Job Description:

We’re looking for a Senior iOS Engineer to build the core mobile monetization experiences and iOS foundations that power how users sign up, manage their account, access family features, pay for services, and interact with monetized experiences safely and confidently across OpenAI’s mobile apps. This is a 0→1, greenfield opportunity: you’ll help define the architecture, primitives, and reusable frameworks that product teams depend on to ship quickly while meeting the highest standards for security, reliability, privacy, and user trust.

Job Responsibility:

Build and ship new monetization experiences on iOS, including purchase flows, subscription/plan management, and monetization-adjacent surfaces
Design and maintain shared iOS frameworks and primitives for account, trust, and commerce flows used across OpenAI’s mobile apps
Own complex client-side systems spanning UI, networking, local state, observability, and Apple platform integrations
Optimize performance, reliability, and responsiveness for global-scale usage
Establish and evolve testing frameworks and refine architecture for long-term maintainability
Collaborate deeply with Product, Design, Research, and backend teams
Help uphold the highest levels of safety, privacy, fairness, and policy compliance
Provide technical leadership through architectural reviews, mentoring, and setting engineering standards

Requirements:

4+ years of professional software engineering experience with significant iOS ownership
Proven track record shipping high-quality iOS apps in production for business-critical, reliability-sensitive systems
Fluent in Swift and experienced with Apple’s ecosystem (Xcode, SwiftUI)
Owned complex mobile systems end-to-end (architecture, delivery, instrumentation, quality, and operations)
Care deeply about performance, security, privacy, and user experience, especially in flows involving identity and payments
Thrive in 0→1 environments where systems, architecture, and user experiences must be defined from scratch

What we offer:

Medical, dental, and vision insurance for you and your family, with employer contributions to Health Savings Accounts
Pre-tax accounts for Health FSA, Dependent Care FSA, and commuter expenses
401(k) retirement plan with employer match
Paid parental leave (up to 24 weeks for birth parents and 20 weeks for non-birthing parents), plus paid medical and caregiver leave (up to 8 weeks)
Paid time off: flexible PTO for exempt employees and up to 15 days annually for non-exempt employees
13+ paid company holidays, and multiple paid coordinated company office closures
Mental health and wellness support
Employer-paid basic life and disability coverage
Annual learning and development stipend
Daily meals in our offices, and meal delivery credits as eligible
Relocation support for eligible employees
Additional taxable fringe benefits, such as charitable donation matching and wellness stipends
Offers Equity
Performance-related bonus(es) for eligible employees
