Sid Dahiya
Principal Software Engineering Manager at Microsoft
I lead the platform teams thousands of engineers depend on. With over a decade at Microsoft, I take the systems that quietly tax everyone downstream — telemetry, release pipelines, feature-flighting — and turn them into multipliers, while growing the engineers who own them. Today I lead Release Infrastructure for Microsoft Teams, shipping to nearly a billion people a day.

Leadership Highlights
The through-line of my career: build the team, fix the platform, and leave both stronger than I found them.
Builds Teams from Zero
Stood up the Unified Telemetry team from scratch and rebuilt Office's Customer Experiences group from a scattered feature crew into a high-performing engineering team — hiring, coaching, and retaining engineers through multiple reorgs.
Influence Beyond the Org Chart
Grew a customer-health metric from a dashboard into the org's de-facto quantitative signal — now part of the senior-leadership Monthly Product Review — and architected the end-to-end data flow behind Office's pivot to Microsoft Copilot.
Velocity Without Breakage
Co-founded "Turbo," a fast-release pipeline shipping AI features in days instead of weeks — 8 squads onboarded, 2x release cadence — and designed test-pipeline auto-retry that halved stuck rollouts and lifted PR throughput 60%.
AI-Forward Engineering Leadership
Setting direction for agentic release intelligence: AI that promotes, pauses, and rolls back releases under human oversight — replacing calendar-based gates with data-driven promotion, with engineers steering.
Experience
11+ years at Microsoft — from new-grad engineer to principal-level leadership across three platform organizations
Principal Software Engineering Manager
Microsoft
Lead the engineering team that owns Microsoft Teams' feature-flighting and release-safety platform — shipping Teams to ~1 billion users a day. Driving data-driven, automated ring promotion (crash-free rate, test pass rate, performance, incidents, security coverage) in place of calendar-based gates, and setting direction for agentic release intelligence: AI promoting, pausing, and rolling back releases under human oversight, with engineers steering.
Principal Software Architect
Microsoft
Architect of record for Microsoft Teams' feature-flighting platform, scaling release infrastructure for 1 billion daily users. Co-founded "Turbo," a fast-release pipeline that ships AI features in days instead of weeks — onboarding 8 squads for 2x release cadence — and designed test-pipeline auto-retry that restored availability to 100%, halved stuck rollouts, and lifted PR throughput 60%.
Principal Software Engineering Manager
Microsoft
Built Office's Customer Experiences (CX) engineering team from a scattered feature crew into a high-performing group, and grew the CX customer-health metric from a dashboard into the org's de-facto quantitative signal — now part of the senior-leadership Monthly Product Review. Architected the end-to-end data flow for the org's pivot to Microsoft Copilot across Word, PowerPoint, Excel, Loop, OneDrive/SharePoint, Teams, and Outlook.
Principal Software Engineering Manager
Microsoft
Led the Unified Telemetry team — the SDKs, compiler, and services that standardize how products across Microsoft's Experiences & Devices org collect telemetry. Established the .NET SDK (with an OpenTelemetry sink) as the de-facto replacement for the deprecated legacy SDK, adopted beyond Office, and steadied and grew the team through multiple reorgs while hiring and coaching engineers.
Senior Software Engineering Manager
Microsoft
Moved from a Principal individual-contributor role into management to stand up and lead the newly formed Unified Telemetry team, unifying a fragmented set of platform-specific telemetry libraries into one modern, cross-platform SDK suite with the packaging and pipelines partners needed to adopt it.
Senior Software Engineer
Microsoft
Owned client telemetry, privacy, and cost-efficiency platforms used across Microsoft. Lead developer for Office's privacy-concern detection tooling — first adopted outside Office by Teams, OneDrive, and Visual Studio. Drove a legacy-data-reduction effort cutting Office's telemetry collection ~25% (saving hundreds of thousands of dollars a month), and ~2,248 CPU cores in Europe during COVID capacity pressure. Built and shipped the cross-platform telemetry SDKs — C++ core with Java and Objective-C wrappers, plus JS/TypeScript and .NET — frequently as the sole engineer.
Software Engineer II
Microsoft
Productionized Office's observability tooling into the Diagnostic Data Viewer — Microsoft's user-facing data-transparency experience — shipping across Win32, Mac, and iOS from investigation to shipped in five months. Rolled a privacy-compliant telemetry wrapper across ~288 Office projects, drove ITAR/GCC compliance, and improved telemetry-config core performance ~5x. Promoted to Senior Software Engineer.
Software Engineer
Microsoft
Built "Office Telemetry Studio," the developer tool Office engineers relied on for the better part of a decade — the foundation later productionized into the Diagnostic Data Viewer. Fixed a customer-blocking startup crash (~3,000 → ~50 crash reports a day) and built "Dynamic Config," a runtime telemetry-sampling system on the company's experimentation platform.

Real Time Telemetry Monitoring Tool
2021EP3808099A1
Technologies that help developers determine server resource usage caused by client application generated events, balancing the benefit of a given event with an estimated cost to process it.
View on Google Patents →Sampling of Telemetry Events to Control Event Volume Cost and Address Privacy Vulnerability
2024EP4356250A1
A system and method for sampling telemetry events — generating models that define conditions for event reporting and instructing client devices on whether to report incoming events.
View on Google Patents →Optimizing Telemetry Volume
2025US20250138821A1
A system for optimizing telemetry volume by calculating optimized sampling rates to reduce overall volume while maintaining tracking fidelity for application products.
View on Google Patents →Privacy & Data Transparency
Deeply invested in building systems that respect user privacy while delivering valuable product insights.
