That's why if there's scope in the working day, we have flexibility around our core hours to do the things that matter to you. We also know some work is done better at home and some is done better in the office, and that a one-size-fits-all approach doesn't enable high performance. That's why 10x is a remote-enabled organisation and supports agile working. This role has an office attendance requirement of approx. 2 days per quarter, in agreement with your line manager. Additionally, everyone comes together at our quarterly 10x Together Days to collaborate, align on strategy, and socialise. As all employees are employed on London-based contracts, commuting costs to the office are covered by employees and not by 10x. Equal opportunities for all At 10x, we are passionate about our people and are committed to fostering a more diverse and inclusive culture. We are building a community where every 10xer can bring their authentic self to work and feel empowered to reach their full potential. Our many employee networks help amplify this vision. Alongside assessing technical capabilities to do the role, our assessment process will identify what you can uniquely bring to our 10x teams, and the potential you have to thrive here (learn more about our approach to assessment). Common to every role that 10xers perform, are 3 core competencies that we look for in our future 10xers - Business Impact, Change Driver & Delivery Excellence. We are committed to ensuring all job applicants are treated equally and fairly and encourage applicants of all ethnicities, race, religion, sex, sexual orientation, gender identity, family or parental status, age, neurodiversity or disability status. Accommodations We recognise not everyone is the same. In fact, we embrace difference. If you require any form of accommodation during the interview process, please tell us so we can make arrangements to support. Any information that you provide will be recorded and maintained confidentially.
