Acknowledgement design, build and operate software.

We’re looking for a senior software application developer to join us and work on the development of one of our own products, a B2B customer service application. It’s a multi-tier, multi-technology suite of applications centred around a highly-scalable Node.js layer, JSON:API microservices, PHP back-ends and modern JavaScript front-ends.

You will be the primary developer working on the front-end of this application so this role will suit you if you are an experienced and highly capable developer who is happy to be autonomous and obsessed with high quality work and attention to detail.

We are based in Central London and this is an office based role. We are not interested in remote workers for this position. We are open minded re perm / freelance but this is a full time role and must be your only working commitment.
