Founding Engineer
Ultralytics LLC
Ultralytics is hiring three founding engineers to form a second product team based in its new New York office. These roles function as tech leads who bring high ownership, production software experience, and a strong interest in AI experimentation to build and scale the company’s SaaS platform and related products. Key responsibilities: Lead technical decisions and architecture choices for platform features as a tech lead. Own significant product components end to end, from initial build through production deployment, billing, and compliance. Build and maintain scalable cloud infrastructure and microservices that support real user sign-in and enterprise requirements. Experiment with and integrate new AI models and tools into production systems. Anticipate and address scalability, reliability, maintenance, and regulatory concerns before they become problems. Collaborate closely with product leadership on day-to-day technical direction in a distributed team. Must haves: Tech-lead background leading technical direction for a cross-functional team (manager title not required). Strong love of AI demonstrated by personal experimentation outside work End-to-end ownership of a significant product component shipped to production in a smaller or mid-sized company environment, including backend, databases, and compliance considerations. Experience receiving and responding to critical feedback inside a mature organization with structured reviews and demanding clients. Software engineering focus with cloud infrastructure experience on GCP or AWS. Nice to haves: GPU or high-performance machine at home for running models. Experience deploying products on-premise or in air-gapped environments. Computer vision background. Prior engineering management experience. Tech-lead work specifically on AI products. About the product: Ultralytics builds a SaaS platform and open-source tools (including YOLO models) that enable developers and companies to use computer vision and AI. The platform serves both mass-market users and enterprise clients who require air-gapped, on-premise deployments with strict compliance and support needs. Why join: This is an opportunity to help shape a new product team from the ground up in the recently opened New York office, working directly with the management team. The search explicitly seeks engineers who want greater ownership and the ability to influence architecture and product direction in ways the prior team did not.
