Circular Wave is a small but perfectly formed team. We are building a healthcare worker marketplace that is saving the NHS and private healthcare organisations from their own horrifying inefficiency. At scale our product can save a cool £1.2 billion for our crumbling national treasure.

We currently have two highly active deployments, one in the NHS and one for a private healthcare provider. The results are exceptional: Circular Wave is bringing flexibility, transparency and auditability to temporary staffing whilst simultaneously saving money by reducing dependency on agencies.

As a startup business, we’ve relied until this point upon our company co-founder and CTO to provide the technical leadership and experience. We are now looking to free them up, and as such we are looking for a fantastic Senior Developer with at least 5 years of high-intensity commercial experience.

We care less about which specific technologies you have experience in, and more about your ability to solve difficult problems with speed and precision. The kinds of day-to-day challenges you will be facing in the short-term will be improving overall code quality, test coverage and development processes whilst building new features.

Future challenges will include re-architecting our backend, investigating and moving us onto new cloud providers, all whilst keeping our service running and our customers happy.

This is a great opportunity for those looking for a step up towards a leadership role within a growing team. You will be working closely alongside our Lead Developer, and the Development Team Lead as well as the Product Owners, to provide the benefit of your years of technical experience, to shape and implement the product (and the technology behind it). We are a team where ownership is everything, and we are actively looking forward to your input at every level. As a Senior Developer you will also be expected to provide support to the rest of the development team when needed, to help ensure that the whole team thrives and grows together.
