Chief of Staff (Senior-Role) f,m,d 100% – Zürich

Job Description

Chief of Staff (Senior-Role) f,m,d 100% – Zürich

Become part of a successful team and achieve success beyond your previous capabilities. Hungry for more? Properti is the leading and multi-award-winning PropTech broker in Switzerland. We combine highly trained experts with the latest technologies on an intelligent platform to provide customers, brokers and service partners with risk-free, flexible and simplified services.

What You Will Drive

Building growth

• You develop further new growth pillars and make them commercially viable: the franchise and licensing system to multiply properti across Europe, platform services, new monetisation models.
• You prepare market entries, internationalisation and execute them: business cases, market and competitive analyses, regulatory feasibility, go-to-market – you own it.
• You build strategic partnerships with a clear commercial goal: distribution and ecosystem alliances that open new channels and leads, and partnerships with banks and insurers for embedded financial and insurance products. You source and assess cooperation opportunities in collaboration with the CEO.
• You own pricing, business cases and the commercial feasibility of new services, markets, licensing models and products.

Making the business model scalable (AI-native)

• You evolve properti's business model: from people-driven brokerage to an AI-native, platform- and agent-based model that gets more efficient with every new market rather than more expensive.
• Together with our Lead AI Adoption & Strategy you identify which value-chain steps agentic systems can take over, build the business case for it and translate it into a roadmap.
• You make scalability measurable: unit economics, degree of automation and growth without linear headcount are your target metrics.

Turning strategy into results / project management

• You drive the CEO's most important strategic projects from idea to measurable outcome, with clear owners, timelines and numbers. You also pick up cross-functional projects that have no natural owner and bring them to a close.
• You keep the pulse on the business-critical KPIs, spot deviations early and, with the CEO's mandate, make sure the owners address them, with a clear definition of what needs to happen by when.
• You design and run the management cadence (leadership meetings, kpi-meetings quarterly reviews, board preparation) so decisions are made faster and with less CEO involvement.
• You deliver data-based decision inputs: KPIs, analyses and decision papers that let leadership decide better, and you translate strategy into executable quarterly plans in collaboration with the CEO-Office.
• You support the CFO and CEO on fundraising: preparing pitches, contributing to the equity story and investor strategy, and building investor materials.

How you operate

We are looking for someone driven by ownership, not by status. Your standing here comes from what you drive and deliver, not from a title or a team reporting to you. You take a problem, make it yours and push it all the way to execution, including against resistance and across team boundaries. You say what you think, even when it is uncomfortable, fairly and with respect. You hold high standards for yourself and for what you deliver. You are satisfied when things move forward, not when the meeting was pleasant.

Who You Are

• at least 5+ years at a top-tier consulting firm – McKinsey, BCG, Bain or equivalent – you know the difference between a slide and a result
• and 5+ years experience as real operator in a fast-paced growth environment / scale up
• Prior Strategy, Business Development, Growth or Chief of Staff experience is a strong plus
• Academic background from a leading university is a plus – what matters most is demonstrable impact
• You have owned a commercial outcome with measurable results – not supported it, not been part of the team – owned it with your name on the number
• You do not accept vague answers. When someone says "we are working on it", you ask what exactly, by when, and what happens if not. You follow up until it is closed – without apology, without being asked twice
• You have worked across multiple European markets and understand that scaling a model internationally is not the same as growing it locally
• IC-level role in a Series B-stage company with a clear path to IPO or similar
• German (a must) and English – both sharp in writing and in the room
• A team that moves fast, challenges each other, and wins together

What This Is Not

• A support function
• A comfortable next move
• A place to strategise without consequence

Timing:

February / March 2027

What You Get

• Direct access to the CEO and founders from day one, and full visibility into fundraising, expansion and strategic decisions.
• A stake in the outcome through our option plan. We want you to share in the upside when we win together.
• A real mandate with room to shape things at one of the most exciting PropTech scaleups in Europe.
• A clear career path: this role is a starting point, not an end station. Those who deliver move from here into a leadership role, for example leading international expansion or owning a growth pillar.
