Senior .Net Engineer

O projekcie: Meniga builds financial intelligence for the world's leading banks - 100M+ users, 30+ countries. We're not the brand on the app. We're the layer underneath it - the one that makes the data meaningful, the experience personal, and the bank worth opening. THE WORK We're scaling engineering to match a growing business and a full commitment to AI. The platform is in active transformation - performance, architecture, and AI - and the engineers driving it care deeply about getting it right. You'll join one of three squads - each with real ownership, real clients, and real consequences. WHAT YOU GET - Competitive salary + equity: B2B, 20-29k PLN + VAT, + ESOPs - Hybrid- 2 days in office, 3 remote - Private healthcare, fitness, meal & phone allowance - A team where technical opinions are welcomed, not managed - Software that runs inside real global banks, used by millions of people every day Wymagania: WHAT WE'RE LOOKING FOR - Accountability over activity - you own a feature from the first conversation to the client's environment, and you care what happens after it ships - Business-minded - you understand what's at stake for the client, engage with Product and Commercial as partners, and treat Support tickets as signal, not noise - Can-do under constraints - on-premises bank environments are demanding; you find a way, not an excuse - Strong, production-hardened C#/.NET, with real experience in database-heavy systems - this is not CRUD territory - AI-native - you use AI tools as a natural part of how you work (Cursor & Claude Code) Codzienne zadania: - Premium Features - Extend, maintain, and re-architect high-value functionality, built for our biggest bank clients. You keep it running, you make it better. - SaaS Product Reinvention - Take an established product and bring it to the standard it deserves - technically sound, modern, and built for what comes next. - AI & On-Prem Applications - Own a portfolio of three applications - one AI-powered, all running on-premises inside bank environments. You maintain them, evolve them, and prepare them for a hybrid on-prem/SaaS future. - Own services end-to-end - not just features, but their reliability, evolution, and the client relationship around them  - Co-own the squad backlog - you’re not an order-taker; squads are small and autonomous, and you help shape direction aligned with the company’s vision  - Hold a high engineering bar - code reviews, testing discipline, pushing back when shortcuts threaten reliability - not as bureaucracy, but because you care what ships
