Artificial Intelligence Engineer - London - £120k
About the Company
A stealth-mode, venture-backed startup is building intelligent agent-based systems that help fintechs and financial institutions automate high-stakes decision-making. Their platform is already in use by clients, combining structured data, generative AI, and smart workflows to transform how businesses manage risk.
About the Role
This is an opportunity to join as the founding AI engineer, take full technical ownership, and build both the architecture and product from the ground up. You'll work directly with experienced founders (ex-European fintech and risk platforms) to create the core engine of a platform designed for real-world scale and compliance.
Responsibilities
- Architect and build LLM-powered agents to support decision-making in regulated environments
- Improve and extend an existing system already in production
- Lead the development of a brand-new, greenfield AI product
- Choose and implement the infrastructure, models, and tooling stack
- Balance experimentation with delivering robust, audit-friendly systems
- Operate as a true founding engineer — with high autonomy, trust, and equity
Qualifications
- 7+ years of experience in AI/ML engineering or backend systems with a strong applied AI focus
- Proven experience deploying LLMs or agent-based systems in production
- Strong Python skills (must-have)
- Solid grasp of system design, architecture, and model integration
- Startup-ready mindset: proactive, pragmatic, and comfortable owning delivery
- Interest in working in a lean, fast-moving, early-stage environment
Required Skills
- B2B SaaS, fintech, or regulated industry background
- Familiarity with retrieval-augmented generation (RAG), vector stores, or agentic design patterns
- JavaScript experience
- Founding engineer or early startup hire experience
