About Us At UnlikelyAI, we are building the future of AI: one that is reliable, explainable, and resistant to hallucination. Our patented neurosymbolic platform combines the expressive power of LLMs with the transparency and control of symbolic reasoning. This enables us to create AI systems that are accurate, auditable, and suitable for high-trust, high-stakes applications - where precision, traceability, and compliance are essential. The Role We're looking for a Senior Software Engineer to be the Tech Lead for Uncheck, our accounting disclosure product, and lead its planning and delivery as it scales across customers and markets. You'll own the technical plan and sequencing, working with product and customers, and make sure it is delivered well and on time, while staying hands-on in the code. Uncheck automates the checking of accounting disclosures. It reviews financial statements against the accounting standards and regulations that apply to them, and shows the evidence behind each finding. It is live in production at enterprise scale, and we are expanding it into new regions and markets. This role is ideal for someone who enjoys leading the delivery of software as much as build
