# Founding Speech Model Performance Engineer

- **Company:** Slng Ltd
- **Location:** Barcelona, Spain (Remote available)
- **Contract:** Permanent contract
- **Skills:** Microsoft Word, Nvidia CUDA, Pytorch, ONNX (Open Neural Network Exchange) Format
- **Published:** August 4, 2026
- **Apply:** https://www.jobleads.com/es/job/e5eb448d696c91016b0a07cbfa27d3069

## About the Role

* Strong background in ASR/TTS.
 * PyTorch/ONNX experience.
 * Familiar with GPU profiling and optimisation.
 * Fluency in English.

## Description

As Speech Model Performance Engineer, you'll work closely with Ismael and the founding tech team to shape the technical foundation of SLNG. From TTS voices to multilingual ASR, you'll benchmark, optimise, and productionize speech inference at scale., You'll Make Speech Models Fast.

Example Initiatives

 * Quantise neural TTS and STT models to run with minimal latency on heterogeneous GPU hardware.
 * Benchmark ASR models across dialectal variations, measuring Word Error Rate (WER) and latency trade-offs.
 * Implement continuous batching and KV-cache reuse for streaming inference.
 * Profile GPU utilisation with CUDA kernels to identify bottlenecks in large-scale inference.
