THE OPPORTUNITY We are hiring a Staff Product Manager to help build our Occupational Health bet inside New Ventures based in Brazil . This is a Remote – Brazil position, meaning you can work from anywhere within the country. Please note that this role is only open to candidates in Brazil. Occupational health is one of the largest, most regulated, and most stubbornly analog corners of corporate wellbeing. In Brazil alone, it is a multi-billion real market: every company is legally required to run occupational exams, manage regulatory compliance (NR-01 and the new psychosocial-risk mandate, eSocial reporting), and look after the health of its workforce. Yet the industry still runs on paper, manual scheduling, fragmented clinics, and reports nobody reads. We intend to rebuild it, at AI speed. You will partner directly with the Founder/GM of the Occupational Health bet as the product lead of a small, single-threaded squad. This is a 0-to-1 build: the thesis is set, the market is chosen, but the product, the workflow, and the operating model are still being invented. You report to the VP Product, New Ventures, and you'll work daily with the Founder/G

About Eve Eve is redefining legal technology for plaintiff law firms, and we're building the team that will take us there. We help firms handle more cases, recover more for clients, and grow with AI that works across every stage of a case, from intake through resolution. The next generation of great plaintiff firms will be AI-Native, and Eve is how they get there. But what makes Eve different isn't just the product. It's how we build it. If you're someone who takes ownership, stays curious, and wants to build AI that's already changing how law is practiced, this is where you belong. Product-market fit: Eve is trusted by over 1000+ law firms, and we’re growing fast. Backed by top investors: We’ve raised over $160M from world-class partners including Spark Capital, Andreessen Horowitz(A16z), Menlo Ventures, and Lightspeed. Built by a world-class team: Engineers, designers, and operators from places like Scale, Meta, Airbnb, Cruise, Square, Rubrik, and Lyft are building Eve from the ground up. AI-Native from day one: We’re on the bleeding edge of AI, collaborating directly with teams at OpenAI and Anthropic to build best-in-class AI workflows tailored for legal work. Explosive growth: We are growing 2X revenue Quarter over Quarter. About the role 1,200+ law firms already run their practice on Eve. This role is about helping firms find and grow into the parts of Eve that matter most to them. You'll own growth and monetization design: trial-to-paid, usage-based pricing, upgrade moments. It's a role that sits close to the business side of the product, where design decisions directly shape revenue. We move fast, but never at the cost of building the wrong thing. We're high-autonomy and team-first — people who take initiative on their own, but still lean on the team, tend to do well here. What you'll do Shape how Eve's AI features get priced and packaged: usage tiers, seat/case limits, credits, premium features. Own growth design end to end: trial-to-pa

Everpure (NYSE: P) has evolved from storage pioneer to data platform, closing fiscal 2026 with $3.7 billion in revenue, its first billion-dollar quarter, and accelerating growth into FY27. Our strategic agenda spans the companies defining the next era of technology - hyperscalers, AI labs, the AI hardware supply chain, data platform providers, and the broader AI ecosystem. This type of work—work that changes the world—is what the tech industry was founded on. So, if you're ready to seize the endless opportunities and leave your mark, come join us. THE ROLE Everpure is moving from an application-centric world to a data-centric one — where AI depends on trusted, well-governed, and contextualized data across the business. As part of this shift, we're looking for a Staff Analyst, AI & Automation to lead the technical build of AI and applied ML capability inside the analytics function. This is an individual contributor role — you will not manage people. Your leverage comes from what you build and ship: AI agents, applied ML models, and automated analytics workflows that change how insight gets produced, working closely with cross-functional teams to bring these to life. AI is changing by the week, not by the year. We're not looking for someone who adopts AI once it's already mainstream — we want someone who is naturally ahead of the curve: scanning what's new, testing it quickly, and bringing it into the team before it's obvious to everyone else. This role has real freedom to experiment, rethink existing approaches, and change course as the field moves. WHAT YOU'LL DO Own the technical build of AI-powered analytics tools — including RAG pipelines, LLM-assisted querying, agent workflows, and applied ML models. Our current stack includes Glean, Gemini, Claude Code and Snowflake Cortex, and we expect that to change; we care more that you pick up new tools quickly than that you already know ours. Apply data science methods (forecasting, segmentation, anomaly detection, c
