Job Level

About the role

  • Define and evolve Wiser's AI and data science technical strategy in partnership with product and business leadership
  • Represent Wiser's AI capabilities to customers, partners, and advisors—articulating our approach, roadmap, and differentiation
  • Identify high-impact opportunities where AI can solve customer problems or create competitive advantage
  • Establish technical standards, patterns, and best practices that influence engineering decisions across the organization
  • Architect and build production AI systems including LLM applications, RAG pipelines, semantic search, and traditional ML models
  • Design rigorous evaluation frameworks, experimentation methodologies, and monitoring systems that ensure AI solutions deliver reliable, measurable results
  • Bridge classical data science approaches (statistical modeling, experimentation design, feature engineering) with modern generative AI techniques
  • Own technical quality for AI systems end-to-end: from data pipelines through model deployment to production observability
  • Partner with product management to translate business requirements into technical approaches and validate solutions against customer needs
  • Mentor and elevate the AI/data science team (3-5 engineers), raising the technical bar through code review, architecture guidance, and knowledge transfer
  • Collaborate across engineering teams to integrate AI capabilities into Wiser's broader platform architecture
  • Drive build-vs-buy decisions and vendor evaluations for AI infrastructure and tooling
  • Champion AI-native development practices across Wiser engineering—demonstrating how AI tools accelerate development, improve code quality, and change what's possible
  • Help build an engineering culture where AI augmentation is the default, not the exception

Requirements

  • 15+ years of experience in data science, machine learning, or ML engineering, with demonstrated progression into technical leadership
  • Deep expertise in statistical methods, experimental design, and classical ML (not just LLM integration)
  • Proven ability to architect and deliver production ML/AI systems at scale on cloud platforms (AWS strongly preferred)
  • Strong software engineering fundamentals: you write production-quality code, not just notebooks
  • Track record of organization-wide technical influence—setting standards, driving architectural decisions, mentoring engineers
  • Experience communicating technical strategy and capabilities to non-technical stakeholders, including customers and executives
  • Demonstrated ability to operate autonomously, identify high-impact problems, and drive initiatives without close direction
  • Active, daily use of AI coding assistants (Cursor, Claude Code, GitHub Copilot) and a demonstrated belief that AI fundamentally changes how software gets built.
  • Technical Depth Expected: NLP and text analytics: embeddings, semantic similarity, classification, entity extraction, and information retrieval
  • LLM integration patterns: prompt engineering, RAG architectures, agent frameworks, evaluation methods
  • Data engineering: pipeline design, data quality, feature stores, and working with large-scale datasets
  • MLOps: model deployment, monitoring, A/B testing infrastructure, and production observability
  • Python ecosystem mastery; SQL fluency; comfort with distributed systems concepts
  • Preferred: Experience with transformer architectures, fine-tuning, or training custom models
  • Background in retail, e-commerce, or product data domains
  • Familiarity with LLM orchestration frameworks (LangChain, LlamaIndex) and vector databases
  • Track record of introducing AI-augmented workflows to teams or organizations
  • Opinions (and evidence) on how AI changes engineering practices, team structures, or development processes
Benefits
  • Performance-based discretionary bonuses and variable pay plans available for some positions
