The Work    

Are you an experienced Site Reliability Engineer who thrives at the intersection of software engineering and production operations? Do you take pride in keeping mission-critical customer systems reliable under real-world operational pressure? Are you looking for an opportunity to own production reliability for a modern hybrid infrastructure platform spanning cloud, colocation, and edge environments?  

If so, we have an exceptional opportunity for you.  

Climavision is seeking a Senior Site Reliability Engineer to contribute towards reliability, operational excellence, and production resilience for our customer-facing platform and weather data services. This role is focused on ensuring our systems consistently meet demanding customer SLAs, including a 99.5% availability commitment for radar-derived data services. A central focus of this role is establishing multi-replica and multi-cluster high availability across our .NET services, including hands-on refactoring of C# code to make services safe to run as multiple instances and across clusters.  

This is a hands-on engineering role for someone who is equally comfortable debugging production .NET services, troubleshooting Kubernetes clusters, leading incident response, and improving operational maturity across the organization. The successful candidate will combine strong software engineering experience in C# / .NET with deep production operations expertise and a disciplined approach to reliability engineering.  

Climavision operates a hybrid infrastructure footprint spanning Microsoft Azure, colocation data centers, and edge Kubernetes clusters, deployed alongside weather radar systems. This role will drive production reliability across Azure, colocation, and edge environments.  

35% Production Reliability Engineering   

30% Application Reliability & .NET Service Architecture  

20% Kubernetes Platform Reliability/Operations  

15% Observability, Automation, and Operational Excellence  

Primary Responsibilities: 

• Own production reliability for Climavision’s customer-facing platform and radar-derived weather data services across Azure, colocation, and edge Kubernetes environments.  
• Contribute to the definition and improvement of SLIs, SLOs, alerting standards, and operational metrics used to measure platform reliability.  
• Support and coordinate production incident response efforts, including troubleshooting, mitigation, communication, and postmortem analysis.  
• Diagnose and resolve complex production issues across application services, Kubernetes infrastructure, storage, and distributed systems.  
• Drive multi-replica and multi-cluster high availability across Climavision’s .NET services. This includes working directly in the C# codebase to refactor services that are not currently safe to run as multiple replicas, addressing in-process state, sticky scheduling assumptions, non-idempotent operations, race conditions, and other patterns that prevent safe horizontal scaling, so that services can be deployed with multiple replicas, across multiple clusters, for high availability.  
• Contribute to the multi-cluster high-availability strategy across Climavision’s hybrid fleet, including active-active and active-passive failover behavior, traffic routing, data replication considerations, and graceful degradation when a cluster becomes unavailable.  
• Operate and improve Climavision’s self-managed Kubernetes platform spanning cloud-hosted, colocation, and edge clusters with a focus on availability, resiliency, recovery and operational performance  
• Ensure Kubernetes platform lifecycle activities including upgrades, patching, cluster health, node management, and production change management, are executed in a manner that preserves service availability and minimizes customer-facing risk  
• Improve reliability and operational maturity of production platform services, including observability, autoscaling, ingress, and distributed storage. Partner with the teams responsible for the underlying networking and security primitives rather than owning those areas directly.  
• Design and validate Kubernetes workloads for resiliency, scalability, and operational efficiency, including autoscaling behavior, workload placement, resource management, and graceful degradation strategies.  
• Read, debug, and contribute production-quality C# / .NET code focused on reliability improvements, multi-replica safety, instrumentation, operational tooling, and performance optimization.  
• Partner with software engineering teams to improve production readiness, resiliency patterns, deployment safety, and operational visibility before services reach production. Champion multi-replica-safe design patterns as new services are built.  
• Maintain and improve deployment pipelines, Helm charts, Kubernetes manifests, and infrastructure automation supporting safe and repeatable production releases.  
• Support and evolve Climavision’s observability platform, including metrics, logging, distributed tracing, dashboarding, and alerting.  
• Conduct performance engineering and capacity-planning efforts for customer-facing services during peak weather-event demand.  
• Help facilitate blameless postmortem reviews and drive operational follow-up items through completion.  
• Improve disaster recovery, failover, and business continuity capabilities across cloud, colocation, and edge environments.  
• Drive operational excellence initiatives, including automation, reduction of operational toil, game days, production readiness reviews, and reliability best practices.  
• Contribute as a senior technical resource and mentor on reliability engineering and production operations practices.
