AI Engineer, Agent Systems

Role overview Build and operate AI agents that handle real accounting work within financial systems, from transaction classification to actions in ledger, reconciliation, close, and tax workflows. You will own a defined part of the system from design through production validation, working within established controls and using coding agents as a core part of implementation. Multiple positions are available at different experience levels.

Responsibilities - Take ownership of a system area such as an agent tool family, an integration boundary, or an evaluation framework. - Design, implement, and validate changes against live systems, then maintain them as real-world conditions expose gaps. - Build within existing architecture for confidence policy, action limits, review gates, and tenant separation. - Use coding agents to produce much of the implementation and check the result carefully. - Investigate where system behavior or assumptions do not hold, and communicate issues clearly. - Contribute to software that is already used with real accounting data and has a controlled write path into an ERP.

Requirements - Solid software engineering fundamentals and the ability to take a problem through to a working, integrated result. - Careful reasoning about correctness and the risks of automated actions in financial workflows. - Ability to understand existing system boundaries and work reliably within them. - Comfort using AI coding agents as a required part of day-to-day development. - Clear communication and a willingness to discuss uncertainty, tradeoffs, and lessons from systems you have built.

Nice to have - Experience with accounting, financial systems, or other domains where automated errors have meaningful consequences. - Prior work on integrations, agent tools, or evaluation systems is relevant to the examples of surfaces this role may own, but no specific technology is stated.

Benefits and work setup - Several openings across more than one level; applicants can share their view of their experience level for discussion. - Remote opportunities across the UK, Luxembourg, Portugal, Spain, and elsewhere in the EU. - The selection process uses two conversations: working through a real problem and examining a system the candidate has built. No whiteboard or unpaid project is described.
