Full-stack EngineerVerified as a real position

Who we’re looking for

• Senior Engineering Expertise: 5+ years in system design, performance tuning, and UI development. Experience with TypeScript, React, and Node is an advantage.
• Strong Algorithmic Thinking: Analyze data and develop efficient solutions.
• Collaborative Spirit: Teamwork, communication, and collaboration are essential, as we work as a single unit, not as a group of individual contributors.
• Systems Thinking: Strong understanding of distributed systems, scalability, and performance optimization.
• Ownership & Problem Solving: We provide a lot of freedom to our engineers, so we expect you to be a “manager of one” who owns their agenda and delivers results.
• Culture Fit: Say things as they are, answer questions truthfully, leave ego at the door, challenge decisions when you disagree, and once a decision is final, commit and deliver your best.

What you’ll do

• There are performance challenges both at UI and on backend side, so you’ll take responsibility for improving UI and workflows for internal users such as traders and quants.
• Contribute to the development of internal tooling and new projects spanning frontend and backend technologies.
• Build apps that automatize certain workflows or processes (such as automatic fund transfers)
• Design and implement user-friendly applications using React, TypeScript, and Node.js.
• Work closely with stakeholders to understand requirements and deliver impactful solutions.
• Tackle complex challenges such as real-time trading platforms with autonomy and creativity.
