🧭 About Us

We’re a remote-first, mission-driven, registered non-profit, comprising around 50 highly-skilled and motivated professionals from all around the world! Our culture is built on trust, autonomy, and collaborative professionalism.

We thrive in a fast-paced, distributed environment, where communication is clear, empathy is second nature, and each of us takes full ownership of our work. We work independently, but also collaborate easily when appropriate.

Open Energy Transition (OET) is a non-profit organisation advancing the global energy transition by developing innovative open-source tools and data solutions for energy and grid planning.

Our vision is to make open approaches the global standard by 2030, enabling energy planning that is more accessible, transparent, and effective. This shift is essential to better guide trillion dollar worth public and private investment toward affordable, sustainable, and secure energy systems. This is not a distant aspiration; our work is already being adopted by leading system operators, regulators, and philanthropic partners.

We are currently looking for a shared Executive Assistant to support 3 members of our Senior Leadership Team. This role is ideal for someone who thrives on working autonomously, with a high level of trust, and helping leaders do their best work while juggling multiple priorities with grace and precision.

🎯 About the Role

As an Executive Assistant to 3 of our Directors, you will be the right hand to three very busy members of our senior leadership team—supporting their daily operations, optimizing time management, and ensuring a smooth flow of information across the company.

You will be the trusted point of contact between them and a variety of internal and external stakeholders. You will also perform various administrative tasks, sometimes on tight deadlines, and will be required to manage your workflow autonomously across the 3 Directors, prioritizing and reprioritizing as necessary.

This is a remote-first position that requires a high degree of discretion, initiative, self-management, professionalism, and confidentiality. Language proficiency in English is required, as our working language is English. Proficiency in other languages, particularly German, French, or Spanish, is an advantage.

We’re all about transparency, and want to give you the best possible opportunity to prepare for any potential interviews. To learn a bit more about the people you’ll be working most closely with, click here:

Our Head of People (aka your future Manager), Quintin Coetzee
Our Head of Modeling Tools & Data, Hazem Abdel-Khalek
Our Head of Research & Market Development, Harry van der Weijde
Our Head of Energy System Modeling, Martha Frysztacki

From this group, Quintin will be your go-to for any people management-related matters. Meanwhile, your tasks will be allocated by a combination of Harry, Hazem, and Martha, based on operational requirements.

🛠️ Your Key Responsibilities

Calendar & Time Management: Proactively manage complex calendars across multiple time zones, prioritize and process scheduling requests, and protect leadership focus time.
Meeting Coordination: Prepare agendas, manage logistics, take comprehensive notes (minutes), and follow up on action items. Sometimes you’ll attend meetings on behalf of someone else.
Communication Management: Draft, translate, and respond to professional correspondence from internal and external stakeholders (emails, documents, memos), liaising with other staff to get input where required. This includes keeping our CRM up-to-date, as well as responding timeously to queries and flagging any potential issues to relevant parties.
Travel Planning: Organize international and domestic travel, accommodations, and itineraries, for things such as conferences, client pitches, and in-person meetings.
Documentation & Filing: Keep administrative platforms and records up to date, including presentations, contracts, and other and sensitive documents.
Event Assistance: Helping to organize events that OET may host or take part in.
General Admin: Help fill in and format applications, project briefs, tenders, internal and external presentations, research documents, grant applications, and historical (archival) documents for internal use.
Stakeholder Liaison: Act as a communication hub between leadership and internal teams, including our various Heads of Department, Team Leads, and Lead Maintainers.
Project Assistance: Provide project support (e.g., setting up workflows on tools like Asana, following up on tasks, etc.) This requires oversight of all tasks that are being worked on by the leadership team members in question, so that you have good context with which to make decisions.
Other Assistance: various other ad hoc administrative tasks, including those relating to our Business Development activities, e.g., finding the right person at a potential client a business developer should talk to.
