Whisk together oil, vinegar, orange juice, lime juice, lemon juice, soy sauce, paprika, cumin, chili powder, onion powder, garlic powder, oregano, salt, and pepper until well combined.
Stir in steak.
Cover and let marinate at room temperature for 30 minutes or in the fridge for up to 8 hours.
Pour steak and marinade into your 6 quart Instant Pot.
Cover and lock the lid (make sure the steam releasing handle is pointing to sealing).
Cook on HIGH pressure for 6 minutes.
When the time is up, allow a natural release for 15 minutes, then flip the valve to release the remaining pressure.
Serve with your favorite taco fixings and enjoy!
