Machine Learning Engineer

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.

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!

• 
  
• 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.
  

• 
  
• 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.
  

• 
  
• 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.
  

This is a 12 month fixed term role.
