We are looking for a hands-on QA / Test Engineer to help improve the quality, consistency, and reliability of our Power Platform solutions.

Location: UK (Hybrid / Remote)

Department: Delivery / Engineering

Role type: Permanent, Full-time

We are very successful in our industry partnering with many managed service providers across the UK. We leapfrogged the market becoming leaders in a matter of months. Our customers always provide a 5-star rating, and we are very proud of the service we offer.

Valto is a UK-based Microsoft Solutions Partner that specialises in creating the intelligent workplace of the future. We help organisations of all sizes transform how they work by leveraging the full power of Microsoft technologies including Microsoft 365, SharePoint and Teams through to Azure, Power Platform, Data & AI and Copilot.

Founded in 2017 and headquartered in Chester, with offices in London and Southampton, Valto brings together a passionate team of engineers, developers, consultants and innovators dedicated to helping clients migrate, optimise and secure their digital estates.

Our mission is simple: to help our clients unleash technology in a way that’s meaningful, efficient and future-proof. Whether it’s building a modern intranet, automating complex workflows, migrating to the cloud or implementing AI tools. We combine deep Microsoft expertise with practical, business-led delivery.

At Valto you’ll join a collaborative, fast-moving team that values curiosity, initiative and continuous learning. We’ve built a culture where people are empowered to experiment, share knowledge and grow their careers alongside cutting-edge tech.

If you’re excited about driving innovation, working with great people and helping businesses navigate transformation then Valto is the place for you.

This role goes beyond traditional “end-of-line testing”. You will play a key role in shaping how testing is done across the team, introducing pragmatic test processes, and holding developers accountable for the quality of their own work.

Initially, the role will be heavily hands-on. Over time, you’ll help us move towards a more mature, structured approach to testing without introducing unnecessary bureaucracy.
