Are you an accomplished senior software developer with a proven track record in .NET?

Join us at an exciting time in our journey, where you’ll help shape the future of our products as we modernise our enterprise applications with latest .NET technologies and event-driven SaaS microservice architecture to deliver enterprise-scale solutions.

At Advanced Secure Technologies, we’re a fast-growing, innovative company on a mission to protect organisations from document fraud through cutting-edge security solutions. Based on site in St Mellons, Cardiff, we’re expanding and need another skilled senior developer to help us scale.

Share ideas, solve complex technical problems, and help shape the future technical direction, architecture and engineering standards of our products.
Take ownership of team sprint delivery, facilitating sprint activities, coordinating priorities, resolving blockers and helping ensure releases and wider project deliverables remain on track and delivered successfully.
Support and mentor other developers through technical guidance, collaboration, code reviews and sharing best practice, while also supporting their career development and contributing to a collaborative, high-performing engineering culture.

Strong problem-solving skills, attention to detail, excellent organisation and clear communication skills, with the ability to collaborate effectively across diverse engineering teams and the wider business.
Experience mentoring, guiding and supporting other developers, helping them grow through collaboration, technical guidance and knowledge sharing.

Bonus points for:

Working with enterprise-scale software, microservices, event-driven architecture or SaaS product development.
Experience with TDD, DDD, secure coding/OWASP practices, Azure DevOps, CI/CD pipelines and cloud platforms like Azure.
Experience with some of the tech we use: .NET Blazor, EF Core, SQL, Redis, Elasticsearch, RabbitMQ, Docker, Kubernetes or Blockchain.
Experience using AI tools to improve developer effectiveness, team productivity and the quality or speed of software delivery.

Benefits

What we offer:

Competitive salary £55,000 - £65,000 (DOE) + monthly performance bonus.
A clear career pathway through our Senior Developer grades and beyond with mentoring and skill development support.
25 days holiday + Bank Holidays.

We’re an office-based team because our culture thrives on collaboration and hands-on support, especially as we grow quickly and onboard new team members. While we don’t offer fully remote or fixed hybrid work, we’re flexible when life happens – ad hoc home working is always an option.
