Software Engineer, iOS / Android (SF/NYC/Remote)

About Persona

We’ve built Persona to support practically every use case and industry — that’s why we’re able to serve a wide range of leading companies. For example, Instacart relies on Persona to verify shoppers who onboard onto their platform before delivering groceries to your doorstep. Meanwhile, OpenAI relies on Persona to keep bad actors out, protecting one of the world’s most powerful AI platforms from large-scale abuse in a time when AI is reshaping the way we work and live.

About the Role

Persona is looking for motivated iOS and Android Engineers to join our Collection Flow team. Collaborate closely with product, design, and business teams on a small but high-impact team of mobile engineers. Your work will contribute to numerous top 100 apps across the App Store and Google Play Store by delivering high-performance, developer-friendly mobile SDKs that power identity verification at scale. You’ll play a pivotal role on some of the most strategic initiatives for our business and make an impact on the future of online identity. While Persona is headquartered in San Francisco, this team works remotely from locations across the United States and Canada.

What you'll do at Persona

• Leverage native mobile technologies to design, build, and ship best-in-class products. This may include full stack ownership to ensure seamless end-to-end user experience.
• Collaborate with product and design teams across our platform, and sometimes even customers, to define requirements and build solutions.
• Iterate quickly with small, progressive, and adaptive contributions.
• Design and maintain developer-friendly SDKs that prioritize simplicity, clarity, and seamless integration.
• Ensure efficient compilation, dependency management, and minimal binary size for performance-critical applications.

What you'll bring to Persona

• Experience - 2+ years of mobile software engineering experience at a fast-moving technology company.
• Mobile expertise - In depth knowledge of native UI frameworks (UIKit / XML Views), build systems (Xcode / Gradle), concurrent programming models (GCD / Coroutines), native camera frameworks (AVFoundation / CameraX), and native vision frameworks (Vision / MLKit).
• Relentless debugging - You’re driven to uncover the root cause of every issue. End-user and customer reports aren’t just tickets—they’re challenges you’re determined to solve.
• Product mindedness - You build products in a way that maximizes value while minimizing complexity. You can take something ambiguous and turn it into something concrete and built for scale.
• Innovative mindset - You go beyond implementing what is tasked and make product suggestions and features that help push our product forward. You are naturally curious and embrace change.
• Independent thinking - You learn from your mistakes quickly, and know how to unblock yourself when needed. You give yourself agency to take on new problems and drive them to impactful solutions.
• Collaborative spirit - Collaboration isn’t just a buzzword for you, it’s your secret to success. You leverage the diverse perspectives of your teammates and sometimes go out of your way to learn other functions to get the job done.
