Working from home

We aim to be as flexible as possible when it comes to working setups and lots of our team work from home on a regular basis. This means we generally work with a “remote first” approach even when we are in the office. Whether you end up working in the office or from home more you will need a good setup for working from home.

We’ll provide reasonable support and all the hardware you need to get started, but we do require that you have the following already in place:

  • A quiet working space at home where you can consistently take video calls without interruptions
  • An internet connection that supports your participation in video calls and access to our systems and services

Equal opportunities

Spektrix is an equal opportunities employer, we recruit regardless of race, religion, gender, gender identity, sexual orientation, age or disability status and look to employ from a wide range of backgrounds and experiences.

Confidence can sometimes hold us back from applying for a job. Studies show that women do not apply for roles unless they meet 100% of the requirements, whereas men apply when they meet at least 60% of the requirements. At Spektrix, we know that there's no such thing as a 'perfect' candidate. Spektrix is committed to creating an inclusive work environment, where our team members are supported in expressing themselves and delivering their best work. So however you

identify and whatever background you bring with you, please apply if this is a role that would make you excited to come into work every day.

Diversity in the workplace is hugely important to our working environment and to enable both individuals and Spektrix to thrive. By valuing each person’s differences we enable each person to contribute their unique experiences, strengths and viewpoints. Workplace diversity is something we aim to achieve and maintain at Spektrix, and we are pursuing a workforce that reflects the diversity of the communities we serve and work in. We aim to reflect this diversity in all departments and at all levels of seniority in the business, right up to the board.
