Responsibilities:

• In this role, you will write reusable, testable, and efficient code using test-driven development, collaborate with engineering, product, and business teams to ship new features, and address non-functional requirements like security, performance, and load
• You will also be expected to raise engineering standards through ownership, technical judgment, mentoring, and the responsible use of AI — we expect every engineer, manager, and leader to actively leverage AI to enhance productivity, quality, innovation, and customer value, as AI is embedded in our workflows, decision-making, and products
• Raise standards for technical troubleshooting, root cause analysis, and resolution quality
• Improve team capability through mentorship, knowledge sharing, and clear documentation
• Reduce repeat issues by driving systemic fixes and improving diagnostic approaches
• Strengthen cross-functional execution by improving clarity and collaboration with Engineering and Product
• Identify opportunities to improve processes, tools, and workflows that increase scalability and efficiency
• Leave systems, documentation, and team capability stronger than they found them
• Use AI tools to accelerate development, root cause analysis, summarize case histories, and generate high-quality knowledge base content
• Identify automation opportunities that reduce manual troubleshooting effort
• Quantify and demonstrate measurable improvements enabled by AI (e.g., reduced resolution time, improved documentation quality)
• Share AI best practices with peers and contribute to raising AI capability across the team
• You’ll apply AI every day to business challenges - improving efficiency, contributing solutions, and driving results for your team, our company, and our customers
