Chief Of Staff (COS)
Storm4 has built a trusted portfolio of Chief of Staff (COS) leaders who operate at the centre of Clean Energy, Infrastructure, and Mobility businesses. These are operators who keep leadership teams focused, aligned, and moving fast.
Whether you’re expanding your executive team with a Chief of Staff, or you’re a COS looking for your next move in a scaling CleanTech organisation, Storm4 brings both sides together.
What Is A Chief of Staff?
The Chief of Staff (COS) is a senior strategic partner to the CEO and executive team, responsible for enabling effective decision-making, streamlining operations, and ensuring that organizational priorities move forward.
The role sits at the intersection of strategy, operations, communication, and leadership, making it one of the most versatile and highly trusted positions within a scaling CleanTech company.
In industries such as renewable energy, electric mobility, and sustainable infrastructure – where businesses often scale quickly, enter new markets, and navigate complex regulatory environments – the COS ensures that leadership stays aligned, informed, and prepared. They help turn the CEO’s vision into actionable plans, anticipate challenges, and act as an internal bridge across the entire organization.
A successful COS balances discretion, diplomacy, analytical thinking, and project management, becoming an extension of the CEO and a critical driver of organizational clarity and momentum.
Key Marketing Director responsibilities include:
- Being a sounding board for the CEO and other senior executives
- Representing the CEO at meetings and events they are unable to attend themselves
- Assisting executives with their tasks, such as decision-making, project management and business strategies
- Collaborating with and advising the CEO
- Assisting in the implementation of strategies
- Act as a liaison between executives and other relevant parties
- Assisting human resources with the hiring of new employees and overseeing their onboarding process
- Identifying goals and objectives

Chief of Staff Salary Expectations
Chiefs of Staff command competitive compensation packages reflecting the strategic importance of their role and their proximity to the CEO. Compensation typically includes base salary, performance bonuses, and in some cases equity, especially in high-growth or VC-backed CleanTech companies.
This importance is reflected in compensation, with an average Chief of Staff (5-7 years experience) expecting a base salary in the region of $150,000 – $180,000. Though some more experienced Chiefs of Staff may have higher expectations depending on the stage of an organization.
