Quant & Trading Support

Wincent is a team of 150 Engineers, Traders, and Quants building systematic trading strategies across global markets, with roots in crypto and growing footprints across other asset classes. We handle ~1% of global crypto trading volume today, but both our ambitions and the tooling we build extend well beyond a single market.

We are a little weird.

• Our founders are self-taught; we didn’t grow up in the traditional HFT world.

• We chose no VCs, so ownership belongs to colleagues who build the company.

• We made Bratislava our home base, not London or Amsterdam.

• We believe that when you do something you love, it doesn’t feel like work. At Wincent, work is supposed to be purposeful, challenging, and deeply fulfilling.

• Integrity is not negotiable. Handshakes matter. We aim to be the good guys in the market.

• Money matters, but not more than our principles.

• We say things as they are. No fluff. No politics. No games.

• We trust each other. We practice radical transparency in compensation, bonuses, and even trading strategies, because trust compounds over time, both intellectually and financially.

We are looking for a Quant & Trading Support teammate who operates at the same seniority and trust level as our Quants and Traders, but with a different focus.

This role is about diligent ownership of production and trading operations, not creative strategy research. Your mission is to make sure the machine runs cleanly, predictably, and transparently, so that Traders can focus on tough decisions and Quants can focus on improving strategies.

You will sit with Quants and Traders, understand the context behind strategies, monitor their behavior in production, and take ownership of everything around trading, including: performance monitoring, dashboards, data visibility, exchange coordination, and operational follow-through.

This is a role for someone smart, reliable, and precise, who doesn’t drop the ball. You do not need to be creative or ambitious in the alpha-generation sense. You do need to care deeply about correctness, trust, and outcomes.

• Take ownership of production trading operations and day-to-day health of live strategies

• Monitor trading performance, PnL, risk metrics, and execution behavior across venues

• Investigate anomalies and deviations, communicating your findings clearly to Traders and Quants

• Build, maintain, and improve dashboards and monitoring tools by:

  • Writing queries

  • Creating clear, reliable data visualizations

  • Ensuring the right metrics are visible at the right time

• Maintain oversight of exchange changes (APIs, rules, fees, behavior) and coordinate communication with exchanges

• Act as a first line of defense when things behave unexpectedly

• Ensure research, production, and reality stay aligned through careful validation and follow-up

• Document issues, resolutions, and learnings for future robustness

This is not a junior support role. We are looking for someone who is:

• Diligent: detail-oriented, careful, and consistent

• Smart: strong analytical thinking and ability to understand complex systems

• Comfortable operating with context, not just checklists

• A clear and reliable communicator (especially when things go wrong)

• Calm under pressure and structured in problem-solving

Must-Haves

• Strong quantitative background

• Baseline coding ability (Python preferred) to analyze data, write queries, and build tooling

• Experience or strong interest in trading systems, market data, or production environments

• Ability to work independently and take full ownership of your domain

• Based in Bratislava as this is a trust-heavy, in-person role

Nice-to-Haves (Not Required)

• Experience in trading support, quant ops, or live trading environments

• Familiarity with crypto exchanges and market microstructure

• SQL, time-series analysis, or dashboarding / building BI tools

• Prior exposure to production systems where correctness matters

At Wincent, we foster a culture of transparency, ownership, and autonomy, where every team member is empowered to make a meaningful impact. We prioritize clear objectives and give you the freedom to innovate and grow within a supportive, high-performing environment.

We value exceptional TOP 1% talent over a perfect match to a job description. If our vision and values resonate with you, we’d love to hear from you. Don’t hesitate to reach out—let’s explore how you can be part of shaping the future of cryptocurrency trading with us!
