Software Engineer - Full-stack / Tooling Team

As a Software Engineer on Wincent's Tooling team, you will build powerful full-stack applications that empower traders and data analysts to perform at their best. You'll work on systems that handle massive streams of high-frequency data, supporting real-time trading, data visualization, and the configuration of complex internal systems. Your code will drive speed, precision, and insight across the trading ecosystem within minutes of deployment.

What you'll do

• Take responsibility for improving UI and workflows for internal users such as traders and quants, addressing performance challenges on both frontend and backend.
• Contribute to the development of internal tooling and new projects spanning frontend and backend technologies.
• Build applications that automate workflows and 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.

What you bring

• 5+ years of experience in system design, performance tuning, and UI development.
• Experience with TypeScript, React, and Node.js.
• Strong algorithmic thinking and the ability to analyze data and develop efficient solutions.
• A deep understanding of distributed systems, scalability, and performance optimization.
• Ownership mindset: you manage your own agenda, own your work, and deliver results independently.
• Collaborative spirit with strong teamwork, communication, and the ability to work as a single unit rather than individual contributors.
• Transparency and directness: you 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 fully.

What we offer

• Competitive base salary of 80,000-150,000 EUR per year, tailored to your expertise and seniority, with potential for higher packages in exceptional cases.
• Performance-based bonus paid every six months, tied to individual excellence and the fund's overall performance. In exceptional cases, engineers have earned more than 50% of yearly total compensation in bonuses.
• Equity in the company, allowing you to share directly in success.
• Opportunity to invest in Wincent's flagship multi-strategy fund, which has delivered up to 50% annualized net returns since 2017.

• Unlimited paid vacation and flexible working time.
