Software Developer Onboarding Guide

What a good one includes

• A chronological checklist of administrative tasks, access requests, and initial repository setups to guide the developer through their first five days.
• Foolproof, copy-pasteable terminal commands and configuration steps for setting up the local database, dependencies, and development servers.
• A high-level diagram and explanation of the system architecture, service boundaries, third-party integrations, and data flows.
• A step-by-step walkthrough of your branch naming conventions, pull request expectations, code review processes, and CI/CD pipelines.
• A low-stakes, real-world ticket—such as fixing a typo or adding a simple test—designed to get the developer through the entire deployment pipeline within their first week.
• A list of designated points of contact for specific repositories, infrastructure components, and cultural questions so the new hire knows exactly who can unblock them.

Common mistakes to avoid

• Assuming local setup instructions are up-to-date instead of testing them regularly on clean machines to prevent day-one technical blocks.
• Dumping massive system documentation and codebases on a new hire on their first day, which leads to cognitive overload rather than actionable progress.
• Forgetting to provision GitHub, AWS, Jira, and Slack access prior to their start date, leaving new hires sitting idle and feeling disconnected.
• Failing to document team communication norms, such as core collaboration hours, Slack etiquette, and documentation standards, which creates unnecessary social anxiety.
