Role Overview

As a Backend Engineer on our offline, real-time training simulation platform, you will be the driving force behind our core services. You’ll architect, develop, and maintain high-performance system.

Beyond pure backend coding, you will collaborate across teams to integrate your services into the larger system, propose and refine architectural designs, and drive end-to-end solutions from back end to frontend and DevOps.

Drive backend development for our offline, real‑time training simulation platform. You’ll build high‑performance services that ingest serial data, process event streams, and stream map‑based updates to clients.

• Algorithmic Thinking: Solve ~1400 Codeforces‑level problems; write clean, efficient Python/C++/Java code.
• Streaming & Messaging: Develop Kafka producers/consumers; maintain low‑latency WebSocket servers.
• Quality & Ops: Write unit/integration tests; set up logging, monitoring, CI/CD; ensure system reliability.
• Collaboration: Document APIs; participate in design/code reviews; work closely with UI and DevOps teams.
• System Administration: Familiarity with Linux/Unix environments, shell scripting, and performance tuning.

Backend Development & Architecture

• Design and implement scalable microservices in Python
• Define clear service interfaces (REST/WebSocket/gRPC) and data schemas
• Ensure offline-first operation—no external dependencies or cloud calls

Integration & Design Collaboration

• Work closely with frontend, mapping, and DevOps teams to integrate your APIs and streaming endpoints
• Participate in regular architecture/design reviews; propose improvements to data flow, fault tolerance, and performance
• Contribute to system-level design documents, API specifications, and integration test plans

Streaming & Messaging

• Build and maintain Kafka producers/consumers; design topics and partitioning for throughput and low latency
• Implement Faust stream-processing pipelines for real-time transformations and filtering
• Optimize WebSocket servers for efficient map-update broadcasts to multiple clients

Quality, Testing & Reliability

• Write thorough unit and integration tests 
• Set up CI/CD pipelines (GitHub Actions, Jenkins) for automated builds, tests, and deployments to Docker/Kubernetes

System Administration & Performance Tuning

• Manage Linux/Unix servers: write shell scripts, schedule cron jobs, and tune kernel/network settings for high-throughput I/O
• Profile and optimize CPU, memory, and network usage in your services
• Troubleshoot production incidents and perform root-cause analysis
