Job Description

AI Engineer – Agentic Systems – AI-Native Finance Platform - Hybrid (London area) – Permanent – Competitive Salary + Equity

A well-funded early-stage B2B SaaS company is hiring an AI Engineer to take ownership of its agent orchestration layer and help build a multi-agent platform designed for senior finance leaders. This is a hands-on role focused on building production-grade AI features end-to-end, from backend systems and agent architecture through to user-facing functionality. You’ll design and evolve multi-agent workflows, build AI-native capabilities such as GraphRAG and relational retrieval systems, and develop scalable services using TypeScript, NestJS, PostgreSQL, and GCP. Working closely with Product and Design, you’ll help turn complex financial workflows into intuitive user experiences while contributing to architectural decisions and raising the bar across the engineering team. The company’s mission is to transform finance from backward-looking reporting into real-time strategic intelligence using autonomous AI systems.

Tech stack: TypeScript, LangGraph, LLM Agents, NestJS, PostgreSQL, GCP, Docker, Pulumi, Graph Databases

Industry: B2B SaaS, AI, FinTech, Enterprise Software

This is an opportunity to join at an early stage with high ownership, real technical influence, and meaningful equity. You’ll work directly with experienced operators and a senior, low-ego engineering team, tackling genuinely hard problems where accuracy, reasoning, and reliability matter. The business is well-funded by leading investors and building a category-defining product in a large enterprise market, making this a strong fit for engineers who want impact, autonomy, and the chance to shape a frontier AI platform from the ground up.

To apply, please send your CV to Nathan Laidlaw at Transparent Technology via the application process. Applications are being reviewed on an ongoing basis.
