• Cutting-Edge Tech: Work with Rails 8, LLMs, and modern tools like Hotwire, Databricks, and xAI’s API in a microservices architecture.
• Autonomy and Influence: Collaborate directly with our CEO and CTO to shape our AI-driven platform, with freedom to innovate.
• Competitive Compensation: $160,000–$200,000 CAD/USD (based on experience) and benefits.
