Billing Manager Permanent employee · Full-time · Berlin (HQ) Our Mission For You Own the invoicing engine of a hyper-growth energy-tech company. Your work directly protects our cash flow and keeps our growth engine running. Invoicing directly affects our cash flow in the millions. This role is a lever, not a cost center. trawa enables mid-sized companies to access green, intelligent energy. We're a hyper-growth company with strong team growth, rising invoice volumes, and increasing complexity per invoice. Individual contracts, PPAs, spot, futures, EEG direct marketing, grid fees, taxes: every customer segment is a small puzzle. Today, that puzzle is solved mostly manually, and it needs to move to the next level. You'll build order out of that complexity. You'll jump into individual invoices when it matters. At the same time, you'll design the process that makes those individual jumps unnecessary. You'll be part of our Billing Tool Rollout and help prepare invoicing for our ERP migration. This is a hands-on role for someone who wants to own the operation, not just manage it. Tech/Data team, where consumption data, time series, and energy accruals are your input Establish escalation paths and priority logic with Sales and CS, so edge cases don't block the standard process Data Quality & Handover to Accounting Ensure invoicing data flows cleanly into accounting, as the interface to our accounting team Contribute to month-end close: clean invoicing cut-off, documented open items, accruals-relevant data ready on time Audit-readiness from an invoicing perspective: process documentation, invoice-level traceability, controls Who You Are Must-haves 3+ years in Billing, Order-to-Cash, Finance Operations, or similar operational Finance roles Scale-up experience, with at least one station at a fast-growing company.
