Graduate Site Reliability Engineer

Optiver’s Site Reliability Engineering teams manage our live trading environment, which is active across 50+ global exchanges and hundreds of thousands of interconnected financial products. Our world-class infrastructure is a combination of vastly distributed systems, high-performance computing and low-latency trading algorithms, as well as high-throughput dataflows and data analysis.

To keep pace with the ever-changing markets, Optiver must always react with speed, and therefore takes an in-house approach to building, analysing, managing and improving our custom infrastructure. Taking this autonomy a step further, Optiver's huge volumes of data are stored at our own data centre rather than in the cloud. Our technological independence enables us to evolve our systems on a daily basis, operating with tight feedback loops and quick development cycles. The challenge is balancing innovation with reliability and performance in such a complex, time-pressured environment – and that's exactly where you come in.   

If you want to launch your career in a fast-paced, collaborative environment where your impact will be felt from day one, then Optiver is the place for you.

Who we are:

Optiver is a tech-driven trading firm and leading global market maker. As one of the oldest market making institutions, we are a trusted partner of 50+ exchanges across the globe. Our mission is to constantly improve the market by injecting liquidity, providing accurate pricing, increasing transparency and acting as a stabilising 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.

Our Amsterdam office is where it all began. Over 35 years ago, Optiver’s business started with a single trader on the floor of Amsterdam’s European Stock Exchange. Since our 1986 founding, Optiver’s Amsterdam office has grown into one of the most dynamic and exciting trading floors in Europe. Our culture reflects the Dutch capital city’s progressive, innovative and inclusive nature. With its unique spirit, Amsterdam is the ideal hub for our teams to trade a wide range of products from listed derivatives to cash equities, ETFs, bonds and foreign exchange. 

Our Systems:

At Optiver, engineering is at the core of our trading strategies. Trading is a complex and unpredictable environment with frequent changes and a high load. Our systems have to be fast, reliable and precise. Our engineers continually refine, store, and analyse hundreds of terabytes of data, enabling us to automatically price large, diverse sets of financial instruments with extremely low error tolerance. Our infrastructure is a combination of 10 000 highly customised components and 600 different applications, which run on 1500 servers distributed globally. We deal with 14 000 releases and 35 000 changes per year.

Reliability engineering at Optiver focuses on prevention and swift resolution of operational issues, guarding the reliability and performance of our systems. Reliability to us means having full control over our systems and guaranteeing proper functioning even in the most extreme market conditions. Simplicity and deterministic behavior are important aspects of reliability to us.

What you'll do:

As our Graduate Site Reliability Engineer, you'll be responsible for deploying, maintaining, monitoring and improving the reliability, scalability and performance of our in-house built trading systems. At Optiver, reliability means prevention and swift resolution across our software, to guarantee optimum functioning even in the most extreme market conditions. Having a decisive nature, engineering mindset and preference for simple solutions are essential to keeping our systems reliable. 

The Graduate Site Reliability Engineer role is crucial for Optiver's trading activities. Your scope will cover market access, monitoring and compliance, strategy evaluation and management, performance tuning and trading automation. Sitting in the middle of our buzzing trading floor, you will have constant face-to-face interaction with end-users (Traders and Researchers as well as fellow Engineers). This is an engineering role, not a support role, so you'll set the standards for our production environment. As part of our core business, you will make a real, direct impact on our ability to trade and trading results. No two days are the same in our high-stakes, flat-hierarchy environment.
