Senior Inference Engineer
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Inference Engineer based in United Kingdom.
This is an opportunity to become the first dedicated engineer responsible for building and owning an inference platform from the ground up.
You’ll work closely with the CTO to turn large language models into reliable, production-grade query-to-response systems running at scale.
The role combines hands-on infrastructure engineering with performance optimization across GPU-based environments.
You’ll work with modern serving technologies such as vLLM, SGLang, and TensorRT-LLM while solving real-world challenges around latency, cost, and throughput.
As the platform matures, you’ll take increasing ownership of its technical direction and collaborate with Product on the future inference roadmap.
You’ll join a remote-first, open-source-oriented startup where engineering ownership, speed, and measurable customer impact are highly valued.
This role is ideal for a senior engineer who wants significant autonomy and the opportunity to define how production inference infrastructure is built and scaled.
Accountabilities
- Build and deploy production-grade LLM inference systems across one or multiple GPU machines, owning the complete pipeline from customer query to served response.
- Design, implement, and operate model-serving infrastructure using technologies such as vLLM, SGLang, and TensorRT-LLM.
- Optimize inference workloads for scale, balancing latency, throughput, reliability, and infrastructure costs.
- Apply techniques such as quantization, batching, caching, and intelligent request routing to improve inference performance.
- Develop robust production infrastructure using Python or Golang, with an emphasis on maintainable, scalable engineering rather than configuration-only work.
- Establish the initial inference platform in close collaboration with the CTO and take ownership of its evolution as the organization scales.
- Define and execute the technical roadmap for inference infrastructure, identifying opportunities to improve performance, reliability, and developer or customer experience.
- Partner with Product to translate evolving customer and market requirements into practical inference-platform capabilities.
- Evaluate emerging inference technologies and approaches and determine where they can create meaningful improvements.
- Collaborate with engineering stakeholders to establish reliable operational practices for production GPU infrastructure.

Requirements:
- Significant professional experience building and operating production software or infrastructure systems, with strong hands-on engineering capabilities.
- Demonstrated experience deploying and serving large language models in production, ideally using vLLM, SGLang, TensorRT-LLM, or comparable inference frameworks.
- Practical expertise optimizing inference workloads through quantization, batching, caching, routing, or similar techniques.
- Strong programming skills in Python or Golang, with a track record of writing and maintaining production-quality code.
- Strong understanding of production inference architectures, including the journey from user request through model execution to a reliable served response.
- Excellent problem-solving skills and the ability to independently investigate complex performance, scalability, and reliability challenges.
- Strong communication skills, with the ability to explain sophisticated technical concepts clearly to engineers, product stakeholders, and other audiences.
- Comfortable taking significant ownership, working with ambiguity, and making pragmatic technical decisions in a fast-moving environment.
- Familiarity with Docker and Kubernetes is a plus.
- Hands-on experience with generative AI technologies such as PyTorch or Transformers is advantageous.
- Knowledge of the GPU software stack, including CUDA, NCCL, drivers, and related libraries, is beneficial.
- Understanding of model architectures and fine-tuning techniques is a plus.
- Experience with NVIDIA Dynamo is an additional advantage.
