Sr. Software Engineer

About Backblaze Backblaze provides reliable, high-availability cloud storage trusted by consumers, SMBs, enterprises, and developers in over 150 countries. Backblaze B2 Cloud Storage supports data-intensive workloads including backup, media, analytics, and modern AI pipelines. Our teams focus on building secure, durable, scalable systems with a strong emphasis on application security from day one and protecting customers to keep them safe. But while there is a lot to celebrate in our past, there is almost as much opportunity ahead of us.

We are hiring a Sr. Software Engineer to join our Organization Services team. This team builds the core backend services that power how customers model, manage, and secure organizations in Backblaze. That includes organization and account lifecycle management, identity and access foundations, and a modern role-based access control system that governs access to resources at scale.

About the Role In this role, you will design and build highly available backend services and APIs in our Kotlin/Java ecosystem and will work on front-end applications written in React and Typescript. You will work on systems that sit at the center of customer administration, authorization, and resource orchestration, with design challenges shaped by ideas found in platforms such as AWS IAM, GCP IAM, and Azure RBAC. This is a strong fit for an engineer who enjoys building foundational platform capabilities, can reason rigorously about security and correctness, and is comfortable owning complex systems through design, implementation, rollout, and operation.

We also value engineers who use modern AI tools effectively to accelerate development, improve design quality, and strengthen security and maintainability.

Responsibilities:

• Design, build, and evolve scalable backend services and APIs in Kotlin and Java, with strong attention to performance, reliability, and long-term maintainability.
• Develop core platform capabilities, including organizational resource hierarchies and access policies.
• Partner with adjacent platform and product teams to integrate with authentication, storage, billing, and other shared systems.
• Write technical designs, break down ambiguous problems, and drive projects from concept through production rollout.
• Own the full delivery lifecycle for the systems you build, including schema design, migrations, testing strategy, deployment, observability, and operational readiness.
• Diagnose and resolve complex production issues involving distributed services, MySQL/Vitess, and cross-service dependencies.
• Improve system security, correctness, and developer velocity through thoughtful design, automation, and use of modern AI-assisted engineering tools.
• Contribute to engineering excellence through code review, design review, mentoring, and raising the technical bar across the team.
• Collaborate cross-functionally with Product, Security, QA, Support, Finance, and other partners to translate business and operational requirements into robust technical solutions.
