Identifies best practices and coding patterns and provides deep expertise in the coding and validation strategy. Creates and applies metrics to drive the quality and stability of code, as well as appropriate coding patterns and best practices.
Leads efforts to apply knowledge of debugging tools, logs, telemetry, and other methods, and leads verification of assumptions through writing and developing code proactively before issues occur and reactively as issues occur across products. Leverages minimal telemetry data, triangulates issues, and resolves with minimal iterations. Leads retrospective debugging of solutions to identify root causes of problems.
Reviews the code of a product to assure it meets the team's and Microsoft’s quality standards, is reliable and accurate, and is appropriate for the scale of the product/solution area. Applies feedback to current and future iterations. Participates in code reviews to ensure coding standards are followed. Considers diagnosability, reliability, and maintainability when reviewing code, and understands when code is ready to be shared or delivered. Applies and screens for coding patterns and best practices in reviews and provides feedback on code to drive adherence to best practices.
Implement
Leverages subject-matter expertise of cross-product features with appropriate stakeholders (e.g., project managers) to drive multiple group's project plans, release plans, and work items. Breaks down long-term project vision into milestones as part of an overall roadmap. Guides other members for project estimation and escalates any issue that would cause a major delay.
Leads efforts for creation and conducting of experimentation to determine the effectiveness of changes, monitors developments for prototyping and testing products, interprets results, and decides on next steps or ship decision from results. Drives identification of the correct metrics for experimentation in determining improving customer value.
Leads the creation of implementation framework as necessary, following industry standards. Leads implementation and deployment of the solution in the existing framework. Holds accountability for the impact of build deployments on both users and other services. Optimizes deployments within products and components to meet differing business objectives. Leads efforts to assure that solutions are deployed safely.
Reliability and Supportability
Maintains operations of live service as issues arise on a rotational, on-call basis. Implements and helps others implement solutions and mitigations to complex issues impacting the performance or functionality of Live Site services. Reviews and writes issues postmortem and shares insights with the team.
Holds accountability as a Designated Responsible Individual (DRI) and mentors' other engineers across products/solutions, working on call to monitor system/product/service for degradation, downtime, or interruptions. Alerts stakeholders as to status and initiates actions to restore system/product/service for complex issues. Develops a playbook for the team to resolve issues. Coordinates people and resources to ensure DRI responsibilities are covered across teams. Responds within Service Level Agreement (SLA) timeframe. Has line of sight to incidences and plans to address emerging issues. Leads efforts to reduce incident volume, looking globally at incidences and providing broad resolutions. Escalates issues to appropriate owners.
Integrates, designs, and reviews others' work across a team or product to integrate instrumentation for gathering telemetry data on system behavior such as performance, reliability, availability, usage, and safety mechanisms. Drives sustaining feedback loops from telemetry resulting in subsequent designs. Ensures solutions are scalable, financially responsible, and meet capture/storage guidelines. Leads the creation of outputs of telemetry such as notifications or dashboards.
Leads efforts to collect, classify, and analyze complex data and analyses on a range of metrics (e.g., health of the system, where bugs might be occurring). Leads the refinement of products through data analytics and makes informed decisions in engineering products through data integration.
Engineering Excellence
Leads efforts to enhance, reuse, contribute to, and identify new software developer tools to support other programs and applications to create, debug, and maintain code across products.
