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.
Spectrum collects data from an organization'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 – one that'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.
A resident of JetBrains' startup incubator, Spectrum enjoys startup speed and autonomy, and is backed by 25 years of developer
tooling expertise. We are looking for a Senior ML Researcher to develop the core methods that make Spectrum possible – novel
approaches to temporal ontology extraction, contradiction detection, and semantic alignment across heterogeneous software
artifacts. You will help define and execute the research agenda, while also collaborating with JetBrains Research and external
academic advisors.

Du fühlst dich angesprochen – auch wenn nicht jedes Kästchen ein Häkchen bekommt? Meld dich bei uns. Lass uns quatschen und schauen, ob es passt! SO TICKT SIPGATE * Wir sind von Kopf bis Fuß agil und das nicht nur auf dem Papier. Wie wir arbeiten, siehst du hier. * Wir haben flache Hierarchien und Peer-Verantwortung ist unser Credo – das bedeutet: Verantwortung übernehmen, eigene Entscheidungen treffen und aufeinander acht geben stehen hoch im Kurs. * Wir haben ein transparentes Gehaltsmodell und keine individuellen Gehaltsverhandlungen. Wie genau das funktioniert erfährst du hier. * Nachhaltigkeit ist für uns wichtig – unser Fuhrpark besteht nur aus E-Autos, private Autos laden während der Arbeitszeit kostenlos, wir beziehen unseren Strom von der Solaranlage, wir essen bio und regional und versuchen Verschwendung zu vermeiden. * Wir glauben fest an unser ‘Come as you are’-Prinzip und befinden uns auf der Reise sipgate so inklusiv zu gestalten, dass wir Menschen aller Geschlechter, ethnischen Herkünfte, Körperformen und sozialen Hintergründe herzlich willkommen heißen, Teil unseres Teams zu werden.
