Job summary

Infiterra is seeking a Senior AI Engineer to join R&D and design, build, evaluate and operate production AI systems. You’ll work across LLM-based systems, retrieval, agents, tool use and model adaptation, selecting approaches based on evidence rather than defaulting to one technique.

This is a fully remote senior individual-contributor role based in Greece or the UK, with periodic in-person collaboration; you will own complex AI capabilities end-to-end and mentor other engineers in reusable

Qualifications

• Hands-on experience delivering production AI systems with APIs and tool-based workflows.
• Strong software engineering, Python, distributed systems, CI/CD and cloud.
• Ability to translate complex workflows into reliable system behavior.
• Excellent written and spoken English.

Responsibilities

• Own design, implementation, evaluation and production operation of complex AI systems.
• Translate ambiguous business problems, rules and domain constraints into measurable AI/system behaviour.
• Select the appropriate AI approach based on evidence - including prompting, retrieval, orchestration, predictive ML, model adaptation/fine-tuning or specialized models where justified.
• Build production systems using model APIs, structured outputs, retrieval/RAG, agentic and tool-based workflows, predictive techniques and other appropriate AI patterns.
• Design evaluation strategies covering functional behaviour, groundedness, business correctness, robustness and regressions.
• Establish production monitoring and feedback loops using evaluation evidence, logs, metrics, traces and operational data.
• Engineer for reliability, testability, observability, maintainability, latency and cost.
• Design production learning loops and determine whether behaviour should be improved through context, retrieval, orchestration, model choice, adaptation/fine-tuning or other techniques.
• Diagnose complex AI and software failures and convert production learning into prevention and system improvement.
• Identify and validate AI-enabled improvements to SDLC, Product and operational workflows.
• Explore AI-enabled platform-quality capabilities such as anomaly detection, data-quality/error detection, failure-pattern analysis and intelligent monitoring where they provide measurable value.
• Work with Architecture, Platform, Security, Data, Quality, Product and domain specialists while retaining technical accountability for the AI capability within your scope.
• Mentor less-experienced engineers and contribute reusable patterns, knowledge and practices.
