You’ll work closely with senior engineers and product teams to deliver reliable, user-focused features, write clean and maintainable code, and contribute to ongoing technical improvements.

You’re not just executing tasks — you’re thinking critically about how things work, asking good questions, and growing your ability to solve complex problems independently.

Your passion for clean, efficient code is matched by your collaborative spirit—you thrive in cross-functional teams, where you contribute meaningfully to discussions and continuously learn from others. You're proactive, curious, and always looking for ways to improve user experiences, whether that means optimizing performance, refining data flow, or experimenting with new technologies.

• 5+ years of experience developing, deploying, and maintaining web libraries and frameworks with special focus on web security.
• Production-level application development experience using Node.js
