We’re building an AI intelligence infrastructure embedded inside a B2B platform used by consumer brands to manage creative work, assets, and workflows.

This infrastructure is designed to support a wide range of intelligent and intuitive product features, including (but not limited to) conversational interfaces, image generation, contextual recommendations, automation, analysis, and decision support.

Senior AI Systems Architect

We’re looking for a senior AI Systems Architect to design the foundational intelligence layer that powers these capabilities in a way that is reliable, evolvable, and cost‑controlled.

Responsibilities

You will own the design of the AI intelligence layer and this includes:

  • Designing a clear intelligence architecture that supports multiple AI‑driven features
  • Defining a robust memory taxonomy (short‑term, long‑term, client‑level, org‑level, and meta memory)
  • Designing RAG‑based retrieval systems that serve different product use cases
  • Defining retrieval + reasoning flows that adapt to intent, context, and confidence
  • Establishing failure handling and guardrail strategies for production AI systems
  • Designing idempotent AI workflows for actions, updates, and automation
  • Establishing cost controls, usage boundaries, and observability
  • Designing evaluation and feedback loops so intelligence improves through use
Deliverables
  • Memory schemas and retrieval strategies
  • Interface contracts and reference patterns for implementation
  • A Phase‑2 build plan outlining how intelligence evolves post‑MVP
What You'll Not Do
  • Building UI or frontend features
  • Acting as a generalist full‑stack developer
  • Shipping one‑off demos or prototypes
  • Writing large amounts of production code
  • Optimizing prompts in isolation from system design
Desired Profile
  • Have designed AI intelligence systems inside real products
  • Think in terms of systems, state, and failure modes
  • Are fluent in RAG, memory design, and retrieval strategies
  • Care deeply about idempotency, reliability, and cost control
  • Can guide engineers through clear abstractions and contracts
  • Fractional / Contract
  • 10–20 hours per week
  • Opportunity for full‑time employment
How to Apply
  • Examples of production AI systems you’ve architected
  • How you think about memory, retrieval, and reasoning
  • Any diagrams, writing, or artifacts that show your system‑level thinking
