[Remote] Senior Software Engineer - Data Infrastructure

Note: The job is a remote job and is open to candidates in USA. Backblaze is hiring a Senior Software Engineer to build and improve the data infrastructure platform supporting its B2 Object Storage and Computer Backup products. The role focuses on automation, observability, system stability and throughput, and architectural changes that support the long-term needs of the service.

Responsibilities

• Design and build automation frameworks that let other engineers provision, configure, and repair fleet infrastructure themselves
• Design and extend the observability stack (metrics, logs, traces, alerts) that tells us whether the storage platform is healthy and where it is degrading
• Build reporting, dashboards, and visualizations that give engineering and leadership a clear view into fleet health, capacity, and operational trends
• Build system health tooling that detects failing hardware, drifting configuration, and capacity risk before they turn into incidents
• Lead technical design discussions and produce clear design documents for changes that span multiple services and teams
• Drive the implementation of large features from design through rollout, including the migration and backfill work that real systems require
• Partner with the on-call rotation to turn recurring toil and incident findings into automation and better signal

• Experience designing automation frameworks or platforms that other engineers build on
• Experience building large scale software systems running on thousands of servers
• Experience building automation or tooling that other engineers depend on daily, whether internal platform services, operational tooling, or a deployment and configuration pipeline
• Working knowledge of an observability stack (Prometheus, Grafana, OpenTelemetry, ELK, Datadog, or equivalent), including instrumenting a service and designing alerts people trust
• Strong Linux fundamentals and comfort operating in a bare-metal or hybrid environment rather than a fully managed cloud
• Professional experience incorporating AI-assisted development tools (Gemini, Cursor, Claude Code, or similar)
• Comfortable with all aspects of the software development lifecycle, including design, implementation, testing, and rollout

• Experience designing SLOs and error budgets, or reducing alert noise on a fleet running at scale
• Experience with time-series databases and query languages such as PromQL
• Experience automating hardware lifecycle work: burn-in, failure detection, drive replacement, decommissioning
• Experience with discovering and implementing performance improvements, including CPU and IO
• Understanding of Linux internals and file systems
• Familiarity with hard drive performance and optimization, including host-managed SMR
• Experience building and interpreting models, dashboards, or reports
