Full job description

Full-time Applied AI Scientist role, remote in Singapore, mid to senior level requiring a PhD. Responsibilities include analyzing traffic and behavioral data to identify patterns and data quality issues, translating quantitative findings into actionable recommendations, designing and maintaining AI agents and reporting pipelines, partnering with engineering and product teams to ensure data quality, collaborating with AI/ML teams for model improvements, and supporting data needs across Pixalate's product portfolio. Requirements include a PhD in a quantitative field, 3-6 years experience in data science, ML, or analytics, strong statistical foundation, hands-on experience with LLMs and AI agents including prompt engineering and agentic workflows using frameworks like LangChain, proficiency in Python and SQL, critical thinking about data quality and model outputs, and strong communication skills. Benefits include monthly internet reimbursement, casual remote work environment, hybrid flexible hours, advancement opportunities, annual team events, a high-performing team culture, and competitive compensation.

What you'll do

  • Analyze traffic, behavioral, and signals data to identify patterns, anomalies, and data quality issues
  • Translate complex quantitative findings into clear, actionable recommendations for engineering, product, and cross-functional teams
  • Design and maintain AI agents, dashboards and reporting pipelines to track data quality, trends, and product health over time
  • Partner with engineering and product teams to ensure data quality and integrity across product pipelines
  • Collaborate with AI/ML teams to close the feedback loop between QA findings and model improvements
  • Support data needs across Pixalate's product portfolio — including supply-side intelligence, MFA detection, seller/app ratings, and compliance-related products

Requirements

  • PhD in Statistics, Mathematics, Data Science, Computer Science, or a related quantitative field
  • 3–6 years of experience in a data science, ML, or data analytics role
  • Strong statistical foundation — understanding distributions, hypothesis testing, model evaluation, and where things go wrong
  • Hands-on experience building with LLMs and AI agents, including prompt engineering, tool use, and designing agentic workflows using existing frameworks (e.g. LangChain, LlamaIndex, CrewAI, AutoGen, or similar)
  • Proficiency in Python and SQL
  • Ability to think critically about data quality and model outputs — naturally skeptical and rigorous
  • Clear written and verbal communication skills
