5+ years in a technical or design adjacent role at a tech company, with genuine hands-on experience - whether you came from design and grew into technical depth, or from engineering and developed strong UX and language sensibility
Python you can build in, not just read. You can build, test, debug, and deploy integrations yourself, and meaningfully review what others ship
Demonstrable impact beyond your own projects: patterns other people adopted, an evaluation approach that spread past the work you built it for, colleagues who got materially better because of reviews you ran
Familiarity with LLMs in practice: prompt engineering, tool use, retrieval, context management
Hands-on experience building agentic systems - orchestration, tool-calling, multi-step workflows - and, just as importantly, evaluating them: automated evaluation pipelines and measurement of non-deterministic behaviour
Experience owning external client relationships: challenging unclear requirements and explaining design decisions and trade-offs directly to customers
Meticulous attention to language, tone, consistency, and interaction quality - with the judgement to know when to resolve ambiguity and when to ship anyway
Voice-specific craft: designing around latency, barge-in, ASR errors, and recovery
Experience enabling non-technical users to self-serve on a platform
Knowledge of or aptitude for analytics or data science, including data manipulation, analysis, and visualisation
Background in Linguistics, Interaction Design, Human-Computer Interaction or a related field
