Agentic Engineer (Python, LLM Systems)

Spain (Barcelona/Madrid preferred) | Hybrid

€70k–€120k base + bonus + equity

We're supporting one of our clients — a fast-scaling, AI-first product company — in hiring an Agentic Engineer to build and scale production-grade LLM agent systems.

The Role

Our client is building conversational AI and workflow automation systems powered by multi-step agents. They're looking for an engineer who understands that shipping AI systems is fundamentally a systems engineering challenge.

You'll work on:

- Designing and implementing multi-agent workflows (planning, tool-calling, orchestration)
- Building and optimizing RAG pipelines (embeddings, retrieval, context management)
- Managing memory strategies (session handling, summarization, vector search)
- Developing evaluation and monitoring frameworks for agent quality
- Improving latency, reliability, and cost-efficiency of LLM workloads
- Ensuring observability and robustness in production environments

What They're Looking For

- Strong backend engineering foundation (Python preferred)
- Experience building LLM-powered systems in production
- Hands-on work with agents, RAG, embeddings,



or orchestration frameworks
- Experience with vector databases (Qdrant, Pinecone, Weaviate, etc.)
- Cloud-native experience (AWS or similar, containerized services, infra-as-code)
- Product mindset — able to ship, iterate, and improve quickly

Bonus if you've worked on:

- Multi-agent systems
- Evaluation pipelines or hallucination control
- Latency-sensitive AI systems
- Scaling conversational AI infrastructure

What This Role Is Not

- Not a pure ML research position
- Not a fine-tuning-heavy role
- Not just wrapping OpenAI APIs

Our client is looking for engineers who have already built real AI systems and want to push them further.

Compensation & Setup

- €70k–€100k base (versátil for exceptional profiles)
- Performance bonus structure
- Meaningful equity
- Hybrid model (4 in-office days per month)

If you've already built LLM agents in production and want to go deeper into orchestration, evaluation, and scalable AI systems, we'd love to speak.
