Full Job Description

đź“‹ Description

  • • Own the inference and orchestration layer that powers every AI interaction in the product, sitting between large language models and end users across mobile and desktop clients.
  • • Build and operate production backend systems that serve AI-powered features with high reliability, low latency, and high throughput under real-world usage conditions.
  • • Design inference pipelines, orchestration layers, and clear service boundaries around LLMs, embeddings, and multimodal models to ensure stable and scalable AI behavior.
  • • Optimize latency and throughput across inference, caching, batching, and streaming mechanisms to improve user experience and system efficiency.
  • • Implement and maintain production monitoring, logging, alerting, and incident response systems to ensure rapid detection, diagnosis, and resolution of AI-related outages or degradation.
  • • Develop and manage stable, well-documented APIs that enable seamless integration between frontend clients, ML systems, and external tools.
  • • Operate systems that handle multi-step reasoning, persistent context, and real-world task completion despite non-deterministic model behavior.
  • • Collaborate with cross-functional teams to translate model capabilities into reliable, observable, and user-facing AI features.
  • • Iterate on system performance and reliability based on real usage data, production incidents, and user feedback to continuously improve system outcomes.
  • • Work with Python and Node.js to develop scalable backend services, leveraging PyTorch for model integration and deployment.
  • • Deploy and manage containerized services using Docker and orchestrate them at scale with Kubernetes in production environments.
  • • Integrate with external AI providers including OpenAI, Anthropic, and open-source LLMs, ensuring cost-efficient and reliable model usage.
  • • Manage data persistence and retrieval using both SQL and NoSQL databases to support persistent context and long-running workflows.
  • • Debug and resolve complex issues in distributed systems under high load, with a bias toward shipping and learning from real production behavior.
  • • Contribute to a high-talent-density team that makes collective decisions, moves rapidly, and balances quality with speed in product development.
  • • Execute independently with structure and judgment, contributing to a culture focused on building a truly magical AI product for everyday users.

🎯 Requirements

  • • Strong backend engineering fundamentals in production environments
  • • Experience running high-throughput, low-latency services
  • • Familiarity with AI inference patterns (LLMs, embeddings, multimodal)
  • • Comfortable debugging distributed systems under load
  • • Bias toward shipping and learning from production behavior
  • • Proficiency in Python and Node.js

🏖️ Benefits

  • • Opportunity to build AI systems that bring practical benefits to billions globally
  • • Work in a high-talent-density, hands-on team with collective decision-making
  • • Rapid iteration and learning culture with emphasis on real-world impact
  • • Transparent and efficient interview process with prompt decision-making
