About the Role

  • We’re looking for an iOS Engineer with serious chops — someone who builds smooth, reliable, and high-performing apps. You’ll work on complex mobile experiences that power crypto access for thousands of users across Africa (and beyond). Whether you’re a senior engineer ready to deepen your impact or a staff engineer ready to lead architectural decisions and mentor the next generation, this role was made for you.

What You’ll Be Owning

Drive Mobile Engineering Excellence

  • In your first 90 days: Own and optimize our iOS app’s architecture—make it scalable, fast, and future-proof.
  • By 6 months: Lead cross-functional delivery with product and design, shipping major features that delight users.
  • On-going: Define and enforce iOS best practices, from code quality to performance optimization.

Technical Leadership

  • Be a thought leader on the team and across the organization
  • Lead technical decisions around native iOS contributions
  • Mentor and coach junior and mid-level engineers to elevate the team’s output and culture.
  • Architect and develop mobile strategy in alignment with Quidax’s growth and crypto roadmap.

Team & Culture Building

  • Collaborate closely with product, design, and other stakeholders to ship great products
  • Provide technical structure to teams and collaborate with management and stakeholders to define and implement strategic roadmaps

Biggest Challenges You’ll Tackle

  • Here’s what will keep you up at night, but you will want to get it solved like yesterday
  • Balancing rapid feature delivery with bulletproof app performance and stability, no pressure.
  • Navigating complex integrations between native and web content without losing your mind.
  • Driving technical strategy and implementation for iOS, including architecture, performance, and security
  • Raising the technical bar while mentoring others and keeping delivery fast
  • Balancing product velocity with long-term architectural decisions
  • Helping define what great looks like for crypto experiences on Mobile

What We’re Looking For

  • You write clean code. You sweat the small stuff when it matters. You obsess over system design. And you care about impact.
  • 8+ years of hands-on experience in iOS development with proven experience leading projects or teams
  • Experience architecting and developing solutions to ambiguous problems with significant impact
  • Strong command of Swift, SwiftUI, and mobile architecture principles
  • Proficiency in Kotlin Multiplatform and Dart for cross-platform projects
  • Familiarity with Combine, MVVM, and performance optimization techniques

  • You’ve built secure, highly reliable financial systems (bonus point if in crypto space)
