What we're looking for

You'll need hands-on AI experience. We're looking for someone who has actually built, tested and troubleshot AI tools or applications, not someone whose experience is limited to talking about them.

You'll bring:

• Hands-on experience building and testing AI tools, applications, labs, simulations, prototypes or API integrations.
• Strong practical understanding of large language models and foundation models, including how they work, their limitations, context and data flows and multimodality.
• Experience with common AI application patterns including RAG, embeddings, vector databases, prompt engineering and fine-tuning.
• Familiarity with agentic systems, tools and actions, workflows, orchestration and MCP.
• Understanding of AI evaluation and safety, including evals, guardrails, moderation, human-in-the-loop approaches and observability.
• Advisory, consulting, solutions engineering or similar experience helping others understand which AI tools or approaches to use and why.
• Strong client-facing experience, including communicating confidently with senior and technical client stakeholders.
• The ability to take complicated technical information and translate it into simple, precise language for different audiences and teams.
• Strong problem decomposition: you can take a vague, high-stakes brief and create clarity without waiting for someone else to define the answer.

How you work

You'll thrive at Quadmark if you're proactive and take ownership. You'll follow an issue through rather than assuming someone else will pick it up and you'll care about the details because technical credibility matters. You're comfortable with ambiguity and patient when helping other people understand complex ideas. At the same time, you're agile and able to move quickly in an environment where both priorities and AI technology can change fast. You're precise about what technology can and can't do. You'd rather qualify a claim than oversell it, and you're comfortable constructively challenging an assumption when the evidence doesn't support it. You'll also be someone who enjoys enabling other people to succeed. This role has no direct reports: your impact comes through your expertise, judgement, communication and ability to make the people around you more effective.

Bonus points

We'd particularly like to hear from you if you have:

• A background in the technology industry.
• Experience in solutions engineering, forward-deployed engineering, applied AI or technical pre-sales.
• Experience in learning, enablement or consultancy.
• Hands-on experience with current developer tools such as Codex, Claude Code or Cursor.
• Experience working with major technology clients or partners.
