About the Tooling team

We build apps that allow traders and data analysts to do their job efficiently. Our apps require a lot of work with large amounts of high-frequency data. The most important tools we build are for trading, data visualization, and configuration of internal systems. To keep up with the high quality of code, we’ve established regular code reviews and internal coding conventions. Our tech stack allows us to quickly build high-performing and reliable backend and frontend applications.

What will you do in the Tooling team

• 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.

• 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.

Your qualification

• Engineering Expertise: 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 we offer

• Salary + bonuses: Your total estimated annual compensation package includes a fixed salary and performance bonuses paid twice a year. The base salary ranges between €75k and €150k with no ceiling for highly-specialized and top 0.1% engineering candidates. Earning €150,000 in Slovakia can be an equivalent of earning €393,164 in London according to livingcost.org. due to low living costs and low income taxes in Slovakia, see below.

• Monthly fixed salary: We value specific expertise and offer above-the-market rates tailored to your experience and seniority level, adjusted to your local residency.

• Bonuses twice a year: We pay performance bonuses every 6 months. As an engineer, you can typically look forward to taking home between €40k and €70k annually, depending on your and the fund’s performance.

• Equity: You can opt to allocate a portion of your monthly salary toward equity in the company.

• Fund investment: As a member of our team, you have an opportunity to invest in our flagship multi-strategy fund that has annualized over 50% net returns since its inception in 2017. You can choose how much money you'd like to invest.

• Remote/Office: This role requires full-time onsite collaboration at one of our offices. Remote collaboration is negotiable for senior staff.

• Vacation: If you work full-time, you get 25 vacation days plus 12 public holidays each year, which totals approximately 40 days off per year (yes, that's A LOT!). If you need significantly more than that, you can arrange an unpaid leave with your manager and enjoy your sabbatical.

• Full-day catering: All-inclusive breakfast, lunch, afternoon snacks, fruits, and other treats in our offices save you hundreds of euros every month.

• Additional benefits include unlimited taxi to/from the office, mental health support, education & sports budget, cell phone plan in select countries, maternity leave, and more to boost your productivity.
