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.

We’re looking for a Machine Learning Engineer to join us at the ground floor. Whether you’re an experienced ML engineer who has shipped LLM-powered products or a graduate with exceptional technical talent ready to make a real-world impact, this is an opportunity to help shape the future of AI native financial services.

We're a small team (two people + you) and we're moving very quickly!

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: from prompt design and fine-tuning models, to architecting scalable inference infrastructure and designing evaluation frameworks.

• Rapidly prototype and iterate with product and design to bring new AI-native features to life.

• Ensure enterprise-grade reliability and low latency in real-world, high-stakes financial settings.

• Play a central role in shaping our engineering culture, technical direction, and AI stack.

Personal Attributes & Experience

• We’re open to both seasoned ML engineers and standout graduates — what matters is talent, drive, and a hunger to build at the frontier of AI.

• Strong technical ability in machine learning, NLP, or large language models.

• Hands-on experience with Python, PyTorch/TensorFlow, Hugging Face, LangChain, or similar frameworks.

• Build robust evaluation frameworks to assess model performance beyond accuracy — focusing on explainability, fairness, and financial reliability.

• Develop guardrails and fail-safes to ensure AI outputs are trustworthy in high-stakes financial contexts.

• Work on model interpretability and explainability, making sure SMEs can understand the “why” behind the insights.

• High agency, ownership and curiosity: comfortable working in ambiguous, fast-moving environments.

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.
