AI Systems - Senior Software Engineer

At the company, we’re on a mission to make Europe a powerhouse of entrepreneurship by building a modern, tech-driven equity management and financial reporting platform for private and public companies. In 2026, we aim to be the leading provider for European IPOs and reporting for share-based payments. We are a value-based company with a core focus on being humble, transparent, ambitious and impactful, all in order to deliver the best experience for our customers and end users.

About the Role

As a Software Engineer on our AI Systems team, you'll build the AI foundations and product experiences of the company: the company Agent, the tools and skills it runs on, our MCP server, and the platform capabilities that let other teams embed AI safely in their domains. You'll collaborate with fellow engineers, product managers, and designers in a new and fast-moving product area where correctness matters as much as speed - our customers need equity data they can trust.

Location: We hire remotely across the UK, Spain, Germany, Poland, and Romania. For candidates based in London, we use a hybrid model with 2 days in the office per week.

The team you’ll join: AI Systems - Develops the company's AI foundations and product experiences, from AI agents and AI-assisted workflows to the platform capabilities that help other teams embed AI safely in their domains. The team works in a new and evolving product area, balancing rapid iteration with reliable execution, evaluation tooling, and responsible automation.

What You'll Work On

• Help build the future of how companies manage equity.
• You’ll design and build the system behind our in-app agent, so equity administrators can do through AI what they do manually in the app today.
• You’ll shape the MCP server alongside the in-app agent, ensuring a capability built once works in both places.
• You’ll design and build the system we use to measure the agent’s quality and learn from how customers use it.
• You’ll design the foundations that let us build AI features once and reuse them everywhere.

You’ll own real parts of this and have a say in where we invest. You’ll also spend time with customers to see how administrators actually use the agent, and use that to decide what to build next.

You'll Thrive in This Role If You Don’t worry if you don’t tick every box. These are the things that would make you an especially good fit:

• You have 5+ years of experience working as a Software Engineer, with strong TypeScript/Node fundamentals across back end and front end.
• You’ve built and shipped agentic or LLM-based software to production.
• You’ve designed the agent itself: tools and skills, context and prompt engineering.
• You improve these systems with evidence.
• You keep up with what the foundation labs and the wider community are learning about building agents.
• You take part in deciding what we build.

Our Tech Stack

We work in a TypeScript monorepo: React and Tailwind on the front end, tRPC, Node.js, MongoDB, and Temporal on the back end. It runs on GCP with Kubernetes, managed through Terraform.
