The role

Raydar is recruiting for this role on behalf of our client. Own the product layer of a hardware-connected software platform, spanning backend services, live media delivery and user-facing applications. The role involves setting early technical direction and delivering complete features that customers can operate without engineering support.

What you'll do

- Deliver the complete user experience across a wearable device, backend services and a companion application.

- Build and tune a live media streaming pipeline that stays within strict latency limits.

- Own backend APIs and the data layer, keeping them dependable, observable and ready to scale.

- Create client applications that let users configure, oversee and get started with the product.

- Set up the deployment and release process so new builds reach devices in the field safely.

- Shape product architecture and engineering practices as the team grows.

- Act as a cross-stack generalist, tracing issues from the user interface through the backend to the device.


Requirements

What we're looking for

- 2 to 5 years of experience launching new products with real users, from first build onward.

- End-to-end ownership of full applications, covering backend, APIs, data layer and the client users interact with.

- Early-stage startup or founding engineer experience, or background in a similarly high-intensity engineering culture.

- Hands-on work with live audio or video delivery and other time-sensitive data paths.

- Experience integrating AI or LLM-based features into a product.

- Strong computer science or engineering foundation, or an equivalent record of shipping.

- Full-stack ability on a modern cloud stack, including TypeScript and PostgreSQL.

- Ability to make sound, scalable architectural decisions independently.

- Willingness to work on-site five days per week.

Bonus points

- Background with media-intensive platforms or performance-sensitive systems.

- Exposure to industrial settings.

- Interest in frontend, design or UX craft.

- A history of releasing apps to consumer app stores, native or cross-platform.

- Relevant big-company experience on a closely related team, combined with a builder mindset such as founding or side projects.
