You'll co-own development and enhancement of our iOS Software Development Kit, help shape the future of all of our video APIs, and lay groundwork to ensure that calls on mobile are always high quality and reliable.

Who we are

Daily is WebRTC video and audio for every developer. We're building the APIs and infrastructure to power the future of video, and the Internet.

Developers use Daily to add real-time video and audio experiences to any product. Our features range from prebuilt UIs and lower-level APIs to call quality data and global infrastructure and compliance. We serve developers across use cases — like events, productivity, edtech, and healthcare — and serve teams of all sizes. We're a remote team led by seasoned executives who value inclusivity and work-life balance, focus on growth (last year we saw 10x growth), and have raised over $60 million in funding to date.

The role

We take pride in making it as easy, fast and flexible as possible for developers to build with video. We are building our first generation of native mobile Software Development Kits (SDKs) for video, and are in need of a talented and experienced iOS developer to join our client SDK team and help us further develop an intuitive, reliable, and delightful iOS SDK.

Building a library for developers is a pretty different task from building an application for consumers, so we are searching for iOS developers with some unusual skills.

The least unusual part for this role is comfort with the iOS ecosystem. We make extensive use of Swift and, where necessary, limited use of Objective-C++ and Objective-C—and our SDK should feel native and natural to everyday iOS app developers. So it should be written by people well versed in iOS’s style and idioms.

Here are some of the unusual parts of this role:

• Our system needs deep communication between Apple’s platform APIs and low level libraries. Our native SDK core library is written in Rust, so we pass loads of data from Rust to C, then C to Swift (or Objective-C), and then all the way back! (Here’s a talk one of engineers gave about how we do all this and here’s a post on how and why we use Rust, though some of the benefits are limited with C/C++.) Understanding of memory models, ownership and lifetime models, cross-compilation, and related concepts is very important to writing solid software here.
• We make heavy use of iOS's audio and video APIs (Swift), Google's WebRTC project (ObjC/ObjC++/C++), and Mediasoup (C++). Those each involve deep concepts and tooling. Everyday conversations range from OS graphics frameworks to stream multiplexing to API design.
• This work requires both independence and strong collaboration skills. You'll be one of two iOS engineers making big decisions for iOS and being the experts, but you’ll also collaborate with other SDK owners who have conflicting opinions and needs. It's important to communicate early, often, and charitably, but also to work comfortably with little to no guidance.

We will also eventually begin exploring and supporting other SDK environments (e.g. Flutter), and will likely grow the team. We need help writing a great API, and we also need help building a good documentation base and test infrastructure. All while keeping a positive and curious environment on our team.

What you'll do

• Build new video call features in Swift on top of our initial iOS library
• Establish new communication pathways between low level WebRTC libraries and our clients' applications.
• Shape the future of Daily's call APIs
