Senior Principal Software Developer, Mobile Platform

You'd be joining our Mobile Platform team within the Platform Engineering division.

We're building an AI-native platform for our internal developers, over 150 of them, guided by a single question: does this shorten the time from idea to value, for the teams building on our platform and for the customers they ultimately serve?

The smooth path is the safe, fast path, because the platform makes it the default. We build the route that maximizes AI acceleration.

You'll shape the technical direction for how Mobile features get built, shipped, and operated across the engineering org, not just for one team.

What you’ll do

• Define and drive the multi-year technical strategy, governance and architecture for our mobile platform, balancing near-term developer pain with long-term scalability.

• Design and build critical foundations and tooling that power our Mobile app, and set the bar for quality through hands-on contributions to the hardest problems.

• Lead the consolidation and evolution of platform primitives: SDKs, CI pipelines, build tooling, release trains, observability, and agentic development golden paths.

• Champion AI-native ways of working, embedding AI workflows into your own practice, into the platform, and into how our feature teams build and ship.

• Raise engineering excellence standards across the organization through architectural reviews, RFCs, and technical mentorship of senior engineers and tech leads.

• Partner with Platform Engineering managers across multiple teams to set priorities, shape roadmaps, and align on cross-team technical direction.

• Define success metrics for the platform (adoption, build times, release velocity, developer satisfaction) and use them to guide investment and communicate impact.

• Present technical priorities, trade-offs, and results to executive stakeholders, and collaborate daily with engineering leaders across the company.

About you

• 10+ years of software engineering experience, including significant experience in mobile engineering, with a track record of technical leadership at the staff, principal, or equivalent level.

• A strong AI-native mindset. You've brought AI-assisted workflows into a platform or org, not just your own workflow.

• Deep expertise in React Native, including its architecture, performance, and native integration (iOS and Android).

• Proven success designing and driving adoption of shared modules, SDKs, and reusable components used across many teams.

• Strong expertise in Mobile foundations: CI/CD, build systems, release management, code signing and distribution, and mobile observability.

• A history of influencing technical direction across teams and organizations without relying on formal authority, including leading cross-team initiatives from proposal to adoption.

• A product mindset toward internal platforms: you understand your customers, measure adoption, and make pragmatic build-vs-buy decisions.

• Excellent mentorship and communication skills, with the ability to coach senior engineers and translate complex technical topics for executive audiences.

• Expert-level English, spoken and written, as you’ll lead platform engineering managers across multiple teams, present technical priorities to executive stakeholders, and align daily with engineering leaders outside Québec.
