• Collaborate with Product, QE, and Data colleagues to ship high-quality releases on a continuous delivery cadence.
• Own your work throughout the entire product development lifecycle, from technical design and planning to market release.
• Review the code of peers in a team.
• Support and mentor team members, helping grow backend engineering as a discipline.
• Identify improvements, highlight risks vs benefits, and translate them into technical requirements.
• Work with the product team, providing technical knowledge and expertise, helping to design the future of our products.
• Participate in paid on-call rotation.
