AI Frameworks AI-assisted coding tools

Job description

  • Design and build AI-powered features — LLM agents, retrieval, and event intelligence — that operate on high-volume, real-time event streams, from problem framing through production deployment and monitoring.
  • Architect and own the systems behind them: agent and prompt orchestration, retrieval pipelines, tool/API integrations, and low-latency inference and evaluation at scale.
  • Reason about consistency, throughput, fault tolerance, and cost across services that must stay reliable under bursty, unpredictable load.
  • Take AI features from prototype to production, establishing the evaluation, guardrail, observability, and improvement loops that keep them accurate and trustworthy over time.
  • Partner with platform, product, and applied-research teams to define what “good” looks like and to integrate AI cleanly into existing services.
  • Raise the bar through example, reviews and mentorship, and help shape the team’s technical direction.


Requirements

What you’ll bring

  • 5+ years of software engineering experience, with meaningful time spent building and operating production distributed systems (high-throughput services, streaming/event-driven architectures, or large-scale data platforms).
  • Hands-on experience building and shipping AI systems in production — LLM-powered applications, agents, or retrieval — including the surrounding orchestration, serving, and evaluation, not just prototypes.
  • Strong programming fundamentals and comfort moving between systems and AI/application code.
  • Solid grounding in applied AI fundamentals: prompting, retrieval, agent patterns, and how to evaluate and guardrail LLM behavior.
  • Experience with cloud infrastructure (AWS, GCP, or Azure), containers, and orchestration (Kubernetes).
  • A pragmatic, reliability-minded mindset: you optimize for systems that work correctly at scale, and you can articulate the trade-offs behind your choices.
  • Strong communication and collaboration skills, and a track record of raising the quality of the teams and systems around you.

Nice to have

  • Experience with LLMOps tooling and patterns — evaluation harnesses, prompt/version management, tracing and observability for agents, and online/offline eval consistency.
  • Deep experience serving LLM-based systems in production, including retrieval-augmented generation, multi-step agents, and tool use.
  • Background in anomaly detection, event correlation, or applied problems in observability, AIOps, or reliability.
  • Familiarity with the ecosystem — e.g. LLM APIs and frameworks such as LangChain or LlamaIndex, vector databases, and distributed data/compute tools such as Kafka, Airflow, or Spark.
  • Contributions to open-source AI or distributed-systems projects.
