Salary at every level, the technical track versus management, and what to build next.
Typical years are a guide, not a rule. Impact matters more than tenure.
Salary ranges reflect the UK market in 2026. Ranges widen at senior levels because company size and equity vary significantly.
Senior frontend developers on the technical track move toward frontend architecture: owning design system architecture, performance engineering, and accessibility strategy across an entire product. Engineers who combine deep React expertise with Web Core Vitals optimisation and accessibility engineering are in the strongest position at the senior end of the market. The role at Principal level is largely about setting standards rather than shipping features.
Senior Frontend Developer to Lead Frontend Developer to Engineering Manager (Frontend) to VP Engineering. The management step follows the same pattern as general software engineering. Successful transitions typically require having informally led the team before making the formal move.
Companies actively hiring for this role in UK right now.
Frontend Developers move into Full Stack roles by learning Node.js or an alternative backend language and cloud deployment. The path is well-documented and widely trodden.
Most developers reach Senior between years 4 and 7. Companies look for engineers who have owned a significant feature or product area end-to-end, not just completed assigned tickets. Demonstrated ownership of performance optimisation, accessibility implementation, or design system development moves the timeline forward.
Around €18,000 to €25,000 at the median. A strong mid-level frontend developer earns €58 to €72k; a freshly promoted Senior earns €78 to €95k at most Dublin tech companies. The gap is meaningful and worth actively pursuing rather than waiting for.
It depends on the type of work you want to do. Full Stack opens more roles, particularly at startups and smaller companies. Frontend specialisation commands a higher ceiling at product companies that value deep UI expertise. If you are at a company where frontend work is treated as a commodity, learning backend skills is worth the investment. If you are at a company that ships complex, high-traffic UIs, frontend depth pays well.
It exists at larger companies. Staff Frontend Developer and Frontend Architect roles are real at companies like Workday, Google, and Zalando in Dublin. At most companies under 100 engineers, the track above Senior is informal. Design system ownership and performance architecture are the areas where senior technical contributors create the most clearly demonstrable impact.
