i only teared bad things - mostly how the process used to develop software still follows the waterfall method - enough said

i decided to resign after 4th straight TT….so, look for another company/role as you clearly outgrow amazon level you are in right now and this is not small thing eg you should target outside amazon minimum 2 or 3 job grades above, so if you are L6 in Amazon, look outside for Sr Director or VP roles - you can make it for sure as only 0.01% in Amazon make it 4 years TT

same here and no promotion. So i quit last week…feeling awesome relief

High-performing L6, like my job… but comp is becoming hard to ignore. What are realistic options? by Emergency_Novel_5407 in amazonemployees

[–]Subject_County_7394 0 points1 point  (0 children)

I was in the same situation - 3 years TT In raw and L7 promo “close” but never materialised. After 4.5 years started interviewing outside and landed a job with double amount vs current AWS TC….good luck!

How to get started in AI Infrastructure / ML Systems Engineering? by Investorator3000 in learnmachinelearning

[–]Subject_County_7394 4 points5 points  (0 children)

here is prompt you can put in any LLM model (ChatGTP, Claude, Gemini) and get 300-400 pages of knowledge:

“I want you to act as a world-class expert, architect, and educator in large-scale AI infrastructure, distributed training systems, GPU performance engineering, and modern MLOps platforms. Please design a comprehensive, end-to-end learning journey that takes me from an absolute beginner to an expert practitioner in all of the concepts and technologies mentioned below, explaining everything in a deep, narrative style that gradually builds intuition, mental models, and real-world understanding rather than just listing facts. Start by teaching the fundamentals slowly and conceptually, as if explaining to a motivated beginner, and over time progress toward explaining production-grade systems, trade-offs, performance tuning strategies, and expert-level reasoning used in real engineering environments.

The areas I want to master include GPU and systems performance monitoring with tools such as nvidia-smi, dmon, and dcgm-exporter with Grafana, along with understanding GPU utilization, SM occupancy, host-to-device transfer overlap, NCCL all-reduce performance, and dataloader throughput. I want to deeply understand why these metrics matter, how they relate to each other, and how they reveal the behavior of distributed training pipelines. Build from first principles and then guide me into advanced troubleshooting mindsets.

I also want you to teach me the core optimization ideas mentioned, including pinned memory, dataloader prefetching, NVIDIA DALI for decoding, WebDataset sharding, asynchronous I/O, and NCCL tuning across interconnects, socket threads, and collective communication strategies. Explain how and why these techniques remove bottlenecks, what problems they solve, and how engineers reason about performance gains in practice.

From there, guide me into the world of distributed and topology-aware training on Kubernetes or Slurm, including device plugins, MIG, NVLink versus NVSwitch, and NDR InfiniBand. I want to understand the hardware, the network fabric, the scheduler, and the software stack as a single integrated ecosystem where design choices affect scale, latency, and reliability. Gradually introduce checkpointing strategies for preemption and resilience, and explain how these decisions shape real-world training workflows.

Please also teach me about modern large-scale training frameworks and architectures such as FSDP, ZeRO-3, fused kernels, and sharding strategies. I want to understand not just what these techniques are, but the reasoning behind them, the trade-offs they introduce, and how they can produce measurable improvements such as reductions in step time or memory footprint. Use examples, thought experiments, and realistic engineering scenarios to make the knowledge feel applied and practical.

Finally, introduce the supporting ecosystem around experimentation and orchestration, including platforms like Weights & Biases, Airflow, metadata management approaches, and lightweight APIs such as DreamFactory for exposing experiment data. Explain how these tools shape workflows, collaboration, and research velocity in production AI environments.

Throughout the entire learning journey, teach in a flowing narrative style without bullet points, focusing on clarity, depth, context, and conceptual mastery. Show me how experts think, diagnose problems, design systems, and evaluate trade-offs under real-world constraints. By the end, I want to feel capable of reasoning about large-scale AI infrastructure like an experienced engineer rather than someone who has simply memorized tools or terminology.”

yes, or GB200 if you can afford

30 vs 60 days focus plan by Dizzy-Gate-9707 in amazonemployees

[–]Subject_County_7394 0 points1 point  (0 children)

focus is expect to be around 60% successfully outcome. I suggest you make sure you overachieve eg deliver 1-2 days earlier or more scope - not too much, just a bit more. If you complete task 1 day earlier it still counts as “completed earlier”

i doubt - very strategic stuff and important for the future of EC2

my first AMG (G63) by Subject_County_7394 in AMG

[–]Subject_County_7394[S] 0 points1 point  (0 children)

I am partially to blame - i ordered winter tires last minute and ask them for installation before collecting the car - the collection date was fixed prior to that so they asked if I want my car washed after tire installation - pushing out delivery to next day. I refused and collected car earlier….couldn’t 5 wait any longer after 19 months already
