In essence, they are our “true north” that help us to navigate our organisation through prosperous times as well as uncertain periods. Our company beliefs and values are embodied in our culture. Whilst we celebrate the diversity of the people we work with, there are certain values and attributes all of us share – whatever your background, these are the qualities we are looking for in the people we hire: Commitment, Positive Realism, Ethics, Accountability, Humanity, Quality, and Delight.

What this role is about:

We’re looking for a highly skilled Senior Web Engineer with strong full stack experience in .NET to help design and build our next generation of web platforms.

This is a hands-on engineering role focused on delivering high-quality, scalable, and maintainable solutions across backend services, APIs, and web applications. You’ll play a key role in shaping technical solutions, contributing to architectural discussions, and driving engineering excellence through your day-to-day work.

What you’ll do:

As a Software Engineer, you will design and maintain high-performance backend services and RESTful APIs using the modern .NET ecosystem. Your role involves working across the full stack—including Blazor and JavaScript—while ensuring all code is clean, well-tested, and aligned with architectural best practices. You will actively uphold engineering standards by participating in code reviews, managing technical debt, and improving system observability. Collaboration is key, as you’ll partner with Product Owners, mobile teams, and QA to translate requirements into seamless, integrated technical solutions. Operating within an Agile environment, you will contribute to sprint planning and communicate clearly regarding progress and technical risks. Finally, you are expected to drive continuous improvement by staying current with industry trends and mentoring junior developers through knowledge sharing.

About You:

Candidates must possess at least four years of professional software development experience, specifically demonstrating a deep expertise in C# and the .NET ecosystem. You should be highly proficient in building resilient RESTful APIs and backend services while maintaining a strong grasp of web application architecture, scalability, and security. A proven track record in full-stack development is essential, encompassing technologies such as MVC, Blazor, JavaScript, TypeScript, and standard web styling. Beyond application logic, you will need extensive experience with relational databases—specifically PostgreSQL—and the ability to balance Entity Framework usage with optimized SQL queries. Success in this role requires a collaborative mindset, comfortable working within Agile/Scrum teams and utilizing modern Git workflows. Finally, you should pair sharp problem-solving skills and attention to detail with the ability to communicate complex technical concepts clearly to diverse stakeholders.

What we offer: We’re always looking for new ways to celebrate our people. You’ll be no different.

• The chance to work with a passionate team that’s working together everyday towards our shared big ambitious goal

• A dynamic, flexible and fun scale-up work environment with a highly talented team

• 26 days holiday per year, plus public holidays

• Private medical cover with Bupa for all our colleagues

• Pension scheme, offering up to 6% matching contribution

• Up to 20 Nomad Working Days per annum

• Electric Car Scheme

Flexible & Hybrid Working: We said you'll get freedom to work in a way that is best for you, and that extends to being in the office – or not.

Work better from home? No worries. Prefer the office? Come on down. We have 2 mandatory Townhall days; Spring and Autumn, where the whole business gets together. When you visit the office you won’t just find rows and rows of desks. No, you’ll find our colleagues meeting on the walking pads, having planning sessions over a game of tennis table or grabbing a bean bag in our ‘Quality’ collaborative space - that’s right we live our values so much, we named our meeting spaces after them.

You can also shape work around your life at Airbox Systems; most colleagues work our core hours of 9am-5pm with others flexibly between 7am-7pm. Whether you're fitting in a spin class or the school run, you'll have the flexibility for whatever matters most. All we ask in return is that you produce great work, but when you’re working with passionate people, that part comes naturally.
