- Find an experienced team with a history of delivering projects into production, and do whatever it takes to get on that team.
- Stay with the project through delivery to production. Even better, stay with the project through the first service release.
- Be a major contributor. Shift rolls as necessary to maintain this status (i.e. requirements lead to design lead to testing lead).
- Keep your eyes and ears open. Roll up your sleeves and learn everything you can from the 'stars' on that team.
Repeat this as often as you can throughout your career to continue your growth and keep your skills current.
