AI Engineer - RAG & AI Agents

  • Indefinite
  • Full time
  • Remote
  • Research & Development

Iris.ai is a pioneering AI-first company on a mission to transform how humans discover and apply knowledge. For over a decade, we’ve built intelligent systems that empower researchers, engineers, and product teams to work faster and more precisely with scientific and technical data.

Our product suite — Neuralith, Axion, and RSpace — supports end-to-end AI development, from data orchestration and retrieval to LLM evaluation and deployment. At the core of our work are Retrieval-Augmented Generation (RAG) pipelines, LLM Evaluation Frameworks, and intelligent AI Agents that bring context-awareness, accuracy, and task-level reasoning to applied AI.

Backed by the European Innovation Council (EIC) and trusted by leading R&D teams across industries, we turn advanced AI research into real-world tools that help organizations solve high-impact problems.


Opportunity:

As an AI Engineer at Iris.ai, you’ll join a remote-first, AI-native team focused on building production-ready systems powered by RAG, LLMs, and AI agents. You’ll collaborate with research scientists, engineers, and product managers to design and deliver AI features that go beyond generation — helping users navigate, reason, and act on complex knowledge.

You’ll work across the full development lifecycle, from design to deployment, and play a key role in shaping how next-gen AI is evaluated, trusted, and adopted in real-world workflows.


Technologies used in the job include:

  • Python & Django
  • Relational databases (PostgreSQL)
  • Non-relational and vector databases (Elasticsearch / OpenSearch, ChromaDB, Couchbase)
  • AI / ML / NLP libraries (Gensim, Torch, Transformers, spaCy, Autogen, etc.)
  • Cloud (AWS)
  • GenAI tools (Windsurf, Cursor, Amazon Q, Claude and other)
  • Git & CI / CD


WHAT YOU’LL DO:

  • Own the full development lifecycle — from idea to architecture, implementation, testing, and delivery of real-world AI products
  • Design and build robust AI systems, including Iris.ai’s proprietary Retrieval-Augmented Generation (RAG) pipelines and LLM Evaluation Frameworks used by leading R&D teams
  • Drive innovation by testing new approaches and bringing new AI research into production
  • Collaborate across teams — work closely with researchers, product managers, and fellow engineers to shape and ship powerful features
  • Build systems for performance and reliability, ensuring they are scalable, testable, and maintainable
  • Contribute to a global mission to transform how the world interacts with scientific knowledge and applied AI
  • Thrive in a remote-first, agile environment, contributing meaningfully within a distributed, deep-tech team
  • Keep learning, always — we’ll support you with space, mentorship, and resources to grow as an AI engineer

What you need:

  • 5+ years in software development, including 3+ years with Python
  • Solid experience in web backends (Django/Flask), REST APIs, databases, and cloud infrastructure
  • Familiarity with ML systems or motivation to learn in depth
  • Ability to work in a remote-first, collaborative environment
  • Proficiency in English


Any of these is an advantage:

  • Advanced degree in Computer Science or related field
  • Previous work with LLMs, NLP, or AI model evaluation
  • Experience contributing to or using RAG systems in production
  • Open-source contributions, academic research, or mentoring
