Ubiminds is assisting a fast-growing, API-first technology and data company building modern quoting, enrollment, and member-management products for the health insurance and employee benefits space. They are scaling their engineering organization and launching new ML/AI-powered capabilities across their platform. Challenge We’re looking for a ML/AI Engineer to lead the company’s ML/AI engineering initiatives from the ground up. You will be the first dedicated ML/AI engineer, driving the vision, roadmap, and technical execution of intelligent features across multiple products. This is a high-impact, founder-type role for someone who enjoys ambiguity, technical leadership, and building 0→1 systems inside a mature engineering team. The engineering organization values high-quality code, strong collaboration, and disciplined software practices such as TDD, pair programming, static analysis, and defined architectural standards. You will work closely with Product, Ops, and cross-functional engineering squads to identify high-ROI AI opportunities and bring them to production. Responsibilities - Lead all ML/AI engineering efforts as the first dedicated member of this domain. - Design, build, and ship ML/AI-powered features across multiple products. - Partner closely with Product, Engineering, and Operations to identify high-value opportunities and convert them into production systems. - Own the full lifecycle of ML solutions: problem framing, prototyping, modeling, deployment, monitoring, and continuous improvement. - Establish best practices, tooling, and standards for ML/AI development, experimentation, and observability. - Build and improve data pipelines and feature stores to support robust ML workloads. - Collaborate in architecture reviews, roadmapping, and cross-team planning. - Mentor other engineers on ML/AI concepts and help grow the ML/AI team as the practice scales. - Contribute to a high-quality codebase using TDD, code review, and well-structured engineering practices. Mandatory Skills - Strong track record of building and launching ML/AI systems in production environments (not only prototypes or research). - Experience across the entire ML lifecycle: data preparation, modeling, evaluation, deployment, and monitoring. - Hands-on experience with modern AI approaches such as LLMs, retrieval-augmented generation, and/or traditional ML algorithms. - 8–10+ years of software or ML engineering experience. - Proficiency in at least one major ML/AI development language (Python preferred). - Comfortable collaborating in a polyglot engineering environment (team heavily uses Ruby). - Experience building from 0→1 in ambiguous environments with high autonomy. - Strong communication skills and enthusiasm for transparent, positive collaboration.
Nice to Have
Experience designing ML feature stores, embedding retrieval systems, or ML observability frameworks.
