Software Engineer

IRIS provides integrated software across accountancy, finance, HR, payroll, education and business operations. Our approved company material confirms that IRIS supports more than 100,000 customers across 135 countries.

As a Software Engineer, you'll help develop the applications and data platforms behind that technology. You'll take ownership of small to medium-sized features through their complete lifecycle, delivering scalable, maintainable solutions and contributing to technical decisions within your feature scope.

It's a hands-on role with meaningful ownership, backed by experienced colleagues when you're tackling broader or more complex engineering challenges.

About the Team You'll Join

You'll work within an Agile, cross-functional environment, collaborating with Product Owners, QA, Design and fellow engineers to refine user stories and turn requirements into robust production software.

Your contribution won't stop at writing code. You'll take part in code reviews, pair programming and knowledge sharing, mentor junior colleagues and contribute to technical and architectural discussions.

What You'll Be Doing

You'll

• Deliver full-stack features from analysis through to production.
• Build backend services using C#, .NET Core, ASP.NET Core Web APIs and REST.
• Develop with modern frontend frameworks such as Angular, React or Vue.js, alongside TypeScript.
• Design and work with SQL Server and potentially CosmosDB or DynamoDB.
• Build and maintain microservices and robust APIs.
• Deploy containerised applications with Docker and Kubernetes using Azure or AWS.
• Extend CI/CD pipelines using Azure DevOps Pipelines or GitHub Actions.
• Apply automated testing and TDD/BDD practices, plus security and quality controls.
• Use observability tools such as DataDog, Application Insights or Amazon CloudWatch.
• Use AI-assisted engineering tools critically and responsibly across design, development, testing and debugging.
• Mentor junior engineers and contribute to effective Agile delivery.

What We're Looking For

You'll bring 2–4 years of professional software development experience and a track record of delivering software using Agile methodologies.

You'll need strong .NET/C# backend development skills, SQL Server experience and knowledge of scalable web applications and cloud deployments. We're also looking for experience or working knowledge across CI/CD, containerisation, Infrastructure as Code, automated testing, observability and clean architecture/SOLID principles.

Frontend experience with Angular, React or Vue.js is valuable, although a backend specialist with working frontend knowledge can also fit the role.

You'll be comfortable owning routine work independently, working with guidance on more complex features and providing technical support or mentoring to junior colleagues.

Experience with regulated or complex domains, event-driven architectures, GraphQL, real-time technologies, NoSQL databases or modern UI architecture patterns would be advantageous rather than essential.

Why Join Us?

This role offers the combination of hands-on engineering ownership and continued development. You'll broaden your skills across full-stack development, cloud infrastructure, modern DevOps and AI-assisted engineering while developing leadership skills through mentoring and architectural contribution.

You'll be contributing to IRIS's broader cloud transformation with technology used across accountancy, payroll, HR and education, while being supported by an experienced engineering community.
