What you'll do

  • Analyze business needs and processes to define automation use cases and task split between agent autonomy and human validation
  • Design and develop complete agentic systems, choosing between custom development and low-code/no-code configuration
  • Build agent tools: function calling, API and information system integration, MCP servers, asynchronous long-running workflows
  • Ensure reliability: error handling and retries, control loops, budget and step limits, behavior facing the unexpected
  • Evaluate agents: scenario sets, trajectory analysis, task success rates, LLM-as-judge, non-regression tests
  • Observe in production: detailed traces, cost per task, drift and loop detection, dashboards
  • Secure autonomy: least-privilege tool permissions, prompt injection protection, isolation of sensitive actions, human validation, compliance
  • Integrate into the full SDLC and deploy on the cloud with CI/CD and cost management
  • Share: document patterns, train client teams, contribute to SFEIR publications and events

What we're looking for

  • 5 years of software development experience (excluding internships and apprenticeships) with cross-functional SDLC vision and solid LLM/AI project experience
  • Demonstrated practice creating AI agents: custom development or via low-code/no-code environments
  • Knowledge of MCP and inter-agent interoperability protocols (A2A)
  • Fine understanding of agent failure modes: drift, loops, wrong tool choice, context loss
  • Strong command of APIs, asynchronous and event-driven architectures
  • Engineering rigor: tests, observability, reviewed code
  • Interpersonal ease and good functional level to exchange with business teams and explain AI agent possibilities and limits

Nice to have

  • Experience with agent evaluation and observability (OpenTelemetry, Langfuse...)
  • Knowledge of the BMAD methodology
  • Google Cloud (Vertex AI, Cloud Run, Gemini)
  • Security sensibility: agent threat models, identity and permission management
  • RAG notions, seen as an agent tool
  • Open source contributions, agentic side projects, talks
