Financial Accountant

About Onyx Capital Group

Onyx Capital Group is the world’s #1 liquidity provider for energy derivatives, trading over $3.2 trillion in notional value annually. Through Onyx Commodities, the Flux Terminal, and our trading division Axis, we dominate the benchmarks that matter — Dated Brent, S2F contracts, and beyond. We are not a bank. We are not a hedge fund. We are a technology-driven market-making powerhouse at the intersection of global energy markets, data, and engineering — and we are growing fast.

Finance at Onyx

Finance at Onyx is lean, precise, and trusted. We operate across multiple entities and currencies, hold ourselves to the highest standards of accuracy, and work closely with trading and technology to keep pace with one of the most active commodity trading operations in the world. There are no passengers here — every member of the finance team owns their work end-to-end and is expected to bring both rigour and initiative to everything they do.

The Opportunity

We are establishing our Sri Lanka office and looking for two Financial Accountants to join as founding members of the finance function. Initially responsible for a single, lower-volume entity, you will maintain books to trial balance level and work closely with our UK finance lead. As the team matures, scope and entity coverage are expected to grow. This is a rare opportunity to join a high-calibre trading firm at the start of its Asia operation and build something lasting.

• Degree in Accounting and Finance; professional qualification preferred (ACCA, CIMA, or equivalent)
• 5+ years post-qualified experience in financial accounting or a shared services environment
• Hands-on experience with journals, reconciliations, month-end close, and AP/AR processes
• Proven ability to take accounts independently to trial balance
• Multi-currency accounting experience — comfortable operating across multiple FX ledgers
• ERP system proficiency — SageIntacct or similar multi-currency accounting platform preferred
• Intermediate to advanced Excel skills — reconciliations, schedules, pivot tables, lookups
• High attention to detail and ability to work to strict close timetables
• Self-motivated and highly organised — able to manage your own workload to deadlines without day-to-day supervision, and raise issues proactively rather than waiting to be asked
• Service-oriented mindset — treats internal stakeholders as customers, responds promptly to queries from remote colleagues, and communicates clearly and helpfully across time zones
• Comfortable acting as the first point of contact for finance queries from distributed business users — able to field questions, provide guidance, and escalate appropriately
• Strong written and spoken English — clear and confident in both written and verbal communication, with the ability to work effectively across synchronous and asynchronous settings
• Experience working with globally distributed teams is strongly welcomed; comfortable collaborating with colleagues in different time zones and cultures
• Experience maintaining structured, auditable working papers and complying with documented finance SOPs

Nice to Have

• Experience in financial services, commodity trading, or regulated environments
• Familiarity with intercompany accounting and group consolidations
• Exposure to internal controls frameworks and audit preparation
• Experience supporting remote finance users or business units — fielding queries asynchronously and providing clear written guidance
• Experience with payment platform processing (subject to onshore approvals)

What We’re Looking For

You are a meticulous, self-sufficient accountant who takes ownership of your ledgers without needing to be chased. You bring structure and accuracy to everything you touch, communicate proactively across time zones, and treat the integrity of the books as a personal standard — not just a job requirement. You are someone the UK team trusts completely, because you have earned it.
