LNG Commodity Owner

We Are Sparta

Sparta is the AI leader for commodity trading, home to Leonidas AI, the first operating system for oil and commodity traders.

Backed by $42 million in Series B funding led by One Peak, with participation from returning investors FirstMark and Singular, the same investors behind AI leaders like Legora, Dataiku, and Synthesia. Most companies are building a chatbot on top of data. We've built an agent with an actual reasoning layer, grounded in years of proprietary market data and in-house trading expertise nobody else has.

We're scaling fast, and it's an exciting time to join. From independents to multinationals, the world's leading commodity teams use Sparta and Leonidas AI to move faster, trade smarter, and stay ahead of the market.

At Sparta, you'll be trusted to take ownership, backed by a team who wants you to succeed. AI is how we build here, not just what we sell. Good ideas move fast, and yours could go from staging to production in a couple of hours, whatever department you're in. You'll be challenged, supported, and given room to grow, building the AI that's changing how commodity trading gets done.

Your work has reach. From shaping Leonidas AI, to powering smarter decisions for traders around the world, to changing how commodity trading is done. And because we're growing fast, you'll accelerate your career with a level of ownership and impact you simply won't get at bigger, slower-moving companies.

LNG Commodity Owner, Sparta Commodities

Singapore, Geneva or London

LNG moves on netbacks, shipping and a handful of hubs that rarely agree with each other. Plenty of people write about that. We want the person who builds the system that connects all the pieces of the puzzle, and then puts it in front of traders and makes it sell.

Sparta is building the data platform that energy 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. LNG is our next vertical, and we want an exceptional builder to lead it.

The role

This is a builder's seat. It isn't just an analyst position, a sales role or a thought-leadership seat. You will be leading the development of Sparta's LNG offering, from the first netback model to the AI analyst that puts together a forward view on LNG markets autonomously, working with our engineering, product, data and commercial teams. You will set the direction and stay hands-on: prototyping, testing and shipping with the team, not handing over a spec and waiting. Building on its own is not enough. The job is to build a product LNG desks will pay for, which means time with clients is as much a part of the role as time in the code.

We are looking for someone who knows LNG deeply: JKM, TTF and Henry Hub relationships, netbacks and delivered economics, shipping and regasification costs, cargo arbitrage between basins and contract structures. Your job is to turn that knowledge into products. Expect a good part of your week to be hands-on with AI coding tools: prototyping a pricing model in Python, standing up a data pipeline, creating market-leading knowledge graphs that an AI agent follows and testing its answers against desk judgement. The rest goes on working with engineers to harden, scale and ship what the team builds.

The role reports to our Head of Commodities.

What you'll do

Building products, data pipelines and AI agents (~55% of role)

• Lead the design and build of Sparta's LNG product set: netbacks, arbitrage routes, delivered price curves and the analytical tools that sit on top of them

• Build the LNG expert inside Leonidas with our AI engineers: the tools it calls, the domain rules it follows and the knowledge base behind them

• Build automated products with the team: a daily LNG brief autonomously written by AI analyst, alerts on the curves and spreads that matter, and the quality checks that catch errors before clients see them

• Build evaluation sets that test the AI against desk judgement, and keep them passing as the product changes

• Build the data pipelines behind the vertical with data and engineering colleagues: price inputs, freight and regas assumptions, vessel and terminal data, route onboarding and automated data quality checks

• Ship to production with engineering through our normal process (pull requests, code review, tests, CI), and hold the bar on scale, security and reliability

Owning the LNG vertical (~25% of role)

• Own the LNG vertical end to end: what we build, how well it works and how it performs commercially

• Set and sequence the LNG roadmap with product and technology, so clients get something useful early and more every few weeks

• Write the rules: the LNG conventions, definitions and desk judgement that every Sparta product and agent follows

• Lead the people working on LNG across product, engineering and data: set priorities, unblock them and raise the bar on quality

• Be the person the business comes to for any LNG decision

Building a product clients pay for (~20% of role)

• Lead discovery conversations and technical demos with LNG trading desks, analysts and commercial teams, and use what they tell you to decide what to build next

