How You’ll Support Our Mission!

Our Suite and Tools Product team enables new clients to onboard onto ESO software seamlessly, as well as upgrading existing clients to newer, more powerful products.

Reporting to the Development Manager you will be part of our Product Engineering team based in Belfast. 

What You’ll Be Doing – the day-to-day:

You can expect to work across the whole stack from front-end SPAs, through back-end services, containers, serverless, DevOps, SQL, and noSQL to name but a few. We value competency, tenacity and problem-solving, and you’ll find plenty of opportunities to learn new skills and technologies, or even introduce your own best practices into your new team.  

Our Current Stack: C#, .NET Core, Angular, Typescript; Azure DevOps, Terraform, Azure PAAS / Serverless; EF Core, SQL Server, Redis; BDD, NUnit, Cypress, Sonar; Application Insights, New Relic.

We are an Agile development shop and interact regularly with project stakeholders, including demos from each sprint.  To support this methodology, we use regular retrospectives and objective measurements to drive continuous improvement and empower our developers to make informed technology and implementation decisions. As part of the development process, you will be involved in design sessions, and you’ll have the opportunity to learn and teach through peer review of code and of completed solutions.

  • 3+ years’ experience in software engineering and software design and architecture principles

  • Logging, monitoring and alerting frameworks (e.g. Serilog, Application Insights, New Relic
