Hiring remotely in the UK / Europe (GMT to GMT+2)

We’re looking for a Senior AI Engineer to join our distributed team at Graphy. We have existing AI features and agents, but you’ll help us take them to the next level, improving the accuracy, scalability and reliability (think Cursor level).

You’ll architect an AI API that includes agents, multi-agent orchestration and AI-powered tools. You’ll also build AI features that integrate seamlessly with our SDK (think charts and graphs with AI magic on top).

What we look for

• Proven ability to build production AI features that are reliable, scalable and solve real user problems. Not just prototypes.
• Experience designing and shipping complex AI systems (agents, classifiers, chat-like experiences, multi-step workflows).
• Strong product engineering fundamentals. We use TS/Node, but we’re open to engineers coming from other stacks such as Python.
• Familiarity with multiple providers and models (Anthropic, OpenAI etc), understanding the tradeoffs and knowing how to evaluate and test them properly.
• Experience building backend APIs (REST and / or MCP) around AI functionality.
• Infrastructure and observability mindset. You know how to build scalable AI products and features.
• Pragmatism and ability to balance speed and quality well, avoiding both over-engineering and shortcuts that create long-term problems.
• Strong communication skills. Someone who can share knowledge clearly, help others level up and work well in an async environment.

What you will do

You’ll build build robust AI agents and AI-powered features (aiming for Cursor-level reliability) as well as:

• Architect multi-agent systems where each agent excels at one thing, plus the orchestration between them (e.g. the supervisor pattern).
• Solve complex accuracy and reliability challenges through iteration and proper evaling.
• Build infrastructure around AI (monitoring, traces, gateways, logging etc).
