Outsystems Developer

 

LET’S CUT STRAIGHT TO IT

 

At Severn Trent, our people are at the heart of everything we do. We’re in the top 5% of utility companies worldwide for employee engagement, and we’re equally proud of our strong Glassdoor score — reflecting how much our people love working here.   

 

Join us to make a positive impact on the environment and our communities, while being valued and supported in a truly inclusive workplace.  

 

If you want to do more, because you care, we want you on our team.  

 

LET’S TELL YOU MORE

 

Placing customers at the centre of everything we do is precisely why this exciting new opportunity for an Outsystems Developer has arisen on an 18-month fixed term contract. As a business, we are committed to designing, developing, and launching low-code, small-footprint applications that enable quick, reliable, and accessible information capture for customers, colleagues and stakeholders alike. These solutions are engineered for easy maintenance and rapid value realisation.

 

You will be ensuring that there is a seamless integration of the technology from both front-end and back-end components with the aim to deliver a robust, scalable, and efficient solution which meets both our businesses requirements but also enhances the user experience.

 

Some of the Key accountabilities in this role are: -

 

  • Develop scalable web and mobile applications using the OutSystems low-code platform
  • Collaborate with product owners, business analysts and end users to gather and refine requirements incorporated into technical designs
  • Integrate solutions with office and ERP applications like M365, SAP
  • Build APIs and reusable components to support secure, reliable data exchange with partners and regulatory systems
  • Ensure all applications meet Severn Trent specific standards for performance, security, and compliance
  • Document application architecture, configurations, and development workflows
  • Troubleshoot and resolve bugs and production issues with urgency and precision

 

You'll be based at our Severn Trent Centre head office in Coventry.  You’ll work within a project team of 5 dedicated people. With this being such a critical role, we’re looking for someone who can join us 37 hours a week, Monday to Friday, with three days at least in the office. 

 

HOW WE WORK 

 

You'll join a caring culture that collaborates to achieve, grow, and develop. Our employee engagement scores are among the highest globally in energy and utilities. That’s why, we value in-person moments to keep our culture alive but also understand the flexibility working from home can bring. So, you'll usually find us in the office, but working from home is supported, when you need it.  

 

WHAT WE’RE LOOKING FOR

 

You’ll need to have experience of working in an Agile culture that includes joint team outcomes, empowerment, commitments, and drives collaborative process.

 

Having working software development experience and a proven track record of delivering high-quality software solutions in a fast-paced environment is a must. 

 

Proving your experience in both front-end and back-end hands-on development experience with OutSystems (Reactive Web, Traditional Web, or Mobile) using OutSystems Studio and Service Studio, is essential. Outsystems simplifies the app development process but understanding its low-code environment to proficiently use drag-and-drop features, widgets, and templates is a must.

 

You will have skills in creating, managing, and optimizing databases within the OutSystems environment.

 

Proficiency in REST/SOAP APIs, SQL Server or Oracle databases, and web technologies like HTML, CSS, and JavaScript within Outsystems platform.

 

You will be proficient in front-end technologies such as HTML, CSS, and JavaScript, along with UX design principles. .

 

An OutSystems Associate or Professional certification is desirable. Knowledge of DevOps tools (Github, Azure DevOps), version control systems or container-based deployments will be an advantage.

 

Skills and experience are important, but character, positivity, and a caring attitude matter too.  We welcome people from all walks of life and celebrate individuality as we know diverse minds, experiences and backgrounds help us to learn and better serve our communities. We seek people who get involved, want to be part of something bigger, and make a difference because they care.
