Staff / Senior Applied Scientist, GenAI & ML Systems Location: Wilmington, MA (US) - Fulltime Onsite About the Role We are hiring a Staff / Senior 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 languages) Proven experience deploying GenAI/ML systems in cloud environments (AWS/Azure/GCP) Experience with scalable inference and service operations: containers, APIs, observability, reliability practices MS/PhD in CS/ML/NLP/Stats (or equivalent applied experience building production systems) TraceLink is committed to providing competitive compensation and benefits to all employees. This is the estimated base salary range for this role and should serve only as a guide. Final compensation offered may vary based on a variety of factors including but not limited to experience level, fit for the role, skills, domain knowledge, internal equity, budget, and location.