• Work with sales and account management on the first LNG deals and on adding LNG to existing oil and freight accounts: you bring the market credibility and the product, sales runs the commercial process

• Give sales a clear account of what the product does and why a desk would pay for it, so they can sell it without you in the room

• Represent Sparta at industry events, conferences and client visits as the LNG expert

What we're looking for

Required

• Deep LNG market expertise: strong working knowledge of global LNG pricing (JKM, TTF, Henry Hub and the relationships between them), netbacks and delivered economics, shipping and regasification costs, cargo arbitrage between basins and contract structures

• A track record of building, not just specifying: tools, models, pipelines or products you built hands-on and that other people rely on

• Strong Python and SQL, and comfort with the rest of a modern stack: APIs, databases, cloud services and version control

• Heavy, daily use of AI coding tools to prototype and ship far faster than a traditional build cycle, and the judgement to spot where an LLM gets the market wrong

• Ownership and drive: you scope the problem, pull in the right people, get it built and shipped, and fix it when it breaks, without waiting for a detailed spec

• Credible in front of trading desks: able to run a discovery call and a technical demo, and to hear what a client will pay for and what they won't

• Experience leading or working closely with engineers, and the technical credibility to set direction with them

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

• Ability to turn market complexity into rules, tests and code that make an AI agent answer like a good desk analyst

Desirable

• Experience building AI agents or LLM applications: tool calling, prompt design, retrieval and evaluation

• Experience shipping work to production alongside an engineering team (code review, testing, CI/CD)

• Familiarity with LNG data sources: price assessments, vessel tracking and shipping data, terminal and regasification data

• Experience with pricing, data or analytics platforms in the energy space, or with building one from scratch

• An existing network within the LNG trading community

What success looks like

In your first six months, you will have:

• Led the build and launch of the first version of Sparta's LNG offering: netbacks, arbitrage routes and delivered price curves in clients' hands

• Built, with the AI team, an LNG expert in Leonidas that answers the way a good desk analyst would, with an evaluation set that proves it

• Launched at least one automated product, such as a daily brief or a set of alerts, that runs every day

• Written the LNG rules every Sparta product and agent follows

• Set up, with data and engineering, pipelines that run and check themselves, so the vertical scales without manual work

• Put the product in front of LNG desks, helped sales land the first LNG clients, and fed what the market told you back into the roadmap

Is this you?

This role is for you if you'd rather build the tool than write the note about it, you like being hands-on, you make the people around you build faster too, and you measure what you've built by whether a desk will pay for it. It probably isn't for you if the part of the job you enjoy most is publishing your market view, or you'd rather hand over a spec than help build what's in it.

The Sparta Code

Understanding is non-negotiable

Understanding leads to believing. Believing leads to winning.

The 'why' is the difference between compliance and conviction. Before we execute, we ask: why does this matter, who does it serve, what changes if we win? People who understand the mission don't need to be managed.

Ask for forgiveness, not for permission

Most decisions are reversible. Most fears are not.

90% of decisions are reversible. Make them, ship, iterate. Perfection is the enemy of efficiency. Bias for action means moving before you have all the answers, but it isn't recklessness. The rule: tell the rest of us what you did, what changed, what you learned.

Fall in love with the problem

The mission wins. Your idea doesn't have to.

Solutions flatter our ego. They feel like progress. But solutions without problems are opinions, and opinions don't move customers, markets, or teammates. The goal is to find what's true, not to win the room. If your idea gets killed because a better one comes along, that's the system working.

It's your fault. Lucky you.

If it's on you, it's in your control.

True ownership sounds harsh until you feel how liberating it is. If every problem is yours, you stop spending energy on who to blame and start spending it on how to fix it. Effective leaders default to 'it's on me'. Not out of guilt, but out of agency.

Conflict is a gift

Honesty is an expression of care.

Withholding feedback is choosing comfort over growth, yours and your colleague's. Staying silent deprives others of the chance to learn. We challenge openly and with positive intent. Done with care, this builds trust. Done with ego, it destroys it.
