Job description

About Allica Bank

Allica is the UK’s fastest growing company - and the fastest-growing financial technology (Fintech) firm ever. Our purpose is to help established SMEs, one of the last major underserved opportunities in Fintech.

Established SMEs are the backbone of local communities - representing over a third of our economy - yet have been largely neglected both by traditional high street banks and modern fintech providers.

Department Description

We’re building the next generation of intelligent financial tools for SMEs, starting with an AI-powered Treasurer. Our platform will give business owners real-time visibility across accounts, AI-native cashflow forecasting, and smart treasury optimisations — redefining how small and medium-sized businesses manage money.

Role Description

As our ML engineer, you will:

• Build and deploy ML and LLM-powered applications that deliver actionable financial insights and decision support.
• Work end-to-end across the stack: rapidly prototype and iterate with product and design to bring new features to life.
• Ensure models interpretability and explainability, so SMEs can understand the “why” behind the insights.
• Develop guardrails and fail-safes to guarantee AI outputs are trustworthy in high-stakes financial contexts.

Personal Attributes & Experience

• We strongly value talent, agency, curiosity, and hunger.
• Strong technical ability in machine learning, NLP, or large language models.
• Hands-on experience with Python, PyTorch/TensorFlow, and OpenAI SDK (or similar).
• Strong knowledge of Classification and Time series models.

Bonus points for:

• Experience shipping LLM applications in production.
• Contributions to ML/AI projects and/or a portfolio of ML projects you’ve worked on.
• Achievements in competitive programming, STEM olympiads, or other indicators of exceptional technical ability.
• Peer-reviewed publications.

Please note: This is a 12 month fixed term role with possibility to extend longer.
