Unlikely AI

ABOUT US At UnlikelyAI, we are building the future of AI: one that is reliable, accurate, and transparent. Our neurosymbolic technology harnesses the power of LLMs and generative AI, and combines it with Universal Language – our proprietary symbolic technology that bridges the gap between probabilistic machine learning and deterministic classical computing. Our products are already in use with major enterprises – including tier-1 banks and leading accountancy firms – across audit, compliance, and financial services. In compliance, we combine symbolic decision trees with LLM-powered evidence extraction to catch errors in financial reporting that human reviewers miss. In financial services, we use neurosymbolic guardrails to deliver accurate and explainable outcomes at scale. We are now building toward a platform – a public API and platform experience that will make our core neurosymbolic capabilities available to a broader set of customers and use cases. This is a pivotal moment: we're transitioning from bespoke customer engagements into a scalable product platform, and we need exceptional engineers to help us get there. THE ROLE To meet the demands of our growing commercial momentum, we are looking for a smart, dedicated senior software engineer to join our team. We want someone who thrives on diving deep into code to solve challenging and novel problems. You will have extensive software engineering experience, with exceptional coding ability, ideally including experience in high-growth start-ups. This role will play a major part in developing our core capabilities, which span symbolic reasoning (decision trees, propositional graphs, knowledge graphs), document ingestion pipelines, and the APIs that expose these to customers. You'll work on genuinely novel problems at the intersection of classical symbolic AI and modern LLMs – for example, how to represent regulatory knowledge as machine-evaluable rules, or how to build feedback loops that improve system accuracy over time. You'll work within a shared monorepo alongside software engineers, research engineers, and applied scientists in a heavily cross-functional environment. We operate in small, focused product teams, supported by shared infrastructure, internal tooling, and an R&D function. WHAT YOU MIGHT WORK ON In your first months, you could find yourself working on any of the following: * Building the infrastructure for our new public API, including authentication, scalability, and developer documentation. * Improving our document ingestion pipelines to handle new input formats (e.g. PDF, Word) and new regulatory jurisdictions. * Developing evaluation frameworks and benchmarks to measure and improve system accuracy. * Scaling our deployment approach for enterprise customers with specific cloud and security requirements. * Improving internal tooling and developer experience across the monorepo. * Working on the symbolic reasoning engine that powers our products – including decision tree evaluation, rule generation, and knowledge graph construction. YOU'LL BE SUCCESSFUL HERE IF... * ...you have strong proficiency in Python, including writing well-typed, well-tested code in a collaborative codebase. * ...you've tackled complex algorithms and data structures and have experience working with non-trivial algorithmic problems. * ...you care deeply about production-quality engineering – you have a track record of advocating for software quality, improving engineering standards, and championing best practices. * ...you thrive with end-to-end ownership – you've led the process from ideation to production for brand-new software systems. * ...you have experience with cloud infrastructure (AWS preferred) – services such as S3, ECR, ECS/EKS, and infrastructure managed via Terraform or similar. * ...you have a bias for action – you move quickly, make informed decisions, and iterate without waiting for perfect information. * ...you have a relevant degree in Computer Science, Mathematics, Engineering, or STEM – or equivalent practical experience. OTHER SKILLS You don't need to tick every box below, but any of the following would strengthen your application: * Monorepo experience – comfortable working in a large, shared codebase with multiple product teams contributing. * CI/CD pipelines – hands-on experience with GitHub Actions or similar. * Experience with document processing pipelines – PDF parsing, OCR, structured data extraction. * Familiarity with knowledge representation – decision trees, knowledge graphs, ontologies, or symbolic reasoning systems. * Experience with LLM integration in production systems – prompt engineering, evaluation, working with APIs such as Gemini, Claude, or OpenAI. * Frontend experience with React and TypeScript – we value engineers who can contribute across the stack when needed. * Experience in regulated industries – fintech, audit, compliance, insurance, or banking. * Familiarity with the modern Python tooling ecosystem: uv for package management, ruff for linting, pyright or similar type checkers. * Experience with observability and monitoring tools such as Datadog. HOW WE WORK We're a team of around 30 people based primarily in the UK. We operate a hybrid working policy, with three days a week in our Central London office. Engineering is organised into product-focused squads, supported by shared infrastructure and an R&D function. We work in a monorepo, deploy to AWS, and care deeply about developer experience – we're actively investing in modernising our tooling, CI, and repository structure. We run hackathons, we have strong opinions about code quality (held loosely), and we ship often. Our culture is collaborative and low-ego: engineers regularly move between teams, pair on hard problems, and contribute ideas regardless of seniority. We take the work seriously, but not ourselves. INCLUSION AND EQUAL OPPORTUNITIES We are committed to having a truly diverse team where everyone is encouraged to be their authentic selves. We are an equal opportunity employer and do not discriminate based on gender, race, religion, sexual orientation, national origin, political affiliation, disability, age, marital status, medical history, parental status or genetic information. We are committed to fostering an inclusive environment where everyone feels respected, supported, and able to thrive.

THE ROLE We are looking for a Staff Software Engineer to help shape the technical direction of our platform as we scale. This is a role for someone who combines deep hands-on engineering ability with the judgement and influence to drive architecture and engineering quality across teams. You'll be one of our most experienced individual contributors – someone the team looks to for guidance on hard technical decisions, system design, and long-term technical strategy. You'll spend most of your time writing code and solving complex problems, but you'll also be expected to identify the highest-leverage work across squads, mentor other engineers, and raise the bar for how we build software.
