Jobs in Spain

At Maite.ai, we're building AI agents that transform how legal professionals work. We don't just want to make lawyers 10% faster - we want to reimagine legal practice entirely. Our mission is simple but ambitious: fight for a fairer world through technology. We're a team obsessed with our users, radical about truth, infinitely curious, and living in the future.

We're looking for an AI Platform Engineer who will architect and maintain the infrastructure that powers our AI-driven legal platform. This isn't a role where you'll manage existing systems - you'll be building the foundation that takes our AI research from experiments to production-grade tools used by thousands of legal professionals daily.

You'll be joining at a pivotal moment: we're scaling from proof-of-concept to enterprise-grade reliability. Your work will directly impact whether lawyers can trust our AI to handle their most critical cases.

How do you build infrastructure that's reliable enough for legal work (where accuracy matters), fast enough for real-time document analysis, and flexible enough to integrate the latest AI breakthroughs?

• Design and evolve our AI infrastructure across Google Cloud, AWS, and specialized services (Qdrant, Supabase, Sentry) to support multiple LLM providers (OpenAI, Anthropic, Gemini) and vector search at scale
• Build and improve AI document processing pipelines including OCR systems, text extraction from complex legal documents (.docx, PDFs), anonymization, and embedding generation for semantic search
• Implement robust monitoring and observability for AI systems in production - track model performance, latency, costs, and reliability. Make our AI transparent and debuggable
• Create CI / CD pipelines that automate model deployment, testing, and rollback strategies. Enable the team to ship confidently and frequently
• Strengthen security and governance: Implement best practices for data protection, access control, and compliance (critical in legal tech). Protect sensitive client information
• Build AI agent systems: Design infrastructure for AI agents that can reason, use tools, and complete multi-step legal tasks independently
• Collaborate closely with engineers, the Q&R (Quality & Research) team, product, and CTO to understand needs and translate research breakthroughs into production features
• Optimize for cost and performance: Ensure we can scale efficiently without burning budget on unnecessary compute

• Significant experience building and operating ML / AI systems in production - you've taken models from research to production and kept them running reliably
• Deep expertise in cloud platforms (Google Cloud and/or AWS) including compute, storage, networking, and managed ML services
• Strong Python skills and experience with the ML ecosystem: scikit-learn, PyTorch / TensorFlow, LangChain, LlamaIndex, or similar frameworks
• Modern JavaScript / TypeScript expertise with React, Next.js, Node.js, and API design - you'll work in our full-stack codebase and build APIs for AI services
• Production Kubernetes experience - deploying, managing, and scaling containerized ML workloads in production environments
• Infrastructure-as-code experience (Terraform,Formation, Pulumi) for managing cloud resources
• Proven track record building CI / CD pipelines for ML systems - automating training, testing, deployment, and monitoring
• Experience with Docker and container orchestration for deploying and scaling ML workloads
• Knowledge of vector databases (Qdrant, Pinecone, Weaviate) and semantic search architectures
• Monitoring and observability expertise (Sentry, Datadog, Prometheus, Grafana, or equivalent)

• Experience with LLM-specific infrastructure (prompt management, fine-tuning pipelines, inference optimization)
• Background in document processing systems (OCR, PDF parsing, layout analysis)
• Familiarity with security and compliance requirements in regulated industries (legal, healthcare, finance)
• Previous experience in early-stage startups or small, high-impact teams
• Contributions to open-source ML tools or frameworks

• User-obsessed: You understand that infrastructure exists to serve end users (lawyers, in our case). You think about reliability from their perspective
• A systems thinker: You see the big picture but obsess over details that matter. You know when to build for scale and when to ship fast
• Radically honest: You call out problems early, debate ideas openly, and help the team make better decisions through transparency
• Infinitely curious: You stay current with ML / AI advances and love experimenting with new tools. You ask "what if?" constantly
• Autonomous and proactive: In a small team, you don't wait for instructions. You identify problems and solve them
• Pragmatic: You balance "perfect" with "shipped." You know when to take shortcuts and when to invest in quality
• A teacher: You document your work, share knowledge, and help others understand complex systems

• €43,000 annual salary

• 100% remote - work from anywhere in Spain
• Flexible hours - we care about output, not hours logged. Manage your own schedule
• Async-first culture with regular team meetups to stay connected
• 28 vacation days
• Flexible retribution via Coverflex (meals, transport, kindergarten, and more)
