포지션 상세
Job Summary
A backend engineer who builds the foundation every other team depends on.
Next Securities builds stable trading infrastructure and scalable services with a technology-centric mindset.
We are in the early stages of designing and implementing new platform systems, and we are at a point where we can define superior technical standards without the constraints of the existing structure. We are a team where engineers proactively design and complete the direction of the platform in an environment requiring high throughput, real-time data, multi-tenant reliability, and high availability. Service Platform Team's services sit on the critical path of every product team, therefore the quality of our design directly shapes the velocity and stability of the entire engineering organization
· Design and enhancement of architecture for large-scale event processing, real-time data streams and high-fan-out workloads
· Domain model and data design that ensure correctness, consistency, and reliable delivery across shared services
· Non-disruptive deployment, real-time monitoring, and continuous improvement of the failure response system
· Standardization of service structure through event-driven architecture and reusable common modules
· Participation in establishing a long-term technology roadmap and structural design for next-generation trading infrastructure
*In the process of building a new system together, engineers stand at the center of technical decision-making and directly participate in structural design from a long-term perspective.
[Technology Stack]
· Language / Framework: Kotlin/Java, Spring Boot
· Infra / Tools: Kafka, Redis, Kubernetes, Docker, AirFlow, ELK, Grafana
· Database: PostgreSQL, Oracle
· Ops: Establishing automated deployment, service monitoring, and log analysis environments
· Experience in designing and operating service architectures based on Java, Kotlin, and Spring Boot
· Experience in large-scale, high-throughput processing and performance optimization
· Experience in RDBMS or NoSQL design and performance improvement
· Experience building distributed architectures using Kafka, Redis, and messaging/caching systems
· Disaster response and non-disruptive deployment experience for a stable operating environment
· Business-level English proficiency (reading, writing, and verbal collaboration)
