Your success story starts here...

THE ROLE

We're hiring a Commodity Derivatives Structurer / Quant who is equally at home structuring a deal and further developing the pricing and risk library behind it. Roughly half your time goes into structuring and pricing live transactions with the desk. The other half goes into building out our front-office pricing library: the models, data infrastructure and tools the team relies on every day. You'll sit directly in the front office, working closely with traders and originators.

WHAT YOU'LL DO

Deal pricing and structuring

• Price complex and non-standard structures: structured offtakes, options and embedded optionality on physical and environmental commodities.
• Build and challenge deal models covering valuation, risk, counterparty credit exposure and funding costs.
• Support originators and traders in commercial negotiations with clear pricing rationale and scenario analysis.
• Hand deals over cleanly to risk, middle office and finance, with documented methodology.

Front-office pricing library

• Design, implement and extend the team's pricing library: curve and vol fitters, pricing engines, simulation and exposure/xVA calculations.
• Build and maintain the data layer behind it: market, transaction and reference data in our databases.
• Write production-quality, tested and version-controlled code that others on the desk can use and trust.
• Turn one-off spreadsheet models into robust, reusable tools.

WHAT YOU BRING

• 2+ years of professional experience in a trading environment (trading house, utility trading desk, bank or fund), in a front-office quant, structuring or pricing role, ideally with exposure to pricing illiquid or OTC products.
• A firm grasp of derivatives pricing: forward curves, options and volatility, Monte Carlo methods, and credit/counterparty risk concepts.
• Strong programming skills in Python, writing maintainable, tested code with version control (Git).
• Solid database knowledge: SQL, data modelling and building reliable data pipelines.
• Commercial judgement: you understand why a deal makes money, not just how to value it.
• An outstanding work ethic: you take ownership, follow through, and step up when a deal is in closing territory.
• A degree in a quantitative discipline (mathematics, physics, engineering, computer science, quantitative finance or similar).
• Clear communication in English, with traders and with non-technical stakeholders.

NICE TO HAVE

• Experience with energy, emissions or other environmental commodities (RECs, biofuels, biomethane, EUAs, etc.)
• Experience with CVA/xVA, repo or structured financing transactions
• Familiarity with C++, cloud infrastructure or ETRM systems
• Additional languages (e.g., Dutch, German or Spanish)

WHAT WE OFFER

• A front-office seat with direct impact: your models price real deals, and you'll help shape how the desk's tooling evolves
• A small, senior team with short decision lines and real ownership of what you build
• Exposure to fast-growing markets at the intersection of energy transition and finance
• A competitive package (salary and bonus) based on experience
• Based in Amsterdam

DIVERSITY STATEMENT

We encourage and welcome applications from candidates of diverse backgrounds, experiences, and perspectives to enhance our team and contribute to a more inclusive work environment. Diversity, inclusion, and belonging are more than just concepts. They are part of our everyday work culture, ensuring employees feel welcomed and build meaningful connections.

At STX, we ask applicants to think holistically about roles. If the roles sounds exciting and a great fit for you, but some of the criteria or required experience doesn't 100% line up, we still encourage you to apply!
