  • Optimize performance & reliability for high-concurrency voice interactions (latency budgets, error budgets, observability)
  • Measure what matters: set up metrics for containment/conversion, latency (p95), and cost per successful task
  • Raise the bar: code reviews, design docs, mentoring, and contribution to on-call with clear SLOs
  • Champion best practices in technical product development, scalability, and system design

Good to have

  • Experience with AI agents: Prior experience building and scaling AI agents based on modern LLMs
  • Scripting and Automation: Proficiency in scripting languages and automation tools
  • Advanced AWS Services Knowledge: Expertise in AWS technologies beyond the basics, such as AWS ECS, EKS, and Fargate

Desired Candidate Profile

Bachelor s degree in Computer Science, Engineering, or related technical discipline (or equivalent experience).

  • Highly motivated software engineer/ developer with 5+ years of software engineering experience, with hands-on work in ML/AI systems
  • Profound knowledge of JavaScript/TypeScript with a focus on building serverless and containerized applications
  • Outstanding problem-solving skills and the ability to thrive under operational pressure
  • AI-First mindset: Actively using Cursor/Windsurf or similar tools to accelerate software development, with an understanding of prompt engineering and agentic systems
  • Strong interest in LLMs, agents, and applied GenAI in real-world environments
  • Clear, concise communication; ability to turn ambiguous goals into stable designs
