Senior iOS Engineer

Overview

Senior mobile engineer with an iOS focus to lead mobile experimentation and growth for Tilt's flagship Cash Advance product, which helps users cover the gap between paychecks.

What you'll do

• Own the mobile experience for Cash Advance from sign-up to first advance to repeat use, including optimizing onboarding, conversion and repeat usage.
• Run experiments that test different product constructs and UX approaches, working from hypothesis to launch and validating what works before scaling it.
• Drive an assigned outcome, such as 40% conversion, by finding the right levers with design and product rather than waiting for a detailed spec.
• Hold the line on precision in a regulated financial product, recognizing that errors can trigger fee refunds, regulatory exposure and lost user trust.
• Collaborate with PMs, designers, data science and backend engineers to build financial experiences that hold up technically, experientially and from a regulatory standpoint.
• Build and ship features end to end on iOS and Android, keeping the Cash Advance experience consistent for every user.

What you'll need

• 5+ years of experience as an iOS engineer building consumer-facing iOS products.
• A consumer product background, having built products that real users interact with daily.
• Product experimentation and analytics experience, including A/B testing frameworks such as Statsig or LaunchDarkly, or analytics platforms such as Amplitude or FullStory.
• Outcome-oriented approach: able to drive an improvement independently by thinking through the user journey, partnering with design, and designing experiments and iterating.
• Attention to detail beyond code quality, building with awareness of downstream consequences in a regulated product.
• Comfortable working cross-platform and working in Android code as a regular part of the job.

Nice to have

• Hands-on experience shipping on both iOS and Android.

Details
