What you need

  • 5+ years of experience as a software engineer, with a track record of shipping and operating production systems.
  • Hands-on experience building generative AI applications: structured outputs, function/tool calling, prompt and context design, RAG, model routing, and handling model failure modes.
  • Genuine enthusiasm for agents and LLMs — you follow the space closely, have opinions on the tools, and can talk shop about the evolving ecosystem.
  • Strong systems fundamentals: APIs, distributed systems, queues, data stores, service ownership, auth, idempotency, retries, and observability.
  • Experience defining evals and measurement for AI systems — offline datasets, online metrics, and knowing when and how to measure a launch quality bar.
  • Fluent with AI coding tools and code-assistant workflows as part of your day-to-day engineering practice.

Nice to have

  • Experience in Ads, marketing technology, marketplaces, growth, recommendations, search, or analytics.
  • Experience building AI systems where mistakes are expensive: customer-facing products, regulated workflows, policy review, payments, or high-scale infrastructure.
  • Experience building internal workflow automation for sales, ops, support, policy, trust, or engineering productivity.

What you get

  • Comprehensive Healthcare Benefits and Income Replacement Programs
  • 401k Match
  • Family Planning Support
  • Gender-Affirming Care
  • Mental Health & Coaching Benefits
  • Flexible Vacation & Reddit Global Days Off

Worth weighing

  • No specific mention of the tech stack beyond generative AI and general programming languages.
  • The role involves significant responsibility in ensuring the reliability and trustworthiness of AI systems, which may be high-pressure.
  • The salary range is provided but may vary based on multiple factors, which could lead to uncertainty in final compensation.
