Senior iOS Engineer

About the Role

We’re looking for a Senior iOS Engineer to help build and scale the Slips iOS app — a core surface of our peer-to-peer platform. You’ll play a critical role in shaping product experiences used daily by real users, handling real money, and operating at real scale.

This is a hands‑on role for a builder who cares deeply about performance, UX polish, and clean architecture, and who wants meaningful ownership in a fast‑moving environment.

• Design, build, and maintain core features of the Slips iOS app
• Own end‑to‑end implementation of new product experiences, from concept to release
• Collaborate closely with product, design, backend, and data teams
• Optimize app performance, reliability, and responsiveness
• Help define and evolve our iOS architecture, tooling, and best practices
• Review code, mentor engineers, and raise the overall quality bar
• Ship frequently and iterate based on real user feedback

• 5+ years of professional iOS development experience
• Strong proficiency in Swift and modern iOS frameworks
• Experience building and scaling production iOS apps
• Deep understanding of iOS architecture patterns (MVVM, modularization, etc.)
• Strong grasp of performance optimization, memory management, and debugging
• Experience working with APIs, real-time data, and asynchronous systems
• High attention to detail in UI/UX and animation polish
• Comfortable owning large features and making technical decisions

• Experience with fintech, payments, gaming, or real-money products
• Familiarity with App Store release processes and Apple guidelines
• Experience working in fast‑paced startup environments
• Exposure to analytics, experimentation, or growth tooling
• Interest in peer‑to‑peer systems, marketplaces, or social products

• Build a next‑generation peer‑to‑peer platform — no house, no middleman
• High ownership and real influence on product direction
• Small, talented team with fast decision‑making
• Opportunity to ship meaningful work that users see immediately
• Competitive compensation and meaningful upside

We value builders who take ownership, move fast, and care about the details. Titles don’t matter as much as impact. The best ideas win, and shipping beats perfection.

Access a range of benefits, resources, and expert guidance to help you prioritize your well‑being, so you can thrive with a healthy body and mind.

No matter where you’re working from, we want to ensure you’re set up for success. We provide tools and generous financial support to complete an ideal workspace.

Slips encourages employees to step away from work to relax, recharge, and spend time solo or with family and friends! In addition, unpaid or bereavement leave.

Becoming a parent is a huge milestone. Slips strives to offer caregivers time to spend with their children and family – providing paid leave.

We understand that life happens outside of work. That’s why we offer flexibility for you to do your best work in a way that works for you.

We’re always looking for great talent! If a referral is hired full‑time, the referring Slips will receive a bonus once the new starter has been with us for 3 months.

We value passionate, self‑motivated individuals who want to make a difference.
