OneDigital isseekinga highly capable AI Builder(Harness Engineer) to join our embedded product management ecosystem. This role is responsible fortransforming AI ideas, prototypes, and early-stage builds—often initiated by Product Managers—into scalable, secure, and production-ready applications. 
You will partner closely with Product Managers across the organization who are increasingly hands-on in building AI-driven prototypes. Your role is totake these concepts to the next level, refining, scaling, and operationalizing them into high-quality solutions that can be deployed across OneDigital’s internal and external business lines. 

This is a hands-on role for someone who thrives at the intersection ofAI engineering, product thinking, and rapid experimentation. 

Essential Duties and Responsibilities:

• Partner with embedded Product Managers to interpret business needs, prototypes, and early-stage AI builds 

• Take Product Manager-created concepts or prototypes andevolve them into production-ready AI applications 

• Design, build, and deployend-to-end AI solutions, from refinement through launch

• Develop applications using modern AI tooling, including:

• Front-end builders (e.g.,Replit, cloud-based development environments)

• Hosting and deployment platforms (e.g.,Vercel)

• Internal AI platforms and services

• LLM APIs and orchestration frameworks

• Manage code and collaboration workflows usingGitHub(version control, branching, pull requests, CI/CD practices)

• Evaluate and implement the mostappropriate LLMmodels and architectures based on use case 

• Enhance and scaleAI “co-workers” and workflow automation toolsacross business functions

• Collaborate across internal teams (Marketing, Finance, HR) and external business lines (Employee Benefits, Wealth & Retirement, Financial Services)

• Ensure solutions meetenterprise standards for scalability, security, and performance 

• Continuouslyimprove existing AI solutions through iteration, optimization, and feedback

• Stay current on emerging AI technologies andintroduce new tools and capabilitiesinto the ecosystem

• Product Managers at OneDigital areactively building and prototyping AI solutions—you will partner with them to elevate these into enterprise-grade applications

• You will work across a wide range of use cases, frominternal productivity tools to client-facing AI solutions 

• You will help define how AI is built, scaled, and deployed across the organization

• This is not just an architect role—it is abuilder role with real impact across the business
