<li>Evaluate and implement strategies for model selection (OpenAI, Anthropic, or Open Source like Llama 3) based on latency, cost, and performance requirements.</li>
<li>Develop high-performance Python backends (FastAPI or Flask) to serve AI features to our global user base.</li>
<li>Build robust evaluation frameworks to measure LLM accuracy, reduce hallucinations, and monitor production performance using tools like&nbsp;LangSmith&nbsp;or&nbsp;Arize Phoenix.</li>

<li>Deep knowledge of PostgreSQL or MySQL, specifically in writing complex ActiveRecord queries, optimizing indexes, and managing database migrations safely at scale.</li>
<li>Extensive experience managing background jobs, race conditions, and heavy data processing using Sidekiq and Redis.</li>
<li>A strict habit of writing maintainable test suites using RSpec, Capybara, or FactoryBot to ensure high test coverage and stable deployments.</li>
<li>Proven track record of designing, securing, and documenting clean RESTful APIs.</li>
<li>Solid understanding of Git workflows, Docker containerization, and asset compilation pipelines (Propshaft, Webpacker, or Vite Ruby).</li>
</ul>

<li>Familiarity with cloud platforms (AWS, Heroku, or Render) and CI/CD pipelines.</li>
<li>Understanding of domain-driven patterns within Rails to keep large codebases decoupled.</li>
<li>Knowledge of web security best practices (OWASP Top 10, cross-site scripting prevention).</li>
</ul>
&nbsp;
&nbsp;
Responsibilities:
<ul>
