Hi, We’re Nexio Projects

At Nexio Projects, we firmly believe that everyone has the power to shape a more sustainable future. As a trusted advisor and partner to clients in a wide range of sectors, we simplify the challenges associated with sustainability and bring clarity and transparency to fuel bold action. We are facilitators and implementors at heart and strongly believe in the power of incremental change to shape a more sustainable future.

As a dynamic team, we form a motivated group of 30+ co-workers headquartered in Rotterdam, The Netherlands. We have cultivated a unique team spirit that is both impact-driven and purpose-oriented. We are humble, hardworking, and continuous learners.

Everyone’s voice can be heard, and promoting an environment where maximum potential can be reached is at our core. Because of this, we continuously look for enthusiastic intrapreneurs who can do things seriously without taking themselves too seriously.

Your typical week

It’s Monday morning, and you’re returning to the office refreshed from a great weekend. The week starts with our team meeting, where everyone reflects on the learnings of the past week and shares intentions for the coming one. This creates a space for alignment, awareness, and enthusiasm before stepping into the new week and allows everyone to get the latest updates from different departments while hearing about the organisation’s growth.

During the week, you can expect a combination of client-facing and managerial tasks. You are responsible for coordinating client projects from beginning to end while guiding a young and growing team of enthusiastic analysts and consultants to support you along the way. Every week is different, however. You will also be involved in other activities such as hosting webinars, working with Universities, writing and publishing articles, hosting internal lunch and learn sessions, and helping to land new clients—all of this with a strong emphasis on the good work-life balance, of course.

The week closes off on Friday at 5 p.m. with our gratitude award. This is the time to reflect on the successes and challenges of the week and, most importantly, to share what we’re grateful for. After this, our team is always keen to stay longer and enjoy some precious bonding time over beer, wine, and ginger beer – on the house.

Is this an environment you want to work in? Are you a curious person committed to helping businesses become a force for good? Do you love the buzzing energy of a team striving towards reaching a common goal? Then read on to learn more about the role.
