We are looking for a Senior Python Engineer to join our Gas, Power & Renewables (GPR) Technology team. You will be a core member of a small, high-impact engineering group embedded within a broader team of quants, analysts, traders, and deal desk professionals. Your primary focus will be building risk solutions for the Power and Gas trading desk on top of Beacon Platform. This is a 100% hands-on development role — you will own the full development lifecycle, from capturing requirements directly with traders and stakeholders through to delivering production-quality solutions. This role will work directly with the trading desk. Candidates who have previously worked in a trading floor environment will be familiar with the pace and communication style, and will have a natural advantage. What You Will Do • Design, build, and maintain risk and analytics solutions for the Power and Gas desk using Python on top of Beacon Platform • Integrate quantitative models developed by the quant team into Beacon and connect them to relevant market data sources • Work in a fast-paced trading environment where decisions are made quickly and feedback is direct • Engage directly with traders, quants, analysts, and the deals desk to gather requirements, understand business needs, and present technical solutions • Collaborate with other Beacon engineers within the team to ensure consistency, code quality, and shared best practices • Contribute to the ongoing evolution of the GPR technology stack What We Are Looking For Technical Skills • Strong Python development skills • 2+ years of hands-on development experience on Beacon Platform, Quarts, or Athena; candidates with SecDB development experience will also be considered • Solid understanding of quantitative modelling concepts — you will not be building models yourself, but you will be integrating them and need to understand what they do • Experience with Apache Kafka is a plus Domain Knowledge • Good knowledge of commodities markets, with a preference for US power and gas (both physical and paper) • Familiarity with instruments such as heat rate options, gas storage products, PPAs, and tolling agreements is highly desirable Soft Skills • Confident and resilient under pressure — comfortable receiving direct, candid feedback and using it constructively • Comfortable engaging with non-technical stakeholders — traders, analysts, and deal desk — to translate business requirements into technical solutions • Able to present and explain technical approaches clearly to a mixed audience • Self-sufficient and delivery-focused; this is not a role with heavy management oversight Key Relations and Reporting Structure Reporting Line • Reports directly to the Global Head, Gas, Power & Renewables Technology
