Set the bar for clean, well-tested code, and mentor others in the team.
Develop and deploy robust software for cloud and local environments.
Evaluate, integrate, deploy, and optimize AI tools and services.
Mentor others and help shape our work as the team grows.

Requirements

Several years of experience building backend or systems software, preferably in agile environments.
Strong skills in Rust and/or modern C++.
A team player's instinct for fast-moving, cross-disciplinary work.
Sound design judgment and a knack for clean, well-tested code.
A pragmatic approach to debugging and large, existing codebases.
Solid understanding of distributed systems, network protocols, and asynchronous runtimes.
Experience with database engines (MariaDB, Postgres, NoSQL).
Familiarity with cloud infrastructure and on-premise/local server environments.
Experience designing and consuming APIs (REST, gRPC, or similar).
Hands-on AI experience: integrating, deploying, or building AI-powered systems.
