About FoundwayFoundway is building the AI OS for video.
Our platform turns hours of footage into instantly-searchable knowledge: ask our agent a question, get the exact clip and a concise answer, plus automatic summaries, metadata, storylines, chapters, transcripts, highlights and repurposed social snippets.Under the hood we blend multimodal foundation models, vector search and a purpose-built video analytics pipeline so teams in media, marketing, learning and product can work with their video, not against it.
We have traction, laser-focused on product-market fit and ready to scale the core system that will power millions of video conversations.TasksThe RoleThis is a high-ownership, high-impact position.
You'll make the core architectural and product decisions that shape Foundway's future, ship production code end-to-end, and lay the engineering foundations for a multimillion-dollar SaaS.
If you thrive on ambiguity, move quickly, and sweat the details of both system design, scalable platforms and multi-modal foundation models, you'll feel right at home.What You'll DoDesign & build a cloud-native backend that scales from dozens to millions of content workflows.Integrate AI services LLM APIs, image models, vector DBs into clean abstractions (no custom model training required, but you'll set the patterns).
Own infrastructure: set up CI/CD, monitoring and observability, and keep latency low and costs sane.Establish engineering culture with fast code reviews, test strategy, release cadence, lightweight docs.Own AI-automation workflows evaluate and adopt AI coding agents and other developer-productivity tools to super-power our small engineering team.Collaborate directly with the Founder & early customers, turning pain points into product iterations and experiments in days, not quarters.
You'll work closely with the Founder on launching experiments that drive product metrics.RequirementsYou'll Be a Great Fit If YouBring 6+ years building production backends and have taken at least one system from 0 to scale.Are fluent in TypeScript/Node and Pythion and comfortable designing REST APIs.Have hands-on experience with relational data modeling plus distributed caches and cloud processes.Have wired up LLM or generative-AI APIs in production products (RAG pipelines, embeddings, prompt orchestration, etc.).
