Sr. Front-End Engineer

As a Senior Front-End Engineer at BlackCloak, you will lead the development of high-quality applications using React and React Native. This involves collaborating with cross-functional teams, mentoring junior developers, establishing best practices and coding standards, as well as optimizing applications for performance and scalability. You’ll also implement automated testing frameworks to ensure the reliability of our applications.

At BlackCloak, we seek candidates with at least 5 years of professional front-end development experience. You should have a strong command of JavaScript/TypeScript, HTML5, and CSS3, alongside 3 years of hands-on experience with React and React Native. A solid understanding of RESTful APIs, state management libraries, and performance optimization techniques is also essential for success in this role.

BlackCloak boasts an extremely dynamic work environment that is 100% remote within the USA. We prioritize work-life balance and encourage teamwork through virtual events and occasional team off-sites. Everyone’s input is valued, fostering a culture of collaboration where you can contribute effectively while working from the comfort of your home.

As a Senior Front-End Engineer at BlackCloak, you’ll work extensively with modern front-end technologies including JavaScript/TypeScript, React, React Native, and various state management libraries like Redux and MobX. You’ll also engage with testing frameworks and be involved in CI/CD pipelines, ensuring efficient deployment and high code quality.

Absolutely! At BlackCloak, we emphasize continuous learning and professional growth. As a Senior Front-End Engineer, you’ll have opportunities to mentor junior developers, participate in knowledge-sharing sessions, and stay updated with the latest industry trends and technologies to enhance your skills and career trajectory.

Certainly! React is primarily used for building web applications, while React Native is designed for mobile application development. React allows you to create dynamic user interfaces for web applications that run in the browser, whereas React Native allows you to build native mobile apps for iOS and Android devices using the same React concepts.

To optimize performance in a React application, you can utilize techniques such as code splitting, lazy loading components, memoization with React.memo, and optimizing rendering with PureComponent or shouldComponentUpdate. Leveraging tools like the React Profiler can also help identify performance bottlenecks.

State management libraries in React, such as Redux, MobX, and the Context API, are used to manage and share application state across components efficiently. They help maintain a single source of truth for your application’s data, making it easier to manage state changes and side effects, especially in large applications.

Certainly! My experience with responsive design involves using flexible grid layouts, media queries, and responsive images to ensure that applications look great across all device sizes. Using frameworks like Bootstrap or CSS flexbox and grid can simplify this process, and I ensure to test across multiple devices to maintain user experience.

In my development, I prioritize accessibility by incorporating ARIA attributes, using semantic HTML elements, ensuring color contrast ratios are compliant, and enabling keyboard navigation. I also test applications using screen readers to ensure that they are usable by everyone, including users with disabilities.

When mentoring junior developers, I focus on creating a collaborative environment where they feel comfortable asking questions. I provide guidance on best practices and coding standards and give them opportunities to pair program and review code together, helping to instill confidence and accelerate their learning process.

In a recent project, we encountered performance issues that delayed deployment. I led the team in conducting a thorough performance audit, identifying bottlenecks, and implementing code optimizations like memoization and code splitting, which ultimately improved load times and user experience.

I stay updated with the latest trends in front-end development by following tech blogs, participating in online forums, enrolling in relevant courses, and attending webinars. Additionally, I contribute to and read open-source projects on GitHub to understand new practices and tools in the industry.

For testing React applications, I commonly use Jest as my testing framework along with React Testing Library for component testing. These tools allow for creating unit tests and integration tests effectively while ensuring that components behave as expected during various scenarios.

I have extensive experience with Agile methodologies, particularly Scrum. I actively participate in daily stand-ups, sprint planning, and retrospectives. Embracing Agile principles helps me and my team remain adaptive to changes and promote incremental development, ensuring we deliver value continuously.
