About Sesame

Sesame believes in a future where computers are lifelike - with the ability to see, hear, and collaborate with us in ways that feel natural and human. With this vision, we're designing a new kind of computer, focused on making voice agents part of our daily lives. Our team brings together founders from Oculus and Ubiquity6, alongside proven leaders from Meta, Google, and Apple, with deep expertise spanning hardware and software.

Responsibilities:

• Build Sesame’s standalone companion app — the foundation for a new consumer product category — on a team that highly values craft and quality.
• Work with multiple teams across engineering, design, and product to ship complex projects that delight users.

• Always up to date on the latest iOS UI/UX design patterns; tuned into the Apple release cycle and always thinking about how the latest features can help the team produce an even more incredible experience.
• Lots of hands-on experience with the software development lifecycle of iOS apps: build trains, test strategy, and the latest UI architecture patterns.

Preferred Qualifications:

• Experience building complex or advanced ui that required you to step off the golden path of the SDK.
• Experience with real-time communications, including WebRTC, Websockets, audio/video codecs, compression protocols, etc.

• Experience integrating BLE peripherals on iOS.
