About the company

Our client is a technology company.

The role

Raydar is recruiting for this role on behalf of our client. Own the full-stack product and the AI engineering behind it, taking systems from prototype to production for business users. You will work as a hands-on generalist with a lean toward backend work, partnering closely with the founders and a very small engineering group. The role also covers internal tooling, quality measurement and helping shape the team.

What you'll do

- Build and own backend services, data storage, APIs and an application layer, moving them from prototype to production.

- Integrate multi-step AI reasoning workflows into real customer operating procedures and field processes.

- Co-own evaluation tooling and a feedback loop, designing evaluations with limited data and tracking failure modes to improve model quality each release.

- Build internal tooling and automate company workflows with AI, making build-versus-buy decisions.

- Contribute to go-to-market planning by helping choose which customer segments to pursue next.

- Help recruit and onboard additional engineers as the team grows.


Requirements

What we're looking for

- Early-career engineer, roughly one to three years in, who has put AI-driven or multimodal products in front of real users.

- Ability to own a real-time media pipeline end to end, with depth in low-latency streaming over unreliable networks, media capture, or low-latency model serving.

- A record of early-stage startup work that reached production, or time spent in a demanding, high-ownership engineering culture.

- Backend-leaning full-stack skills, having built databases, APIs and app layers on a modern cloud stack.

- Experience connecting physical devices to software, such as wearables, cameras, robotics, IoT or drones.

- Comfort working close to the hardware in a systems language, including profiling and working within memory and power limits.

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

- Hungry, scrappy and independent, with active use of the latest AI tools.

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

Bonus points

- Computer vision, wearable or AR product experience.

- Edge or on-device inference deployment.

- On-prem or air-gapped deployment in high-security environments.

- Device and firmware fluency, including embedded Linux or device SDKs.

- Founder background or exposure to industrial domains.

- Relevant big-company experience on a directly related team, paired with a builder track record.
