Tips for your Software Engineer resume

Mid-level SWE resumes should show ownership, not just contribution. Use bullets that start with 'Led', 'Designed', 'Owned' alongside 'Built' and 'Shipped'. Hiring managers look for evidence you can operate independently and think beyond your immediate ticket.
