SmartCore
is a fintech holding, building a mission-critical fintech platform. Our real-time system protects millions of transactions from fraud. We are looking for a
n engineer with a strong architectural background
— someone who understands that a programming language is just a tool.

We expect you to adapt quickly and bring your own expertise:
Backend:
, TypeScript, NestJS, Go
Data:
PostgreSQL, ClickHouse, Redis, Tigergraph
Messaging / Streaming:
Kafka, RabbitMQ
Big Data:
Apache Flink
Your Challenges (Architecture & Engineering)
You will lead the development of the core of our anti-fraud system. The tasks are language-agnostic — they are rooted in Computer Science:
Real-time Scoring Engine
Design a risk-scoring engine with p99 latency in the tens of milliseconds (device fingerprinting, behavioral analytics).
Distributed Systems Design
Build an idempotent, event-driven architecture resilient to entire data-center failures.
High-Performance Analytics
Optimize data storage and access (millions of transactions) for analytics and ML models.
Data Consistency
Implement complex profile-merging logic (Customer 360) and manage distributed transactions (Saga, TCC).
What You Will Work On
- Define the technical vision and architecture of the platform (we primarily use , but expect you to bring best practices from Java/Go/Enterprise environments).
- Design data schemas for PostgreSQL and ClickHouse under extreme load.
- Build reliable data-processing pipelines (Kafka, Flink).
- Mentor the team: teaching engineers to think in terms of algorithmic complexity, memory, and concurrency — not just business logic.
- Act as an evangelist for AI-powered development (we actively use LLMs and Cursor).
Ideal Candidate Profile
- Engineering DNA
10+ years of commercial experience, including 3+ years as a Tech Lead / Architect.
- Language-Agnostic Mindset
Deep knowledge of any strongly typed language (Java, Go, C#, Rust, etc.) and willingness to write in
- System Design Mastery
Professional command of distributed-systems patterns. Experience with message brokers (Kafka/RabbitMQ) at the delivery-guarantee level.
- AI-Native Mindset (Critical)
You use LLMs not as a toy but as a productivity multiplier (boilerplate generation, refactoring, tests, data analysis). Experience with Cursor IDE or similar tools.
Nice to Have
- Experience with (even minimal)
- Experience with anti-fraud systems, billing, or high-frequency trading
- Experience with streaming systems (Flink, Spark Streaming)
We Offer
- Competitive compensation
(defined individually; aligned with Senior/Principal level) - Fully remote work with a flexible schedule
- Ability to bring best practices from your core stack into our platform
- No legacy and no bureaucracy
- Corporate access to cutting-edge LLMs and personal learning budget
