INTEREST
Are you a software developer who enjoys solving complex problems and wants to grow into a technical leadership role? This position sits within Frazer‑Nash Consultancy’s Software and Digital Architecture capability, where software underpins our ability to deliver high‑impact solutions to critical national challenges.

You will be expected to:
- Design, develop, and maintain high‑quality software components using Java and C++, with a focus on robustness, performance, and maintainability.
- Implement and extend code that interacts with a flexible integration framework for solver coupling and data exchange.
- Work closely with clients, domain scientists, and computational engineers—often on‑site—to understand requirements and translate them into effective software solutions.
- Contribute to defining and evolving software architecture, balancing performance, scalability, and long‑term maintainability.
- Write clean, well‑documented, and testable code in line with scientific software development best practices.
- Participate regularly in code reviews, debugging sessions, and performance profiling to improve code quality across the team.
- Support and mentor junior developers through technical guidance, constructive review, and knowledge sharing.
- Over time, take on increasing responsibility for guiding technical direction and contributing to the planning, delivery, and management of project work.
- Help develop client relationships and contribute to development of new business, such as through writing effective proposals.
- Thrive in a consultancy environment solving real-world, high-consequence challenges.
