Job Description

Get AI-powered advice on this job and more exclusive features.

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.

This is not a chatbot project.

This is not a ChatGPT wrapper.

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 you think about memory, retrieval, and reasoning

Any diagrams, writing, or artifacts that show your system‑level thinking
