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 durable, scalable systems with a strong emphasis on developer experience and operational efficiency.

But while there is a lot to celebrate in our past, there is almost as much opportunity ahead of us. We’re seeking a 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 global 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.

Tools and Technologies

• AI coding agents such as Claude Code, Cursor, Codex, and Antigravity
• Languages: Python, TypeScript, Go, JavaScript, Java (and other languages common in the open source ecosystem)
• Backblaze B2 SDKs and REST APIs
• Open source AI frameworks and tooling (e.g. LangChain, LlamaIndex, vector databases)
• SQL and NoSQL backend development (experience with large-scale distributed databases a plus)
• GitHub, pytest, CI/CD pipelines
• Large-scale server infrastructure (Linux, cross-platform awareness)

The Right Fit:

• 2+ 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.
• Experience building or working with large-scale APIs and distributed storage or data systems.
• Production-quality coding habits: rigorous testing, clear documentation, and attention to security and performance.
• Customer-focused mindset — you think about the developer and end-user experience in everything you build.
• Strong written communication skills; you can explain technical decisions clearly to both engineers and non-engineers.
• Good attitude, cross-functional collaboration skills, and a genuine desire to work in a fast-paced environment with evolving requirements.

Bonus Points For:

• Experience building or evaluating AI agents and multi-step tool-use systems.
• Experience with Cassandra or other large-scale NoSQL systems.
• Familiarity with ReactJS or front-end frameworks.
• Prior work with vector databases or embedding pipelines.

Responsibilities:

• Design, implement, and maintain B2 and S3-compatible APIs to ensure correctness, performance, and backward compatibility for a large base of external customers and integrations.
• Lead technical design discussions and produce clear design documents
• Instrument services, develop metrics, define meaningful SLIs/SLOs, and drive reliability improvements.
• Actively participate in on-call rotation to help determine incident root causes and identify follow-up remediation items

The Right Fit:

• 7+ years of server-side Java programming experience
• Experience writing software for large scale systems, including design, implementation, testing, and rollout
• Communicates proactively in a remote environment by keeping the team informed, surfacing blockers early, and moving work forward
