NB: We are able to sponsor visas
Note on Salary: For exceptional candidates with strong product impact and relevant experience, we are open to offering compensation above the specified range.
Arva AI is revolutionising financial crime intelligence with our cutting-edge AI Agents. By automating manual human review tasks, we enhance operational efficiency and help financial institutions handle AML reviews, while cutting operational costs by 80%.
As an AI Research Engineer, you’ll play a pivotal role in building our in-house models—training, fine-tuning, and rigorously evaluating LLMs and agentic systems that power our AI compliance platform, from document fraud detection to web-scale due diligence. You’ll also develop the automation and infrastructure that continuously tests and improves performance (evals, data/label pipelines, training loops, and iterative fine-tuning/distillation).
About the Role
As an AI Researcher, you will:
- Build and iterate on in-house LLM and agentic capabilities, integrating them into product features with rigorous evaluation, benchmarking, and backtesting across real compliance workflows.
- Design continuous-improvement loops for our models, leveraging human-in-the-loop feedback to drive dataset curation, fine-tuning/distillation, and optimisation of model behaviour.
- Stay on the frontier and translate research into impact, exploring and applying new AI methods to improve model quality, explainability, latency, and reliability in production.
