Descripción del trabajo

Remote in Europe | Fluent English required

Join Foundway to shape the future of video analytics in a nascent fast-growing industry.

About Foundway

Foundway 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.

Tasks

The Role

This 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 Do

  • Design & 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 workflow s 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.

Requirements

You’ll Be a Great Fit If You

  • Bring 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.).
  • Get DevOps : Terraform, Docker, CI / CD, monitoring, alerts.
  • Love working smartly and shipping quickly.
  • Thrive in a fast-paced, early-stage environment where priorities shift and nothing is somebody else’s problem.
  • Know how to prioritize high-leverage work.
  • Nice-to-Haves

  • Experience with video pipelines or multi-modal foundational models.
  • Prior leadership or mentoring in small, high-impact teams.
  • Knowledge of available routes for fine-tuning foundational models using Pinecone and similar.
  • Benefits

    Why Foundway

  • Impact opportunity : help define how the world works with video in a nascent, rapidly-growing market at the intersection of AI and media.
  • Compensation : generous equity package with a modest cash stipend until post-fundraising. Competitive salary post-fundraising.
  • Massive ownership : your architecture decisions today will be running years from now.
  • Founding-team timing : become the very first engineering hire and shape the company before we head to YC / Seed, locking in meaningful equity and influence.
  • Flexible work : hybrid Barcelona HQ or fully remote within ±2 hours CET.
  • Lightning-fast process : interview with Founder → deep-dive → offer.
  • Ready to build the backbone of a category-defining product?
