Is it time to step into a role where you take real ownership of complex, high-precision technology? An innovative Oxfordshire-based company is seeking a Senior Software Engineer to help shape and deliver the software behind next-generation systems. This is a hands-on role combining technical leadership with close collaboration across software and advanced hardware teams. You will play a key role in designing and developing robust applications that directly control precision hardware platforms. The position goes beyond feature delivery. You will influence architecture, strengthen engineering standards, support system deployments and mentor a small team, while remaining actively involved in coding. This opportunity would suit an experienced engineer with a strong background in C# and .NET, alongside Python for tooling or data work. Experience developing software that interfaces with hardware systems is important, particularly where reliability, timing and real-world performance matter. You should also be confident mentoring or technically guiding other engineers. Experience within industrial systems, cloud-connected platforms, networking or security would be advantageous. Salary: 65,000 to 70,000.
