Requirements:

• Strong software engineering experience, with the ability to take problems from technical design through to production; Python and SQL experience are particularly relevant

• Develop and deploy agentic workflows for use cases such as account research, outbound personalisation, call summarisation, and CRM hygiene
• Write production-quality code and build integrations, data pipelines, and services to take solutions from prototype to reliable daily use
• Optimise systems for quality, latency, and cost through evaluation, prompt design, model selection, routing, caching, context management, and token optimisation
• Establish practical patterns for building AI systems at Paddle, including monitoring, guardrails, documentation, and clear measures of business impact
• Own the full lifecycle of solutions, including evaluation, observability, reliability, and cost optimisation
