Overview

This internship is for students who want to spend a summer doing real engineering work inside a production trading environment. Interns join one of our engineering teams and ship code that runs in production. There is no shadow work and no sandbox projects.

You will work closely with senior engineers, get direct feedback, and own clearly scoped problems with real impact. We expect interns to think, implement, test, and iterate like full-time engineers.

What you will work on

Depending on team fit and background, interns are embedded into one of our engineering teams (Tooling, Algo, OTC, or Core Systems) and contribute to carefully scoped engineering projects.

Typical responsibilities include:

  • Designing and implementing high-quality internal software in a controlled environment

  • Tackling clearly defined, non-trivial engineering problems end-to-end

  • Prototyping and validating new technical ideas and approaches

  • Studying existing systems and delivering focused, well-reasoned improvements

  • Engaging in code reviews and technical discussions with experienced engineers

This is not a research internship and not a learning-only program. You are expected to deliver working software.

What we expect from you

  • Strong fundamentals in computer science (algorithms, data structures, systems basics)

  • Hands-on programming experience outside of coursework (projects, competitions, open source)

  • Comfort working in Linux-based environments

  • Ability to reason independently and ask precise questions when blocked

  • Come up with ideas and solutions for vaguely defined open problems

  • Ownership mindset: you take responsibility for finishing what you start

Experience with Rust, Python, TypeScript, or systems programming is a plus, but not required.

Who this internship is for

  • Students in Computer Science, Software Engineering, Mathematics, or related fields

  • Candidates who are comfortable with open-ended problems and limited initial direction

  • Candidates who prefer low bureaucracy, direct feedback, and clear expectations

  • This internship is open to candidates in their final year of studies, with top-performing interns considered for a full-time position following the internship

Internship details

  • Duration: Summer 2026 (12 weeks)

  • Location: Bratislava preferred; relocation support available

  • Work mode: Onsite, working directly with the team

  • Compensation: 5,000 EUR / month which is an equivalent of earning €13,105 in London according to livingcost.org. due to low living costs and low income taxes in Slovakia, see below.

  • Conversion: Strong interns are considered first for full-time roles after graduation

Interview process

  • Online Coding challenge and Technical Quiz

  • Chat with a recruiter. Consider it an introductory call; there’s no need to prepare anything apart from your questions regarding the company, team, culture, and any work-related inquiries.

  • Technical interview. Live coding task followed by a discussion on experience and background.

We keep the process short and signal-driven.

Due to the high volume of applications we receive, for some roles we use Artificial Intelligence (AI) tools to help our recruiters review your application. In particular, we may use AI tools at the following stages of your application:

  1. CV Screening. We may use a tool that gives insights on how well your CV corresponds to the criteria for the role you applied for. These criteria are chosen by our recruiters, not AI. All insights are reviewed by a human, who takes the decision whether to pass your application through to the next stage individually. This improves outcomes by ensuring you receive a timely response to your application and that a recruiter does not miss relevant experience on your CV; and
  2. Interview Stage. With your express permission at the start of an interview, we may use a AI tool that transcribes the interview, which allows your interviewer to focus more on you instead of note-taking. We may also use an AI tool to provide a summary of the transcript so we can keep track of what was discussed, which helps later interviewers avoid repeating questions. A recruiter may take into account this transcript and summary in deciding whether to pass your application through to the next round.

We process applicant data in accordance with our Data Privacy and Processing Policy, which you can read here. If you have any questions about how we protect or process your data, please contact gdpr@wincent.co

Frequently Asked Questions

How long is the internship?

The internship lasts for 7 weeks. It begins in June and runs through the end of August, taking place fully on-site at our offices. This timeline is designed to give you enough time to work on meaningful projects while still fitting into a summer break.

No, we do not require previous trading experience. Our internship program is designed to teach you the fundamentals of trading and provide hands-on exposure to how markets work. What we value most are strong analytical skills, curiosity, and a willingness to learn. Many of our successful interns come from backgrounds in mathematics, computer science, or engineering, with no direct trading experience before joining.
Yes. We provide comprehensive relocation support to make your transition as smooth as possible. This includes covering your travel expenses and arranging fully paid accommodation for the duration of your internship. Our team will also guide you through the logistics of moving, so you can focus on learning and getting the most out of your experience.
Yes. We provide fully covered accommodation for the entire duration of your internship. Housing is arranged by our team so you don’t need to worry about finding a place yourself, allowing you to focus fully on the program.
Yes. As an intern, you’ll contribute directly to projects that have real impact on our trading strategies and operations. You’ll work alongside experienced traders and engineers, gaining hands-on experience with the same tools and data we use every day. Your work won’t be limited to simulations, you’ll see how your contributions fit into live projects and decision-making.
No. The internship is fully on-site in Bratislava. We believe that being physically present allows interns to learn faster, collaborate closely with traders and engineers, and experience our team culture firsthand. This setup ensures you gain the most from mentorship and real-time feedback.
Yes. High-performing interns may receive a return offer to join us full-time after graduation. Each year, we extend offers to some of our interns who demonstrate strong skills, curiosity, and cultural fit. The internship is designed to give you a real sense of what a long-term career with us could look like, and many of our current team members started as interns.
Return offers are extended to interns who demonstrate exceptional performance, strong problem-solving ability, and a good cultural fit during the program. Depending on your strengths and interests, you may receive an offer to join one of several paths—such as trading, quantitative research, or DeFi. The area of the offer is determined by the skills you showcase during the internship and where we see the best long-term match.

Our interview process is designed to test your problem-solving ability rather than prior experience in trading. We focus on probability, statistics, logical reasoning, and intuition, as well as your ability to think under uncertainty.

The process begins with an online assessment. Successful candidates are then invited to two technical rounds covering probability and statistics. The final stage is an on-site session in Bratislava, where you’ll participate in interactive betting games that simulate real decision-making scenarios.

For a detailed breakdown, please check our interview process.

We aim to get back to all applicants within one week of receiving the initial application. The exact timing can vary depending on the number of applications we’re processing at that moment, but you can expect a timely response and updates throughout the process.

The process typically involves four stages: an online assessment (with a two-week deadline), two technical interviews, and a final on-site round. After you submit your assessment, we schedule interviews as soon as possible based on interviewer availability.

From initial application to final decision, the timeline can vary, but in most cases it takes about one to three weeks. For exceptional candidates who progress quickly and have good scheduling availability, the entire process can sometimes be completed in as little as 10 days.

The application form is designed to be quick and straightforward, so it should take only a few minutes to complete. We keep the process simple to ensure you can focus on showcasing your skills and motivation rather than filling out lengthy paperwork.
