HOW YOU WILL MAKE A DIFFERENCE

About you:

Do you want to spend your working time making a difference in the world around you? Are you motivated by impactful work? Do you have a passion for software that directly contributes to patient safety, and troubleshooting complex challenges? If so, then a career with STERIS in our Software Development team could be a great fit for you.

About Us:

At STERIS we are a leading global provider of products and services that support patient care with an emphasis on infection prevention. Our mission is to help our customers create a healthier and safer world. Working at STERIS, you GROW, LEARN and MAKE A DIFFERENCE.

We are currently recruiting for a Senior Software Developer vacancy. This is an excellent opportunity to join us at a specialist level in a division that drives the business forwards through innovation.

WHAT YOU WILL DO

The Senior Software Developer is a hands‑on, technically experienced engineer responsible for designing, building, and maintaining business‑critical software across both legacy on‑premise systems and modern web platforms. This role balances the maintenance and evolution of existing C#/.NET, WPF, WCF, and SQL‑based applications with the delivery of new functionality using modern .NET, web, and front‑end technologies.

The Senior Software Developer works with a high degree of autonomy, contributes to technical decision‑making, mentors other engineers, and helps drive improvements in code quality, system reliability, and engineering practices. This is a technical role with no formal line‑management responsibility.

Design, develop, test, and maintain software across legacy on‑premise systems and modern web‑based applications.
Build and enhance solutions using C#, SQL Server, ASP.NET MVC, ASP.NET Core, and modern .NET versions.
Maintain, refactor, and modernise existing WPF and WCF applications where appropriate.
Develop and support React based web front ends in collaboration with Product and UX stakeholders.
Design and implement RESTful APIs and service based integrations.
Ensure software solutions are secure, scalable, maintainable, and well documented.
Provide technical leadership through mentoring, code reviews, and setting engineering best practices.
Contribute to technical design, estimation, and architectural discussions, acting as an escalation point for complex issues.
Identify, prioritise, and reduce technical debt and operational risk.
Work effectively within Agile delivery processes, collaborating closely with QA, DevOps, and cross functional teams.

Required Experience

Experience

5+ years of professional software development experience
Proven experience working with complex, production legacy systems as well as modern application stacks
Demonstrated ability to work independently, take ownership, and deliver high‑quality solutions

Core Technical Skills

Strong proficiency in C# and .NET
Experience with ASP.NET MVC and ASP.NET Core
Experience maintaining and evolving WPF and WCF applications
Solid SQL Server knowledge, including data modelling and performance considerations
Source control using Git

Modern Web & Front‑End Skills

Experience building or supporting applications using React (TypeScript preferred)
Strong understanding of modern JavaScript, HTML5, and CSS
Experience consuming and designing APIs

Engineering & Delivery Practices

Automated testing (unit, integration, API)
CI/CD pipelines (e.g. Azure DevOps, GitHub Actions, or similar)
Agile delivery methodologies
Secure coding and performance optimisation practices

Preferred Experience

Skills

STERIS is a leading global provider of products and services that support patient care with an emphasis on infection prevention. WE HELP OUR CUSTOMERS CREATE A HEALTHIER AND SAFER WORLD by providing innovative healthcare and life sciences products and services around the globe. For more information, visit www.steris.com.
