Senior Software Engineer Jobs

About The Position

Requirements

• Bachelor's degree in Computer Science or a related technical field and 4+ years of technical engineering experience coding in languages including C, C++, C#, Java, JavaScript, or Python, or equivalent experience.
• Ability to meet Microsoft, customer, and/or government security screening requirements, including passing the Microsoft Cloud Background Check upon hire or transfer and every two years thereafter.
• Proven knowledge of L4 and L7 networking, including TCP connection behavior, load balancing, proxying, routing, DNS, and transport-level versus application-level tradeoffs.
• Practical depth in TLS, HTTP/2, and gRPC, including certificate management, handshake and connection tuning, multiplexing behavior, and diagnosing protocol failures using packet captures and traces.
• Production experience with C# or Go and willingness to work fluently in both.
• Experience designing services for resilience and graceful degradation under stress, and validating those behaviors.
• Experience operating built systems, 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, including 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 and the isolation and fairness challenges they create.
• Background in performance analysis and capacity planning for high-throughput, low-latency systems.

Nice To Haves

• Master's degree in Computer Science or a related technical field and 6+ years of technical engineering experience coding in languages including C, C++, C#, Java, JavaScript, or Python; or bachelor's degree in the field and 8+ years of such experience; or equivalent experience.
• Hands-on experience with Azure Front Door, Azure networking, or comparable CDN and global edge platforms.
• Direct experience with DDoS protection, including 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 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.

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, including TLS termination and certificate lifecycle, HTTP/2 connection management, gRPC routing and streaming behavior, and performance tuning.
• Build and validate request-path resiliency through health-based routing, retries and hedging, circuit breaking, load shedding, rate limiting, and regional failover; use fault injection and load testing to prove behavior.
• Strengthen edge security through DDoS detection and mitigation, WAF and abuse-mitigation policy, tenant isolation, and defenses against application-layer attack patterns.
• Integrate and tune Azure Front Door and related edge services alongside first-party gateway components, deciding which layer should address each problem.
• Instrument ingress so latency, error, and saturation questions can be answered quickly; drive incident response, root-cause analysis, and follow-up improvements.
• Partner with Dynamics 365, Power Platform, and Agent 365 service teams on onboarding, capacity, and traffic-shaping decisions.
• Participate in on-call ownership for the systems built, debug live-site issues, and improve systems after incidents.
• Raise the engineering bar through design and code reviews.
