Senior Software / AI Engineer

London (Hybrid - 2 days/week) Permanent

What We're Building

AI in finance has reached an inflection point. Models can analyse markets with superhuman speed-but they stop short of taking responsibility. We re building the company that closes that gap.

Eunice is a vertical AI platform for alternative assets. We started with digital assets (working with Coinbase, Copper.co) and are now expanding into private markets. We don't just deliver analysis - we deliver decisions institutions can defend: traceable, evidence-backed, accountable.

Backed by $8M from Moonfire, Speedinvest, Openspace Capital, and Locus Ventures. Named to Sifted's 2026 Top 100 fastest-growing UK startups.

In five years, every financial institution will run on agents that don't just analyse, but act with accountability. If that excites you, come build it with us.

The Role

We re hiring aSoftware / AI Engineerto help architect and ship the AI systems powering all Eunice product lines. This isnót a "thin AI wrapper" role-we re rebuilding financial decision-making infrastructure from first principles.

Yùour work across the stack (backend/frontend/data/AI), initially focusing on 1-2 areas where youùre strongest, with the goal of developing versatility across all domains. We believe in elite individual contributors with AI leverage - engineers who own big pieces of the system, ship fast, and obsess over quality.

What You ll Do

Design and implement core components of Eunice's proprietary AI system

Own end-to-end delivery: build, test, deploy, and maintain key features or entire product lines

Rapidly prototype new capabilities while maintaining production-grade quality standards

Participate in architecture reviews, retrospectives, and product strategy discussions

Contribute across domains: application layer (frontend/backend), data pipelines, or AI infrastructure

You ll Thrive Here If You Have Must-haves:

• 5+ years of software engineering experience with strong computer science fundamentals
• Deep expertise in at least one language (Python, TypeScript/Node, Go preferred) and comfort learning others
• System design proficiency - you enjoy architecting scalable, robust systems and thinking through trade-offs
• Quality obsession - you ship fast but never settle for brittle code; you build for extensibility and scale
• Ownership mentality - you re comfortable with ambiguity, comfortable making calls, and comfortable being accountable for outcomes
• Versatility - you re backend-strong but willing to touch frontend, data, or AI when the problem demands it
• Experience building systems around crypto/blockchain data
• Experience with AI-native architectures (agents, LLM orchestration, evaluation pipelines)
