Business outlook
Pros
Strong engineering standards and high-quality codebase. Work on complex and critical financial systems with real-world impact. Good exposure to performance, numerical accuracy, and large-scale architectures. Smart and committed colleagues, with strong technical discussions.
Cons
Limited flexibility to explore new technical areas outside your assigned scope. Learning curve can flatten after several years if you stay on the same perimeter. Processes and tooling can sometimes feel heavy.
