At Joko, we help consumers shop smarter. Our mission is to revolutionize shopping, empowering people to find what they need, make
informed decisions, and save money.
Founded in Paris, Joko is a tech company and certified B Corp with over 105 talents across Paris, Barcelona, and New York (and
beyond). More than 6 million users already save money every day at 10,000+ merchants with Joko.
From cashback and automatic coupons to price alerts and carbon tracking, we keep expanding our products to make shopping smarter.
We’re now building an AI-powered shopping assistant to help users find the best products by price, quality, and environmental
impact.
Having reached profitability in our core market, we’re now scaling globally, with a strong focus on the US.
It’s still day 1, come build the future of shopping with us!
This position is based in Paris.
The CEO Office is a hands-on team of high-potential generalists who lead Joko's strategic projects and, when needed, step in to
reinforce teams on short to medium deployments. You'll take over a team of five Founder Associates, with room to grow as the
company scales.
As the leader of that team, your job is to build a team people are proud to be part of, where every Founder Associate grows
quickly and contributes meaningfully to Joko’s most important priorities.
You'll be the CEO's strategic partner at a specific, rare moment in a company's life: a profitable scale-up entering its
international chapter, expanding new business lines, doubling in headcount over the next 18 months, and investing heavily in AI —
with a mature leadership team, a culture worth protecting, and a team that demands excellence.
You'll report directly to Xavier (CEO), partner closely with co-founders Nicolas (CRO) and Alexandre (CTO), and serve as secretary
of the Steering Committee, which is composed of the founders, the CMO, the COO, the VP People, and the Head of Online — putting
you at the heart of every strategic decision the company makes.
The Chief of Staff role is built around the CEO, and the CEO Office is in turn built around the Chief of Staff — together, the
team exists to act as an extension of the CEO. The mandate is fourfold today, and you'll be the architect of all four pillars (as
well as the future ones).
1. Governance. Your team and you will own the rhythm and quality of how Joko is run at the top — board meetings, executive team
meetings, All Hands, and the communication cadence that ties them together. You'll play a central role as animator and
alignment driver for the leadership team.
2. Proactive projects. Your team and you will lead the company-wide initiatives that matter most to the CEO and to Joko's next
chapter — the kind of cross-functional, high-stakes work that doesn't naturally fit any single team.
3. Reactive missions. When a team needs short-term reinforcement, you'll deploy Founder Associates as a strike force, helping us
address critical gaps without hiring in a rush. This will represent a decreasing share of the team's activity as the
organization grows.
4. Culture. Like every member of the SteerCo — and like the CEO — you'll be expected to embody Joko's culture and lead by
example.
A word from Xavier
"This is one of the most consequential hires I'll make this year. I'm looking for a real partner — someone with the rigor to
challenge my thinking, the architectural mind to build durable systems, and the warmth to carry our culture as we scale. The Chief
of Staff is, in many ways, an extension of me, and the right person will shape Joko's next chapter alongside Alex, Nico, and me."

ABOUT VOODOO Founded in 2013, Voodoo is a tech company that creates mobile games and apps with a mission to entertain the world. Gathering 1,000 employees, 7 billion downloads, $1b+ revenues and over 200 million active users, Voodoo is the #3 mobile publisher worldwide in terms of downloads after Google and Meta. Our portfolio includes chart-topping games like Mob Control and Block Jam, alongside popular apps such as BeReal and Wizz. ROLE You will work directly with Voodoo's CEO as a force multiplier on the company's highest-stakes topics. This is an operating role, not a support role: you own outcomes on strategic projects, incubate new ventures, keep the company's operating rhythm sharp, and lead a small team of Special Project Managers who act as Voodoo's internal consulting force. WHAT YOU WILL DO * Run strategic projects with the CEO — frame the problem, drive the analysis, align leaders, and push to execution on topics spanning M&A, market expansion, monetization, and organization. * Explore and launch new ventures — assess opportunities beyond the current portfolio, build the business case, assemble a founding team, and get v1 to market. * Manage company routines — own the operating cadence: leadership meetings, business reviews, OKR/goal cycles, board preparation; make sure decisions get made and followed through. * Drive the SPM team — recruit, staff, and coach a team of internal consultants deployed on the company's most pressing operational problems; own prioritization of their portfolio. * Be the CEO's proxy — represent him in meetings, unblock cross-functional issues, and surface what he needs to know before it becomes urgent. WHAT WE'RE LOOKING FOR * 6–10 years of experience combining top-tier strategy consulting (Engagement Manager / Project Leader level at MBB), or M&A/PE, and operating experience in a hypergrowth tech company (BizOps, strategy, GM, or founder). * Track record of leading cross-functional projects at C-level with measurable business impact. * Entrepreneurial: has built something from scratch (venture, business line, market launch). * Strong analytical and financial fluency — comfortable with a P&L, unit economics, and data. * Exceptional communication: crisp, top-down, comfortable challenging senior leaders. * Low ego, absolute discretion, and stamina for a fast pace; obsessive about follow-through. * Top-tier academic background * Fluent English (French is a plus); Gaming/consumer-app affinity a plus. WHAT WE OFFER * Daily exposure to the CEO and leadership of the world's #3 mobile publisher. * A launchpad role: previous holders of comparable seats typically move into GM/VP/founder roles. * Competitive package. BENEFITS * Swile Lunch voucher * Gymlib (100% borne by Voodoo) * Premium healthcare coverage SideCare, for your family 100% borne by Voodoo * Wellness activities in our Paris office

Qui sommes-nous ? Sweetch, c'est la nouvelle aventure née de la reprise des actifs de ZeWay par Heetch en avril 2025. Notre mission : (re)lancer et opérer un réseau de bornes d'échange de batteries pour scooters électriques en région parisienne, tout en commercialisant les scooters qui vont avec. Concrètement, le principe est simple et malin : les batteries sont amovibles. Une fois vide, le rider se rend à une de nos bornes, échange sa batterie à plat contre une chargée, et repart. Pas d'attente, pas de compromis. On repart de zéro — et c'est exactement ce qui rend le moment unique. Tu rejoins une petite équipe en train de construire quelque chose, avec un vrai impact sur chaque décision prise. Si tu veux apprendre en faisant, tu es au bon endroit. Tes missions Chez Sweetch, l'opérationnel ne manque pas. Tu auras la main sur quatre grands axes : 1. Vendre notre stock de scooters Identifier et activer de nouveaux canaux d'acquisition clients Améliorer et fluidifier la procédure de vente de bout en bout Travailler main dans la main avec les commerciaux pour les aider à atteindre leurs objectifs 2. Faire tourner notre réseau de bornes de recharge Analyser la performance du réseau et proposer des initiatives concrètes pour l'améliorer Mettre en place les procédures de maintenance préventive Optimiser les interventions lorsqu'une borne est bloquée — chaque minute d'indisponibilité compte 3. Gérer les abonnements et le recouvrement Suivre les paiements des abonnements batteries et assurer la bonne santé du portefeuille clients Piloter la communication client pour augmenter le nombre d'abonnés actifs et limiter le churn Mettre en place et optimiser les processus de relance afin d'améliorer le taux de recouvrement Identifier les leviers pour fidéliser les clients et allonger leur durée de vie 4.
