No. Performing under adversarial pressure from co-workers is not inherently part of the job of being a developer. Even for positions that would involve frequent on-calls or racing to fix failing production systems, developers can be a collaborative team uniting around an external issue, not adversaries against their fellow co-workers. If your company has a work environment of adversarial competition or hostility, you will have trouble retaining and attracting employees and should rethink your culture.
