Project description

SKILLS

Must have

  • AI agents:
  • Daily work with coding agents (Claude Code, Cursor, Codex or similar) as your main way of writing code, not an experiment.
  • Understanding of how LLM agents work: context, tools, planning, subagents, typical failure modes.
  • Ability to review agent output quickly and critically, catching errors and hallucinations. Engineering background:
  • 5+ years of professional software development as a full stack developer, with systems taken to production and supported there.
  • Relational databases and SQL; understanding of graph data models (Neo4j) and vector databases.
  • Docker, Kubernetes, Helm: you deploy and debug them yourself.
  • Testing as a habit: unit and integration tests, Testcontainers or similar.
  • Understanding of TDD aspects. Soft skills:
  • Owning an area on your own, from an unclear problem statement to production, without someone else breaking it into tasks.
  • Willingness to make decisions with incomplete information and to own the outcome.
  • Ability to get up to speed quickly in unfamiliar code, technology or business domains.
  • Ability to explain a decision and its limits in writing and in person.

Nice to have

• Experience with LLM provider APIs (Anthropic, OpenAI, Bedrock) or a gateway such as LiteLLM. • R&D experience: hypotheses, prototypes, experiments and data-driven decisions on problems with no known answer. • Mainframe: COBOL, CICS, JCL, DB2, IMS, PL/I, HLASM, CA Gen, z/TPF; 3270 and z/OSMF. • Experience building evals for non-deterministic systems: regression suites, metrics, comparison of models and prompts. • Knowledge of threats to agents and the code they write: prompt injection, secret leakage, excessive permissions, poisoned dependencies and MCP servers (OWASP Top 10 for Agentic Applications). • Secure work with coding agents.
