That way, Atlassians have more control over supporting their family, personal goals, and other priorities. We can hire people in any country where we have a legal entity.\nResponsibilities\nAs a ML System Engineer on the AI & ML Platform’s Inference team, you will design and optimize large-scale model serving systems end-to-end. You will have the chance to own everything from distributed infrastructure (global KV cache, continuous batching, load balancing, auto-scaling) to deep low-level optimizations (GPU kernels, quantization, speculative decoding).\nIn this role, you are expected to:\nArchitect and implement scalable distributed infrastructure for model serving (load balancing, auto-scaling, batch scheduling, global KV cache).\n\nOptimize latency and throughput of model inference under real production workloads.\n\nBuild reliable, high-concurrency serving systems that serve billions of requests reliably\n\nBenchmark, fine-tune, and accelerate inference engines.\n\nCreate robust CI/CD infrastructure for seamless model deployment and inference engine updates.\n\nPartner with senior ML engineers to fine-tune and deploy open-source LLMs\n\nQualifications\nOn your first day, we’ll expect you to have:\n3+ years of software engineering experience\n\nDeep low-level systems programming (C/C++ or Rust)\n\nExperience with large-scale, high-concurrent production serving.\n\nExperience with GPU inference engines (vLLM, SGLang, Triton, TensorRT-LLM, etc.).\n\nIt would be great, but not required if you have:\n1+ years of system performance optimization experience\n\nLow-level inference optimizations: GPU kernels\n\nAlgorithmic inference optimizations: quantization, speculative decoding, distillation\n\nExperience with testing, benchmarking, and reliability of inference services.\n\nExperience designing and implementing CI/CD infrastructure for inference.\n\nStrong background in system optimizations: batching, caching, load balancing, parallelism.\n\nBenefits & Perks\nAtlassian offers a wide range of perks and benefits designed to support you, your family and to help you engage with your local community. Our offerings include health and wellbeing resources, paid volunteer days, and so much more.
