About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

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.
