Surface emotional-state outputs from the core inference model through clean, intuitive app interfaces.
Build and ship a polished, consumer-grade mobile experience that meets high product standards.
What We're Looking For
At least 2 to 3 years of professional iOS engineering experience; this role is not suitable for fresh graduates.
Strong Swift proficiency and a proven track record shipping polished, consumer-grade iOS applications.
Experience building data-driven apps that present complex model or sensor outputs through clean, accessible interfaces.
Strong computer science fundamentals and the ability to make and own technical decisions autonomously as a founding engineer.
Comfortable working independently across time zones and collaborating on a lean, distributed team.
Full-stack iOS capability, comfortable owning the app layer end-to-end.
