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.

What you need to know about the Los Angeles Tech Scene

Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.

Key Facts About Los Angeles Tech

  • Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
  • Key Industries: Artificial intelligence, adtech, media, software, game development
  • Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
  • Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
