Act as a subject matter expert in Analytics: Strong understanding of statistics, experimental design, and hypothesis testing to identify trends and patterns, and develop predictive models
Design and deploy Agentic AI systems capable of autonomous, multi-step reasoning, e.g. such as agents that categorise financial transactions by searching for merchant information, applying labels, and surfacing confidence scores with transparent reasoning
Lead data labeling at scale to produce ground-truth datasets and use ML techniques to maximise labelling efficiency
Build AI agents that integrate with external tools and data sources via protocols such as MCP, enabling LLMs to interact directly with codebases, APIs, or internal systems to automate complex workflows
Lead model deployment with an eye for performance, scalability, and real time low-latency inference
Deliver robust, low-failure-rate models and systems, especially in environments where testing support is limited
Collaborative Problem Solving: Work closely with cross-functional teams, including product, engineering, and business stakeholders, to understand requirements and deliver data-driven solutions
Enthusiasm for collaborating across disciplines, including with academic researchers and third-party partners
