About the role

As an iOS Engineer at Cantina, you’ll lead the development of innovative, high-performance features - from crafting personalized feeds and immersive custom UIs to empowering bots with AI-driven capabilities like chatting, text-to-speech, voice selection, image creation, and real-time media effects.

Working closely with Product Managers, Designers, and Sean Parker, you’ll influence the direction of a product central to the company’s mission, move quickly to deliver impactful updates, and enjoy the autonomy to bring your ideas to life.

• Participate in Architecture meetings to help ensure our apps meet the highest quality standards.
• Collaborate with Product, Design, and QA teams to deliver polished, scalable experiences.
• Take ownership of features - be part of a small team that ships an application to a large user base.
• Be part of an incredibly supportive team that values feedback, both positive and career-growth oriented.

What you'll bring

• 8+ years of experience developing iOS applications, or equivalent education.
• Fluency in Swift, UIKit, and Objective-C, with a strong foundation in custom graphics and animation frameworks.
• Ability to write readable, maintainable, documented, and thoroughly tested code.
• Experience developing integrations with RESTful APIs.
• Proficiency with Git and version control workflows.
• Basic understanding of Figma - able to determine spacing and sizing; bonus if you can export icons and understand variables.
• Experience with video editing, real-time media effects, or AI-driven media features is a plus.
• Ability to effectively translate Product, UX, and UI requirements into code.
• Skilled at evaluating and communicating engineering solutions and trade-offs to teammates and potentially non-technical stakeholders.
• Can create scalable and reusable components that are flexible and modular.
• Attention to detail, motion, and animation.
