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.
UK salary ranges
UK software engineering pay scales sharply by employer tier. London-based global tech offices (Google, Meta, Amazon, Apple) pay top of market — £70,000–£100,000 base for new graduates, plus equity and bonus pushing total comp to £120,000–£180,000. Top UK fintechs (Monzo, Wise, Revolut, Stripe) pay close to global tech. UK financial services (HSBC, Barclays, JPMorgan) pay £55,000–£80,000 base. Public sector and SMEs sit at £40,000–£55,000.
