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 part of a multidisciplinary team working at the intersection of software engineering, numerical modelling, and domain science. Our teams collaborate closely with clients, scientists, and engineers to build robust, scalable software that supports advanced research and operational decision‑making.

In the near to medium term, this role involves significant on‑site working with a client in the Basingstoke area, giving you direct exposure to real‑world problems and stakeholders.

This is an excellent opportunity for someone who wants to deepen their technical knowledge while developing the skills needed to mentor others, influence technical direction, and lead work packages or projects.

DUTIES AND RESPONSIBILITIES

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.

EXPERIENCE REQUIRED

We are looking for someone who has

Professional experience developing software in Java and C++.
Practical experience applying object‑oriented design principles and modular software architectures.
Familiarity with collaborative development practices, including Git and CI/CD pipelines.
Experience working across the full software development lifecycle, including design, implementation, testing, and maintenance.
Knowledge of software testing techniques and a commitment to writing reliable, maintainable code.
Solid analytical and problem‑solving skills, with the ability to work effectively both independently and as part of a multidisciplinary team.
The confidence and communication skills to work directly with clients and technical stakeholders.
Sole UK nationality, due to the nature of the work.

Desirable experience includes

Experience writing unit tests using JUnit and Google Test Frameworks.
Solid understanding of numerical methods and scientific computing principles.
Background in physics, applied mathematics, or engineering.
Experience in development with Fortran 90.
Experience in SQL database development.
Experience using the Java Spring framework.
Experience working in the defence sector.
