Job Title

Staff AI Engineer

Salary

£120k-£150k + Equity

Company Description

$6.5M Seed-stage Agentic AI platform led by Salesforce Ventures

Job Description

As the most senior AI hire, you will architect a sophisticated multi-agent orchestration layer for regulated financial institutions. Moving beyond simple wrappers, you'll solve high-stakes technical challenges in document intelligence, automated underwriting, and hallucination detection. This is a hands-on leadership role shaping the future of a platform already trusted by marquee enterprise banks.

Location

London, UK

Why this role is remarkable

• Lead AI strategy at a startup that scaled from MVP to paying enterprise customers like Metro Bank in under a year, targeting a $36 trillion industry.
• Work directly with a founding team of former Mambu, McKinsey, and Accenture leaders who have previously scaled fintech valuations from €1.9bn to €4.7bn.
• Tackle genuinely hard engineering problems in a high-stakes regulated environment where accuracy, explainability, and multi-step reasoning are mission-critical requirements.

What You Will Do

• Design and own the core agentic orchestration engine that coordinates dozens of specialized agents across complex financial lifecycles and human-in-the-loop workflows.
• Build advanced NLP and OCR pipelines to extract structured reasoning and data from messy financial paperwork, bank statements, and 200-page credit memos.
• Establish rigorous evaluation and alignment frameworks to ensure auditable AI decision trails, meeting the strict trust thresholds required by global financial institutions.

The ideal candidate

• Deep hands-on expertise shipping production-grade AI systems, specifically focusing on NLP, agentic architectures, or information extraction rather than just basic API integration.
• Strong research instinct and architectural judgment, capable of translating emerging techniques in hallucination detection and structured reasoning into reliable, scalable production code.
• Proven ability to operate with high ownership in a fast-paced environment, making consequential technical decisions while contributing as a high-impact individual programmer every day.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
