Senior Developer

Cyclr is growing and we are seeking to recruit an experienced individual into our Senior Development team. With at least 5 years of relevant development experience under your belt you will be ready for your next move. Our team is small but highly efficient and Cyclr is growing fast. You will be joining our business at a formative stage and will have an opportunity to influence our development direction and growth.

As this is a critical team role, for the right person, there will also be potential to participate in the company equity scheme after an initial 12 month probationary period. 


Cyclr develops a powerful SaaS integration toolkit for SaaS companies. With Cyclr clients can quickly create, manage and deliver an amplified suite of integrations from within their own application. 

You’re technical but you’re also a skilled communicator 

We believe that the real art to software development is not just in the code itself, but  understanding the user journey and the ‘real-life’ commercial application of the code. All parts of our business touch our clients on their journey, we expect each and every member of the team to be prepared to interact externally. Our software platform is of critical importance to the clients that adopt it, to the extent that we view them as partners of our business. 

You’re a team player 

Our team work across multiple locations. As a result, we live in Slack and video chat to plan, organise, report, test, and generally ensure the smooth progress of projects. You should be able to collect, process, and summarise complex data into effective communication. 

We’re a young but growing business 

It will be exciting, things will evolve quickly, and you will get experience working on diverse projects. You will learn a lot and be able to have a meaningful impact on where Cyclr is heading. You will be helping to establish the foundations of a very large company. 

You will need to understand Cyclr’s full capabilities and its significance in the wider market. Conversations with users, partners, and colleagues, could lead to radical changes to features. We value ideas and initiative above all else: we expect everyone to be on the pulse of the technology we are integrating.
