At Spruce, our mission is to let users control their data across the web. Instead of people signing into platforms, platforms should sign into people's data vaults, such as digital wallets that hold credentials.

There are no well-worn paths or theoreticals here. Every Spruce technical staffer gets their hands dirty writing code, learning new technologies, and solving problems at the bleeding edge of our space. We hire results-oriented developers who love technology and are committed to intellectual honesty, user privacy, and innovation.

The ideal candidate for this mobile engineering role will have experience developing Android and iOS apps through their full lifecycle, from concept through shipping to maintenance. You will work on a privacy-first digital identity wallet, controlled by the end user. We use a combination of core libraries that we also maintain, low level protocols, and new interoperable digital credential standards. Most important, you interested in challenging opportunities for significant personal growth.

We are a fully distributed team, but our working hours run from PT (UTC-8) through CET (UTC+1).

• Build, maintain, and extend credential wallet applications on Android and iOS.
• Integrate open source libraries for issuing and displaying digital credentials.
• Develop secure software that handles sensitive user data.
• Work closely with customer delivery leads, engineers, product managers, and UX designers

• 2+ years experience shipping Android and iOS applications
• Experience with Kotlin or Swift.
• Experience with Flutter or React Native
• Experience collaborating with geographically and culturally diverse engineering teams

• Experience working on public sector or enterprise software
• Experience with low level communications protocols, especially Bluetooth Low Energy, NFC, and WiFi Aware
• Understanding of computer security, basic use of cryptography, and principles of user data privacy
• Experience with secure enclaves, hardware-based cryptography, or sensitive data handling on Android and iOS
• Experience building backend APIs
• Bachelor's Degree in computer science, engineering, or related field.

We are passionate about cultivating a thriving culture of diverse individuals who bring unique perspectives to our mission. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.
