If you're prepared to commit, with grit, determination, and the drive to excel, then this is your calling.

Role Overview

Join us as a Frontend Engineer, responsible for crafting reusable UI components with minimal design guidance. You’ll play a hands-on role in shaping the user experience, bringing technical precision and strong UX instincts to an environment where scalability and thoughtful interaction matter.

• Translate product and interaction needs into intuitive frontend behavior.
• Collaborate with backend or AI/ML engineers to ensure cohesive end-to-end user experiences.
• Build frontends that scale robustly and anticipate evolving requirements.
• Exhibit ownership over frontend quality, performance, and usability.

Required Skills & Profile

• Proficiency in TypeScript and familiarity with Vite (or similar React-based tooling).
• Deep comfort with frontend architecture: component reusability, scalability, and interaction patterns.
• Strong UX intuition: you understand how design choices impact usability and can advocate for better patterns.
• Self-sufficiency: able to work with minimal oversight, proactively solve problems, and iterate independently.
• Emotional resilience to thrive in a high-pressure, unpredictable environment.
• A mindset focused on excellence: you believe you're among the top 1% in your craft.
• Proven track record of tangibly contributing to complex systems.

Why Watchtower Labs?

• Intense challenge, unparalleled growth: long hours and high stakes and in return, rapid personal and professional development.
• Impact and ownership: Your work directly influences critical systems and simulations.
