Senior Machine Learning Engineer

Company Description
It all started in sunny San Diego, California in 2004 when a visionary engineer, Fred Luddy, saw the potential to transform how we work. Fast forward to today - ServiceNow stands as a global market leader, bringing innovative AI-enhanced technology to over 8,100 customers, including 85% of the Fortune 500®. Our intelligent cloud-based platform seamlessly connects people, systems, and processes to empower organizations to find smarter, faster, and better ways to work. But this is just the beginning of our journey. Join us as we pursue our purpose to make the world work better for everyone.
Job Description
What you get to do in this role:
Own the end-to-end lifecycle of models (problem framing → data → training → evaluation → deployment → monitoring).

• Design features and labeling strategies; improve data quality with heuristic and programmatic techniques (e.g., weak supervision, active learning, synthetic data generation via LLMs).
• Train, tune, and compare models (tree-based, linear/GLM, deep learning, seq2seq, recommendation,LLMs) with reproducible pipelines.
• Build and tune approriate information retrieval for RAG use cases (e.g., dense and sparse retrieval), engineering the right context for the task.
• Implement rigorous offline metrics and online A/B experiments; define guardrails and SLOs for quality, latency, and cost.
• Develop efficient API endpoints for model inference and ensure they are scalable and production ready (e.g., containerization, load balancing, auto-scaling, monitoring, logging, alerting, and incident response) and meet product requirements.

Qualifications
To be successful in this role you have:

• Experience with AI developer productivity tools like Windsurf, Cursor, and prompt tuning is required, along with the ability to apply AI techniques to practical engineering problems.
• We are seeking individuals who can quickly prototype, optimize prompts, and develop scalable, impactful AI-driven solutions.
• 5+ years of hands on experience in ML/AI engineering, with a strong focus on building and deploying AI/GenAI applications.
• Proficiency in Python (ML libraries, GenAI/LLM frameworks) and Java (enterprise application development, OOP).
• Practical experience developing with LLM frameworks such as LangChain, LangGraph, and vendor SDKs/APIs (OpenAI, Anthropic, etc.).
• Experience in using Al productivity tools such as Cursor, Windsurf, etc. is a plus or nice to have
• Experience with methods of training and fine-tuning large language models, such as distillation, supervised fine-tuning, and policy optimization is a plus or nice to have.
• Strong skills in prompt engineering and designing agentic reasoning pipelines.
• Solid understanding of ML evaluation techniques and experience in implementing model monitoring & metrics.
• Proven ability to debug and optimize inference pipelines for performance and cost efficiency.
• Strong problem solving skills with the ability to work in fast paced, agile development environments.
• Bonus: Contributions to open-source projects, blogs, or technical papers in LLM/GenA
