Overview

This internship is for students who want to solve real engineering problems and take full ownership of their work.

You’ll work on carefully scoped projects, building high-quality internal systems and tackling challenges that require thoughtful design and iteration.

You’ll be expected to understand the problem deeply, implement solutions, and refine them based on feedback from senior 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.

About Wincent

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

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

• Made Bratislava the central hub, not London or Amsterdam
