Full Job Description

We are Subway Headquarters! A dedicated team of professionals supporting thousands of franchisees around the globe.

Sr. Software Engineer - Mobile App Shelton, CT
Ready to build what’s next with one of the world’s most iconic brands?
Why Join Subway?
At Subway, we are not standing still. We are building.
This is a business focused on what matters most: growing franchisee profitability, strengthening our brand and creating long-term value. The people who thrive here are the ones who want to make a real impact.
You will not just do the work. You will shape it.
We move fast. We think like owners. We make decisions that matter. We hold ourselves to a high standard because what we do directly impacts thousands of franchisees around the world.
If you bring energy, accountability and a bias for action, you will fit right in.
We take the work seriously, but we also know the best results come from teams that support each other, celebrate wins and show up ready to build something better every day.
This is your chance to be part of what’s next.
ABOUT THE ROLE

We're looking for an experienced mobile engineer to help build and improve the Subway app on iOS and Android — the app millions of guests use to order food, manage their loyalty rewards, find nearby restaurants, and check out with their preferred payment method.
You'll work in a collaborative product team alongside designers, product managers, and other engineers, shipping features that are fast, reliable, and polished. App performance is a core priority: every change is expected to maintain or improve speed metrics we track rigorously.
TECH AT A GLANCE

Our mobile stack in plain terms:
Framework React Native (cross-platform iOS & Android) + Expo
Language TypeScript (strict mode) — strongly typed throughout
State Management Redux Toolkit for app-wide state; MMKV for fast local storage
Navigation React Navigation
Payments Adyen, Apple Pay, Google Pay
Auth AWS Cognito (token-based login/session management)
Testing Jest, React Native Testing Library, Maestro (end-to-end)
CI/CD GitHub Actions, Expo Application Services (EAS), Fastlane
Error Tracking Sentry
Feature Flags LaunchDarkly (controls which features are live for which users)
Analytics Adobe Experience Platform, Quantum Metric

WHAT YOU’LL DO

Build and maintain app features across the full stack of the mobile experience — ordering, menu, cart, checkout, payments, loyalty, and store locator.
Write clean, well-tested TypeScript following our established coding standards, with automated checks (linting, formatting, architectural boundary rules) running on every commit.
Connect the app to backend services and third-party tools: our ordering API, authentication, payment processors, fraud detection, feature flags, and analytics.
Work with product managers, designers, and backend engineers to turn requirements into working software — joining sprint planning and reviews, implementing against Figma designs, aligning on API contracts.
Review code from teammates and incorporate review feedback on your own pull requests; all PRs go through CI checks and peer review before merging (no direct pushes to main).
Debug and fix issues on both iOS and Android using crash reporting tools, native logs, and device/simulator builds.
Write and maintain tests — unit, component, performance (we track render and time-to-interactive budgets), and end-to-end flows tested on real devices via BrowserStack.
Help keep our build and release pipelines healthy: automated builds, beta testing distributions, and production releases to the App Store and Google Play.
Document your work — code comments, architecture decision records, and notes in our project management system.
Participate in Agile ceremonies: standups, sprint planning, refinement, and retrospectives.
Stay current with the React Native ecosystem and contribute to team-wide improvements, including our ongoing migration to the React Native New Architecture (better performance and native integration).

WHAT WE’RE LOOKING FOR
Required:

6–9 years of professional software engineering experience.
Strong commercial experience building cross-platform mobile apps with React Native and TypeScript.
Solid understanding of React Native architecture: state management (Redux), navigation, performance optimization, and local storage.
Experience calling REST APIs and working with token-based authentication flows.
Familiarity with the native side of React Native — iOS (Swift/Objective-C) and Android (Kotlin/Java) builds, native modules — or genuine enthusiasm to learn.
Practical experience with mobile testing: unit tests, component tests, and end-to-end flows.
Experience shipping apps to the App Store and/or Google Play.
Clear communicator who works well in a collaborative, cross-functional team.
Bachelor’s degree in Computer Science, Engineering, or a related field — or equivalent hands-on experience.

Nice to have:

Payment integrations (Adyen, Apple Pay, Google Pay).
Feature flag systems (e.g., LaunchDarkly).
Mobile analytics or error tracking (Sentry, Adobe Experience Platform, Quantum Metric).
CI/CD for mobile: GitHub Actions, Expo EAS, Fastlane, BrowserStack.
Internationalization (i18n) and multi-language app support.
Privacy and consent frameworks (e.g., OneTrust).
SSL/certificate pinning for mobile API security.

HOW WE WORK
We use Agile delivery in two-week sprints, tracked in Azure DevOps. Design specs come from Figma. Architecture decisions and technical docs live alongside the code in the repository. We value code quality, thoughtful review, and incremental improvement over big-bang rewrites.
Pull requests go through automated CI checks (tests, linting, build validation) and at least one peer review before merging. We treat the CI pipeline as a quality gate, not a formality.

What do we offer?

Insurance Plans (Medical, Life)
Pension/401K/RSP (country specific)
Competitive Bonus
Mobility Allowance
Tuition Reimbursement
Company Holidays
Volunteering time
And More…..

Compensation: The base pay range for this role is $119,200 - $149,000 annually
Pay within this range will be determined in good faith based on job-related factors, which may include skills, experience, education/training, location, and internal equity.

The Company is only considering applicants who are currently authorized to work in the country the position is based. AA/EOE/D/V
