We are hiring an Accounting Automation Engineer to replace manual accounting work across a multi-entity, multi-country enterprise, using Claude Code and agentic AI.

You will use Claude Code and agentic AI, plus Python or JavaScript/TypeScript, to automate accounts payable, accounts receivable, reconciliations, month-end close and the wider day-to-day accounting operation. You need strong IFRS or US GAAP knowledge to get the numbers right, because an automation that posts wrong entries is worse than no automation.

We build agentic AI systems and AI agents, not fixed step-by-step workflows. Experience with rule-based workflow builders such as n8n or Zapier is not relevant to this role.

Titles we will consider: Accounting Automation Engineer, Finance Engineer, Financial Systems Engineer, Technical Accountant (with engineering background), Accounting Systems Manager (with engineering background).

Key Responsibilities

The goal is to automate the repeatable core of enterprise accounting, with human review kept only where judgment is needed.

Accounts payable

• Invoice capture and data extraction from PDFs and email, using AI where useful

• Vendor matching, coding suggestions, and 2-way/3-way PO matching

• Duplicate invoice detection and approval routing

• Payment run preparation and vendor statement reconciliation

Accounts receivable

• Invoice generation and delivery

• Cash application and bank receipt matching

• Aging reports, dunning and collections reminders

• Credit note handling and bad debt/ECL provision support

Reconciliations

• Bank and card reconciliations across all accounts and currencies

• Balance sheet account reconciliations (prepayments, accruals, deferred revenue, fixed assets)

• Intercompany and subledger-to-GL reconciliations

• Exception reports that flag only the items a human needs to review

Month-end close

• Close checklist tracking and scheduled reminders

• Recurring, accrual, prepayment and amortization journals

• Depreciation runs and FX revaluation

• Trial balance checks, flux/variance analysis, and draft commentary

• Management reporting packs

General accounting operations

• Expense report and employee reimbursement checks

• Chart of accounts and master data hygiene

• Audit support: evidence collection, PBC lists, sample extraction

• Data pipelines between ERP, banks, payment platforms and spreadsheets

Qualifications

Two things matter most, and we weigh them above everything else:

1. Strong knowledge of IFRS or US GAAP

2. Real experience with AI coding tools, ideally Claude Code, backed by solid engineering basics

We accept two paths: an accountant who learned to code, or an engineer who learned accounting. Both are judged on the same practical test.

• Hands-on experience building automations with Python or JavaScript/TypeScript (either is fine)

• Daily, hands-on use of AI coding tools, ideally Claude Code, with solid engineering basics, shipping working scripts and agents

• Ability to run local scripts and schedule jobs (cron, task schedulers or CI pipelines)

• Strong knowledge of IFRS or US GAAP, shown by ACCA, ACA, CPA or equivalent, or by several years of hands-on accounting experience

• Experience with core processes: AP, AR, bank reconciliation, month-end close

• Comfort working with APIs and MCP servers, CSV/Excel data and basic SQL

• Care for accuracy, controls and audit trails

Nice to have

• Experience in multi-entity or multi-currency environments, including intercompany and consolidation

• Experience reconciling payment processor statements across multiple jurisdictions and currencies

• Experience with shared cost services that invoice group companies, including complex expense splits and automated invoice generation

• Experience with an ERP and its API (which ERP does not matter)

• Experience building AI agents and agentic workflows, including tool use and MCP servers

• Knowledge of VAT/GST and e-invoicing rules in several jurisdictions

• Experience with Git, testing and basic cloud deployment

• Prior experience in a finance transformation or accounting operations team

• Additional languages, where our entities operate in non-English markets
