Data Scientist

Job Description This is a remote position. Join one of the Philippines' fastest-growing tech companies! Open to Philippine-based candidates only. Company Overview Full Scale is a tech services company that helps businesses build dedicated teams of skilled software engineers. We make finding and retaining experienced software talent easy and affordable. Position Summary We are looking for a Senior Data Scientist with an agentic AI focus to join our growing team. You will design, build, and productionize both predictive models and LLM agents for a US-based client in the automotive retail space — a real-time platform where voice calls, customer data, and AI agents come together to power live customer conversations. This is not a notebook-to-engineering-handoff role. The data layer already exists (AWS lakehouse, Databricks, Gold-zone datasets). The ML services already run. We're hiring the scientist who will make them think — building multi-step agents with tool access to dealership systems, owning the evaluation infrastructure, and shipping models that drive real business outcomes. Key Responsibilities Design, build, and evaluate LLM agents that operate against real dealership systems — booking service appointments, answering vehicle availability questions, resolving customer identity, and escalating to humans with full context. Own the tool-use layer: define the tools and function schemas agents call, the guardrails around each, and how the system fails when a downstream service is slow or unavailable. Build agent evaluation infrastructure — offline eval sets, adversarial and edge-case suites, live A/B testing, and regression gates that block deployment on quality drops. Design and implement escalation logic and confidence thresholds: where the agent acts, where it confirms, and where it hands off to a person. Develop and maintain RAG systems over dealership content (service history, OEM documentation, policy, inventory) using Bedrock embeddings, pgvector on Aurora, and OpenSearch Serverless. Own prompt architecture, versioning, and change control as a first-class engineering artifact under source control. Build, validate, and deploy predictive models on lakehouse data — gross profit forecasting, customer lifetime value, defection risk, next-service prediction, identity resolution, and inventory pricing signals. Own the full model lifecycle: feature engineering, training, validation, deployment, monitoring, and retraining. Ship models with drift and degradation monitoring from day one. Convert business questions from operations and ownership into well-posed modeling problems and push back when a question is better answered with a query than a model. Quantify and communicate model impact in dealership terms: gross, units, retention, CSI, labor hours saved. Requirements 4+ years applying data science in production, with models that made real decisions and had real consequences. Strong Python and SQL. You write code others can run and maintain. Hands-on experience building LLM agents with tool use and function calling — not just prompt engineering. Be ready to walk through a system you built and how you evaluated it. Practical RAG experience: embeddings, vector search, chunking, retrieval evaluation, and re-ranking. Sound statistical fundamentals and honest handling of uncertainty. We prefer a well-calibrated interval over a confident point estimate. Experience deploying models to production — not handing notebooks off to an engineering team. Working comfort with AWS ML tooling (Bedrock, SageMaker, Lambda) and a lakehouse or data warehouse environment. Nice to Have Databricks, Spark, and Delta Lake experience. Experience with agent frameworks, orchestration patterns, and structured output / JSON-mode reliability. Voice AI or conversational systems experience (Retell, Vapi, or comparable), including latency constrained design. Time-series forecasting and causal inference exposure. Automotive retail domain knowledge — DMS, CRM, F&I, fixed operations. A candidate who understands what an RO or a chargeback is will ramp faster. Familiarity with AI safety and evaluation practice, including handling of PII in prompts and logs. Benefits Why join us: Fully remote – work from anywhere in the Philippines. Work on live agentic AI systems — not POCs, not slideware, not handoff-to-engineering. Data layer already in place (AWS lakehouse, Databricks) so you can focus on modeling and agents, not plumbing. Small, senior, high-autonomy team with documentation-first culture. Opportunity to define the evaluation and deployment standards every new model and agent will follow. A team environment that values intellectual honesty, technical depth, and follow-through.
