Sr. AI Engineer – Agentic Systems

Qualifications

• What You'll Bring
• Deep expertise in production Python, with strong working knowledge of current agent frameworks and protocols (Claude Agent SDK, deepagents, LangGraph, MCP, or equivalents)
• Experience building and debugging agentic systems in production, where failure modes are emergent rather than exceptions: loop instability, tool misuse, unbounded context growth, and non-determinism
• A feel for the performance envelope: where latency comes from in a multi-step agent, what a token budget buys, and how to trade quality against both
• Evaluation rigour, and the judgement to design measurement that holds up in a business environment rather than a demonstration
• Fluency with agentic coding tools in your own workflow, such as Claude Code and Codex. The team is fully immersed in this way of engineering, and we expect it to be part of how you build rather than something reached for occasionally
• The profile can come from either direction: a software engineer who has moved into AI systems, or an AI engineer with strong systems fundamentals. Either way we expect engineering discipline, meaning version control, tests, reproducibility, and code the next person can pick up
• Strong Preference Given To
• Evaluation and tracing tooling for agent behaviour (LangSmith, Weights & Biases, or custom solutions)
• Distributed and event-driven systems experience (Kafka or similar)
• Retrieval and memory system design for long-running agents
• Full-stack development experience integrating agents into user-facing applications
