About Profound

Profound is on a mission to help companies understand and control their AI presence. As an AI/ML Engineer, you will design, build, and ship large-scale NLP and LLM systems that power classification, ranking, clustering, topic discovery, and content generation. You will own workflows from data to deployment, partner across product and engineering, and turn real user conversations into production features and publish-ready content that drive visibility, engagement, and conversion.

What You’ll Do

  • Build and deploy NLP models at scale for classification, ranking, clustering, topic extraction, and summarization.
  • Design LLM workflows for context and content generation end-to-end: topic discovery → brief creation → outlines/drafts → revision loops → publish-ready assets.
  • Develop prompt and template libraries aligned to brand voice and channel (blog, landing pages, help docs, ads), with retrieval for evidence-grounded generation and citations.
  • Create eval frameworks for generated content (factuality, coverage, tone, safety, originality) with rubric-based LLM evals, human-in-the-loop review, and red-teaming.
  • Instrument content performance (AEO/SEO visibility, engagement, conversion) and run experiments to improve quality, cost, and latency.
  • Transform large text datasets into production features and signals that drive product insights.
  • Partner with engineering to instrument events, maintain data pipelines, and uphold high data quality and observability.
  • Collaborate with product, data, and go-to-market on success metrics and experiments that move customer-facing KPIs.

What We Expect from You

  • Proven experience shipping ML systems in production at scale, especially with large text data.
  • Hands-on experience building LLM content systems (prompting, templating, retrieval/RAG, guardrails, evals).
  • Fluency in SQL and strong Python skills with modern ML tooling.
  • Strong grasp of ML and generation quality metrics; ability to design offline/online evals and monitoring.
  • Ability to innovate when off-the-shelf doesn’t fit the problem.
  • Experience working in cross-functional, high-performance teams.
  • Clear communication with technical and non-technical partners.
  • Ownership mindset and comfort operating in a fast-paced environment.

What You’ll Get Out of It

  • Ownership of the entire product analytics function at an early stage company.
  • A key role in shaping how we measure usage and make product decisions.
  • Close collaboration with product, engineering, and go-to-market teams.
  • A fast-paced environment with a lot of trust and autonomy.
  • Competitive compensation and meaningful equity.
