Profile match
Optiver is a Dutch proprietary trading firm founded in 1986 and headquartered in Amsterdam. It builds ultra-low-latency trading systems and hardware to provide liquidity on exchanges worldwide. The company is one of the largest technology employers in Amsterdam despite trading only its own capital.

Optiver leverages technology to solve a variety of complex problems: optimising for scarce bandwidth, responding to market events with nanosecond speed, automatically pricing complex sets of financial instruments with extremely low error tolerance, and analysing huge volumes of data. Our systems are built to add to the stability of the market, not detract from it; therefore they must operate at peak efficiency in the most extreme market conditions. To achieve this, our user interfaces must present coherent, responsive, real-time visualisations of market activity and system performance while providing intuitive control of a highly complex system.  

Our Core Software Engineers focus on the infrastructural and strategic components of our software landscape, ensuring the core elements provide a stable, performant, and trusted foundation upon which our systems are built.

WHAT YOU'LL DO:

Our systems play an essential role in everything we do in the trading domain. That is why our Technology and Trading Teams collaborate closely to jointly explore ideas and establish the new directions. Together, they build and maintain an outstanding suite of reliable, high-performing systems and applications.

As a member of the Core Software Team:

  • You will provide the rock-solid software backbone on which the business relies every single day, and will define the technical arena in which the trading-focused development teams continue to innovate.
  • You will not only be challenged on your technical knowledge and skills, but also on your capacity for producing simple and elegant solutions in face of an incredibly fast-paced and ever changing business environment.

WHAT YOU'LL GET::

You’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers. Motivated by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, working collectively to tackle the toughest problems in the financial markets.

In addition, you’ll receive:

  • A performance-based bonus structure unmatched anywhere in the industry. We combine our profits across desks, teams and offices into a global profit pool.

  • The opportunity to work alongside best-in-class professionals from over 40 different countries.

  • 25 paid vacation days and fully paid first-class commuting expenses.

  • Training opportunities and discounts on health insurance.

  • Extensive office perks, including breakfast and lunch, world-class barista coffee, sports and leisure activities, Friday afternoon drinks, and weekly in-house chair massages.

  • Competitive relocation packages and visa sponsorship where necessary for expats.

WHO YOU ARE:

  • A Software Engineer with a genuine and deep desire to write clean and correct code, combined with a strong interest in delivering architectural and strategic solutions, topped off with a considerable dose of realistic and sustainable pragmatism allowing you to simply get things done
  • 4+ Years of experience (doesn't require experience in Finance)
  • A solid grasp of computer science, knowing your algorithms, memory and concurrency models, CPU-architecture, operating systems and relational databases etc
  • As our main body of software is written in C++ and runs on Linux, you will either need to have extensive experience in this language and platform or be more than willing to learn on the job. Next to C++, we also extensively use Python, C# and other languages in Optiver, and you are therefore expected to be willing and able to learn new languages quickly
  • We are looking for both senior and junior brilliant minds. If you feel comfortable with the characteristics outlined above, we strongly encourage you to apply!

WHO WE ARE:

At Optiver, our mission is to constantly improve the market by injecting liquidity, providing accurate pricing, increasing transparency and acting as a stabilizing force no matter the market conditions. With a focus on continuous improvement, we participate in the safeguarding of healthy and efficient markets for everyone who participates. As one of the largest market making institutions, we are a trusted partner of 70+ exchanges across the globe.
