Lead iOS Engineer

Just three years in, 25% of young women in the US (18-25) have downloaded Co–Star. Our growth has been entirely through word of mouth—we’ve never spent money on ads. We have millions of active users, raised $21,000,000 from the people behind companies like Twitter, Discord, and Snap, and just launched our second paid feature.  For thousands of years, astrology has given people the tools to reflect and connect in real, meaningful ways. Co–Star brings astrology into the 21st century with an app that users call their “best friend” and that therapists recommend to their clients. Astrology is a deterministic system based on the time it takes a planet to orbit the sun. It's more like folk developmental psychology than it is like fortune cookies. Using NASA data interpreted by humans, Co–Star delivers personalized readings in real time. Our AI strings human-written snippets together to generate hyper-personalized interpretations of planetary movements for millions of people.We're looking for a Lead iOS Engineer to lead architectural decisions within the iOS app and build and shape key features that merge astrology and technology. You’ll help tens of millions of people connect to each other and themselves – through astrology – in real, meaningful ways.

What you’ll do Lead architectural decisions within the iOS app  Architect and build smooth, stable, and fun features for the Co–Star iOS app using Swift Work closely with product/design to identify opportunities, evaluate tradeoffs, and translate product goals into high quality shippable code Spec, build, test, and deploy user experiences through an agile, collaborative process from design through implementation and launch Work closely with a small, cross-functional team to ship new features, including backend (we use Haskell), product, design, and data science Be the go-to person for guidance when it comes to product decisions, so you'll have a direct impact in keeping the business productive

What you'll bring Experience directing sprint planning and code reviews for iOS teams Hands-on experience writing well-documented, easily-tested code in Swift using modern architecture paradigms A deep appreciation for our intentionally-not-like-other-startups aesthetic ;)  A passion for statically verifying code A disciplined approach to development, testing, documentation, and code structure in a team environment  8+ years of experience and strong CS fundamentals

Our stack Python wrapper intakes NASA data about where the planets are to find the patterns in the night sky from the perspective of earth  Haskell backend transforms data, gives writers superpowers, and delivers resonant, personalized content BigQuery stores TB of data to create insight for internal teams Native Swift & Android apps create an incredible mobile experience that feels made-for-your-fingers  AWS infrastructure scales to serve millions of people What an NLP professor called a “virtuoustic” use of Google Sheets We’ve been taking a full-stack approach to the way we work so far, but want people to own and lead the domains they feel passionate about – whatever they may be   How we work  We've been working remotely since the pandemic, so we welcome remote candidates for this role. In no way does remote mean isolated. We’re big into cross-functional collaboration. We ideate collectively, ship qualitatively-validated MVPs, and iterate based on internal & customer feedback. We validate what we think people need with iterative user testing, A/B test everything, and use data to inform our decisions. Weekly, the whole team talks through why tests worked or failed and plans our sprints. Quarterly, the entire company comes together to think of what we want to build. Every single member of the team has deep knowledge of and experience in something relevant to building Co–Star, be it astrology, community, or world-building.  What we offer
