The Role
About EarnIn

As one of the first pioneers of earned wage access, our passion at EarnIn is building products that deliver real-time financial flexibility for those with the unique needs of living paycheck to paycheck. Our community members access their earnings as they earn them, with options to spend, save, and grow their money without mandatory fees, interest rates, or credit checks.

We’re fortunate to have an incredibly experienced leadership team, combined with world-class funding partners like A16Z, Matrix Partners, DST, Ribbit Capital, and a very healthy core business with a tremendous runway. We’re growing fast and are excited to continue bringing world-class talent onboard to help shape the next chapter of our growth journey.

POSITION SUMMARY
We’re looking for an iOS Engineer to join our Core UX Team, building high-quality mobile experiences that directly impact EarnIn’s customers. This role is ideal for an individual with a solid foundation in iOS development, a keen eye for user experience, and a desire to collaborate across mobile and product teams. While the primary focus is on iOS, we value engineers who are open to broadening their impact by learning from Android and backend peers to deliver features end-to-end.

You’ll work closely with designers, Android engineers, and backend partners to deliver and maintain intuitive, scalable features. You’ll have opportunities for technical ownership, cross-platform collaboration, and ongoing growth. We believe in strong team communication, a culture of shared learning, and supporting each other to achieve excellent results.
 
This position will ideally be hybrid from our Mexico City office as part of our expanding site, though a remote arrangement is possible. EarnIn offers excellent employee benefits, including healthcare, internet and cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our headquarters in Mountain View. Our salary ranges are determined by role, level, and location.
 
WHAT YOU’LL DO
  • Develop and evolve mobile features that support key customer-facing experiences and core workflows.
  • Collaborate with product and design partners to turn UX ideas into polished, reliable mobile experiences.
  • Write clean, maintainable, and well-tested Swift code using modern frameworks.
  • Participate in sprint planning, code reviews, and cross-platform discussions with iOS, Android, and backend teams.
  • Collaborate with Android and backend engineers to ensure seamless cross-platform cohesion and effective backend integration.
  • Investigate and resolve production issues, with a focus on minimizing end-user impact and driving continuous improvement.
  • Support initiatives focused on performance tuning, accessibility, and instrumentation to enhance UX visibility.
  • Work closely with QA and product to validate features and ensure high-quality releases.
  • Proactively engage in team learning, knowledge sharing, and embracing new tools and technologies.
WHAT WE’RE LOOKING FOR
  • Bachelor’s degree in Computer Science or related field, or equivalent practical experience.
  • Proficiency in Swift and modern iOS development practices, including architectural patterns such as MVVM.
  • Experience with development and debugging tools like Xcode, Instruments, Crashlytics, and Git.
  • Strong collaboration skills and the ability to contribute to user-focused, cross-functional solutions.
  • Solid understanding of UX principles, mobile interaction patterns, and design system alignment.
  • Good testing practices, including unit and UI testing to support code quality and stability.
  • Clear communication and collaboration skills in distributed team environments.
  • 3+ years of experience building and shipping iOS applications in production environments.
  • Experience working in fast-paced, iterative teams using Agile or similar methodologies.
  • Experience with accessibility standards, mobile analytics, or performance optimization.
  • Proactive interest in working with AI tools and on AI-driven solutions: You’ll have opportunities to use generative AI, automation, and AI-powered analytics to enhance our product and your workflow, driving innovation at EarnIn.

What We Do

Earnin’s mission is to build a financial system that works for people. Every year, while Americans wait for their paychecks, more than $1 trillion of their hard-earned money is held up in the pay cycle. As a result, we accumulate over $50 billion in late and overdraft fees and turn to high-interest loans. We seek to eliminate those fees and put money back into workers’ hands.

Our financial system doesn’t work for people. But Earnin does. Earnin is an app that lets people get paid as soon as they leave work, with no fees, interest, or hidden costs. App users can receive their money in their bank account instantly at little or no cost — as we operate on a pay what you choose model. All they need is a bank account and a job that provides direct deposit or uses electronic timesheets.

At Earnin, we’re building the way we think a financial system should work for everyone, not just the people who can afford it. We help people take control of their money and get to a better financial place.

Our goal is not only to provide great products at little or no cost to the people who need them but also to inspire kindness across the financial world and eventually across all industries.
