Distributed Systems Architect: Bare-Metal and High-Scale

 Distributed Systems Architect: Bare-Metal and High-Scale 

You will own the architectural blueprints for Analog’s on-premises open-source infrastructure, designing the clustering, replication, and failover topologies across messaging, streaming, and database layers that our DevOps team then automates at scale across client deployments. This is a hands-on, implementation-grade architecture role where the quality of your output directly determines whether a physically isolated or air-gapped client environment survives hardware failure at petabyte scale. 

What You’ll Do 

Open-Source Infrastructure Mapping 

• Map Analog’s Azure PaaS components to open-source equivalents: Event Hub to Kafka/Redpanda, IoT Hub to EMQX, ADX to ClickHouse or Apache Druid, and Blob Storage to Ceph/MinIO 
• Produce side-by-side equivalence assessments documenting feature gaps, operational differences, and migration risk for each component transition 
• Validate client hardware specifications and assess compliance with air-gap security requirements prior to each deployment 

Cluster and Topology Design 

• Design multi-node clustering, rack-aware replication, and quorum topologies for bare-metal Kafka/Redpanda and PostgreSQL (Patroni) clusters 
• Design resilience protocols for hardware and network switch failures in physically isolated or air-gapped client environments 
• Architect RocksDB state backend tuning for stateful Apache Flink workloads, including compaction strategy, block cache sizing, and write-ahead log configuration 

Linux and Hardware Optimization 

• Tune Linux kernel parameters, NUMA bindings, network ring buffers, and NVMe I/O scheduler configurations to eliminate hardware bottlenecks under petabyte-scale write workloads 
• Define CPU affinity, IRQ balancing, and huge page configurations for latency-sensitive broker and database processes 
• Author reproducible benchmark harnesses to validate configuration changes against client hardware before production rollout 

Blueprints and DevOps Enablement 

• Deliver precise, implementation-ready configuration blueprints and runbooks for Terraform and Ansible automation, documents the DevOps team can execute without architectural interpretation 
• Maintain a library of parameterized reference architectures covering single-rack, multi-rack, and geographically distributed bare-metal topologies 
• Conduct pre-deployment reviews of client hardware specs and provide go/no-go assessments with remediation guidance 

What You’ll Bring 

• 10+ years architecting and operating distributed infrastructure at TB to PB scale in production environments 
• Expert-level Kafka or Redpanda clustering: partitioning strategy, ISR tuning, consumer group management, compaction policies, and operational lifecycle at scale 
• Deep Linux systems engineering: kernel networking subsystems (TCP buffer tuning, interrupt coalescing), storage fabrics, and NUMA-aware process binding 
• Proven track record deploying HA database clusters without cloud load balancers: Patroni, Pacemaker, or equivalent in production 
• Experience deploying software-defined storage (Ceph, MinIO) on physical hardware in production, including CRUSH maps, erasure coding, and performance tuning 
• Ability to produce implementation-ready blueprints and runbooks; your output must be directly actionable by a DevOps automation team without architectural interpretation 

About Analog 

Analog builds industrial intelligence infrastructure for the physical world. We deliver high-throughput data pipelines, real-time analytics, and edge-to-cloud connectivity for mission-critical environments where cloud dependency is not an option. Our clients operate in regulated, air-gapped, and physically demanding settings and they depend on us to get the infrastructure right from day one. 

This is a full-time, on-site role.
