About Katapult Labs
Katapult Labs is an innovative legal technology firm, currently in stealth mode, that leverages AI to transform plaintiff-side litigation at an institutional level. Our mission is to redefine the legal profession through cutting-edge technology that builds essential infrastructure in a field that is ripe for innovation. Following a highly successful seed funding round in February 2026, we are on the lookout for talented individuals to help shape our future.
We pride ourselves on a focused engineering culture that values precision and impact. This is not a typical environment where tasks are assigned and feedback is awaited; rather, we seek individuals who thrive in high-stakes situations and who think systemically about their work.
The Role
We are searching for a Founding Builder to join our core team. This is not merely a job opening; it is an opportunity for a top-tier engineer to contribute to something of significant importance. You will take ownership of backend architecture and will be responsible for designing elegant, user-friendly systems while collaborating with product-oriented teammates. Your work will directly involve AI systems, including LLM orchestration and agentic workflows.
Given the regulated nature of our domain, experience in legal tech, compliance-related data pipelines, or enterprise SaaS is highly advantageous. You understand the stakes involved and are committed to building systems that mitigate risks associated with incorrect outputs.
Qualifications
You possess deep expertise in software engineering with a backend-first approach. You are capable of independently managing complex platforms and have successfully delivered production-grade systems. Your experience includes designing infrastructure for AI applications, where you have integrated LLMs as foundational elements rather than mere features.
Operating autonomously with minimal oversight, you communicate effectively, identify obstacles early, and adapt to fast-paced environments. Your background includes working in sectors where precision is critical, such as legal, compliance, healthcare, or fintech.
