Your new company

You'll be joining a cutting-edge engineering and technology organisation that has grown rapidly in the UK, now pushing into global markets. Formed by world leading experts in science/software the business is redefining how high-performance components are designed.

You'll be based from their head office in Oxford 3-5 days a week, joining their R&D function and will likely require your own vehicle.

Your new role

This role sits in the core Development team and would suit a Software Engineer with a passion for Science/Applied Engineering with commercial Full Stack experience. You'll participate in the full development lifecycle working on proprietary applications that underpin the business rather than customer-facing websites or generic enterprise systems.

The right person will be motivated and hungry to solve first-of-their-kind challenges building proprietary software that makes a difference in the world. You will design, develop and maintain innovative tools spanning data management, traceability, visualisation, predictive modelling, material and component design, and production quality assurance. You'll work closely with process engineers, technicians and material scientists to deliver high quality, intelligent solutions that support cutting edge manufacturing and materials development.

With the rapid expansion and new investment into the company it's an exciting time to be joining with solid progression opportunities. You're also safe in the knowledge the future is bright as their customer list boasts some of the worlds leading tech and engineering brands.

What you'll need to succeed

We're looking for candidates with a strong degree in a STEM or Computing discipline - ideally from a Russell Group University.

We need 2-8 years working in a commercial Software Engineering role using C# .Net. Ideally you'll have full stack experience with Blazor or JavaScript/TypeScript frameworks.

We are looking for robust OOP programming skills, software design patterns/best practices and practical experience applying TDD. Experience with Cloud services (AWS or Azure), Machine Learning, CI/CD and Containers would be standout.

Crucially we need Engineers who have taken ownership in projects. What you've individually contributed to projects must be evidenced on the CV.

What you'll get in return

The company offers 25 days' holiday plus bank holidays, flexible working hours, a pension with a 9% employer contribution, private healthcare covering dental & health screening.
