About the Role
A fast-growing creative agency is building an AI-first internal operating system - and we're looking for a high-impact Prompt Engineer & AI Systems Manager to help shape and deliver it. This role focuses on internal systems that power business operations, sales enablement, and marketing automation through the use of GPT models and low-code tools.
This is a delivery-focused role ideal for someone with a background in internal automation, AI systems architecture, and prompt engineering. You'll collaborate cross-functionally with Sales, Operations, Delivery, and Leadership teams to create, refine, and scale AI-powered workflows.
While initially offered as a three-month engagement, there is strong potential for extension based on performance and business needs.
Key Responsibilities
AI Systems Ownership
Maintain and evolve the internal AI Operating System.
Lead structured weekly reviews of GPT usage, implementation feedback, and performance metrics across departments.
Prompt & Schema Engineering
Design, refine, and optimise structured GPT prompts to support use cases such as proposal QA, CRM triggers, reporting, and internal workflows.
Ensure schema logic, tone, and functional performance are consistently high-quality.
Cross-Functional Enablement
Collaborate with internal teams to develop and roll out tailored GPT-based tools.
Own briefing, configuration, and deployment processes to ensure smooth adoption and value delivery.
Automation Stack Management
Maintain and optimize the automation engine using tools like Zapier, Make, HubSpot, Notion, Clay, and Airtable.
Ensure all tools work in alignment with system architecture and team needs.
AI Feedback Looping
Gather user feedback across GPT tools and systems.
Translate insights into prompt enhancements, system updates, and change logs.
Documentation & Transparency
Create and maintain clear documentation in Notion for all prompt logic, systems architecture, and automation logic.
Ensure systems are easy to inherit, adapt, and scale.
Innovation & System Evolution
Identify opportunities to modularize, improve, or re-architect systems based on emerging technologies and team feedback.
Proactively propose improvements to keep AI infrastructure sharp and scalable.
What We're Looking For
Must-Haves
3-5 years of experience in technical product operations, internal tooling, or workflow automation
Demonstrated experience in prompt engineering with tools like ChatGPT or other LLMs
Proficiency with low-code automation platforms (e.g. Zapier, Make, Airtable, Notion, HubSpot)
Strong operational discipline: cadence-driven, feedback-oriented, and systems-minded
Attention to detail in documentation and handover readiness
Ability to translate friction points into practical system improvements
Nice-to-Haves
Experience in agency, startup, or creator-tech environments
Familiarity with LangChain, vector search, or building internal GPT-based apps
Comfortable operating in a hybrid technical/ops role
Experience using AI or automation to streamline internal workflows
Why This Role Matters
This is not about layering AI onto outdated systems - it's about building a modular, intelligent operational foundation from scratch. Your contributions will directly power internal performance, scalability, and innovation.
