What does a Software Engineer do?

Software Engineers design, build, test and operate software systems. Day-to-day work mixes coding (typically in Python, JavaScript / TypeScript, Java, Go or Ruby), technical design, code review, debugging, system architecture decisions, and on-call incident response. UK engineers operate across many product areas: consumer apps, fintech, infrastructure, AI / ML, gaming, defence and healthcare. The career has a famously flat hierarchy — Senior Engineer is a destination role at most companies, paying £80,000–£140,000+ at top UK employers without requiring management responsibility.
