, we're here to help propel your career and together, make Moss a lasting success.
We're expanding our Data & AI team and looking for a senior/lead contributor who's fluent in classical ML and, as a big plus, has hands-on LLM app/agent experience. You'll own end-to-end ML initiatives - from problem framing and modelling to evaluation, deployment, and iteration - directly improving core product workflows (invoice understanding, approval matching, reconciliation, anomaly detection, and user-assist).

Your Responsibilities

  • Own ML models for classification, ranking, anomaly detection, and recommendations.
  • Define evaluation & monitoring: gold sets, automated tests, robustness checks, SLAs, and cost/latency tracking.
  • Productionise with Platform/Data Eng: bring your models live and iterate/improve until they are adopted by your stakeholders

About You

  • 5-10+ years in applied ML with production ownership of shipping models/systems.
  • Big Plus: Hands-on LLM app/agent experience (tool use/function calling, RAG, structured outputs, guardrails) in production.
  • Strong Python + ML stack (e.g., scikit-learn, XGBoost/LightGBM, PyTorch/TF) and solid experiment/evaluation skills.
  • Strategic Problem Solver: You approach ambiguous problems by deeply understanding business context and framing data science solutions that drive meaningful outcomes. You rigorously validate assumptions, identify root causes, and prioritize solving the right problem before building.
  • End-to-End Executor: You independently own projects from ideation to production, balancing model performance with engineering realities. You ensure solutions are scalable, monitored, and maintained with thoughtful evaluation, deployment, and iteration strategies
