About Ema Ema is building the world’s leading Agentic AI platform to transform enterprise productivity. We enable organizations to delegate repetitive tasks to Ema, the Universal AI Employee, delivering 10x gains in workforce efficiency, across functions. Founded by former executives from Google, Coinbase, Flipkart, and Okta, our team includes engineers from premier tech companies and graduates of Stanford, MIT, UC Berkeley, CMU, and IITs. We are backed by industry leading investors including Accel, Naspers/Prosus, Section32, and angels like Sheryl Sandberg and Dustin Moskovitz. Headquartered in Silicon Valley and with offices in London, Bangalore and Vancouver, Ema is at the frontier of what Agentic AI can do in production — we ship real systems that run real business processes at scale. Role Overview As Chief of Staff to the CEO, you will be the strategic nerve center of the entire company — a true force-multiplier to Surojit Chatterjee (ex CPO Coinbase, VP Products at Google). Reporting directly to the CEO and based in Mountain View, CA (full co-location required), you will own the translation of the CEO's vision across Sales, Product, and the full organizational agenda — serving as connective tissue between the CEO and every critical function: EPD, GTM, Finance, HR, Legal, and the Board. This is a senior operating role for someone who has already done it — led strategy at scale, driven GTM at a high-growth technology company, and earned their stripes as an Engagement Manager or Associate Principal at a top-tier consulting firm (McKinsey, BCG, Bain) before stepping into industry. You are not here to learn the ropes; you are here to pull them. Ema is backed by top-tier investors (Accel, Section 32, and Prosus) and is building the Universal AI Employee for enterprises worldwide.

Secure Every Identity, from AI to Human Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence. This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk. The Role You'll join the team designing Okta for AI Agents — one of Okta's newest and most critical strategic initiatives, providing identity management, access control, and governance for AI agents and non-human identities. Our customers are IT and security admins, AI developers, and system architects who need to safely deploy and govern how AI agents interact with corporate data, tools, and production environments. As a designer on this team, you'll own key workflows end-to-end, from early-stage concepting of novel interaction models (there's no established pattern library for "agentic permissioning" yet) to hardening flows for scale as the product matures. You'll partner closely with product managers, engineers, researchers, and content designers, and work closely with our Principal and Staff designers, to turn ambiguous, highly technical agentic problems such as delegation, policy, audit, and trust boundaries between humans and agents into experiences that feel simple and safe. You'll be expected to bring sound design judgment to problems that don't have precedent to borrow from, and to actively experiment with how AI can be woven into your own design process, from exploration to prototyping. What you will do Own key workflows end-to-end, from early-stage concepting of novel interaction models, where few established patterns exist yet, through hardening and polishing flows as the product matures and scales to millions of customers. Bring a systems-think

This is a unique opportunity to architect a foundational system that will power data across our products and business, supporting everything from real-time analytics to AI/ML initiatives.

You'll lead from the front, writing production-grade code, setting high standards for design and data governance, and mentoring a team of engineers as the organization grows.

We believe that our work is instrumental to the widespread adoption of AI and we are looking for folks that want to be part of that. We obsess over what we build. Each one of us is responsible for contributing to increasing the capabilities of our models and the value they drive for our customers. Cohere is a team of researchers, engineers, designers, and more, who are all passionate about their craft.

By combining AI, human expertise, personal health data, and accountability, Future helps members improve performance today while building the resilience, capacity, and healthspan they need for decades to come. ABOUT THE ROLE: We’re hiring a Staff Product Manager to own the core marketplace experience. We’re rethinking things from the ground up—you won’t be inheriting a roadmap, a backlog, or a set of conventions. You’ll be building the product from the ground up alongside the CPTO. This role requires someone who thinks in systems. A marketplace is not a single product—it’s an ecosystem. You’ll need to hold the consumer experience, the practitioner experience, the matching logic, the trust and safety layer, the business model, and the growth loops in your head simultaneously, and make smart tradeoffs between them every day. You will report directly to the CPTO and work alongside a small, senior engineering team. There are no layers between you and the work, and no layers between you and the decisions that shape the company. WHAT YOU’LL OWN: Product Strategy & Vision Define the product vision and strategy for the marketplace, grounded in deep user understanding, competitive analysis, and a clear-eyed view of the business model. Own the roadmap end-to-end. Decide what to build, what to kill, and what to sequence—with conviction, not consensus. Develop and maintain a strong point of view on where the wellness and longevity market is heading and how our product should evolve to lead, not follow. TRUE 0→1 product thinking: identify the fastest and cheapest ways to validate core assumptions before committing significant engineering investment. Marketplace Systems Thinking Design and optimize both sides of the marketplace: the cons
