Job Description

You will design and build end-to-end mobile workflows that translate complex real‑world processes into intuitive software.

This high‑ownership role involves moving from customer calls to deployment, solving critical bottlenecks in physical industries.

Location

Why this role is remarkable

• Join a world‑class team featuring former unicorn founding engineers and talent from X, Google, Amazon, and Yandex in a high‑trust, high‑autonomy environment.
• The company is backed by an oversubscribed $4.5M seed round from legendary investors including Coinbase, Reddit, Klarna, and Spotify, providing a strong runway for growth.
• Experience true ownership by embedding with users in industries like aerospace and healthcare to build mobile‑first tools that let physical‑world work move at software speed.

What You Will Do

• Ship production‑grade features from day one, owning the entire lifecycle from initial customer specification and UX polish to final deployment.
• Develop sophisticated offline‑first mobile workflows using React Native and TypeScript, integrating native Swift/Kotlin modules for camera and sensors when necessary.
• Integrate advanced AI‑powered features, including LLMs and agents, directly into mobile workflows to streamline messy real‑world field processes for industrial workers.

The ideal candidate

• Proven experience shipping cross‑platform apps with React Native and TypeScript, with the technical depth to drop into native iOS and Android codebases.
• Strong background in building offline‑first applications that manage local persistence, conflict resolution, and reliable data synchronization in environments with unreliable connectivity.
• Entrepreneurial mindset, ideally with early‑stage or founder experience, and a willingness to work directly with non‑technical domain experts to define product requirements.
