Urgent! MongoDB Expert with Scala Job Opening In Gdańsk – Now Hiring Scalac
📍 Remote | EU Time Zone | Contract / B2B
We’re looking for a Senior Scala Developer with strong MongoDB expertise to join a high-impact project with one of our clients.
This is an opportunity to tackle complex technical challenges in a system that’s critical for the client’s operations, while also shaping the long-term architecture.
Our client operates around 30 microservices built in Scala, all using MongoDB Scala Driver as their primary database.
The system currently relies heavily on transactions across multiple collections, which has led to:
~1 million MongoDB sessions open simultaneously
Terminated transactions due to overload
Severe performance issues with queues of up to 2–4 hours
The client recognizes this approach isn’t sustainable and wants to fix the short-term issues while also redesigning the long-term architecture.
You will play a key role in both the stabilization and the future redesign of the platform:
Short-term goals:
Investigate why so many sessions/transactions are created
Fix code and/or adjust MongoDB Driver usage to stabilize operations
Long-term goals:
Redesign the shared data model across 30 services to eliminate the need for transactions
Provide guidance and hands-on support in implementing a scalable, transaction-free architecture
Potentially tune and optimize MongoDB for high-performance workloads
Proven experience with Scala (production-grade systems, microservices architecture)
Deep knowledge of MongoDB (transactions, drivers, performance optimization)
Strong problem-solving and debugging skills in distributed systems
Experience with data model redesign and building scalable, high-performance architectures
Ability to work independently and provide technical leadership
Nice to have:
Experience with MongoDB cluster tuning and performance optimization
Background in large-scale system migrations or refactorings
Work on a technically challenging project that directly impacts system performance
Chance to influence and redesign a critical data model used across 30+ services
Remote-first engagement with flexibility
Rate up to 40 EUR/h
🚀 If you’re an experienced Scala + MongoDB expert who enjoys solving deep technical challenges and building scalable solutions, we’d love to hear from you.
