Backend roles are language-agnostic and broad in scope. A single work session might include a Python FastAPI endpoint, a Node.js Express middleware chain, and a PostgreSQL query plan to review. You'll evaluate API design decisions (REST vs. GraphQL, pagination strategies, versioning approaches), database schema choices (normalization, index selection, query optimization), caching strategies (Redis, in-memory, CDN), and message queue implementations (Kafka, RabbitMQ, SQS). Tasks are independent and self-contained, so you can work in your strongest language each session. Infrastructure tasks (Dockerfile quality, Kubernetes manifests, Terraform configurations) appear in this category too.
Common: Node.js, Python (Django/FastAPI), Java, or Go. You don't need to know allβplatforms let you filter by language. However, knowing multiple increases opportunity volume.
You'll assess schema normalization, indexing strategy, query optimization, and scalability. Tasks include spotting N+1 problems, evaluating ACID compliance, and reviewing NoSQL vs relational trade-offs.
Typically 2+ years professional backend development. You need to understand API design, databases, caching, message queues, and distributed systems concepts. Bootcamp grads with 2+ years experience may qualify.
Helpful but not always required. Some roles evaluate Docker/Kubernetes, but most focus on code logic. DevOps skills unlock additional tasks and may increase rates by 10-20%.
