As a Machine Learning Engineer, you'd be joining a talented and friendly team which loves to delight its customers with quality and robust code. We care about user and developer experience and we work in an agile way to regularly ship code to production.

Team:

As Onfido tackles the problem of bringing identities online, this means taking on the challenges of bringing both Biometrics and ID Documents into the virtual world. The work you could come help us solve will involve: 

• Develop state-of-the-art machine learning-backed services for automated biometric verification, document classification and extraction, as well as fraud analysis;
• Build automated pipelines capable of minimising the time and effort of bringing support to new models and capabilities;
• Iterate over research projects to optimise them and deploy them to production;
• Continuously improve monitoring and tracing to provide a highly available service for our customers. 

We deeply value trust and ownership. Our engineers, product managers and designers work together closely to solve a challenging problem - identity in an online world - and build products that are polished and impactful.

What you will do:

• Work in a cross-functional team to design, build, test and ship fraud-catching products.
• Work closely with researchers to take research developed ML models to production.
• Use off-the-shelf machine learning solution to provide simple initial solutions for fraud detection.
• Design and implement efficient pre-processing steps around digital images or video files
• Extend existing ML pipeline to fit an increasing array of use cases
• Analyze algorithmic performances and identify common issues and potential improvements.
• Provide technical guidance, support and advice to other engineers at Onfido
