AI Product Engineer - Internal Tools & GPT Systems

Posted by Bowleys Estate Agents.

**About the Role

We're looking for a technically sharp AI Product Engineer to help us build and scale the internal systems that power a new kind of decision intelligence company.

You'll work closely with the founder and our technical architect to turn structured logic into operational tools — using ChatGPT (OpenAI) and advanced workflows to build agent-based systems, internal dashboards, and strategic infrastructure.

This isn't prompt hacking. This is structured architecture.

If you're excited about building GPT-powered systems behind the scenes — not for content, but for control and clarity — you'll thrive here.

**Your Responsibilities

  • Build and maintain internal tools for workflow management, decision logic, and automation.
  • Develop and test GPT-based workflows using OpenAI's API and related tooling.
  • Translate structured frameworks into code-based systems — working from strategic diagrams, logic trees, and behavioural patterns.
  • Collaborate with product, strategy, and technical teams to deploy clean, scalable solutions.
  • Ensure outputs are consistent, version-controlled, and compounding over time.

**You Should Have

  • Strong proficiency in Python and/or JavaScript/TypeScript.
  • Experience with OpenAI APIs, LangChain, or similar LLM orchestration tools.
  • Strong understanding of prompt structure, system design, and GPT behaviour tuning.
  • Ability to build simple internal UIs or backend logic (no full-stack required).
  • Excellent communication and ability to think like a systems architect, not just a coder.

**Bonus If You Have

  • Experience building internal AI tools or agent-based workflows.
  • Familiarity with vector stores, embeddings, and chaining frameworks.
  • A mindset obsessed with structure, reuse, and long-term IP value.
  • A portfolio or code samples that demonstrate clarity and architectural thinking.

**Why This Matters

We're building something that sits between AI tooling, decision science, and behavioural strategy — and the core value lies in how we structure and deploy our systems, not just in what they say.

You'll help build foundational systems that no one sees — but that power everything.

**Process

  • Submit CV + short note (1-2 paragraphs) on why this interests you.
  • Shortlisted candidates will receive a micro-task or technical logic test.
  • Interviews follow for cultural/technical fit. We hire fast and iterate together.

**Apply Now

We're reviewing applications on a rolling basis. If you're technically excellent, strategically minded, and excited by building AI systems that go deeper than chatbots — we'd love to hear from you.
