I'm working with a fast-growing proprietary trading firm in Amsterdam that is looking to hire an Experienced Quantitative Trader into its crypto HFT business.

The firm trades systematically across digital-asset markets using fully automated, high-frequency strategies and a low-latency trading platform.

• Identify new trading opportunities and market inefficiencies

• Backtest and validate quantitative ideas

• Monitor and optimise live strategies

• Investigate trading performance, execution and market behaviour

• Work closely with traders and engineers to move research into production

• Take meaningful ownership of strategies and trading decisions

What we're looking for

Essential:

• Master's or PhD in Mathematics, Physics, Computer Science, Engineering, Econometrics or another highly quantitative subject

Environment

This is a small, highly technical trading team where researchers, traders and engineers work closely together. It will suit someone who wants more strategy ownership and faster research-to-production cycles than they might get at a larger platform.

Over deze rol

Als data scientist bij Trading & Optimization werk je op het snijvlak van energie en AI, op een plek waar je werk direct effect heeft op het energienet. Jouw forecast om 13:00:00 stuurt om 13:00:01 een handelsbeslissing aan, en de impact zie je realtime terug op onze dashboards. Je bouwt niet één geïsoleerd model, maar een samenhangend geheel waarin probabilistische forecasting, optimalisatie en aansturing elkaar versterken. De feedbackloop is kort en meetbaar, wat je vandaag bouwt heeft snel impact.

Je werkt in een team waar data scientists, engineers en traders dicht op elkaar zitten. Er is weinig hiërarchie en veel ruimte voor eigen initiatief, maar ook duidelijke verwachtingen over eigenaarschap: jouw modellen draaien live en je bent zelf de eerste die ingrijpt als er iets misgaat. AI-tooling zoals Claude Code is volledig ingeburgerd en versnelt je werk. Zo draagt het team direct bij aan plan Zero: elke MWh die we slimmer verhandelen of efficiënter in een batterij laden of ontladen, is een MWh die niet uit een gascentrale hoeft te komen.

Wat wij bieden:

Dit krijg je van ons

• Een salaris tussen €4.000 en €6.000 bruto per maand, afhankelijk van je ervaring en senioriteit.
• 25 vakantiedagen (met de mogelijkheid om er meer bij te kopen) en reiskostenvergoeding.
• Een Claude Code Max 20x abonnement als secundaire arbeidsvoorwaarde. Je zet het in voor je dagelijkse werk en mag het ook gebruiken voor side projects en persoonlijke ontwikkeling.
• Een persoonlijk keuzebudget voor sport, boodschappen of iets anders dat bij je past.
• Vanaf dag één investeren we in jouw groei met de Zonneplan Academy, goede tools en ruimte om te blijven leren. Je kunt doorgroeien naar senior data scientist met specialisatie in energiehandel, batterij-optimalisatie of forecasting.
• Een pragmatische, no-nonsense werksfeer waarin korte lijnen de norm zijn. Je zit dicht op traders en engineers.

Sollicitatieproces:

Zo ziet het proces eruit

• 1. Solliciteer op deze vacature.
• 2. Telefonisch kennismakingsgesprek met Samer (recruiter).
• 3. Eerste gesprek met Maarten (direct leidinggevende van de functie) en iemand van het team.
• 4. Persoonlijkheids- en capaciteitentest, gevolgd door een technische casus met iemand van het team waarin je laat zien hoe je van data naar een forecastingmodel en businessimpact komt.
• 5. Is er een match? Dan doen we je snel een aanbod.

Klaar om jouw modellen in te zetten voor plan Zero?

Solliciteer direct. Heb je vragen? Bel of mail met Samer, 088 020 3012, samer.elmokdad@zonneplan.nl.

Samen bouwen aan de energie van morgen

Bij Zonneplan werken we aan één duidelijk doel: een Nederland zonder fossiele energie. Wij noemen dat plan Zero. Geen uitstoot, geen verspilling, geen afhankelijkheid. Dat klinkt groot, en dat is het ook. Maar jouw werk als data scientist brengt dit doel meetbaar dichterbij. Elke MWh die jouw modellen slimmer verhandelen of efficiënter in een batterij laden of ontladen, is een MWh die niet uit een gascentrale hoeft te komen. Jouw forecasts zorgen ervoor dat klanten worden beloond voor hun groene stroom en dat het energienet stabieler en schoner wordt. Samen zetten we stappen naar een toekomst waar iedereen trots op kan zijn.

Vereisten:

Dit neem jij mee

• Je hebt minimaal 3 jaar ervaring als data scientist en sterke fundamenten in statistiek en machine learning, met aantoonbare ervaring in forecasting of time series.
• Je schrijft Python op productieniveau en hebt ervaring met het deployen en monitoren van modellen in een live omgeving.
• Je hebt ervaring met of affiniteit voor AI-ondersteund ontwikkelen, bijvoorbeeld met tools als Claude Code, GitHub Copilot of vergelijkbare AI-assistenten.
• Je denkt vanuit commerciële impact: je kunt de stap maken van een goed model naar meetbare euro's en onderbouwt je keuzes met data.
• Je neemt eigenaarschap over wat je bouwt. Jouw modellen draaien live en je bent de eerste die ingrijpt, optimaliseert of bijstuurt wanneer dat nodig is.
• Je bent nieuwsgierig en proactief: je volgt ontwikkelingen in AI en machine learning op de voet en vertaalt die naar concrete experimenten en kansen.
• Je spreekt de Nederlandse taal op professioneel niveau.
