Senior AI/ML Software Engineer (LLM Focus)

Role Overview

We’re looking for a talented Senior level AI/ML Software Engineer with strong LLM expertise to join a high-impact team building intelligent, cutting edge production-ready systems. This role has a clear emphasis on Large Language Models — designing, developing, and deploying advanced LLM-powered solutions that deliver real business value.

You’ll work at the intersection of software engineering and Large Language Models, taking LLMs from experimentation through to robust, scalable, and secure production systems integrated into both desktop and web applications.

What you’ll do:

* Architect, fine-tune, and deploy Large Language Model solutions and pipelines

* Integrate LLMs into existing C++ and web applications

* Design and build production-grade LLM systems with a strong focus on performance, reliability, security, and cost-efficiency

* Work extensively with unstructured data using RAG (Retrieval-Augmented Generation), alongside structured (SQL) and time-series/streaming data

* Develop robust APIs and integration layers for LLM capabilities

* Collaborate with engineering, data, and product teams to deliver end-to-end LLM-powered features

* Champion best practices in LLM engineering, MLOps, evaluation, monitoring, and observability

About You:

* You’re a strong software engineer who is passionate about Large Language Models

* You have hands-on experience designing, optimising, deploying, and maintaining LLM systems in production environments

* Proficient in Python, with solid experience in C++ or C# (experience integrating LLMs into C++ applications is highly valued)

* You write clean, well-tested, production-grade code and care about reliability and scalability

* Excellent communicator who can explain complex LLM concepts clearly to technical and non-technical stakeholders

Experience & Qualifications:

* A PhD or Masters in Computer Science, Engineering, or a related field

* Strong background as a Software Engineer with significant LLM experience

* Track record of successfully delivering complex LLM-powered features or systems

* Experience with secure handling of sensitive data and compliance standards is a plus

What’s in it for you:

* Highly competitive salary

* Excellent benefits package including generous annual leave, private health & dental insurance, pension (matched up to 10%), and more

* Real ownership and impact on cutting-edge LLM projects

* Training and development opportunities

* Visa sponsorship and relocation support (where applicable)

If you’re excited by Large Language Models and want to build production systems that matter, we’d love to hear from you!
