Vacant job

We're looking for an ML Research Engineer to join Klang AI, a fast-growing product company developing advanced AI solutions within speech and language technology.

Klang AI develops advanced AI solutions designed for organisations where security, privacy and trust are essential. In many environments, it's not enough for AI to be powerful—it also needs to be transparent, reliable and built with data protection and compliance at its core.

That's why Klang AI's products are trusted by organisations across the public sector, legal industry and research, helping transform meetings, interviews and client conversations into searchable transcripts, intelligent summaries and actionable insights. With more than 100,000 users, you'll have the opportunity to solve challenging technical problems while building AI that people can truly trust.

As an ML Research Engineer, you will:

• Train, fine-tune and improve machine learning and generative AI models
• Design and evaluate algorithms, experiments and benchmarking frameworks
• Work with datasets, data quality and model performance
• Build scalable systems that bring AI research into production
• Collaborate closely with the R&D team on technical decisions, research and product development

Who are we looking for?

We're looking for someone who enjoys solving difficult technical problems and is genuinely curious about advancing modern AI. You thrive in environments with a high degree of ownership, enjoy learning new things and like turning ideas into working systems.

We believe you:

• Have strong Python skills and solid software engineering fundamentals
• Have a strong understanding of machine learning and modern generative AI
• Enjoy driving open-ended technical challenges from idea to implementation
• Can clearly communicate technical reasoning and collaborate well with other engineers
• Use modern AI tools effectively to accelerate your work

Experience in one or more of the following areas is highly meritorious:

• Large-scale model training and fine-tuning
• Transformer architectures and modern LLMs
• Dataset design, evaluation and benchmarking
• Distributed training and AI infrastructure
• CUDA, Triton or GPU optimisation
• Speech recognition, text-to-speech or audio AI
• Research, scientific publications or meaningful open-source contributions

As a person, you're curious, pragmatic and collaborative. You enjoy experimenting, challenging assumptions and continuously improving both your own work and the technology around you.

What does Klang AI offer?

Klang AI is a product company transitioning from startup to scaleup, with a strong R&D culture and a clear focus on innovation. You'll work alongside highly experienced engineers and researchers in an environment where ideas matter more than hierarchy and where curiosity, experimentation and technical excellence are highly valued.

Working at Klang AI means tackling advanced challenges within machine learning, generative AI and speech technology. You'll have significant ownership, short decision-making paths and the opportunity to influence both the technology and the future direction of the company while building products used by more than 100,000 users.

This is a direct recruitment, where you'll be employed by Klang AI while Qlose manages the recruitment process.
