As a Software Engineer Intern at Optiver, you’ll work alongside experienced engineers to develop innovative solutions that enable us to respond to the financial markets at lightning-fast speeds.
Kickstart your learning in our renowned training program, where you’ll learn the fundamentals of trading and complete a C++ Developer course. Then, you’ll apply this knowledge in an impactful project that solves real-world challenges. In just a few weeks, you could develop latency-critical applications that contribute towards our trading success.
By the end of the 12-week internship, you’ll have deepened your understanding of how technology is used in the quantitative trading industry. Plus, if you’ve excelled over the summer, you’ll receive an offer for a return internship and/or as a Graduate Software Engineer.
What you’ll do
Led by our in-house education team that consists of ex-traders and engineers, you’ll delve into advanced engineering concepts and lead innovative projects, during our world-class training program. Whether it's developing ultra-low latency exchange protocol encoders and decoders, or fine-tuning our automated trading strategies and pricing models, you’ll work closely with traders and other engineers to build simple, well-architected solutions that meet the needs of our business.
You’ll experience the excitement of a fast-paced development cycle – owning a tight feedback loop, testing and shipping your code to production. You could be working on a change to a trading system in the morning and see it run live by the afternoon. No two days are the same, and it’s up to you and your team to drive our success in the ever-evolving capital markets.
Aside from technical skills, our education team will also work with you on your development, including:
- Workshops on a variety of tech-based topics, along with soft skills to support your holistic growth as an engineer.
- A dedicated mentor who will guide you through our development process and how our trading systems work.
- Trader training to get you up to speed on our business. This helps you understand the fundamentals of trading, enabling you to make an impact from the early stages of your Optiver career.
