Senior Software Engineer (.NET / C#)
£75,000 - £80,000 + Benefits
Are you a Senior .NET Engineer who enjoys building high-quality software and is excited by the future of AI?
We're working with a growing leader within the parking space that is investing heavily in both its engineering capability and AI strategy. They're looking for a Senior Software Engineer to help build modern cloud-based applications whilst playing an active role in introducing AI into their products and development processes.
It's a senior engineering position where you'll spend most of your time designing, building and delivering scalable software using C# and.NET, whilst having the opportunity to explore and implement technologies such as LLMs, Agentic AI and Machine Learning where they can genuinely add value.
If you're already experimenting with AI, building side projects, integrating LLMs into applications or simply passionate about where software engineering is heading, we'd love to hear from you.
What you'll be doing
- Designing, developing and maintaining modern.NET applications.
- Building scalable APIs and cloud-native services.
- Working across the full software development lifecycle within an Agile environment.
- Collaborating with Product, Architecture and Engineering teams to deliver high-quality software.
- Exploring opportunities to introduce AI into products, internal tooling and engineering workflows.
- Contributing to architecture, code reviews and technical decision making.
- Mentoring junior engineers and helping drive engineering best practice.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we're looking for
- Strong commercial experience developing enterprise applications using C# and.NET.
- Experience working with Microsoft SQL Server, including writing and optimising queries, stored procedures and database objects.
- Commercial experience building cloud-based applications on Microsoft Azure, ideally including Azure Functions, Azure Storage and Service Bus.
- A solid understanding of software architecture, object-oriented design and building scalable, maintainable applications.
- Experience working with Git, Azure DevOps and modern CI/CD practices.
- The ability to mentor and support other developers through code reviews, technical guidance and knowledge sharing.
- Comfortable working across the full software development lifecycle, from requirements and technical design through to deployment and support.
- An interest in modern AI technologies such as LLMs, Agentic AI or Machine Learning, with either commercial experience or personal projects demonstrating how AI can improve products or engineering workflows.
- A collaborative approach with the confidence to contribute ideas, challenge technical decisions constructively and work closely with both technical and non-technical stakeholders.

- Experience with Python for automation, AI or machine learning projects.
- Exposure to Azure AI Services, Azure OpenAI or Microsoft AI tooling.
- Experience improving engineering processes, introducing automation or mentoring development teams.
- A genuine curiosity for emerging technologies and a desire to help shape how AI is adopted within modern software engineering.
This is an opportunity to join a business at an exciting point in its technology journey. You'll work on modern cloud-based software while helping shape how AI is adopted across the organisation. Rather than building AI for the sake of it, you'll be solving real engineering problems and creating products that make a genuine difference.
You'll be joining a collaborative engineering team where your ideas are encouraged, your technical opinion is valued, and you'll have the opportunity to influence both the software platform and the future use of AI within the business.
