Senior Beacon Engineer Quant London Liverpool Street, EC2M 4TP

Company Overview

At RocketFin, we are a leading provider of innovative financial technology solutions, specialising in deploying cutting‑edge risk and trading technologies for some of the world’s most complex commodities operations.

Position Overview

We are seeking a Senior Beacon Engineer Quant to join a high‑impact programme deploying risk and trading technology for one of the world’s largest integrated energy companies — a global leader in oil, gas, renewables, and low‑carbon energy trading, operating across upstream, downstream, and trading divisions at massive scale.

This is an opportunity to work at the forefront of commodities risk technology, contributing to mission‑critical systems that underpin billion‑dollar trading decisions.

Responsibilities

• Lead Beacon development end‑to‑end — design, build, and maintain complex quantitative models, scripts, and workflows within the Beacon platform, covering risk analytics, P&L, Greeks, and mark‑to‑market across multi‑commodity portfolios.
• Quantitative modelling — develop and validate pricing models, risk metrics (VaR, sensitivities, scenario analysis), and structured trade lifecycle workflows within Beacon.
• Cross‑platform integration — leverage your Endur exposure to support integration touchpoints between Beacon and the broader ETRM ecosystem, ensuring data consistency and workflow alignment.
• Stakeholder collaboration — partner closely with front‑office quants, trading desks, risk managers, and technology teams to translate complex business requirements into robust technical solutions.
• Technical leadership — act as a senior voice within the engineering team, mentoring junior developers, setting coding standards, and championing best practices in Beacon development.
• Continuous improvement — proactively identify opportunities to optimise existing Beacon infrastructure, improve performance, and reduce operational risk.

Requirements

• Extensive Beacon experience — proven, hands‑on expertise building and maintaining solutions within the Beacon/OpenLink Beacon platform is essential.
• Quantitative background — strong grounding in financial mathematics, derivatives pricing, or commodities risk, with the ability to implement and validate quantitative models in Beacon.
• Endur exposure — familiarity with OpenLink Endur and ETRM workflows is a valuable plus, particularly around trade lifecycle, settlements, or risk reporting.
• Commodities domain knowledge — experience in energy, oil & gas, power, or related commodity markets is highly desirable given the client environment.
• Analytical rigour — strong problem‑solving capability with an ability to navigate ambiguity, debug complex systems, and deliver accurate, auditable outputs.
• Communication skills — comfortable engaging with both technical and business stakeholders, with the ability to articulate complex technical concepts clearly.
• Degree‑level education in a quantitative discipline (Mathematics, Physics, Computer Science, Engineering, Finance, or similar). A postgraduate qualification is advantageous.
