Ultrassure | Toronto, Ontario | Remote considered for the right candidate
About Ultrassure
Ultrassure builds AI software for the insurance and reinsurance industry. Our platform helps underwriting teams turn complex submissions, contracts, endorsements, guidelines and claims documents into structured information and actionable insights.
We are a seed-stage company with more than $10 billion in premium represented on the platform and customers across Canada, the US, the UK, Bermuda and the Cayman Islands.
We are hiring a Full-Stack Software Engineer to help build the next generation of the platform.
The Role
You will work across frontend, backend, infrastructure and applied AI, taking ownership from the customer problem through architecture, implementation and production.
This role suits someone who enjoys building complete products, making practical technical decisions and seeing their work used by customers.
Our core stack includes Next.js, TypeScript, Python, Django and AWS.
We are based at Bay & King in downtown Toronto, with remote work considered for the right candidate.
What You Will Do
Build features end to end, from database models and APIs to intuitive user interfaces.
Develop production AI workflows using OpenAI, Anthropic and other model providers.
Build agents, tools, MCP integrations, structured outputs, retrieval systems and evaluations.
Improve document parsing, clause extraction, data enrichment, comparison and workflow automation.
Develop secure systems for authentication, role-based access, multitenancy and document processing.
Improve performance and reliability through queues, caching and better infrastructure.
Strengthen testing, observability, CI/CD and production security.
Work closely with the team to translate customer workflows into useful software.
Use Codex and other AI development tools effectively while maintaining strong engineering judgment.
What We Are Looking For
Strong software engineering fundamentals and the ability to work across the stack.
Experience with TypeScript and React or Next.js, alongside Python and backend API development.
Experience deploying and maintaining production applications in the cloud, ideally AWS.
Practical experience building LLM applications beyond basic chatbot demos.
Good product judgment and the ability to turn an ambiguous problem into a shipped feature.
Ownership, initiative and attention to security, reliability and maintainability.
Comfort working with messy documents and unstructured data.
Strong communication and the ability to collaborate effectively, whether in Toronto or remotely.
Eligibility to work in Canada.
We care about what you can build and how you think. Exceptional new graduates and experienced engineers are both welcome to apply.
