Principal Software Engineer

The Windows Enterprise and Security (ENS) team builds foundational capabilities that keep the Windows client and server operating systems secure and trusted at global scale.

As a Principal Software Engineer in ENS India, you will design and ship security and enterprise features that land broadly across the Windows ecosystem. You'll work closely with partner teams, including engineering counterparts in Redmond, to build secure-by-design, reliable-by-default solutions that meet the bar for global deployment.

Responsibilities

Security & OS Feature Engineering

• Design and implement Windows security and enterprise capabilities that ship at scale across client and/or server.
• Build features across foundational areas such as hardware-backed security, cryptography, identity/authentication, and enterprise management experiences.

Engineering Excellence (Quality, Reliability, Operability)

• Produce robust, testable, maintainable code with strong engineering rigor, including diagnostics and operational readiness suitable for global rollout.
• Partner with security and platform stakeholders to ensure designs align to secure-by-default principles and meet compliance/assurance expectations.

Cross-team Collaboration & Delivery

• Collaborate with ENS partner teams in Redmond and across Windows engineering to deliver shared roadmaps and aligned technical outcomes.
• Drive end-to-end execution: requirements → design → implementation → validation → deployment, with an ownership mindset.

AI Forward Engineering

• Leverage AI-assisted and agentic engineering workflows to accelerate design, debugging, testing, and documentation,while maintaining strict verification and security quality bars.
• Establish reusable patterns (e.g., prompt/playbook snippets, validation checklists, automation hooks) that make AI usage repeatable and safe for the team.

Qualifications

Required/Minimum Qualifications:

• Bachelor’s Degree in Computer Science or related technical field AND 12+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python.
• OR equivalent experience.
• Solid experience building and shipping production software in one or more systems languages (e.g., C/C++/C#/Rust) and debugging complex systems.
• Experience in one or more: platform security, cryptography, identity/authentication, secure boot/TPM, device security, enterprise policy/management, licensing/entitlement systems.
• Experience designing and developing features in large-scale, performance-sensitive systems, ideally with Windows / OS / systems depth.

Preferred Qualifications:

• Public Key Cryptography/Post Quantum Cryptography (PQC).
• Track record of driving engineering quality: testing strategy, telemetry, reliability, and operational excellence.
• Comfort partnering across geographies and influencing designs with stakeholders across engineering, security, and program leadership.
