UnlikelyAI is a deep tech startup working to create a world where highly intelligent automated systems enable humanity to flourish and benefit us all. We are pioneering transformative technology aimed at making Artificial Intelligence more accurate, trustworthy and safe. We are combining the fantastic opportunities created using LLMs with the trust, accuracy and explainability of symbolic/algorithmic methods, which together we call our neurosymbolic platform. Based in London, we were founded by William Tunstall-Pedoe, best known for his role in creating Alexa after Amazon acquired his first startup.

We’re building a world where AI can be fully trusted; one that is reliable, accurate and transparent. Our neurosymbolic technology harnesses the power of LLMs and generative AI, and combines it with proprietary symbolic technology.
We’re working with companies like Lloyd’s Bank, major accountancy firms and insurers to solve problems that LLMs can’t: AI that is reliable and explainable.
At UnlikelyAI, we’re building on the frontier of research. Invention and speed are core to everything we do. The technology we develop has never existed before – and we’re looking for people excited by the difficulty of our mission.
The role We’re looking for a Junior Software Engineer, who is energised by difficult problems. Our software engineers work closely with research engineers and scientists to develop novel neurosymbolic solutions.
As a Junior Software Engineer, you’ll receive hands on mentoring and support from experienced engineers and managers, who will help you apply and develop your skills. We’re proud of our track record of helping early-career engineers become highly skilled senior engineers.
You’ll gain exposure to the full lifecycle of software engineering: Backend, Frontend and DevOps. You’ll also develop skills and expertise in working with AI research and machine learning.
At UnlikelyAI, you'll have the rare opportunity to work directly with our proprietary neurosymbolic technology – combining Large Language Models with symbolic reasoning in ways that haven't been done before. Unlike typical graduate roles where you might work on incremental features, here you'll be contributing to fundamental research problems: how do we make AI systems that can explain their reasoning? How do we ensure reliability when dealing with critical financial and regulatory decisions? You'll collaborate closely with our research team, gaining exposure to cutting-edge AI techniques whilst building production systems used by major institutions like Lloyd's Bank. This isn't about fine-tuning existing models; we’re inventing entirely new approaches to trustworthy AI.
