Company values
As an impact-led technology company, our values help us collaborate and create work that drives change.
We support a culture of continuous learning and experimentation. We learn from each other through weekly teach-ins and innovate together on 'Neptune Days'; internal, cross-functional hackathons.
We have a truly international and diverse team, and we're fiercely proud of it. TransitionZero proactively maintains an environment that allows everyone to contribute, to achieve and to be heard, no matter their seniority or communication style. When we get it wrong, we listen and when we need to rest, we take the time to recharge and unplug.
We're agile, with cross-functional teams pulling together on shared projects. Impactful energy transition research requires both precision and pace. We collaborate on our objectives and prioritise ruthlessly.
We prioritise clarity, transparency, and fairness to ensure that every team member is heard and valued. Through narrative memos, project teams fine-tune their thinking before presenting ideas to the rest of the company.
