Chief of Staff (Hamburg)

As OceanScore’s Chief of Staff, you are the operational backbone to our MDs and a key member of the management team. You bring structure, focus, and follow-through to our fast-growing organization. Your mission is to turn priorities into execution — connecting strategy, operations, and people. You oversee internal governance, drive cross-functional alignment, and ensure that projects and decisions move from idea to impact.

This role sits at the intersection of strategy, internal operations, and communication, shaping how OceanScore grows and scales sustainably.

Your Key Responsibilities

• Operational governance: Design and maintain our internal operating model to drive organisational maturity; including management meetings, meeting cadences, OKR cycles, and reporting frameworks.
• Financial coordination: Ensure data-driven decision-making by structuring reporting processes, preparing shareholder and board updates, in collaboration with Finance as well as supporting preparations for future financing round(s).
• Confidential liaison: Act as a trusted sparring partner to the Managing Directors and management team, providing critical input, ensuring follow-through on decisions, and maintaining discretion on sensitive matters.
• Internal Project management: Lead special company-wide, cross functional projects such as ISO certification, implementing new tools or systems in cooperation with expert teams, or other strategic transformation projects.
• Cross-functional coordination & communication: Strengthen information flow and collaboration across teams by owning and proactively optimizing the tech stack that supports efficient cross-departmental work.

What You Bring

• Experience in a fast-paced, international start-up or scale-up, ideally in a commercial, operations, or strategy role.
• A structured and analytical mindset to turn complexity into clarity.
• Strong financial literacy and comfort with data, reporting, and decision support.
• Demonstrated success in establishing scalable structures and frameworks (e.g., OKRs, operating models, or company cadences).
• Excellent project management skills and experience being a thought leader on cross-functional initiatives.
• Proficiency in English; German a plus.

How You Work

• You thrive in a dynamic, evolving startup environment and see change as part of progress.
• You communicate clearly and in a structured way.
• You take initiative and are hands-on, building structure as we scale.
• You enjoy working closely with an international crew, both in person and across time zones.
• You are pragmatic: Good structure matters and you get things done.

Success in This Role Will Be Measured By

• Process Maturity: Well established meeting cadences, effective meetings and clear ownership of OKR cycles. State of the art internal and external reporting.
• Strategic Execution: Successful delivery of cross-functional projects (ISO, IT, etc.) against agreed objectives, timelines and budgets.
• Enhanced organisational alignment: Improved follow-through of key decisions and initiatives.
