Original job description

Overview

Cloud operations are entering a new era. COSMIC is building agentic infrastructure that helps engineers define goals, policies, and operational intent while autonomous systems safely execute routine work across Microsoft’s largest Kubernetes fleets.

Part of M365 Substrate Core, COSMIC is modernizing Microsoft’s compute platform with turn-key geo-presence, security, high availability, fault isolation, and automated cloud buildout, improving service agility, reliability, compliance, and cost efficiency.

Job Purpose

We are seeking a Senior Software Engineer to build autonomous operational capabilities for COSMIC.

You will own significant features and services that enable AI agents to coordinate and safely execute operational workflows at fleet scale, including deployment, capacity, resiliency, recovery, optimization, evaluation, and continuous learning.

Working with product managers, architects, and engineers across COSMIC, you will take problems from design through production, make sound technical decisions, use production signals to improve the system, and help other engineers succeed through technical leadership.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Responsibilities

Own the design, implementation, rollout, and operation of significant COSMIC App Platform features and services from requirements through production.
Build distributed platform and orchestration components that enable AI agents to coordinate and execute deployment, capacity, resiliency, recovery, and optimization workflows at fleet scale.
Design safety boundaries including sandbox isolation, scoped identity and access, policy and approval checks, auditable execution, rollback, blast-radius containment, and human oversight.
Drive production readiness through health-gated releases, observability, alerts, runbooks, on-call support, and incident follow-up.
Build evaluation, experimentation, feedback, and learning loops with measurable system-quality and operational outcomes.
Translate customer and operational needs into sound designs, testable software, and clear success criteria while resolving cross-team dependencies and delivering end-to-end scenarios.
Investigate complex production issues using telemetry and data, identify root causes, and deliver durable fixes that improve reliability and supportability.
Lead feature-level technical reviews, contribute to architecture and roadmap decisions, mentor engineers through design and code reviews, and improve reusable engineering patterns and tooling.

Qualifications

Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python or Rust.

Other Requirements:

Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include but are not limited to the following specialized security screenings:

Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.

Preferred Qualifications:

Master's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python
OR Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python
OR equivalent experience.
Experience designing, building, and operating distributed systems, cloud services, or Kubernetes-based infrastructure.
Experience owning complex features or services from design through production, including reliability, instrumentation, and supportability.
Experience with production AI or agent systems, workflow orchestration, control planes, or intelligent automation.
Experience implementing safety, policy, identity, authorization, observability, evaluation, or approval mechanisms for automated systems.
Solid coding, debugging, testing, and systems design skills, with attention to maintainability and operational quality.
Experience using telemetry, experiments, and customer feedback to improve product and system outcomes.
Ability to communicate technical decisions clearly and collaborate effectively across engineering and product disciplines.
