About the Role
We are looking for a Senior Software Engineer – iOS to join a growing product team and help build polished, reliable mobile experiences for creators and consumers. This role combines hands-on iOS development with production ownership, technical problem-solving, and mentorship. You’ll work across the full development lifecycle—from technical design and implementation to testing, release, monitoring, and continuous improvement.
You’ll have the opportunity to make meaningful contributions to the product while helping establish strong engineering practices that support scalability, performance, and long-term maintainability.
Mission
Build polished, reliable iOS experiences that help users connect, create, and engage while continuously improving application architecture, performance, and development practices.
Success in this role will include:
- Delivering roadmap features that meet agreed requirements and acceptance criteria.
- Improving crash-free usage and key application performance metrics.
- Strengthening automated test coverage across critical iOS user journeys.
- Reducing recurring defects and improving release predictability.
- Contributing to scalable, maintainable mobile architecture.
- Helping establish engineering standards and best practices across the mobile development team.
Core Responsibilities
- Own iOS features from technical design through implementation, testing, release, and production monitoring.
- Build accessible, responsive, and reliable mobile interfaces using modern iOS development practices.
- Develop and maintain integrations with APIs, authentication systems, local data storage, and background processes.
- Diagnose and resolve crashes, concurrency issues, memory problems, and performance bottlenecks.
- Contribute to application architecture and improve development tools and processes.
- Write clean, maintainable, well-tested code.
- Participate in code reviews and provide constructive technical feedback.
- Mentor other engineers and contribute to a collaborative engineering culture.
- Participate in a defined production-support or on-call rotation.
- Collaborate closely with backend, Android, QA, Product, and Design teams.
Requirements & Competencies
- 5+ years of professional software engineering experience, with substantial experience building and shipping native iOS applications.
- Strong experience with Swift and SwiftUI and/or UIKit.
- Strong understanding of the iOS application lifecycle, concurrency, networking, and API integration.
- Experience writing and maintaining automated tests for mobile applications.
- Experience diagnosing and resolving production issues, including crashes, memory problems, and performance bottlenecks.
- Understanding of mobile security, accessibility, application signing, CI/CD, and App Store release processes.
- Ability to independently design, develop, debug, test, and maintain production-quality software.
- Strong communication and collaboration skills.
AI-Assisted Development
- Experience developing software both with and without agentic or generative AI coding tools.
- Ability to use coding assistants and AI agents effectively to accelerate development while maintaining engineering quality.
- Ability to independently evaluate, debug, and validate AI-generated code.
- Strong accountability for the correctness, security, performance, and maintainability of all production code.
- Understanding of how to protect proprietary code, credentials, and sensitive information when using AI development tools.
Nice to Have
- Experience building social, creator, community, or media-focused applications.
- Experience working with media-heavy mobile applications.
- Experience with real-time features, feeds, messaging, or content publishing.
- Experience with performance optimization and mobile observability.
- Experience working in a fast-paced product environment with frequent releases.
- Experience mentoring engineers or contributing to mobile engineering standards.
First 90 Days
Days 1–30:
- Learn the existing iOS architecture, development practices, product roadmap, and release process. Identify key stability, performance, and technical risks.
Days 31–60:
- Ship a tested feature or priority production improvement while establishing effective monitoring and validation practices.
Days 61–90:
- Improve a key reliability or development bottleneck and collaborate with the team on a prioritized technical improvement plan.
Collaboration & Reporting
- You’ll report to the Mobile Engineering Manager or Head of Engineering and work closely with Android, Backend, QA, Product, and Design teams.
- This is a senior individual contributor role with opportunities to influence technical decisions, mentor engineers, and contribute to the evolution of the mobile engineering organization.
Why Join?
Join a growing product team where your work will directly shape the mobile experience. You’ll have the opportunity to own meaningful iOS features, solve challenging technical problems, mentor other engineers, and help establish the engineering standards needed to support the product’s next stage of growth.
