What you'll do

As a Software Engineer at Viasat, you will be at the forefront of a new era of software development. You won't just be writing code; you will be "teaching" and guiding AI models to transform existing codebases. This role focuses on utilizing Claude (Anthropic) to analyze, refactor, and document legacy code, ensuring our systems are scalable, efficient, and maintainable.

The day-to-day

• AI-Driven Refactoring: Use Claude to identify patterns in legacy codebases and generate refactored versions that adhere to modern design patterns and clean code principles.
• Prompt Engineering: Develop and refine sophisticated prompts to ensure the AI generates high-quality, secure, and context-aware code improvements.
• Validation & Testing: Implement a "Human-in-the-Loop" workflow by rigorously reviewing AI-generated code and writing comprehensive unit tests to ensure functional parity between old and new systems.
• Documentation: Utilize LLMs to automatically generate technical documentation, API schemas, and architectural diagrams from existing source code.
• Performance Optimization: Identify bottlenecks in current software and work with Claude to suggest and implement algorithmic improvements.
• Collaboration: Work closely with senior architects to ensure that AI-refactored code aligns with the long-term technical roadmap.
