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. Meniga’s offices are in London, Reykjavik, Warsaw and Cairo.
Senior .NET Engineer
Financial intelligence for 100M+ users across the world's leading banks.
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:
You will join one of our core engineering squads, each owning critical parts of our platform:
- 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.
WHAT YOU’LL DO
- 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
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)
TECH
Must have: C# / .NET · MSSQL or PostgreSQL
Nice to have: Kafka · Azure · RabbitMQ · GCP · Kubernetes · Terraform · Python · Helm Charts · Fintech
Most systems are on premises at client sites and actively migrating toward cloud. You'll work with real constraints, not just clean-slate architecture.
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
HOW WE HIRE
- Screening- 30 min call. Real projects, real decisions, real trade-offs.
- Meet the CTO- 15 min. We want to understand how you think and what you care about. So does he.
- 90 min interview- onsite or call. One real problem (coding + design + AI), system design, and a conversation with a senior team member. AI tools are welcome.
Skills Required
- Strong experience with C# / .NET and backend development
- Solid experience working with MSSQL or PostgreSQL
- Experience working with cloud environments (preferably Azure)
- Bachelor's degree in Software Engineering, Information Technology, or a related field
