Principal Software Engineer
A global FinTech organisation is hiring a Principal Software Engineer to bring senior technical expertise across multiple engineering teams, with C# and.NET at the core.
You’ll be part of a small, highly skilled central team, working across the wider engineering function to tackle complex problems, influence technical decisions and help teams deliver.
This is a hands-on technical leadership role. You’ll shape architecture, write code and get involved where your experience adds the most value. Your involvement could range from a quick intervention to several months embedded with a delivery team. You’ll also take ownership of a handful of projects from the central team.
This is a chance to work across the technology estate, rather than being tied to a single product. You’ll see different teams, architectures and challenges while remaining close to the code and having genuine technical influence.
What you'll do:
