Frontend Developer.

React developers currently earn a slight premium (5 to 10%) due to market demand, but the gap is narrowing as Vue and Svelte gain adoption. What matters more is depth of knowledge in any framework combined with strong fundamentals in JavaScript, accessibility, and performance optimization.

TypeScript has become a near requirement at most companies, and proficiency is now expected rather than a bonus. That said, developers with deep TypeScript skills including generic types, utility types, and type safe API integration are more attractive to employers and can negotiate 5 to 15% higher offers.

In Burlington, large enterprises typically pay Frontend Developers 10 to 20% more in base salary than small companies, but startups often compensate with equity that can exceed base salary value. Equity at tech companies adds $15,000 to $80,000 annually for senior roles. The $92,000 to $158,000 range reflects this entire spectrum.

Many Burlington employers are shifting toward skills based hiring for Frontend Developer positions. While a degree can accelerate your path to the median salary of $120,000, demonstrated experience, certifications, and a strong portfolio carry significant weight. Candidates without degrees may start closer to $92,000 but can reach the 75th percentile with three to five years of proven results.

Framework expertise (React, Vue, or Angular), performance optimization skills, and experience with design systems drive the biggest differences. Developers who can build accessible, responsive interfaces with strong TypeScript skills earn premiums. Mobile web expertise and experience with server side rendering frameworks like Next.js are increasingly valued. In Burlington, these factors can push compensation from the 25th percentile of $92,000 to the 75th percentile of $158,000 or beyond.
