      \n While the upstream phase of bringing our clients\u2019 visions to life can be challenging, it offers the rewarding experience of setting the direction for the system and driving the entire development process forward. One of SUN\u2019s greatest appeals is that, while you\u2019ll have significant autonomy to take on projects, we also provide a supportive environment where you can consult with your managers and colleagues when you encounter difficulties\u2014allowing you to take on new challenges with confidence. If you\u2019re looking to take on more upstream projects or gain a broader range of experience, we invite you to grow with us.\n <\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
