Fuel Oil Commodity Owner

This role can be based in either London or Singapore.

Fuel oil constantly surprises traders with its outsized moves. The question is whether you see it before everyone else does. Sparta is building the data platform that fuel oil and feedstocks traders, analysts and commercial teams use to make faster, better decisions. We cover forward curves, price assessments, market intelligence and trade flows across the global energy complex, and Fuel Oil is one of our most technical verticals. We're looking for someone to own it.

This role is an opportunity to own a vertical, build your profile, and be genuinely central to the direction of the business.

This role is an opportunity to own a vertical, build your profile, and be genuinely central to the direction of the business. We want someone who knows heavy product markets deeply and who is not afraid to build new things. Our Fuel Oil vertical already runs on market-leading tools and you will take them even further.

The role

This isn't an analyst position or a support role. It's the chance to become Sparta's primary Fuel Oil voice, internally and externally, and to shape what we build for the vertical.

You'll sit at the intersection of commercial, product, and market expertise. You'll be the internal and external authority on Fuel Oil: responsible for the health, growth, and strategic development of the vertical, while acting as a key face to clients on complex and technical engagements.

You'll need to be equally comfortable deep in the market microstructure of Fuel Oil — cash differentials, arbitrage dynamics, blend economics, price relationships across bunkering, power generation and feedstocks — as you are presenting to senior client stakeholders, shaping the product roadmap, being the market authority on the most opaque part of the oil barrel, and harnessing the power of AI to turn your knowledge into the next generation of advanced tools for fuel oil trading.

The role reports to our Head of Commodities.

What you'll do

Fuel Oil vertical ownership and strategy (~35% of role)

Own the Fuel Oil vertical end to end: its commercial performance, data integrity and strategic direction

Serve as the internal advocate for fuel oil and feedstocks across product, sales, engineering and research teams

Define and prioritise the Fuel Oil product roadmap with the product and technology teams

Act as the primary subject matter expert for all Fuel Oil decisions across the business

Building tools, models and AI agents (~25% of role)

Design and build Sparta’s next generation of heavy products analytical tools and pricing models

Own the fuel oil knowledge base behind our AI products: write the domain rules, test answers against desk judgement and catch errors before clients do

Prototype quickly with AI coding tools, then work with engineering to ship the ideas that work

Client interactions and technical demos (~15% of role)

Lead complex, discovery-focused and technical client conversations and demos

Support sales and account management on senior or strategically important Fuel Oil and Feedstocks opportunities

Represent Sparta at industry events, conferences and client visits as a Fuel Oil and Feedstocks expert

Market commentary and content (~15% of role)

Take editorial ownership of Fuel Oil market commentary and content

Define the voice and analytical framework for Fuel Oil commentary across client-facing and marketing channels

Work with analysts and contributors to keep output accurate, well argued and commercially relevant

Process and data quality (~10% of role)

Oversee the operational processes behind the vertical: cash differential modelling and uploads, component premiums and landed diffs, new arbitrage routes and price points, blend hub coverage, and ongoing data quality

Build scalable processes and delegate or automate routine tasks where it makes sense

What we're looking for

Required

Deep Fuel Oil & Feedstocks market expertise — strong working knowledge of fuel oil benchmarks, differentials, blending economics, arbitrage mechanics, refinery economics, and global heavy products flows.

Proven experience in a commodity-facing role within energy trading, data/analytics, financial services, or a closely related field

Hands-on building experience: working knowledge of Python and SQL (or equivalent) and a track record of tools or models other people actually use

Practical experience with AI tools such as LLMs, coding assistants or agents, and good judgement about where they get the market wrong

Ability to turn market complexity into clear product requirements, specifications engineers can build from, and client value propositions

Confident and credible in client-facing settings, including technical discovery calls and senior stakeholder presentations

Strong written and verbal communication, with experience producing or overseeing market commentary

Comfortable working across sales, product, technology and research teams

Desirable

Experience with pricing, data, or analytics platforms in the energy space

Familiarity with fuel oil data operations: cash differentials, landed diffs and price curve maintenance

Experience shipping work to production alongside an engineering team (version control, code review)

Existing network within the Fuel Oil & Feedstocks trading community

What success looks like

In your first six months, you will have:

Taken full ownership of the Fuel Oil vertical and its operational processes
