About Radical
Radical is a dynamic, UK-based digital product agency that specialises in the definition, design, development, and support of bespoke web and mobile applications.
We see ourselves as the long-term digital product partner for companies looking to continuously improve their applications through expert execution, transparent development, and strategic support. We bring clarity to complex ideas and deliver high-quality, fully supported digital products.
This is a UK remote role, with fully funded, occasional in person meetings or social events (approximately once per quarter).
What You’ll Be Doing
We are seeking an experienced Backend Developer to be a key player in our cross functional teams.
You will be responsible for the reliable delivery of diverse client projects, ranging from rapid proof of concept work to the development and maintenance of large scale production applications. The pace of agency work requires an ability to switch context, apply expertise across multiple projects, and collaborate directly with clients and internal stakeholders.
Core responsibilities will include:
- Working across 2 key technologies: PHP Laravel and C# .NET.
- Technical planning and efficient delivery of solutions.
- Evaluating technical trade-offs between monolithic and service-oriented approaches across Laravel and.NET builds.
- Analysing existing codebases to improve query performance, reduce technical debt, and ensure data integrity.
- Collaborate with team members to deliver digital solutions for clients on time and to specification.
- Proactively research and recommend technical solutions, bringing new ideas to the table, and demonstrating a strong understanding of available off the shelf tools, architectural patterns, and development methodologies.
- Work on greenfield projects and the maintenance of existing projects for a variety of clients.
- Write clean and scalable code.
- Document technical solutions and participate in technical workshops.

Application process
Stage 1: Interest
Apply via this ad. We’ll review candidates and create a first stage shortlist.
Stage 2: First Stage Interview
We will invite shortlisted candidates to a first stage video interview, in which we can find out a little more about each other.
Stage 3: Final Stage Interview
In a final stage interview (video call or in-person), we will conduct a structured technical Q&A with our engineering team. Rather than an offline coding task, this live conversation will focus on:
- System & API Architecture: Exploring how you design scalable backend structures and integrate third-party services.
- Framework Depth: Discussing "under the hood" mechanics, performance optimisation, and memory management in both Laravel and.NET.
- Real-World Trade-Offs: Evaluating how you handle technical debt, database bottlenecks, and refactoring legacy codebases in production environments.
Once final interviews are complete we will be ready to submit a formal offer to the selected candidate.
