Senior AI Engineer - LLM & Agent Architect, Security

Checkmarx; Braga; Presencial; EUR 90 000 - 120 000; Tempo integral

Resumo da oferta

Checkmarx is seeking a Senior AI Engineer to join our R&D teams building the AI-driven core of our product. You will work on LLM-powered pipelines and agent-based systems to detect and remediate security risk at scale, grounding model behavior in our product data.

The role requires hands-on experience with LLMs, RAG, cloud AI services, and Go or Python, plus strong testing, CI/CD, and observability skills. You will influence tool selection and architecture while delivering production-grade AI

Qualificações

• 5+ years of professional software engineering experience with LLMs and AI agents.
• Experience designing RAG pipelines, retrieval strategies, or memory systems for LLM applications.
• Practical experience evaluating model and agent quality (accuracy, hallucination, latency, cost) and using evals to guide decisions.
• A demonstrated habit of evaluating and comparing AI tools, models, or vendors, with informed opinions on tradeoffs.
• Experience with cloud AI services (AWS Bedrock, Azure OpenAI, Vertex AI).
• Strong proficiency in Go and/or Python.
• Solid understanding of distributed systems (message queues, gRPC/REST APIs, relational databases) and experience with Docker/Kubernetes.
• Strong testing, CI/CD, and observability fundamentals.
• Excellent English communication skills.

Responsabilidades

• Design, build, and own LLM-powered pipelines and agent-based systems that find, triage, and remediate security risk in production, at scale
• Design retrieval and context strategies (RAG, tool use, memory) that ground model behavior in our product's data and domain
• Define and run evaluations for model/agent quality and use them to drive iteration and model selection
• Evaluate emerging AI tools, models, and frameworks against our product needs, producing clear build-vs-buy-vs-integrate recommendations for the team and leadership
• Stay ahead of the AI landscape: new LLM releases, agent architectures, orchestration frameworks, and techniques and translate relevant developments into concrete engineering proposals
• Own the reliability of AI features in production: guardrails, structured output validation, fallback behavior, and observability tuned for LLM-based systems
• Participate in design discussions and code reviews, bringing an AI-informed perspective to architecture decisions
