Optiver

Optiver describes itself as a research and technology driven trading firm whose models and systems price risk, execute trades and provide liquidity across global markets.

The market-making explainer defines the activity as continuously quoting both bids and offers for instruments, a source of liquidity for counterparties.

The 2025 annual report identifies Optiver Holding B.V. as the reporting entity; group-level financial figures should not be assigned to the Amsterdam or London internship offices.

Optiver's European trading page says its Amsterdam and London offices provide liquidity in equities, fixed income and FX options to institutional counterparties.

Global risk and compliance teams are described as working with trading, research and technology on financial and operational risk.

An Optiver engineering account organises its trading systems around pricing, risk management and execution. This describes its internal framing, not proof of unique technology.

Optiver says its strategic investment portfolio includes market infrastructure, data and connectivity firms; the portfolio complements its own trading business.

The engineering account connects real-time execution systems to pricing models and risk systems, showing where model accuracy, latency and operational reliability interact.

An Optiver technology article describes expanding models, exchanges, products, data and compute capacity as a central machine-learning scaling problem.

Optiver's trading internship programme page describes building Python strategies against historical data, with systematic options and futures projects as examples; the page does not guarantee a particular Amsterdam assignment.

Optiver reported €1.769 billion of 2025 net profit attributable to equity holders; this is a group result, not an intern-team measure.

Optiver reported €4.556 billion of 2025 net trading income, a separate measure from net profit.

Optiver's 2025 review says it opened a New York office and expanded US trading into new asset classes.

The same review describes investment in artificial intelligence, data and compute as a technology priority.

Optiver attributes its 2025 financial performance partly to market conditions and partly to execution; the year-on-year result alone cannot isolate a sustainable trading edge.

Optiver lists stress testing, limits and real-time oversight among its trading exposure controls.

Optiver's official vacancy page captured on 24 September 2026 lists a 2027 quantitative trading internship in Amsterdam; the trading internship index also lists Amsterdam among 2027 openings.

The current Amsterdam vacancy describes a ten-week quantitative trading internship.

The Amsterdam description includes simulated trading sessions and projects linked to live trading questions.

The Amsterdam quantitative-trading posting asks for penultimate-year STEM students able to start full-time after graduation in 2028; Python experience is a plus rather than a stated requirement.

The Amsterdam posting asks candidates selected for the next stage to complete online assessments within seven days; it also states an eight-month reapplication restriction after assessment or interview for a quantitative graduate or internship role.

A separately captured 2027 Software Engineer Internship vacancy is in London and under Technology.

The separate London 2027 Software Engineer Internship vacancy says applicants must have UK work rights for the internship and that Optiver will not provide immigration support for this role.
