Qualified accountant is a plus, not a requirement * You bring structure to messy projects - clear plans, sharp prioritisation, and the judgement to know which details matter and which don't. * You excel at building trust with C-suite executives and finance leadership teams through clear communication and consistent delivery. * You are comfortable working cross-functionally - you have delivered through Product, Engineering, Sales, and customer teams without formal authority over any of them * You diagnose implementation issues quickly and deliver practical solutions that balance customer needs with technical feasibility. * You have a real implementation with your name on the go-live - vendor-side, consulting-side, or as the lead on a customer-side migration. Not "I've used an ERP" * You use AI tools daily, have specific opinions on where they help in delivery work and where they don't * Fluent English; additional European languages a plus * Bonus: multi-jurisdiction experience (IFRS, US GAAP, local GAAPs); experience losing a customer or missing a go-live and learning from it ## Description You'll own several concurrent implementations end to end - from contract signature to go-live. The plan, the customer relationship, the scope, the timeline, the outcome. You hand over to Customer Success once the customer is live. Your customers are Financial Controllers, Finance Directors and CFOs at fast-growing multinational SaaS and tech companies. Senior, technical, time-poor. They expect you to keep up on multi-entity accounting, consolidation, intercompany, multi-currency and statutory reporting - and to tell them straight when they're asking for something that won't work. No two implementations look the same. Every customer brings problems that don't have a textbook answer - a consolidation edge case, a migration shape the playbook doesn't cover, a process that needs rebuilding before it can be automated. You'll work the problem, ship the answer, and move on to the next one., * Own several concurrent implementations end to end, from kickoff to go-live * Run the customer relationship through implementation - Controllers, Finance Directors, CFOs * Translate finance requirements into platform design - chart of accounts, entity structure, consolidation logic, reporting * Lead data migration - chart of accounts mapping, opening balances, historical data, cutover * Hold scope through the project - keep delivery aligned to what was sold, surface and reset drift early * Push back on requests that won't work, and bring the customer with you * Spot projects going off-track before the customer does, and intervene * Train and enable customer finance teams to run on Light from day one of go-live * Contribute to the playbooks, templates, and patterns the team builds over time ## Related Videos - [Next Level Enterprise Architecture: Modular, Flexible, Scalable, Multichannel and AI-Ready?](https://www.wearedevelopers.com/videos/1017-next-level-enterprise-architecture-modular-flexible-scalable-multichannel-and-ai-ready) - [Swapping a Data Warehouse at Runtime: Zero-Downtime Migration Without Changing a Single Client](https://www.wearedevelopers.com/videos/100311-swapping-a-data-warehouse-at-runtime-zero-downtime-migration-without-changing-a-single-client) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Why make use of an integration platform in today's software developments and infrastructure?](https://www.wearedevelopers.com/videos/758-why-make-use-of-an-integration-platform-in-today-s-software-developments-and-infrastructure) - [Developer Tools for Microsoft Azure](https://www.wearedevelopers.com/videos/450-developer-tools-for-microsoft-azure) - [How to Destroy a Monolith?](https://www.wearedevelopers.com/videos/1407-how-to-destroy-a-monolith) ## Related Articles - [From developer to manager – what does it take to become an engineering manager?](https://www.wearedevelopers.com/magazine/42-from-developer-to-manager-what-does-it-take-to-become-an-engineering-manager) - [Should Tech Managers Be Developers First?
