Our expanding product suite continues to protect patients and now also enhances multi-enterprise collaboration through innovative new applications such as MINT. Tracelink is recognized as an industry leader by Gartner and IDC, and for having a great company culture by Comparably. Applied Scientist, GenAI & ML Systems Location: Wilmington, MA (US) - Fulltime Onsite About the Role We are hiring an Applied Scientist to lead the design and deployment of production-grade GenAI and ML systems with a strong emphasis on being hands-on. You will personally build, iterate, and ship systems focused on LLM/SLM optimization for agentic, multi-agent architectures in cloud environments. This role is ideal for someone with deep expertise in one or more areas of LLM/SLM optimization for agent-based systems, and hands-on experience in designing, implementing, and operating large-scale multi-agent systems in the cloud. Key Responsibilities Hands-on ownership of building and shipping multi-agent systems (planner/executor, tool-using agents, supervisor patterns, routing, role-based agents) from prototype to production. Write production-quality code for agent orchestration, tool integration, memory/state design, and context management. Lead context engineering strategies for multi-agent coordination: prompt design, state persistence, agent handoffs, grounding, constraints, and safety controls. Hands-on fine-tune and deploy SLM models for production usage: dataset creation, training workflows, evaluation, and inference serving. Build Advanced RAG pipelines end-to-end, including semantic search, embeddings, hybrid retrieval, and cross-encoder reranking. Implement evaluation frameworks for multi-agent systems covering quality, latency, cost, robustness, and failure mode detection. Collaborate with platform and product engineering to ensure solutions are cloud-native, secure, observable, and scalable (monitoring, logging, CI/CD). Optimize for cost and latency via model routing, caching, compression strategies, and inference efficiency improvements. Mentor peers through code reviews, architecture sessions, and hands-on technical leadership. Required Knowledge & Experience Context engineering for complex multi-agent systems (prompt orchestration, tool calling, memory/state design, routing, constraint handling) Fine-tuning of SLMs and delivering them to production (training strategies, validation, deployment, monitoring, rollback readiness) Experience with Advanced RAG, semantic search, embeddings, and cross-encoders (retrieval tuning, chunking strategies, query rewriting/planning, reranking) Ability to translate ambiguous requirements into concrete architectures, metrics, and deliverables Hands-on inference optimization experience: quantization, distillation, batching, caching, model routing, speculative decoding Experience building retrieval systems at scale using vector DBs and search stacks Comfort working across the full lifecycle: research → prototype → A/B test → production hardening Preferred Qualifications Familiarity with enterprise constraints: privacy, security, data governance, permissions, auditability Experience designing and running GenAI observability: traces, prompt/versioning, tool call logging, feedback loops Strong ability to implement production-quality systems in Python (and/or adjacent backend language…
