We continually refine, store, and analyze terabytes of data produced by market activity and our trading systems. Our user interfaces must present coherent, responsive real-time visualizations of market activity and system performance while providing intuitive control of a highly complex system. Our core systems must provide a stable, performant, and trusted foundation on which our systems are built\nYou'll build the Quantitative Research framework at the core of our systematic equities business. The framework models how trading strategies would behave against historical market data, allowing researchers to test ideas before they ever reach production. The same framework researchers use to develop and test new trading ideas is the one that powers production, meaning the systems you build have a direct impact on what the desk can research, deploy and trade.\nWorking alongside quant researchers and traders, you'll develop the tools, datasets and distributed systems that enable large-scale research across the cash equities markets in US, Europe and APAC. Every improvement you make helps the team evaluate new ideas and deploy them into production faster.\nWhat you'll do\nYou'll work closely with researchers and traders to build the software that underpins our systematic trading platform, from research through to production.\nYour work will include:\nDeveloping and extending the simulation framework used to research and run systematic cash equities strategies across ETFs and stocks.\n\nBuilding distributed systems that scale backtesting and model training across cloud and on-premise compute environments.\n\nCurating high-quality research datasets by combining live and historical market data into accurate, reproducible and scalable inputs for large-scale experimentation.\n\nWorking directly with researchers to understand new requirements and translate them into robust, production-ready software.\n\nImproving the tools and workflows that allow researchers to experiment, validate ideas and deploy strategies efficiently.\n\nApplying modern AI tools where they add value across the research and software development lifecycle.\n\nWho you are\nYou are a software engineer who enjoys solving complex technical problems and building systems that other engineers and researchers rely on every day.\nYou'll likely have:\nStrong Python development skills.\n\nExperience building simulation, backtesting or other large-scale computational frameworks. Experience in systematic trading, HFTor quantitative finance is a strong advantage.\n\nExperience designing and building large-scale, distributed or real-time systems.\n\nExperience using Python in research, data-intensive or analytical environments.\n\nStrong software engineering fundamentals and an interest in writing reliable, maintainable production code.\n\nThe following would also be beneficial:\nExperience with C++, particularly for performance-critical systems.\n\nExperience building data pipelines using technologies such as Spark, Polars, or Airflow.\n\nFamiliarity with cloud infrastructure or distributed compute platforms.\n\nAn interest in quantitative finance or systematic trading.\n\nWhat you'll get\nYou’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.\nIn addition, you’ll receive:\nA performance-based bonus structure unmatched anywhere in the industry. We combine our profits across desks, teams and offices into a global profit pool.\nThe opportunity to work alongside best-in-class professionals from over 50 different countries.\n25 paid vacation days in your first year, increasing to 30 from your second year onwards.\nTraining opportunities, discounts on health insurance, and fully paid first-class commuting expenses.\nExtensive office perks, including breakfast, lunch and dinner, world-class barista coffee, in-house physio and chair massages, organised sports and leisure activities, and Friday afternoon drinks.\nTraining and continuous learning opportunities, including access to conferences and tech events.\nCompetitive relocation packages and visa sponsorship where necessary for expats.\nWHO WE ARE:\nAt 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.
