Senior Frontend Engineer - React JS Role

Role Overview

As a Senior Frontend Engineer, you'll architect and implement responsive React applications that power client products, directly influencing user engagement and conversion rates. Day-to-day involves collaborating with designers and backend teams to turn wireframes into pixel-perfect, accessible interfaces. Your work impacts business outcomes, like boosting a client's site speed by 50% to reduce bounce rates.

Detailed Responsibilities

• Lead development of complex React components using hooks, context API, and state management like Redux or Zustand.
• Optimize frontend performance with tools like Lighthouse, code-splitting, and lazy loading for sub-2-second load times.
• Integrate APIs via GraphQL or REST, handling authentication with JWT or OAuth.
• Conduct code reviews, mentor juniors, and enforce best practices like TypeScript and ESLint.
• Collaborate on design systems using Storybook and Figma for consistent UI across projects.
• Deploy to Vercel or Netlify, monitoring with Sentry for error tracking and analytics.
• Prototype new features with Next.js for SSR/SSG to enhance SEO and user experience.

Day-to-Day Workflow

Your day starts with a 15-minute Slack standup to sync on priorities, followed by deep work on feature branches using GitHub. Mid-morning, you'll pair-program with a designer on tricky animations via CSS-in-JS like Emotion. Afternoons involve testing with Jest and React Testing Library, then PR reviews before EOD demos. Expect 6-8 hours of focused coding, with flexibility for async communication in this remote setup.

Tools and Technologies

• Core Stack: React 18+, Next.js, TypeScript
• State & UI: Redux Toolkit, Tailwind CSS, Headless UI
• DevOps: GitHub Actions, Vercel, Docker
• Testing/Monitoring: Jest, Cypress, Sentry
• Design/Collab: Figma, Storybook, Notion

Skills and Requirements

Technical Skills

Proficiency in React JS is non-negotiable, including advanced hooks, custom hooks, and performance tuning. Expect hands-on with Next.js for app routing and SSR, plus TypeScript for type-safe code. Familiarity with GraphQL via Apollo Client and modern CSS frameworks like Tailwind rounds out the stack.

Soft Skills

Strong communication shines in remote settings—clearly articulate trade-offs in Slack threads or Zoom retros. Problem-solving under ambiguity is key, as client scopes evolve mid-project. Team players who thrive in async environments, proactively sharing progress and seeking feedback, excel here.

Experience Expectations

Senior level demands 4+ years in frontend, with a portfolio showcasing 3-5 React projects deployed live (e.g., GitHub repos with 100+ stars). Open-source contributions or freelance gigs add weight. No GPA cutoff, but demonstrated impact—like "Optimized app reducing load time by 40%"—trumps academics.

Salary and Benefits

For a remote Senior Frontend Engineer - React JS at Robusta Studio, expect $120,000-$160,000 annually, competitive with US agency rates per Levels.fyi data. Seniors hit the upper end with proven leadership. Benefits include full health coverage, $2,000 annual learning stipend for Udemy or conferences, and unlimited PTO.

Remote perks feature ergonomic setup reimbursements up to $1,000 and flexible hours across time zones. Many interns convert to full-time post-6 months, with 70% retention rate. Equity options vest after year one for long-termers.

Robusta Studio Hiring Process

Step-by-Step Hiring Stages

1. Application: Submit resume, LinkedIn, and portfolio via their site or LinkedIn.
2. Screening: 30-min recruiter call on experience and culture fit.
3. Assignment: 4-hour take-home building a React dashboard with API mock.
4. Interviews: Technical deep-dive (1hr), system design (1hr), behavioral with CTO (45min).

Screening Methods

Their ATS scans for keywords like "React", "TypeScript", "Next.js"—tailor your resume accordingly. Portfolios must link live demos; static PDFs get skipped. Cover letters highlighting a specific Robusta project (e.g., their portfolio site) boost visibility.

Interview Preparation

Example Interview Questions

• "Walk us through optimizing a slow React list component rendering 10k items."
• "Design a reusable modal system with accessibility in mind—code it live."

• "Explain React 18's concurrent features and when to use Suspense."

How to Answer

Use the STAR method: Situation, Task, Action, Result. For tech questions, think aloud—pseudocode first, then refine. Example: For optimization, discuss memoization, virtualization with react-window, then share metrics from past work. Practice on Pramp or LeetCode for live coding poise.

What Recruiters Evaluate

They prioritize code quality, problem-solving depth, and remote collaboration signals. Clean, scalable code trumps perfect algorithms. Cultural add: initiative and humility—candidates who ask smart follow-ups stand out.
