Overview
Instacart’s Transaction Platform team builds the shopper checkout experience, powers seamless and secure payments, and operates the point-of-sale intelligence system that detects and corrects order discrepancies in real time. We’re looking for a Senior Mobile Engineer (iOS) to help craft best-in-class mobile experiences that make every shopper faster, more accurate, and more successful.
In this role, you’ll partner closely with product, design, data science, backend, and Android engineers to deliver features across checkout, payments integrations, and OCR-driven workflows. You’ll shape the iOS strategy for the team, influence technical direction across codebases, and ship high-quality, observable software at scale. This role is remote within Canada and joins a collaborative team of 15 focused on high-impact work that keeps our marketplace thriving.
We value clear communication, practical problem solving, and ownership. If you thrive in a fast-paced, evolving environment where you can roll up your sleeves, make thoughtful tradeoffs, and see your work move key metrics, you’ll feel right at home here.
About the Job
- Own the iOS roadmap for the Transaction Platform team—partnering with PM and Design to define what we build and why, identifying opportunities (including where AI can add leverage), and steering the strategy rather than only executing it.
- Deliver features end to end: technical design and clean architecture, implementation, phased rollout, observability to confirm impact, and on-call/incident response when needed.
- Make sound product-technical tradeoffs—balancing complexity, customer value, timelines, and risk; decide when to prototype vs. build for the long term; and verify that launches move the right metrics.
- Continuously improve the codebase—reduce tech debt, modernize legacy components, and create reusable abstractions that accelerate development for the entire iOS surface area.
- Serve as the primary iOS point of contact across partner teams—unblock integrations, uphold best practices, and provide guidance on architecture, performance, and platform conventions.

- Hands-on experience applying MVI or MVVM architecture patterns in a production codebase.

- Experience with modular iOS architecture (e.g., multiple local frameworks/packages, protocol-based dependency injection).
- Demonstrated technical leadership, such as owning a team roadmap or multi-quarter initiative and mentoring junior engineers.
- Strong debugging and analytical skills with a track record of resolving complex production issues.
- Clear written and verbal communication skills; comfortable with code reviews and cross-functional collaboration.

- Experience working cross-platform with iOS and Android partners and codebases.
- Experience leading refactors or modernization efforts in an established mobile codebase.
- Experience introducing AI-driven development practices or tooling to improve developer velocity and quality.
- Experience with iOS testing frameworks and approaches, including Quick/Nimble (BDD) and snapshot testing.
- Experience with local storage solutions such as GRDB or other SQLite abstractions.
- Experience with Apple Pay/PassKit or other payments and checkout integrations.
