Wiser Solutions is hiring a Principal Machine Learning Engineer to define and execute its AI and data science strategy. This senior technical leadership role combines deep expertise in ML, data science, and production engineering with the business acumen to translate technical capabilities into tangible customer value. You will act as the technical authority for AI at Wiser.
What You'll Do
- 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 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 for AI solutions.
- Bridge classical data science approaches 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.
- Mentor and elevate the AI/data science team (3-5 engineers).
- 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.
- Help build an engineering culture where AI augmentation is the default.
What We're Looking For
- 15+ years of experience in data science, machine learning, or ML engineering, with progression into technical leadership.
- Deep expertise in statistical methods, experimental design, and classical ML.
- Proven ability to architect and deliver production ML/AI systems at scale on cloud platforms (AWS strongly preferred).
- Strong software engineering fundamentals: writes production-quality code.
- 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).
- 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.
Nice to Have
- 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.
Technical Stack
