Senior Software Engineer (React Native)

The Role

We're hiring a Senior Software Engineer specializing in React Native development for our customer-facing mobile app, built and shipped in tandem with work on the Straight Arrow website. You will own the mobile codebase end-to-end — from the React Native and Expo layer all the way down to native bridges we've already built into iOS and Android.

This is a deeply hands-on role. We're looking for an engineer whose primary impact is the code itself: the architecture you choose, the patterns you set in the codebase, the bugs you don't ship, the bar you hold in code review. But you'll also be a force multiplier for the entire engineering team, partnering with product, design, QA, and our web engineers to turn complex problems into shipped products.

If you're a strong senior engineer who's also been the person teammates lean on for technical direction, code review, mentorship, and 'let me show you how I'd approach that,' this role is built for you.

What You'll Do

• Build new experiences that delight customers.
• Own architecture and day-to-day development of our React Native / Expo mobile application.
• Partner closely with our API engineers, not as a downstream consumer, but as a co-author of requirements and contracts.
• Work side-by-side with the web engineering team to ship cohesive, parallel experiences across platforms; coordinate shared patterns, shared concerns, and shared deadlines.
• Collaborate daily with product, design, and QA to translate ambiguous customer problems into clean, shippable solutions.
• Set the technical bar for the mobile codebase through architecture, code review, testing strategy, performance work, accessibility, and release engineering.
• Mentor and uplevel other engineers and act as a force multiplier rather than a single point of throughput.
• Drive technical decisions with a relentless customer focus: what we ship has to work, in the real world, on real devices, for real users.

What We're Looking For

• 10+ years of professional software engineering experience, with substantial recent experience in React Native development.
• Deep, demonstrated expertise with React Native across both iOS and Android, including the practical realities of cross-platform development (platform differences, native modules, performance, app store release processes).
• Hands-on experience using Expo as a development platform - managed workflow, EAS Build / Submit / Update, and the tradeoffs involved.
• Ability to write and maintain native bridges - comfort dropping into Swift/Objective-C and Kotlin/Java when needed.
• A strong customer focus, with a track record of building customer-facing enterprise applications that real people depend on.
• Experience working with an API, helping define requirements, shape contracts, and contribute to implementation decisions.
• Demonstrated technical leadership as a senior IC: setting architectural direction, raising code quality through review and example, and helping less-senior engineers grow.
