Founding Senior Backend Engineer
Foundway
- Barcelona
- Permanente
- Tiempo completo
- 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 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.
- 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.
- 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.
- 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.
