Job type: Full-time
Posting language: English
Posted: Nov 12, 2026

Original job description

Who are we?

Equinix is the world’s digital infrastructure company®, shortening the path to connectivity to enable the innovations that enrich our work, life and planet.

A place where tech thinkers and future builders turn bold ideas into breakthrough experiences, we welcome your unique perspective.Help us challenge assumptions, uncover bias, and remove barriers - because progress starts with fresh ideas. You’ll find belonging, purpose, and a team that welcomes you - because when you feel valued, you’re empowered to do your best work.

Job Summary

Researches, prototypes and proves new GenAI and agentic ideas that raise Equinix’s internal productivity and create capabilities for external products. Works in the AI Innovation and R&D pod, running experiments from hypothesis to working prototype, measuring each against quality, cost and business value, and handing validated ideas to product and platform teams as production-ready designs. Innovation areas include small language models (SLMs) and open-weight model customization, token economics, agent and workflow automation, and other emerging AI techniques.

Knowledge and Application

Applies deep working knowledge of modern AI techniques: LLM and SLM development, parameter-efficient tuning, distillation, quantization, retrieval, agent orchestration, and tool-use and function-calling models. Understands how model size, context length, caching and routing drive token cost and latency. Reads and applies current research, and benchmarks open-weight and commercial models on the same tasks. Applies established engineering and model-governance practices and proposes improvements.

Complexity and Problem Solving

Works on open-ended problems where the right approach is not yet known. Frames each idea as a testable hypothesis with success metrics, selects methods, datasets and evaluation criteria, and decides with evidence whether to scale, change or stop. Resolves tradeoffs among quality, cost, latency, security and operational complexity. Work is reviewed at design and milestone gates.

Collaboration and Interaction

Partners with Product, Platform, InfoSec, Legal, Finance and business teams to find high-value use cases. Explains results and tradeoffs to senior and non-technical stakeholders. Advises teams on which AI approach fits their problem. Accountable through the pod for delivery of innovation targets.

Responsibilities

Innovation and prototyping

Identify and test GenAI and agentic ideas for internal productivity and external product use cases
Build prototypes quickly, validate them with business teams against defined success metrics, and hand off production-ready designs and reference implementations
Track new models, techniques and tools; document which apply to Equinix and which do not

Small language models and model customization

Benchmark open-weight and commercial models on shared task datasets: quality, latency, cost, license terms
Fine-tune, distill and quantize models for defined tasks, including tool-use and agentic behavior, and show measured gains over the baseline
Feed results into the recommended-model catalogue owned by the Principal PM

Token economics and inference

Build cost models per agent and workflow: tokens, calls, caching, compute and cost per completed task
Test cost controls: model routing, context compression, caching, batching and budget limits
Optimize serving (e.g., vLLM, SGLang) with the platform team

Evaluation and rigor

Make experiments reproducible: versioned data, code, configs and results
Gate each prototype’s promotion on evaluation thresholds, using the Agent Intelligence evaluation platform
Turn failures and feedback into tuning data, regression tests or design changes

Responsible practice

Document each model or solution: intended use, data provenance, limitations and evaluation results
Apply license, data-boundary and security requirements with InfoSec and Legal

Qualifications

Required

5–8 years in ML or software engineering, including 3+ years in LLM or deep-learning development
Track record of taking AI ideas from prototype to production or to a documented decision to stop
Hands-on experience with at least one of: fine-tuning or parameter-efficient tuning (e.g., LoRA), distillation, quantization, agent or retrieval systems
Experience building evaluation harnesses and using results to make decisions
Ability to build cost and performance models for AI workloads
Proficiency in Python and PyTorch, and with Hugging Face tooling
Clear written and verbal communication with non-technical stakeholders

Nice to have

Experience with inference and serving (e.g., vLLM, SGLang), batching and GPU optimization
Preference optimization or reinforcement learning, and tool-use or function-calling fine-tuning
Experience with multi-agent systems, model routing and MLOps
Experience with open-weight model licensing, model governance or responsible-AI programs
Published research, patents or open-source contributions
BS or MS in computer science, machine learning or a quantitative field, or equivalent experience

What success looks like

Each quarter, a set of innovation ideas is tested, with a documented scale, change or stop decision for each
Each tested workflow has a measured cost per task and a documented model choice
Every promoted prototype has an evaluation record and documentation
