About the Role

Join an early-stage AI video team as a founding backend engineer, helping build the systems behind generative video products. You will provide technical leadership on a small team and establish strong engineering practices as the product and infrastructure grow.

What You'll Do

Design and develop scalable backend systems for AI-powered video creation.

Build infrastructure for agentic workflows, video generation pipelines, reinforcement learning loops, and real-time data processing.

Own distributed systems architecture and improve reliability through automated testing, performance benchmarks, and end-to-end observability.

Partner with research, engineering, and design teammates to develop product features and APIs.

Write production code, set technical direction and engineering guidelines, and raise the team's engineering standards.

Document systems and technical decisions clearly in a fast-moving, on-site environment.

What We're Looking For

Five to ten years of backend software engineering experience, including experience at an early-stage or high-growth startup.

Professional experience building scalable backend and distributed systems, including large-scale data processing, information retrieval, or asynchronous workflows.

At least one year of industry experience designing and building agentic systems, LLMs, or generative AI products.

Industry experience with TypeScript and AWS; familiarity with S3, Lambda, RDS, SQS, ECS, FastAPI, Docker, and CI/CD is relevant.

Strong fundamentals in algorithms, data structures, and system design, applied in professional backend work.

Experience serving as a technical lead, setting direction and code standards while remaining hands-on.

A formal degree, fluent English, and work authorization that does not require visa sponsorship.
