QA Performance Engineer (YouTrack)

<div>
 Software engineers and AI agents alike suffer from the same problem: finding that one person or place that will answer their tough, specific question. Many solutions promise to solve this with similarity search in vector databases. Unfortunately, finding the answer is often a puzzle with pieces to be collected across a myriad of contradictory sources and cannot be solved without surgical search and careful reasoning.
 <br/>
 <br/>
 Spectrum collects data from an organization&rsquo;s code, docs, and issues, and organizes knowledge in a unified ontology that AI agents can efficiently search through and reason over. We aim to revolutionize the semantic layer space for software-building organizations and move beyond specs that fall out of sync with code, introducing a living spec &ndash; one that&rsquo;s extracted from the whole system and used to keep it aligned. Spectrum is meant to be the single source of truth for all product and architectural knowledge.
 <br/>
 <br/>
 Spectrum is a resident of JetBrains' startup incubator, with startup speed and autonomy, and backed by 25 years of developer tooling expertise. We are looking for a top-class ML Engineer who will help us shape the future of software development. You will own our AI and ML engineering stack and help define the research agenda for our team.

  <li>
   Creating the datasets, metrics, and pipelines that drive measurable improvements across the system.
  </li>
  <li>
   Architecting and improving agents for context retrieval, knowledge extraction, and data alignment, which includes prompt engineering, model selection, and inference optimization.
  </li>
  <li>
   Establishing MLOps practices, including orchestration, observability, and experiment tracking.
  </li>
  <li>
   Collaborating with the engineering team on system design and with JetBrains Research on the research agenda.
  </li>
  <li>
   Defining hiring criteria, growing the ML team, and shaping the ML team culture.
   <br/>
   <br/>
  </li>
 </ul>
 <strong>
