About Joulen
Joulen is the software layer for GB energy flexibility, built in Belfast, built to matter globally. Our platform forecasts energy needs and market value, decides the optimal path, and controls assets to deliver it, maximising returns for residential, commercial and grid-scale customers. Joulen runs on six operating principles: Customer Centricity, Talent Density, Move with Urgency, Radical Candour, Disagree & Commit, and Owner-Operators, set out in our internal Culture Deck. This is a company that designs its culture as deliberately as it designs its product, and this role exists to make sure the people function lives up to that standard.
The Role
You will own the accounts receivable cycle end to end. That means reconciling our billing and settlement positions with third parties including EPEX SPOT and Elexon, calculating revenue share due to partners, resolving imbalance and settlement differences, and making sure partners are paid the right amount on time. You will be building and improving how AR runs at Joulen while it is still taking shape, and you will have direct visibility with our partners and our leadership team.
Alongside AR, you will support the wider finance function across accounts payable, payroll, month-end, and the preparation of accounts.
- Accounts receivable and settlement
- Reconcile billing and settlement data between Joulen, EPEX SPOT, Elexon, and partner systems, and investigate variances to resolution.
- Own aged debt, cash collection, and AR reporting, and escalate exposure early.
- Document and improve AR controls and process as trading volumes and partner numbers grow, including working with our engineering and product teams on automation.
- Supporting the Wider Finance Function
- Support accounts payable, supplier payments, and expenses.
- Support the monthly payroll cycle.
- Contribute to month-end close, balance sheet reconciliations, and the preparation of management and statutory accounts.
- Support audit and diligence requests as we mature our finance function toward public company standards.
Essential Criteria
- 3 to 6 years of hands-on accounting experience, with a substantial portion in accounts receivable, billing, or settlement.
- Proven ability to run a reconciliation independently: you can take an unexplained difference, work out where it came from, and close it out without being walked through it.
- Strong Excel skills, and comfort working with large volumes of transactional data from multiple systems.
- Working knowledge of the wider accounting cycle, including AP, payroll, and month-end.
- You will be explaining variances to partners and to people outside finance.
- Familiarity with GB market settlement, BSC processes, or wholesale trading reconciliation.
- SQL, Power BI, or experience automating finance processes.
What we offer
- Competitive salary
- 20 days annual leave plus 11 public holidays
- Option to buy additional annual leave
- Pension
- Life Assurance
- Private Medical Insurance
- Paid sick leave
