HFT Performance Engineer

About us

Imagine building systems that think in microseconds — algorithms that move millions with absolute precision.

We’re engineers driven by performance, reliability, and meaningful innovation in the crypto trading space. Our team — experienced builders from Amazon, and Google, with academic backgrounds from Berkeley, Caltech, ETH, and MIT — is developing a next-generation trading platform that executes orders seamlessly across 10+ exchanges and dozens of tokens.

Here, every line of code matters. Push your work to production, and within minutes it could be driving thousands of trades per hour. It’s fast, impactful, and never dull — the kind of engineering challenge that keeps you sharp and inspired.

About the Performance team

Our team is dedicated to optimizing the performance of the full trading system — from hardware to software. Our guiding principle is simple: reduce latency, improve reliability, and make the entire trading pipeline faster and more efficient.

We work on everything from kernel-level debugging and network stack tuning to market data feed handling and real-time system metrics. This involves performance profiling, hardware benchmarking, and creating tools for trace analysis and monitoring.

Our engineers analyze live production data, prototype system changes, and collaborate with teams across trading, infrastructure, and software to ensure consistent performance improvements.

What will you do in the Performance team

• Optimize trading system performance – Improve latency, reliability, and efficiency across the full trading stack (hardware, network, and software).

• Analyze and tune low-level systems – Perform kernel-level debugging, network stack optimization, and hardware benchmarking to enhance system speed.

• Monitor and profile live trading systems – Collect and analyze real-time performance data, create monitoring tools, and identify bottlenecks.

• Prototype and implement performance improvements – Test new ideas, optimize configurations, and deploy enhancements in live trading environments.

• Collaborate across technical teams – Work with trading, infrastructure, and software engineers to ensure consistent, measurable system improvements.

What we expect from you

• Senior Expertise (5+ years) with low-latency hardware and software

• Strong background in Kernel Linux, Network Engineering, and Deep Network Knowledge.

• Understanding of market data feeds, order books, and exchange-level protocols.

• Experience with performance testing tools and scripting.

Compensation, work arrangement, and benefits

• We offer competitive, above-market compensation tailored to your expertise, seniority, and local residency. The typical base salary range is 80,000 € – 150,000 € per year, with the final offer reflecting each candidate’s individual experience and depth of technical skill. We can go even higher on base salary in specific cases.

• Every six months, we celebrate impact. This bonus is tied directly to both individual excellence and the fund’s overall performance. When the team wins, you win too. In some exceptional cases, our engineers could get more than 50% of yearly total compensation in bonuses,

• At Wincent, equity is a part of your compensation package, letting you share directly in the company’s success — when the firm wins, so do you. The equity fund is being regularly reevaluated and has a permanent upward trajectory.

• Fund Investment: As part of our team, you’ll have the rare opportunity to invest in our flagship multi-strategy fund, which has delivered up to 50% annualized net returns since 2017. You decide how much you want to invest — it’s your chance to grow alongside the firm’s success.

• Onsite vs Remote: We prefer onsite collaboration in Bratislava (we are more than happy to provide relocation support if needed). However we are also open to remote work, giving you the freedom to work from anywhere. We only ask for two types of “in-person touchpoints" — a 2-week onboarding at the start and quarterly visit to Bratislava, Slovakia.

• Vacation: We believe great work comes from a balanced life. We have flexible working time and we also offer unlimited paid vacation.
