Company Description

$28M fintech startup building AI-powered infrastructure for the $20T alternative asset market, backed by Apollo and Motive Ventures

Job Description

As the first dedicated AI hire, you will define how artificial intelligence transforms alternative asset management. Operating in a high-intensity environment with leaders from KKR and Goldman Sachs, you’ll design and ship agentic workflows and document intelligence features that solve complex infrastructure challenges for a rapidly scaling global industry.

Location

London, UK

Why this role is remarkable

• Foundational AI position: As the first specialist hire, you own the AI roadmap and architecture rather than just executing pre-defined feature tickets.
• Elite pedigree: Work alongside a founding team from KKR, Blackstone, and Revolut, backed by $28M from top-tier investors like Apollo and Picus Capital.
• Tangible impact: Build the “AltOS” operating system for an industry expected to hit $60T in AuM, replacing legacy manual processes with sophisticated AI orchestration.

What You Will Do

• Design and build production-grade AI features using AWS Bedrock, Anthropic SDK, and multi-agent orchestration to automate complex investment workflows.
• Partner directly with product leadership to rapidly prototype and move intelligence-driven concepts from initial ideation to live production environments.
• Take end-to-end ownership of the AI practice, establishing how RAG, document intelligence, and LLMs are integrated across the entire AltOS platform.

The ideal candidate

• A proven builder with a portfolio of shipped LLM-powered tools, fine-tuned models, or sophisticated agent pipelines that solve real-world problems.
• Strong technical proficiency in modern back-end systems (Java 21/Spring Boot) and AI tooling (AWS Bedrock, RAG, Knowledge Bases) with a first-principles mindset.
• Thrives in high-intensity, low-structure environments and possesses the drive to go beyond a job description to solve genuinely hard technical challenges.
