Multiverse is the upskilling platform for AI and Tech adoption. We have partnered with 1,500+ companies to deliver a new kind of learning that's transforming today’s workforce. Our upskilling apprenticeships are designed for people of any age and career stage to build critical AI, data, and tech skills. Our learners have driven $2bn+ ROI for their employers, using the skills they’ve learned to improve productivity and measurable performance. In April 2026, we announced $70 million in strategic funding, led by Schroders Capital, with participation from StepStone Group, Lightspeed Venture Partners and General Catalyst. At an increased valuation of $2.1bn, the round makes us Europe’s first EdTech double unicorn. But we aren’t stopping there. With a strong operational footprint and 800+ employees, we have ambitious plans to continue scaling. We’re building a world where tech skills unlock people’s potential and output. Join Multiverse and power our mission to equip the workforce to win in the AI era. About the role Billions have gone into enterprise AI. Most of it isn't working — organisations still can't turn model capability into measurable business impact. That's not a training problem or a slide-deck problem. It's a hard, unsolved technical challenge: building the systems that translate what AI can do into how work actually gets done inside real organisations, at scale, with proof it's working. That's the problem Multiverse exists to solve, and it's the one this role exists to sell. We're hiring a Senior Leader of Product Marketing, reporting to the CPTO, to own the positioning, competitive intelligence, and go-to-market orchestration that makes that story credible to buyers who've heard "AI transformation" pitches before and have learned to discount them. This is a strategic leadership and launch-execution role: you're accountable for a narrative that has to survive a skeptical CTO's follow-up questions, not just land in a pitch deck. You'll sit at the center of Pr

Our Product Management team drives product initiatives from inception through execution, makes impacts and launches products/features across our global footprint. We collaborate closely with engineers, designers, analysts, marketers, and other cross-functional team members to ship remarkable features and products. Role Overview We are looking for a Senior Product Manager to own customer onboarding across the Crypto.com App and adjacent product surfaces. Onboarding is where regulatory requirements, customer acquisition, and time-to-first-value meet. Every improvement you ship should help more customers open an account compliantly, activate faster, and reach the products that matter. Your mandate is to own the onboarding journey as both a growth product and a regulated platform: KYC and account opening, activation and referral mechanics, new-product onboarding, and a meaningful trading scope. Within six months, you will own the onboarding-and-growth charter and take on trading product work in addition to the onboarding charter. You will report to Onboarding squad Lead and work closely on the trading portion of the charter. You will run your roadmap with independence, make prioritization calls, and own the how and the when. If you have built onboarding in a regulated consumer fintech, parts of this will feel familiar. The difference is the breadth: one onboarding platform must support a growing set of products, regulatory paths, and trading journeys. The playbook is still being written. What You'll Actually Do: Own compliant customer onboarding end-to-end. You set the roadmap for account opening, identity verification, KYC requirements, and platform capabilities. You make the tradeoffs between conversion, speed, risk, and regulatory obligations. Turn onboarding into a growth engine. You own activation, referral, new-user incentives, and time-to-first-value.
