Director of AI Product Engineering (Agentic AI, Architecture & SaaS) Compensation: $240,000 base + approximately $20,000 bonus Location: Remote, US The Company An established, PE-backed B2B SaaS company operating in a regulated market is making AI a core part of its product strategy. The business has a substantial existing customer base, multiple production platforms, and a roadmap moving from relatively straightforward LLM applications toward more sophisticated agentic systems and AI infrastructure. The Opportunity This is a high-impact architecture role for someone who wants director-level technical influence without stepping away from the code. You will define how customer-facing AI is built across an established product portfolio while helping a broader engineering organization adopt stronger agentic, evaluation, context, and governance patterns. The Role You will own end-to-end architecture for the company’s customer-facing AI capabilities and lead a small senior AI team. This is explicitly a player-coach position: you will make major technical decisions, build reference implementations, work directly in the codebase, and enable product engineering teams to ship production AI safely at scale. What You’ll Do • Own architecture across agentic workflows, compliance-focused AI, content generation, retrieval, memory, context, and other customer-facing AI capabilities. • Design agent architectures, orchestration patterns, MCP integrations, reusable context standards, and reference implementations for wider engineering teams. • Establish rigorous evaluation methodologies and quality standards for production AI features. • Lead build-versus-buy decisions covering models, infrastructure, hosting, evaluation, and supporting AI platforms. • Partner with product and platform engineering teams to prototype capabilities, move them into production, and transfer ownership without becoming a bottleneck. • Define technical approaches to data governance, tenant isolation, model hosting, privacy, cost management, and enterprise AI requirements. • Coach engineers through architecture reviews, workshops, demos, and hands-on collaboration while continuing to write production code. What You’ll Bring • 10+ years of software engineering experience, including senior technical ownership of a production AI product. • Proven experience designing and shipping agentic systems involving orchestration, tool use, multi-step workflows, memory, or context management. • Current hands-on knowledge of LLM application architecture, retrieval, evaluation, prompt/context engineering, and production AI systems. • Experience operating at SaaS scale and improving existing products and architectures rather than working exclusively on greenfield systems. • Ability to communicate complex architecture clearly to engineers, product teams, executives, and non-engineering stakeholders. • A collaborative player-coach approach: comfortable setting technical direction while building relationships, mentoring teams, and working through regulatory or organizational constraints. What This Role Requires • 10+ years of software engineering experience with senior ownership of a production AI product. • Hands-on delivery of production agentic systems used by customers. • Current fluency across LLM application architecture and evaluation. • A genuine desire to remain hands-on in the code while operating at director level. Tech Stack • OpenAI and Anthropic models • Weaviate vector search • MCP and agent integration architecture • Retrieval, memory and context systems • Knowledge graphs and ontologies • AI evaluation infrastructure and methodologies • AWS Bedrock under consideration as part of the future hosting strategy Why Join • Own one of the most strategically important technical areas in the business, with meaningful authority over AI architecture across multiple product teams. • Work on real production challenges across agents, retrieval, knowledge graphs, evaluation, privacy, governance, and AI infrastructure rather than isolated prototypes. • Keep building while operating at leadership level, with the opportunity to raise the technical standard for AI across a substantial engineering organization.
