About the Job

Requirements

  • Proven experience shipping production AI or backend systems in a high-ownership environment, with a recent focus on large language model-powered applications.
  • Expertise building retrieval systems using retrieval-augmented generation and hybrid search, including chunking and indexing strategy, embeddings, vector and lexical search, reranking, and measuring retrieval quality.
  • Expertise building developer tooling that lets developers build production agents, which can include frameworks for multi-agent orchestration, an agent and tool registry, and shared infrastructure for tracing and evaluation.
  • Experience owning platform initiatives from design through adoption, across systems such as retrieval and indexing, large language model provider integrations, and agent orchestration, including driving adoption and evolving the platform as usage grows.
  • Demonstrated technical leadership: leading significant projects, designing solutions for non-trivial problems by weighing tradeoffs, and influencing architecture and execution beyond the immediate workstream.
  • A strong track record delivering complex projects with multiple stakeholders, dependencies, or phases.
  • Strong backend engineering fundamentals and proficiency in languages such as Ruby on Rails, Python, JavaScript, or Go, with SQL and relational database management system experience.
  • Hands-on experience with the artificial intelligence application lifecycle: experiment setup, dataset curation, offline evaluation, error analysis, deployment, and online evaluation.
  • Ability to frame problems, propose solutions, and align others in ambiguous situations.
  • Ability to explain technical ideas to technical and non-technical audiences and translate complex concepts into business impact.
  • Ownership mindset and bias for action, raising the bar for the team through mentoring, code review, and personal contributions.
  • Curiosity, continuous learning, and an agent-forward approach to building software.

Responsibilities

  • Lead retrieval initiatives end to end by designing, building, and operating retrieval systems using retrieval-augmented generation and hybrid search, including lexical and vector search, reranking, and filtering, so agents answer from the right content with appropriate context; own delivery from scope and design through launch, monitoring, and iteration.
  • Drive technical design for the frameworks and platform components engineers use to build production agents, including multi-agent orchestration and shared primitives for prompts, tools, tracing, and evaluation.
  • Diagnose thin, incorrect, or inconsistent answers by separating retrieval problems from generation problems such as prompts, token budgets, and model choice; set a testable quality bar and lead work to improve answer quality.
  • Define how documents, knowledge bases, and call transcripts are ingested, segmented, labeled, and retrieved, including primitives for freshness, deduplication, source precedence, and internal versus external visibility.
  • Build evaluation, observability, and rollout practices—including offline evaluations, online monitoring, and regression detection—to enable safe changes to prompts, models, and retrieval; evaluate solution paths and determine when to trust, redirect, or override model and agent output.
  • Define and track performance and scaling targets for retrieval and indexing, large language model provider usage, and agent orchestration.
  • Ensure the reliability and performance of owned systems; participate in on-call, lead incident resolution for the area, and communicate with the team and stakeholders during incidents.
  • Use coding agents by default for implementation, testing, refactoring, and documentation while maintaining a high validation bar; create reusable workflows, patterns, and tooling that increase team effectiveness.
  • Work with product, design, and engineering leadership to shape roadmaps, tradeoffs, and requirements, and translate strategy into concrete execution plans.
  • Mentor engineers, provide code review and technical guidance, and improve standards, tooling, and processes.

Desired Qualifications

  • Experience with pgvector or other vector indexes and query performance at scale.
  • Experience with content ingestion from third-party systems, including document stores, knowledge bases, and customer relationship management knowledge objects, and related lifecycle problems such as sync state, deduplication, and source conflicts.
  • Experience processing conversation or call transcripts, including handling personally identifiable information and consent constraints.
  • Experience designing evaluation suites that score qualities such as thoroughness and faithfulness, not only correctness.
  • Experience with voice or real-time conversational agents.
  • Experience with enterprise software as a service, especially business-to-business marketing or sales technology, or Salesforce/customer relationship management integrations.
  • Startup experience and rapid shipping.
