Product Engineer (AI-Driven / Mobile Apps)

Full Description

Product Engineer (AI-Driven / Mobile Apps)

Picup Media is the world’s leading digital transformation platform for the jewelry industry — and the creator of the world’s first smartphone jewelry lightbox.

Founded in Sydney in 2014, we have served 20,000+ jewelers globally.

We are building a fully digitized jewelry ecosystem that tightly integrates mobile apps, hardware devices, cloud platforms, and AI services — enabling jewelers to capture, manage, verify, and sell products seamlessly across channels.

We are expanding our Hong Kong team to hire a Product Engineer — a hands‑on product builder who combines mobile engineering execution with strong product intuition, empowered by AI tools such as Cursor 2.0 and GPT‑5 Codex.

What You’ll Do

Own end-to-end mobile product modules — from concept to App Store / Play Store release — across key workflows such as product capture, media management, verification (GemUV), and AI‑assisted features.

Design and implement mobile‑first user experiences for jewelers, balancing usability, performance, and real‑world constraints (lighting, camera, workflow speed).

Use AI‑assisted development tools (e.g.

Cursor, Copilot, GPT‑5 Codex) to prototype UI flows, generate mobile components, and accelerate feature delivery.

Collaborate closely with design, backend, and hardware teams to translate product requirements into mobile‑ready APIs, data models, and interaction flows.

Integrate mobile apps with hardware devices and sensors (e.g. camera systems, lighting controls, Bluetooth / USB accessories) where applicable.

Partner with AI engineers to bring AI‑powered features into mobile experiences, such as:

• Image enhancement and generation (GemStudio)

• Jewelry appraisal and identification (GemID)

• Diamond detection and fluorescence workflows (GemUV)

Conduct lightweight user testing, instrumentation, and data‑driven iteration to continuously improve conversion, retention, and workflow efficiency.

Contribute to mobile product roadmaps and establish AI‑augmented development best practices across Picup Media’s global teams (Hong Kong, Shenzhen, Sydney).

Who You Are

Bachelor’s degree or above in Computer Science, Software Engineering, or related field.

4–8+ years of experience in mobile app development, product engineering, or technical product roles.

Strong hands‑on experience with mobile frameworks, such as:

• React Native

• Flutter

• Swift (iOS)

• Kotlin (Android)

Comfortable reading, debugging, and modifying production mobile codebases.

Experience working with camera APIs, media pipelines, or performance‑sensitive mobile features is a strong plus.

Familiar with API‑driven architectures and collaborating with backend teams.

Comfortable using AI tools for development (Cursor, Copilot, ChatGPT, Claude, etc.) and iterating via prompt‑driven workflows.

Strong product thinking — you can connect user intent, UI behavior, data structure, and system constraints holistically.

Excellent communication skills in cross‑functional, multicultural teams.

English fluency required; Cantonese and/or Mandarin a plus.

Why Join Us

Competitive salary and performance bonus.

Direct collaboration with founders, AI engineers, and hardware teams in Hong Kong and Shenzhen.

Build real mobile products used daily by 20,000+ jewelers worldwide.

Work at the intersection of mobile, hardware, and AI, using cutting‑edge tools like Cursor and GPT‑5 Codex.

Flat structure, fast iteration, and genuine ownership from concept to shipping.
