Full Job Description
Tech Lead - Data Scientist
About the Role

We are looking for a Technical Lead to drive the development of Obsidian's core ontology that powers our groundbreaking unified security config analysis, AI security, and threat detection product.
  • Scale this ontology as part of a team of 3-6 software engineers and data scientists to cover hundreds or thousands more enterprise application platforms. Drive automation of repeatable R&D subtasks.
  • Become an expert on foundational identity, authentication, authorization, network, and data security concepts. An unhealthy dose of curiosity about the design and administration - technology, people, and process - of complex application platforms such as GitHub, Salesforce, and Workday is a must. You will love exploring rabbit holes into esoteric domain knowledge related to these topics.
  • Formulate security problems as data and ML problems, constantly addressing and refining the customer outcome in collaboration with top-flight security teams from Global 1000 companies.
What We're Looking For
  • 6+ years of experience in data science, machine learning, or applied research, preferably with 2+ years in a technical leadership role.
  • A track record of shipping production ML or data systems at scale - ideally systems involving ontologies, knowledge graphs, entity resolution, or semantics over heterogeneous data sources.
  • Expert-level proficiency in Python and modern ML/data tooling.
  • Working knowledge of core security domains, or a strong ability to learn.
  • Experience formulating fuzzy business or security problems as concrete ML/data problems:
    • able to decompose ambiguous, ambitious problems into well-scoped subproblems and design experiments with statistical rigor.
    • comfortable being scrappy and diving deep into vendor documentation, APIs, and audit logs to find the necessary data sources
  • Excellent written and verbal communication skills; ability to engage credibly with technical security practitioners at large enterprises.
