Resume Writing Tips for Senior Frontend Engineers

Lead with Platform-Level Impact

Senior engineers architect platforms, not features. Lead with user scale (10M+), teams enabled (5 product teams), system-wide improvements (65% performance gain). Show you think at the platform level—your decisions affect the entire organization.

Demonstrate Strategic Technical Leadership

Include bullets on technical strategy, roadmap planning, architecture decisions, technology evaluations. Show you drive long-term technical direction: adopted Next.js, established patterns, led migrations. Senior level means shaping the future, not just executing.

Showcase Team Building and Organizational Impact

Senior engineers multiply impact through people. Quantify: engineers mentored (8), promotions enabled (5), guild leadership (15 engineers), standards established. Show you build capabilities and culture, not just systems.

Balance Deep Technical Expertise with Business Value

Senior engineers are both technical experts and business partners. Include deep technical details (micro-frontends, SSR, module federation) balanced with business outcomes (18% conversion lift, deployment velocity, team autonomy). Connect technical decisions to business impact.

Position for Staff/Principal Track

List 15-20 skills spanning architecture (micro-frontends, SSR), performance (Core Web Vitals, optimization), infrastructure (build systems, CI/CD), leadership, and strategy. Show you're not just executing—you're defining how frontend engineering works at your org.
