Have you ever wanted to build something that fundamentally changes how humans understand themselves? At Clera, a Y Combinator backed consumer wearable startup, we are bridging the gap between biometrics, emotional intelligence, and cutting edge mobile software. We are developing a wearable device that reads emotional states in real time, serving as a fitness tracker for your EQ by processing over 150 audio and biometric signals. Prototypes are already actively on users wrists, meaning you will join a live product with genuine momentum. As our Founding Full Stack iOS Engineer, you will take absolute ownership of our companion app and help shape the future of emotional technology from day one.

Overview

This is a fully remote, worldwide opportunity giving you the chance to work alongside world class founders in hardware, neuroscience, and design. Because you are coming in at the ground floor, you will own our iOS architecture completely and naturally step into a leadership role as the company scales. We need someone who loves crafting buttery smooth consumer experiences and cares deeply about making complex biometric data feel intuitive and human.

Key Responsibilities

Own the companion iOS app end to end, making foundational architecture decisions and delivering pixel perfect user interfaces.
Translate complex backend inference outputs, such as energy, mood, and focus scores, into compelling and polished consumer experiences.
Partner directly with our hardware and neuroscience teams to ensure seamless Bluetooth communication and real time data syncing.
Iterate rapidly based on direct user feedback from our active cohort of early testers.

Requirements

Proven track record of building, shipping, and maintaining polished consumer iOS applications available in the App Store.
Deep expertise in Swift, SwiftUI, Combine, and modern iOS frameworks.
Strong grasp of mobile architecture patterns, offline first data persistence, and low latency Bluetooth LE integration with hardware devices.
An obsessive eye for design detail, fluid animations, and delightful user interactions.
A high agency mindset with the ability to thrive in an ambiguous, fast paced startup environment without a playbook.

What You Will Gain

A true founding team experience with significant equity and a direct voice in product direction.
The freedom to work from anywhere in the world with a flexible, results oriented remote culture.
The chance to scale into a formal engineering leadership role as our team and user base grow.
Direct exposure to cutting edge computational neuroscience and hardware engineering.
