Middle/Senior Backend Engineer

The MissionAt Droppii, we are building a massive e-commerce ecosystem. We don't just build websites; we engineer high-throughput, low-latency distributed systems.We are looking for a Senior Backend Engineer who is language-agnostic and systems-oriented. You will not be confined to a single framework. Instead, you will choose the right tool for the job—whether it’s .NET/Java for core transactional services, Python for CRM system, or Node.js for lightweight I/O operations.If you obsess over System Design, Observability, and Scalability, and you believe that "You Build It, You Run It," this role is for you.What You Will Do (The Impact)1. Architecting Scalable SystemsDesign and implement Event-Driven Microservices that can handle high concurrency during flash sales and peak traffic.Make critical architectural decisions: decoupling monoliths, defining service boundaries (DDD), and selecting communication patterns (gRPC vs. REST, Sync vs. Async).Solve hard distributed system problems: Data Consistency (Saga Pattern, Outbox Pattern), Idempotency, and Distributed Locking.2. Polyglot EngineeringWork across a diverse stack. While you may have a "core" language (e.g., .NET or Java), you are comfortable reading, debugging, and writing code in Python or Node.js when the architecture demands it.Refactor legacy codebases into modern, clean, and testable microservices.3. DevOps & Infrastructure as CodeBridge the gap between Code and Ops. You don't just throw code over the wall; you own your service’s lifecycle.Write Helm charts, configure Kubernetes manifests, and manage CI/CD pipelines (GitHub Actions/Azure DevOps).Optimize database performance (Index tuning, Query analysis) for PostgreSQL and handle caching strategies with Redis.4. Reliability & Engineering ExcellenceChampion Observability: Implement distributed tracing (OpenTelemetry), metrics (Prometheus/Grafana), and structured logging to ensure we know exactly what is happening in production.Conduct rigorous code reviews and write RFCs (Request for Comments) for major technical changes.Mentor mid-level engineers, fostering a culture of "Clean Code" and "Testing First."
