About the opportunity: 
 
As a Senior AI Engineer, you will be at the forefront of our Generative AI initiatives. We treat AI as a software engineering discipline. You will be responsible for the full lifecycle of our AI features—specifically document intelligence and RAG pipelines—taking them from initial prototype to robust, scalable production services. You will solve for real-world constraints like latency, error handling, and cost optimization.
 
You’ll collaborate with a diverse range of clients to translate business needs into high-performance AI architectures. This role requires a blend of deep technical expertise in LLMs and a disciplined Software Engineering approach to ensure our solutions are robust, ethical, and scalable.

What You Will Do:
Optimize Inference: Build and tune production LLM serving with vLLM and SGLang—maximizing throughput and minimizing latency through batching, paged attention, quantization, and KV-cache strategies Profile & Accelerate Training: Instrument and profile training runs to find bottlenecks, then resolve them with the right attention implementations (e.g. FlashAttention) tuned to the underlying hardware (H200, GB200) Engineer for the Hardware: Apply a working understanding of GPU architecture and attention internals to choose the right approach per accelerator, rather than relying on defaults Serve at Scale: Deploy and operate multiple models within shared GPU clusters on GKE, with autoscaling, efficient bin-packing, and graceful handling of mixed workloads Drive Efficiency: Own GPU utilization as a first-class metric—measure it, improve throughput-per-dollar, and continuously raise the ceiling on what our fleet can deliver Collaborate & Consult: Work directly with clients to understand performance, latency, and cost requirements, and translate them into pragmatic serving and training architectures

Your Technical Toolkit:
Core Languages: Mastery of Python and shell scripting; comfort reading and reasoning about lower-level (CUDA-adjacent) performance code is a strong plus Inference Frameworks: Hands-on experience with vLLM, SGLash, or comparable high-performance serving stacks GPU & Model Internals: Solid grasp of GPU architecture, the fundamentals of LLM inference, and the attention mechanism—including where the bottlenecks live and how FlashAttention and similar techniques address them across hardware generations (H200, GB200) Profiling: Fluency with profiling tools to diagnose training and inference bottlenecks (compute-bound vs. memory-bound, kernel-level analysis) Infrastructure: Strong Kubernetes (GKE) experience—deploying and autoscaling multiple models on shared GPU clusters on Google Cloud Mindset: A strong software engineering foundation—you write clean, maintainable code, measure before optimizing, and understand the full SDLC

Basic Qualifications:
Bachelor's or Master's degree in Computer Science, Engineering, or a related technical field 5+ years of experience in ML/AI engineering, with a meaningful portion focused on performance, infrastructure, or systems Proven track record of deploying and optimizing models in a production environment Demonstrated experience profiling and improving GPU utilization for training and/or inference Experience with Classic Machine Learning (neural nets, training, tuning) is a strong plus Knowledge of Data Engineering and SQL

Personal Attributes:
Ownership: You take pride in your work and see optimizations through from profile to production Curiosity: Hardware and serving frameworks change fast; you are a lifelong learner who stays ahead of the curve Rigor: You measure before you optimize and let data, not intuition, guide where you spend effort Consultative Spirit: You enjoy interacting with clients and can translate technical complexity into business value Ethics: You prioritize responsible AI development and data privacy

Compensation & Benefits:
 
This role is eligible for our competitive salary and comprehensive benefits package to support your well-being:
- Comprehensive Health Insurance
- Paid Leave (Vacation/PTO)
- Paid Holidays
- Sick Leave
- Parental Leave 
- Bereavement Leave
- 401 (k) Employer Match
- Employee Referral Bonuses
