Chief of Staff - Optexity

ABOUT OPTEXITY Optexity is a product-driven research lab building clinical reasoning and computer use models on data no other lab can reach. We deploy directly inside clinics and hospitals — including systems with no APIs, using integration infrastructure we've built and open-sourced — and in return become their preferred partner. That gives us proprietary clinical reasoning trajectories from practicing physicians, and a feedback loop between real patient encounters, our models, and the products built on top of them. We're a small, fast-moving founding team with multiple published papers in NeurIPS, ICML, CVPR etc and background from Apple, Amazon, Microsoft, CMU, IIT. We are backed by world-class investors and leaders like Jeff Dean, Neotribe VC, PearVC, Together Fund and Zapier Fund. HOW WE WORK - Customer obsession — we start with the customer and work backwards - Intellectual honesty — ideas matter more than titles; we communicate directly and assume good intent, even in disagreement - Bias for action — we build and learn with customers rather than debate in the abstract - Extreme ownership — we own outcomes, not just tasks, and see problems through About the role This is not an EA role, and not a strategy role — it's a hands-on generalist operator who owns the business, legal, and people infrastructure that lets a small team move fast without breaking. You'll be the person who makes sure the company runs: contracts get signed, people get paid, compliance holds up, and nothing critical falls through the cracks. You'll work directly with the founders and build the operational backbone from close to zero. Why this role exists Legal, HR, accounting, payroll, compliance, and day-to-day operations all sit on the founders' plates today, alongside product and engineering. In a healthcare company, this surface area is heavier than usual — BAAs, HIPAA and state privacy obligations, and customer contracts can't be an afterthought. We need one person to own all of it end to end: not just execute tasks, but build the systems, vendor relationships, and processes so these functions run reliably as we scale. What you'll do - Legal & contracts — manage outside counsel, own the contract lifecycle (customer agreements, BAAs, NDAs, vendor and consulting agreements), and keep corporate housekeeping in order: cap table administration, board and investor documents, entity and state registrations - Compliance — own the operational side of HIPAA and state privacy compliance, coordinate audits and security certifications (e.g. SOC 2) as they come up, and maintain the policies, records, and vendor due-diligence that customers and regulators expect - HR & people ops — run onboarding/offboarding, offer letters, benefits and PEO administration, immigration/visa support for the team, and keep employee policies and records clean and current - Accounting & payroll — own bookkeeping oversight with our accountants, run payroll and contractor payments, manage AP/AR, expenses, banking, and the monthly close - Everyday operations — manage vendors, software and tooling, insurance, and the logistics of a fast-growing team; be the default owner for the operational thing no one else is holding - Founder leverage — take ambiguous operational problems off the founders' plates, structure them, and drive them to done What we look for - A generalist who's comfortable owning many unrelated functions at once and context-switching cleanly between them - Strong execution and follow-through — you close loops and things don't slip - Highly organized and detail-oriented, with good judgment about what's genuinely important vs. merely urgent - Operates in ambiguity and builds process where none exists, without waiting for perfect instructions - Trustworthy with sensitive legal, financial, and personnel information - Willing to do unglamorous, high-value work - Fast learner with genuine interest in the operational and regulatory side of a healthcare company Nice to have - Prior
