Software Engineer Intern

BlockTech is hiring Software Engineer Interns to join its engineering team in Singapore for summer 2027.

Over 12 weeks, you'll own a project end-to-end, with a real and direct impact on the business.

You'll work in a small team and see how a trading firm actually works from the inside.

About BlockTech

BlockTech is an algorithmic trading firm headquartered in Amsterdam, with a second office in Singapore. We specialize in market making and trade cryptocurrency derivatives and spot markets globally, using our own capital. We're growing fast and expanding into new markets.

We trade our own capital on systems that run 24/7 and have to be fast and correct without exception. Our systems run on Linux and are written in Rust and Python.

What will you do?

You will own a project from design to deployment, guided by experienced software engineers. It's a real project with a direct business impact, built on the same systems we trade on.

You will:

• Learn the markets. Start with a customized training program covering financial markets, the company, and your project.

• Own a project. Take it from design to deployment, guided by experienced software engineers.

• Work with production systems. Build on production-level data and systems, not a sandbox.

• Learn from the floor. Work with experienced engineers, traders, and researchers, and see how their work fits together.

What we're looking for

You'll need:

• To be in your penultimate or final year, studying computer science or a related discipline at a top university in Singapore.

• Availability to work full-time in Singapore for 12 weeks, starting May 10, 2027.

• Proficiency in a systems language (ideally Rust and/or C++) and working knowledge of Python.

• A solid grasp of data structures, algorithms, and what actually makes code fast.

• A critical mind that follows problems through to completion, high ownership, and clear communication in English.

Dates and location

• Duration: 12 weeks, starting May 10, 2027

• Location: On-site at our Singapore office, in the heart of the financial district (CBD)

• After the summer: the opportunity to convert into a full-time role after graduation, based on performance.

What else is in it for you

• A dedicated mentor, a cohort of fellow interns, and full-time colleagues to learn from

• An in-house training program and a close look at how engineering, research, and trading work together

• An environment that embraces AI, both to speed up your work and to advance our systems

• Regular socials and celebrations

• Daily breakfast and warm lunch, plus snacks and drinks all day

You'll be challenged from day one, with a mentor and a cohort of fellow interns around you. We promote reverse leadership, give everyone an equal playing field, and invest in personal and professional development.
