In short

Microsoft seeks a Senior Software Engineer for the Agent 365 Foundation team. This hands-on role involves designing, building, and operating the gateway and ingress path for Dynamics 365 and Power Platform traffic, focusing on reliability, security, and performance at scale. The engineer will work extensively with C# and Go, handle complex networking protocols, and participate in an on-call rotation.

Responsibilities

Design, implement, and operate L4 and L7 ingress components including gateways, proxies, load balancing, and routing policy for Dynamics 365 and Power Platform traffic.
Own the protocol layer, managing TLS termination, certificate lifecycle, HTTP/2 connection management, gRPC routing, and performance characteristics.
Build resiliency into the request path using health-based routing, retries, circuit breaking, load shedding, rate limiting, and regional failover, validated through fault injection and load testing.
Strengthen the security posture of the edge by implementing DDoS detection and mitigation, WAF and abuse-mitigation policies, tenant isolation, and defenses against application-layer attacks.
Integrate and tune Azure Front Door and related edge services with first-party gateway components, making strategic decisions about layer responsibilities.
Instrument the ingress path for real-time monitoring of latency, errors, and saturation, and lead incident response, root-cause analysis, and follow-through to prevent recurrence.
Collaborate with service teams on onboarding, capacity, and traffic-shaping decisions, and elevate the engineering bar through design and code reviews.

Requirements

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 equivalent experience.
Ability to meet Microsoft, customer, and/or government security screening requirements, including Microsoft Cloud Background Check.

Desired 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.
Proven knowledge of L4 and L7 networking: TCP connection behavior, load balancing, proxying, routing, DNS, and the tradeoffs between transport-level and application-level handling.
Practical depth in TLS, HTTP/2, and gRPC, including certificate management, handshake and connection tuning, multiplexing behavior, and diagnosing protocol-level failures from packet captures and traces.
Production experience with C# or Go, and the willingness to work fluently in both.
Demonstrated experience making services resilient under stress — designing for graceful degradation, and validating it rather than assuming it.
Experience operating what you build, including on-call ownership, live-site debugging, and post-incident improvement.
Hands-on experience with Azure Front Door, Azure networking, or comparable CDN and global edge platforms.
Direct experience with DDoS protection: volumetric and application-layer attack detection, mitigation policy, rate limiting, and bot management.
Experience running ingress in Kubernetes environments, including service mesh and Envoy-based data planes.
Familiarity with multi-tenant SaaS traffic patterns, such as those in Dynamics 365 or Power Platform, and the isolation and fairness problems they create.
Background in performance analysis and capacity planning for high-throughput, low-latency systems.

Benefits

The typical base pay range for this role across the U.S. is USD $119,800 - $234,700 per year.
