Descrição da oferta de emprego

Horizon Trading Solutions (HTS) is hiring a Senior Group Accountant( F/M) to bring accounting processes in-house, strengthen compliance with international accounting standards and external reporting requirements, and implement new tools (systems of record / automation). We currently work with external accountants; you will lead the operational transition and build the processes, controls and systems that give HTS reliable financial information.

This is a hands-on role with scope to shape how accounting works at HTS. You will combine day-to-day accounting ownership with ERP implementation and practical uses of AI. Full professional fluency in English is essential, as you will interact confidently with international stakeholders, global business partners, and external advisors across jurisdictions.

Missions

Accounting Operations

• Take ownership of the accounting function’s internalization: map all activities currently handled by external accountants and execute a phased handover covering records, opening balances, responsibilities, controls and deadlines.
• Deliver a significant improvement in the quality, accuracy and consistency of the accounting records, ensuring that transactions are properly supported, classified and reflected in the general ledger.
• Strengthen monthly, quarterly and annual closing schedules, documented journal entries, analytical reviews and clear explanations of material movements and variances.
• Establish rigorous balance-sheet reconciliations for all significant accounts, with documented support, timely investigation of discrepancies and disciplined clearance of aged or outstanding items.
• Develop a deep understanding of the accounts and underlying business flows, enabling reliable financial analysis, early identification of accounting issues and clear communication of financial performance to management.
• Improve accounting policies, documentation and internal controls in line with applicable accounting standards and external reporting requirements; coordinate statutory accounts, tax filings and audit requests with external advisors while retaining clear internal ownership.

ERP implementation

• Lead a significant 12-month ERP implementation project that must be delivered from requirements definition through testing, data migration, go-live and stabilization, working closely with internal teams and implementation partners.
• Define the chart of accounts, analytical dimensions, accounting rules and approval workflows; connect purchasing, billing and banking processes to the ledger.
• Document workflows, train users and support adoption; prioritise improvements that reduce manual work, strengthen controls and shorten the close.

Artificial Intelligence (AI)

• Identify, assess and pilot high-value AI applications across accounting, including invoice and document extraction, reconciliation support, anomaly detection, close assistance, cash-flow analysis and first drafts of variance commentary.
• Build controlled AI workflows using approved tools that protect confidential data; validate outputs against source records and retain clear human accountability for accounting judgments, journal entries, approvals and payments.
• Define success measures for each use case and turn successful pilots into documented, scalable workflows that colleagues can use consistently.

What you bring

• A degree in accounting, or an equivalent professional qualification, and at least five years of relevant accounting experience.
• Hands-on ownership of general ledger accounting and month-end and year-end closes, with strong reconciliation skills and a sound command of international accounting standards and cross-border reporting requirements.
• Experience working with external accountants and auditors. A background combining accounting practice and an in-house accounting role would be valuable. Experience in a SaaS environment would be an advantage.
• Practical experience implementing or significantly improving an ERP, including defining requirements, testing workflows and validating migrated data.
• Strong Excel skills and confidence working with accounting data. Experience with reporting tools, data integrations or workflow automation is a plus.
• A structured, detail-oriented approach, with the autonomy to take work through to completion and the ability to prioritise operational deadlines alongside improvement projects.
• Full professional fluency in English, with clear communication and a collaborative mindset: you can explain accounting issues to non-specialists and collaborate effectively with international stakeholders, colleagues, advisors and system partners.
