Come work with us. We don’t bite.

We’re a close knit, friendly and enthusiastic group of developers, testers, user experience experts and project managers based in the heart of the beautiful city of York.


Right now we are looking for people to join us in the following roles:

Enabling quality

We’re passionate about the quality of the things we make and the way we go about making them. We want to help the people we work with — both clients and team members — achieve success that’s meaningful to them; whether that’s an improved bottom line, delighted customers, career progression, new skills or a better work/life balance.

Isotoma was set up by developers and the development process is at the heart of everything we do. We understand that a good working environment and lack of distractions are absolutely key to concentration and good code, and we strive to provide the best working environment we can. We’re a family friendly employer too (with, amongst other things, flexible hours and a health plan); all of which is focussed on doing everything we can to ensure that you’re able to get the best out of everything you do.


You need to concentrate. We know that. Our offices are quiet, clean and friendly. They’re modern but characterful, and ideally located; our HQ is in the very centre of the beautiful city of York. There’s lots of break out space for stand-ups and impromptu meetings, as well as formal meeting space for bigger, longer meetings. And there’s not a single phone in the office. Last but not least, we use Slack, so you can easily mute your colleagues when you’re getting into the flow.


Our development process is supported by a powerful toolchain; Git for version control, JIRA for ticketing, CircleCI for CI, CloudFormation for deployment, as well as AWS for hosting and delivery.

Every one of our projects invests in automated deployment tools, ensuring that new environments can be spun up with ease (usually with a single command). This, combined with Linux on the desktop, means that our team can each run a full production-like environment on their desks — meaning everyone understands what production looks like and everyone is developing and testing against a realistic environment. It makes releasing easier too.

As with AWS, Django, Node and React we’ll provide training in these tools, ensuring that everyone continues to develop their skills and keeps on learning.

Agile at the core

Not all of our projects are Agile end to end (it simply doesn’t work for some projects) but everything is run in an Agile way internally. Our development teams are small and mixed speciality, with a combination of developers, user experience and QA making up every team. We empower teams to make their own choices wherever possible, trusting them to know how best to meet the customer’s requirements with the skills they have between them. We’re proud to trust our team to deliver; that trust is what Isotoma is built on.

Open source

Isotoma was founded as an OSS business back in 2004, when everyone thought we were mad to do so. And although most of what we do is bespoke for our customers (and therefore owned by them) we release everything we can under an open source license.

We encourage participation in open source projects and do what we can to support projects our team have particular interests in. We’re particularly keen for you to attend and talk at conferences on subjects you’re passionate about.
