In this role, you will drive product development from ideation through to launch, creating a platform that offers loads of innovative trading options while remaining intuitive and accessible to the everyday user. You will be the key to transforming the vision of a DEX backend and CEX front-end into a tangible product that excites and engages users, making high-stakes trading both easy and inspiring.
If you are passionate about building standout products in the crypto space, thrive on leading cross-functional teams, and have a deep understanding of both DeFi and user-centred product design, this role is for you.

Throughout my time working with recruiters (and I’ve worked with a fair few!) I have never met a more technically adept, genuine, hardworking recruiter than Craig. It is clear that this attitude cascades down to his staff as the quality of candidates sent through are only of the highest quality. First impressions are massively important to me, and it’s his clear passion for this industry that means that Craig and his company will always be more first port of call when hiring.

Spectrum Search were excellent to work with and were able to deliver on time, within a tough market. They were thorough and detailed in their approach and really took the time to invest themselves into Vix Technology. Both Craig and Aaron were a pleasure to work with and I look forward to a continued partnership with them in the future

Global Recruitment Lead, Vix
Working with Morgan, Jordan and the team at Spectrum Search has been great, the roles we tasked them to fill were niche and they showed a real attention of detail to ensure they knew exactly what we needed. The questions they asked demonstrated a strong knowledge of DeFi and Blockchain Technology and this was reflected in the candidates delivered. Response time was impressive - given the short timescale we had to turn these processes around, it shows they have access to a very strong network of talent – I would not hesitate to work with them again
Brad Harrison

It was great working with Spectrum on this role – they were able to understand clearly what the requirements were for the role and understood the importance of this hire for us. We continue to work with Spectrum and Morgan on our other hiring needs

Hassan has demonstrated a professional approach while working with Seedify as a recruitment consultant. I was impressed by his attitude to work, his awareness of the Gamefi/Blockchain/Metaverse space and his willingness to help. Hassan is passionate about bringing the best talent, identifying companies' needs and cultural features. Also If you need someone more than just a recruitment consultant, someone who is actively involved in the process, I strongly recommend working with Hassan.

Engaging with Spectrum Search and Morgan allowed us the chance to re-evaluate how we were hiring, with their advice and market knowledge we were able to quickly devise a hiring plan and once agreed the turn around was impressive – we continue to work with Morgan and Spectrum Search on our growth
Senior HR Manager
We’ve started to co-operate with Spectrum Search two years ago, when Spectrum Search helped us to find 10 contractors to start almost immediately. Since then, Craig and his team found for more contractors and permanent employees (engineers, devops, qa, managers), always in record time and in locations that we preferred. I appreciate excellent pipeline and great communication and reaction times. We’ll definitely continue to use Spectrum Search services.
