Sr. Front End Developer (React.js) Role

Role Overview

As a Sr. Front End Developer, you'll craft responsive React components for Keeper's web apps, ensuring seamless user experiences in password vaults and sharing portals. Your code directly boosts user retention by making security feel intuitive rather than cumbersome. Expect to influence product roadmaps, collaborating with designers and backend teams on features that handle millions of daily logins.

Detailed Responsibilities

• Develop and optimize React.js applications using hooks, Redux, and Context API for state management.
• Build reusable UI components with TypeScript, Material-UI, and Tailwind CSS for cross-browser compatibility.
• Integrate RESTful APIs and WebSockets for real-time updates in dashboard views.
• Conduct code reviews, write unit tests with Jest and React Testing Library, and ensure 95%+ code coverage.
• Collaborate on accessibility (WCAG 2.1 AA) and performance optimizations, targeting Core Web Vitals scores above 90.
• Mentor junior devs and contribute to design system evolution using Storybook.

Day-to-Day Workflow

Your day kicks off with a quick standup in Slack or Zoom, reviewing overnight bugs from production monitoring via Sentry. Mornings focus on coding new features, like a drag-and-drop record organizer, pulling from Figma designs into a local Next.js dev server. Afternoons involve PR reviews, pairing sessions for tricky state logic, and A/B tests via Optimizely to validate UI changes.

By EOD, you deploy to staging via GitHub Actions CI/CD pipelines and log progress in Jira. Remote tools like Linear for tasks and Notion for docs keep everything synced across time zones.

Tools and Technologies

• Core Stack: React 18+, Next.js 14, TypeScript 5
• Styling: Tailwind CSS, Styled Components, Headless UI
• State/Build: Redux Toolkit, Zustand, Vite/Webpack
• Testing/Quality: Jest, Cypress, ESLint, Prettier
• Other: Figma, Storybook, Vercel for deployments

Skills and Requirements

Technical Skills

Keeper prioritizes deep React proficiency, including custom hooks, performance tuning with memoization, and SSR/SSG patterns in Next.js. Familiarity with secure coding practices, like sanitizing inputs to prevent XSS in credential forms, is non-negotiable. Bonus points for experience with PWAs, GraphQL via Apollo, or WebAuthn for passwordless auth.

Soft Skills

You'll thrive with strong communication to explain complex UI decisions to non-technical stakeholders. Problem-solving shines in debugging race conditions during live pair-programming. Team players who document code thoughtfully and adapt to feedback loops will fit Keeper's agile culture seamlessly.

Experience Expectations

Senior-level means 5+ years in front-end dev, with a portfolio showcasing 3+ React projects deployed at scale (e.g., 100k+ MAU). Side projects on GitHub with 50+ stars help, as does contributions to open-source like React repos. No strict GPA cutoff, but proven impact via case studies trumps academics.

Salary and Benefits

For a remote Sr. Front End Developer (React.js), expect $140,000–$175,000 base salary, aligning with market rates for senior React roles in cybersecurity. Total comp hits $170,000–$220,000 including bonuses (15–20% target) and equity grants vesting over 4 years. Benefits shine with full health coverage, 401k match up to 6%, and $2,000 annual learning stipend for React Conf or Udemy.

Remote perks include home office setup allowance ($1,000 one-time) and unlimited PTO with encouraged 20+ days off. High full-time conversion for strong performers, often with promotion paths to Lead Developer within 18 months.

Keeper Solutions Hiring Process

Step-by-Step Hiring Stages

1. Application: Submit resume, LinkedIn, and GitHub via Lever ATS on Keeper's careers page.
2. Screening: 30-min recruiter call assessing React experience and culture fit.
3. Assignment: 4-hour take-home task building a secure form component with tests.
4. Interviews: 4x 45-min rounds: technical deep-dive, system design, behavioral, and VP chat.
5. Offer: Detailed comp breakdown within 1 week post-final interview.

Application Timeline

Apply anytime—no deadline means rolling admissions, with offers extended weekly. Full process spans 3–5 weeks, fastest for standout candidates submitting polished portfolios upfront. Peak hiring hits Q1/Q3 aligned with product cycles.

Screening Methods

Lever ATS scans for keywords like "React hooks," "TypeScript," and "Next.js." Mandatory GitHub link; they check commit history and README quality. Video intros via Loom help remote applicants convey enthusiasm early.

Interview Preparation

Example Interview Questions

• "Walk us through optimizing a list of 10,000 encrypted records in React without lag."
• "How would you implement role-based UI access in a multi-tenant app?"
• "Describe a time you refactored a legacy component for better accessibility."
• "Build a real-time sync component using WebSockets and React Query."

How to Answer

Use STAR method: Situation, Task, Action, Result. For tech questions, think aloud—sketch on Excalidraw, explain trade-offs like useMemo vs. useCallback. Practice live coding on CoderPad, verbalizing keyboard inputs for clarity.

What Recruiters Evaluate

They gauge code cleanliness, security awareness (e.g., no hard-coded secrets), and scalability thinking. Cultural add: initiative in suggesting improvements during system design. Top criterion? Ability to ship production-ready code under ambiguity.

How to Get Selected

Practical Tips

• Tailor resume with quantifiable wins: "Boosted Lighthouse score 25% via lazy loading."
• Submit a 1-page case study of your best React project, metrics included.
• Network via LinkedIn—message Keeper engineers about their recent vault UI updates.
• Prep take-home by mimicking Keeper's style: TypeScript-first, test-driven.

Common Mistakes to Avoid

• Ignoring security: Forgetting input validation tanks credibility.
• Generic portfolios: No Keeper-specific demos like encrypted UIs.
• Rushing take-home: Untested, unstyled code screams inexperience.
• Poor remote presence: Mute off, eye contact via camera during calls.

How to Stand Out

Build a Keeper-inspired demo: React app with mock zero-knowledge vault using localStorage encryption. Share it on LinkedIn tagging Keeper's CTO. Reference their blog posts on PBKDF2 in your app story. Follow up post-assignment with a PR improving their sample code.
