About the Job

Requirements

  • A qualification in Computer Engineering, Systems Engineering, Mathematics, Physics, or an equivalent technical area.
  • At least three years of experience, including at least two years working with AI/ML systems in production with real users.
  • Ability to architect an AI data layer covering ingestion, storage, quality, versioning, and access.
  • Strong command of at least one backend language such as Python, Go, Rust, or an equivalent, and experience with agents, integrations, and complex pipelines.
  • Practical experience with production LLMs, including tool-calling, structured outputs, context management, and cost and latency management.
  • Experience architecting agents with multi-step reasoning, memory, tool ecosystems, and fallback.
  • Experience orchestrating frontier, open-source, and fine-tuned models and understanding their trade-offs.
  • Experience with AI infrastructure, including GPUs, model serving such as vLLM or TGI, inference pipelines, and cloud versus on-premises compute.
  • Experience integrating data from multiple sources.
  • Ability to think systemically and critically, work with ambiguity, and communicate clearly to non-technical audiences.
  • Portuguese is required, along with technical English.

Responsibilities

  • Design and maintain the AI Engineering data architecture, including how data is ingested, stored, versioned, and accessed.
  • Ensure data sovereignty so critical data remains within the perimeter.
  • Curate and structure messy data from multiple sources.
  • Build ingestion, transformation, and quality pipelines so data is clean before it reaches models.
  • Structure data for reasoning using knowledge graphs, embeddings, retrieval-augmented generation, and context injection.
  • Architect, design, and build intelligent systems based on large language models for specific domains.
  • Design cognitive architectures, knowledge representation, prompt architecture, tool ecosystems, context, and memory.
  • Orchestrate frontier, open-source, and fine-tuned models based on cost, latency, quality, and privacy.
  • Prototype rapidly and take proofs of concept into product.
  • Design guardrails, fallback behavior, and graceful degradation to address hallucinations, context loss, and confusion.
  • Design evaluations and red-team tests, test edge cases, and measure reasoning quality in addition to accuracy.

Desired Qualifications

  • Experience with LLMOps, including model versioning, monitoring, deployment, and evaluation pipelines.
  • Experience with Google Cloud Platform and Docker.
  • Background in complex domains such as defense, space, energy, or critical infrastructure.

About the Company

CEiiA

Engineering center for sustainable high-tech products

CEiiA is an engineering and product development center that conceives, develops, and productizes new technologies and services to support a more sustainable society. It runs collaborative programs that connect cities, industry, and universities to research, design, prototype, validate, and industrialize products from concept to scalable production in mobility, aeronautics, and space in Portugal. Unlike firms that work alone, CEiiA acts as a bridge among cities, industry, and universities, coordinating multi-stakeholder, large-scale development and local industrialization. Its goal is to turn innovative ideas into market-ready technologies and services through collaborative development and industrialization for a sustainable future.
