Senior LLM Inference Performance & Evaluation Engineer

Bitdeer (NASDAQ: BTDR); Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Bitdeer is seeking an experienced ML infrastructure engineer in Singapore to build benchmarks, manage model evaluation, and optimize performance for AI/cloud workloads. You will design gate criteria for model launches, maintain realistic workloads, and compare deployment options to optimize latency, cost, and reliability.

You will collaborate with runtime engineers and SRE to translate benchmark results into actionable SLOs and alerts, contributing to scalable and robust AI-enabled systems

Qualifications

• 5+ years in ML infrastructure, performance engineering, or backend testing.
• Experience with LLM serving metrics and model evaluation.
• Strong Python skills; Go is a plus.

Responsibilities

• Build benchmark pipelines for TTFT, inter-token latency, output throughput, request latency, concurrency curves, error rate, and GPU utilization.
• Create model launch gates covering OpenAI/Anthropic compatibility, streaming behavior, tool calling, reasoning output, multimodal behavior, and long-context cases.
• Maintain representative workloads using synthetic, replayed, and customer-like traffic patterns for both steady-state and burst scenarios.
• Compare model/runtime/provider options and publish clear recommendations for routing, fallback, pricing, and capacity decisions.
• Automate regression detection in CI/CD and staging so model, runtime, or configuration changes do not silently degrade quality, latency, or cost.
• Work with runtime engineers to identify bottlenecks and verify improvements; work with SRE to convert benchmark results into SLOs and alert thresholds.

How You Will Stand Out

• 5+ years in ML infrastructure, performance engineering, model evaluation, QA automation, or backend testing for production systems.
• Experience with LLM serving metrics such as TTFT, TPOT/ITL, request latency, token throughput, concurrency, and GPU utilization.
• Strong Python skills for benchmark/evaluation automation; Go experience is a plus for integrating with platform services.
• Familiarity with OpenAI/Anthropic APIs, vLLM/Dynamo/SGLang/Triton-style servers, and Kubernetes-based test environments.
• Able to design statistically meaningful tests and communicate tradeoffs between model quality, latency, reliability, cost, and customer experience.
• Experience building dashboards, reports, and release gates for engineering, product, and business stakeholders.

What You Will Experience Working With Us

• A culture that values authenticity and diversity of thoughts and backgrounds;
• An inclusive and respectable environment with open workspaces and exciting start-up spirit;
• Fast-growing company with the chance to network with industrial pioneers and enthusiasts;
• Ability to contribute directly and make an impact on the future of the digital asset industry;
