[Remote] Lead Machine Learning Engineer, Inference & Performance

Note: The job is a remote job and is open to candidates in USA. Egen is a fast-growing and entrepreneurial company with a data-first mindset. As a Senior AI Engineer, you will be responsible for the full lifecycle of AI features, focusing on optimizing performance and collaborating with clients to create scalable AI architectures.

Responsibilities

• 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

Skills

• 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
• Mastery of Python and shell scripting; comfort reading and reasoning about lower-level (CUDA-adjacent) performance code is a strong plus
• Hands-on experience with vLLM, SGLash, or comparable high-performance serving stacks
• 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)
• Fluency with profiling tools to diagnose training and inference bottlenecks (compute-bound vs. memory-bound, kernel-level analysis)
• Strong Kubernetes (GKE) experience—deploying and autoscaling multiple models on shared GPU clusters on Google Cloud
• A strong software engineering foundation—you write clean, maintainable code, measure before optimizing, and understand the full SDLC
• 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
• Experience with Classic Machine Learning (neural nets, training, tuning) is a strong plus
• Knowledge of Data Engineering and SQL
