Chief of Staff to the COO

About Wincent

We are a team of 150+ people, primarily Engineers, Traders, and Quants, focused on high-frequency trading with around 1% of global crypto trading volume. Being a bit weird, we

• Are self-taught; our founders do not come from any of the big HFTs,

• Chose to have no VCs on the cap table; this spot is for our colleagues,

• Made Bratislava the central hub, not London or Amsterdam.

The role

This is a high-impact operator role at the center of the company. You are the COO’s closest partner and the person who makes sure strategy turns into execution. Your job is to create clarity, kill chaos, and push critical initiatives over the finish line.

We move fast, are not afraid of change, and are happy to deal with problems without having a clear playbook. You’ll need to take control in the face of ambiguity, think independently, and take full ownership of outcomes.

What you’ll own

• Execution of strategic projects and implementation of internal processes across multiple teams (including Trading Operations, Finance, HR, Legal and Compliance).. You won’t just track progress, you will drive it.

• Company operating rhythm including goal-setting, leadership check-ins, budgeting cycles, and follow-ups that actually result in decisions and action.

• Cross-team coordination and acting as the bridge between departments to remove blockers, avoid duplication, and keep everyone aligned.

• Process design and improvement by identifying where growth creates friction and building simple, scalable ways of working.

• Safeguarding COO’s time and focus by prioritizing what matters most, organising meeting agendas and tracking tasks.

• Increasing signal-to-noise ratio by distilling complex discussions, data, and Slack overload into clear takeaways and next actions.

• Briefings and preparation: ensuring the COO walks into every meeting fully informed, with context, data, and a clear narrative.

Who you are

• Fast-learner with a high clock speed and the ability to jump into new topics quickly

• A natural finisher who pushes things to completion

• Comfortable making decisions with incomplete information

• Highly organized and structured, with strong attention to detail

• Direct and clear in communication, no fluff, no politics

• Calm under pressure and able to coordinate responses when things go wrong

• Skeptical in a healthy way, you ask questions and dig deep

• Willing to go beyond a strict 9-to-5 when the situation requires it

Experience

• Background in operations, consulting, strategy, finance, or similar execution-heavy roles

• Experience working closely with senior leadership

• Proven ability to manage complex, cross-functional projects

• Exposure to regulated, fast-moving, or high-performance environments is a strong plus

What you’ll gain

• Huge amount of agency and trust from day one

• Direct exposure to senior leadership and decision-making

• The chance to shape how a top-10 global crypto trading firm operates

• A culture with low politics, high ownership, and radical transparency

• Work that is intense and meaningful, and impact is highly visible.
