Job Type
Full-time
Description
As our Lead Software Engineer, you will own the architectural vision and technical strategy for the entire Stax mobile ecosystem. This is a hands-on role for a leader passionate about user experience and cutting-edge technology. You will not only develop our core apps, SDKs, and device integrations, but also mentor a talented team, empowering them to build solutions that are critical to our business goals.
Key Responsibilities & Objectives
Architect, develop, and maintain Stax's core mobile product offerings, including the 'Stax Pay' apps (iOS/Android), public-facing payment SDKs (Kotlin/Swift), and payment terminal integrations. Act as the key technical partner for product teams to architect and deliver new features across our mobile, card reader, and terminal platforms. Drive integrations with Android-based hardware devices and ensure seamless performance across environments. Enhance and support mobile-centric technologies including tokenization scripts, backend services, and terminal customizations. Define and champion the coding standards, architectural patterns, and best practices that ensure quality and consistency across all mobile development. Mentor and guide engineers across teams on mobile platform technologies and SDK usage. Maintain and continuously improve developer documentation for SDKs and integrations. Translate business requirements into technical specifications, collaborating with product managers and external partners to define roadmaps and ensure alignment. Own the end-to-end mobile app distribution process, from publishing and updates to managing all interactions with the Apple App Store and Google Play Store review teams. Requirements
Bachelor's degree in Computer Science or equivalent practical experience. 7+ years of professional mobile development, with deep expertise in Android (Kotlin) or iOS (Swift) and strong proficiency in the other. 3+ years of experience working on a mobile product that served at least tens of thousands of weekly active users. A minimum of 2 years in a technical leadership role (e.g., Project Lead, Senior Engineer with mentorship duties) overseeing complex, multi-layered mobile projects. Experience leading or mentoring teams in SDK and mobile platform development. Track record of managing widely distributed SDKs with versioning, backward compatibility, and developer adoption in mind. Familiarity with mobile app distribution processes and review team interactions for both Apple App Store and Google Play Store. Experience managing platform-specific capabilities that cross-platform frameworks cannot fully support, such as Bluetooth permissions, networking, background services, push notifications, and secure storage. Strong expertise with at least one mobile package manager (e.g., Cocoapods for iOS or Maven Central/Gradle for Android) to support SDK commercialization and distribution. Proven ability to foster a collaborative and supportive team environment through empathetic leadership, mentorship, and constructive feedback, as demonstrated by professional references from former colleagues. Strong problem-solving skills and demonstrated ability to work across diverse technologies. Preferred Qualifications
Experience integrating with Android-based payment terminals (e.g., Dejavoo, Verifone). Background in FinTech or payments technology. Familiarity with Cocoapods, CI/CD pipelines (Gradle, Fastlane), and Firebase (e.g., push notifications). Familiarity with mobile testing frameworks and developer experience tooling. 2+ years of experience with frontend or backend JavaScript/TypeScript applications. Why You'll Love Working at Stax
