Opportunity

As a Software Engineer at Quantexa, you’ll play a key role in shaping one of the most critical components of our Decision Intelligence platform: Decision Systems.

The Decision Systems team is responsible for turning complex, interconnected data into actionable insights — helping global organizations detect patterns, uncover risks, and make smarter decisions. You’ll work across the software stack, from enhancing our scoring capabilities to uncover financial crime, to building tools that make detection logic easier and more powerful for our users. Your work will directly influence how clients identify suspicious activity and protect their businesses.

This isn’t just about coding, stakeholder management will be a growing focus of this role. You’ll have the autonomy to take features from concept to release, collaborating closely with product teams and delivery experts to design solutions that make a real impact. You’ll be part of a talented, supportive team that values innovation, knowledge sharing, and continuous improvement.

The role is focused on software development using the latest in agentic AI tooling. Typical tasks in the team are:

• Building new tooling to allow users to configure detection logic more easily and effectively

• Enhancing the platform so that existing Scores can be applied across a wider range of scenarios

• Improving the performance of the system so even the largest datasets can be analysed efficiently

There are 3 different sub-teams within Decision Systems, each focusing on different areas across the scoring capability within Quantexa. Specifics of the remit and differences between these teams can be shared upon request.

We have a great team culture, with regular socials and a strong presence in Quantexa’s London office, whilst maintaining a flexible working policy allowing for regular home working. Come and be a part of the next stage of the growth of our team and Quantexa as a whole!
