To thrive as a Mid Level Front End Developer, you need solid proficiency in HTML, CSS, JavaScript, and modern frameworks like React or Angular, typically supported by a relevant degree or practical experience. Familiarity with version control systems like Git, responsive design tools, and optionally certifications such as Microsoft Certified: JavaScript Developer add value. Strong collaboration, problem-solving abilities, and effective communication distinguish top performers in this field. These skills ensure that you can build user-friendly, high-quality web interfaces and work efficiently within cross-functional teams.
Mid Level Front End Developers spend much of their day coding and refining user interfaces based on project requirements and feedback from stakeholders. They regularly collaborate with designers and back-end developers to ensure seamless integration of visual and functional elements, as well as participate in code reviews to maintain high quality standards. Additionally, they often troubleshoot bugs, optimize page performance, and keep up with the latest web technologies to improve user experience. This role blends both independent problem-solving and teamwork in a dynamic, fast-paced setting.
A Mid Level Front End Developer is responsible for building and optimizing the user interface of web applications using HTML, CSS, and JavaScript frameworks like React or Vue. They collaborate with designers and back-end developers to ensure a seamless user experience. Typically, they have 2-5 years of experience and are expected to write clean, maintainable code while troubleshooting UI/UX issues. Additionally, they may contribute to component libraries, improve performance, and follow best practices in responsive design and accessibility.

Adhere to code guidelines and keep co-workers accountable for it as well
Ship code that is easy to read, maintain and debug
Be on top of all most recent code practices, libraries and frameworks and push the team to use better tools
Conduct thoughtful code reviews for your team members
3+ years of experience as a frontend developer
Proficiency in unit/integration testing
Good understanding of how to implement useful logging
The skill of documenting your own code (writing useful comments)
You iterate quickly with short feedback loops
You're comfortable with change and ambiguity and thrive working autonomously
English level - Intermediate or higher
Experienced using self-improvement apps (habit trackers, time management tools, fitness trackers, etc.)
Previous experience working at high growth start-ups
Previous experience working with distributed teams in different time zones
Previous experience building backends to support millions of users
