Welcome to life. A place where there is always someone who works harder or smarter than you. If your workaholic colleague is bringing more value to the company, she should be promoted faster and receive larger compensation than you. The key word here is value. Take a big step back and consider what value your colleague brings to the company. What "jobs" and "roles" does she fulfill within the team? Is she staying up late fixing random bugs or doing things others don't want to do? Is she staying late making sure a release goes well or delivering insights to execs to push the product forward? You used the phrase "stuck with" which suggests negativity and possibly a sense of "it's unfair to me". Is she actively working against the team or is she outperforming others? Consider what value you bring to the team. Do your manager/people in charge of your compensation recognize the value you bring? As with most "soft skill" conversations the details of a situation are key.
