We’re seeking a Sr. Software Engineer, AI to join our team

What You’ll Do:
- Use AI-assisted development tools, including Claude Code, to accelerate implementation while validating correctness, security, and performance.
- Design and build server-side APIs that authenticate users, accept and manage backups, handle large-scale data operations, and prepare restored data for customers across our general user base.
- Collaborate with Product, QA, and Support teams to ensure both backend features reflect real customer workflows and usage patterns.
- Build and maintain support tooling to help diagnose and resolve customer issues at scale.
- Ensure all code and open source assets meet high standards for testing, documentation, reproducibility, and developer usability.

- AI coding agents such as Claude Code, Cursor, Codex, and Antigravity
- Backblaze B2 SDKs and REST APIs
- Open source AI frameworks and tooling (e.g. LangChain, LlamaIndex, vector databases)

The Right Fit:
- 5+ years of backend software engineering experience, ideally on systems that serve millions of users across multiple platforms.
- Proficiency in one or more backend languages (Java, Python, TypeScript, or similar); comfortable picking up new languages as needed.
- Practical understanding of AI workflows — data ingestion, preprocessing, inference, and agent-based orchestration.
