammate, and how we evaluate ourselves:

Responsibility and extreme accountability:
We take end-to-end ownership of our projects and follow through, because taking accountability earns trust and freedom.

Deep and independent thinking:
We use first-principles thinking to go beyond surface-level answers, ask the “why” repeatedly, and reason from those fundamentals to get to the truth.

Logical and fact-driven judgment:
We make decisions based on evidence and clear thinking, not assumptions or gut feel.

Judgment and courage:
We act decisively in ambiguity, using sound judgment and the courage to make and own hard calls.

Growth mindset and hard-work appreciation:
We stay curious, keep improving, and respect the consistent effort required to build something great.

Direct, transparent, and constructive communication:
We communicate clearly, give feedback that helps, and say directly to someone the same thing we would say about them.

Superstar and dream-team mindset:
We set a high bar for individual excellence and collaborate in ways that elevate the whole team.

High agency and initiative:
We step up without waiting to be asked, move quickly, and proactively improve processes and outcomes.

Passion and craftsmanship:
We care deeply about the work, treat our role as a craft, and keep refining quality over time.

This Role:
North Star Behaviour Applied to Product

You will own product problems from start to finish: work out what to build, design it, build it with AI coding tools, ship it, and check whether it worked, without handing it off to someone else to design or code. You will work on the House Sigma app and website, and on the internal and partner-facing tools that sit behind them.

You will report to our Director of Product and work closely with our global engineering team, who own the core platform you build on. We are open to people who came up as designers or as product managers, as long as you ship code comfortably today. What matters is that you know your craft properly and you can build.

What “Solve problems deeply with ownership” looks like here

Own product problems end to end: frame the problem, decide the solution, design it, build it and ship it

Write and commit code on top of the House Sigma platform, using AI coding tools as a main part of how you work

Set the success measures for each feature you own and track them yourself

Pull and read data (SQL, dashboards) to decide what to build next and whether a change worked

Talk to users and look at how they use the product to find the next problem worth solving

Work on problems that touch both sides of the platform, consumers and the realtors who serve them, and keep the two consistent

What “Collaborate to multiply impact” looks like here

Work with the global engineering team to flag platform needs early and stay within the agreed product…
