Founding Engineer
Clusia
About the job Clusia is led by Reed Switzer, founder of Hopscotch, a B2B payments startup acquired by Avalara / Vista Equity Partners, and Nolan Hendrickson, who previously led engineering teams within Microsoft's Defender organization. The company is venture-backed and has not yet been publicly announced. Company Description The next great compliance firm will be a software company. We're building it. Compliance is one of the largest opportunities hiding in plain sight. There are 500,000+ compliance officers in the U.S. representing $40B+ in annual labor spend - and companies spend billions more on audits, consultants, and outsourced reviews. Every dollar of it is required. And nearly all of it is still delivered the way it was thirty years ago: scattered systems, spreadsheets, email threads, and manual follow-up. We deliver that work differently. Software drafts it from the customer's own data, with every answer cited to its source - and accredited professionals review, decide, and sign. Our ambition is to become the AI-native compliance firm. Role Description We're beginning to build out the founding team and are looking for a small number of founding engineers to work closely with the CTO from zero to one. This will not be a big team. We plan to stay lean, with high talent density, no layers, and no fluff. As a founding engineer, you'll own important parts of the product and company from the beginning -- from core architecture and infrastructure to customer-facing workflows and AI-powered product experiences. You won't be handed a neatly scoped ticket queue. You'll be expected to understand customer problems deeply, make good technical decisions in ambiguity, and build systems that can earn trust in a highly regulated environment. Note: This role is in-person in New York City and you are required to ship code. Why Join Compliance tech is next up. We believe compliance is entering the same kind of transformation legal tech has seen over the last two years: large, high-stakes workflows being rebuilt around AI, collaboration, and better systems of record. We're building a small, high-talent-density team. Clusia will remain lean by design. There will be few openings and the bar for talent is incredibly high. Your work will matter at global scale. The systems we're building will power critical operations for some of the largest financial institutions and technology companies in the world. You'll work with founders who have done this before. The founding team has built and sold venture-backed companies in the past and is applying those lessons to build Clusia with focus, urgency, and ambition. Qualifications AI expertise: You have hands-on experience with LLMs, agents, retrieval, prompting, and production AI systems. Full-stack product engineering: You can build clean, reliable product experiences end to end. Infrastructure depth: You're comfortable with cloud services, deployment, observability, reliability, and security. AI evaluation experience: You know how to design tests, benchmarks, and feedback loops to measure model and agent quality. Startup execution mindset: You're pragmatic, fast-moving, product-minded, and comfortable owning ambiguous technical problems. Empathy for users: You care deeply about the people using what you build, not just the technical elegance of the solution. Builder energy: You've built things outside of work -- maybe a Minecraft server as a kid, a side project, a tool for your friends, a company, an open-source project, or something nobody asked you to build. #J-18808-Ljbffr Clusia
