Designs and owns AI solutions, including LLM based applications, classical machine learning models, and hybrid approaches. Builds and operates complex AI systems such as agentic workflows, retrieval augmented generation platforms, document extraction, anomaly detection, and natural language reporting. Evaluates ambiguous business problems and determines appropriate architectures, patterns, and modeling techniques. Defines and implements evaluation strategies, metrics, and feedback loops to measure model effectiveness and business impact. Leads the development of data pipelines, integrations, warehouse models, and evaluation datasets required to support enterprise systems. Integrates with enterprise systems including ERP, payroll, business intelligence, telematics, and collaboration platforms, and implements automated reconciliation and data integrity controls. Owns production readiness, including performance, reliability, cost, observability, and failure handling. Identifies and mitigates risks related to bias, hallucination, data leakage, and unintended AI behavior. Plans and executes system migrations, including data migration, parallel operation, validation, and rollback. Collaborates cross functionally with operations, project management, accounting, human resources, and safety to define requirements and guide solution design. Mentors and provides technical guidance to other team members. Contributes to the establishment and evolution of engineering standards, patterns, documentation, and best practices. Qualifications: Bachelor's degree in Computer Science, Software Engineering, Data Science, or a related technical field, or equivalent practical experience.

Advanced full stack proficiency, including modern web frameworks, a production backend language such as Python, TypeScript, or C#, relational data modeling, SQL, APIs, testing, and system design. Demonstrated experience building offline first or local first applications, including synchronization and conflict resolution. Production mobile development experience on iOS and Android, including enterprise distribution and device management. Advanced proficiency in one or more large scale data platforms such as Snowflake, Databricks, Amazon Redshift, Microsoft Fabric or Synapse, or similar. Strong applied knowledge of machine learning and artificial intelligence concepts, evaluation techniques, and failure modes. Hands on experience designing, building, and deploying LLM based systems using enterprise grade platforms and frameworks. Experience with one or more AI orchestration frameworks such as LangChain, LangGraph, LlamaIndex, Semantic Kernel, or similar. Deep understanding of data quality, feature relevance, and model behavior across structured and unstructured data. Experience building or integrating financial, planning, or forecasting models where accuracy, versioning, and auditability are required. Experience integrating with an ERP or comparable system of record. Experience deploying, monitoring, and iterating on systems in production environments. Working knowledge of enterprise security and access control, including single sign on, multifactor authentication, role based access, and handling of sensitive employee and business data. Ability to make and defend technical tradeoff decisions balancing accuracy, cost, risk, and scalability. Strong communication and leadership skills, with the ability to influence technical direction and mentor others. Experience in construction, utilities, field service, or manufacturing environments preferred. Bilingual English and Spanish preferred. PURIS
