Engineers - Internship 2026

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.

About Wincent

We are a team of 150+ people, primarily Engineers, Traders and Quants, focused on HFT with ~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 cap-table; this spot is for our colleagues

• Made Bratislava the central hub, not London or Amsterdam

Culture

When you do something you love, it does not feel like work. At Wincent work is purposeful and fulfilling.

Integrity is not negotiable
Handshakes are sacred for us. Being in the money making business is good, but that alone is not worth our soul; we follow the motto “Be the good guys in the market”.
