ABOUT THE ROLE
ABOUT THE ROLE
ABOUT THE ROLE
As a Principal Software Developer at Astrus, you’ll help define the technical foundation of our platform and push the limits of what’s possible in large-scale AI and engineering systems. This is an open Principal Software Developer role: we are looking for world-class builders who can bring deep technical leadership, a passion for elegant systems, and the ability to solve some of the hardest scaling and performance problems in modern software.
This is a high-leverage role for someone who thrives on both architecture and execution, who sets the bar for technical excellence, and who can bring clarity and momentum to hard, ambiguous problem spaces.

WHO YOU ARE
WHO YOU ARE
WHO YOU ARE
10+ years of experience building and scaling production systems.
Deep expertise in software architecture, distributed systems, and performance optimization.
Fluency in at least one major programming language (we lean on Python, Rust, Go, and TypeScript). Strong fundamentals matter more than any specific stack.
Experience leading technical design from ambiguity → clarity → execution.
Strong sense for developer experience, code health, and long-term maintainability.
A collaborative mindset: you value speed, clarity, and candor, and thrive in interdisciplinary teams.
