Senior Software Engineer - Python/AI

As a Senior Software Engineer you will be responsible for implementing and maintaining mission critical applications and services related to our trading and risk management platforms. You will also lead initiatives at the intersection of data infrastructure and AI integration. This role involves building scalable data pipelines, staging data for AI/ML workflows, integrating AI into production applications, and ensuring the reliability and relevance of LLM outputs. You’ll collaborate with teams across the firm—including product, data science, and engineering—to define and implement intelligent, data-driven features that power our next-generation products.

Successful candidates will embrace the cultural principles at Voloridge:

Drive creativity and find pleasure in your work: You love coding and technology. It is as much a hobby as it is work. Whether it is following blogs and podcasts, to downloading and trying out new projects from Github or elsewhere you have ideas you want to explore. Learning new things and bringing new ideas and solutions to the challenges we face is a key driver of innovation and excitement.

Seek continual improvement and roll-up-your sleeves: Be willing to learn whatever technologies, tools, or patterns necessary to solve a problem. These are critical systems, and you cannot avoid a problem because "someone else 'owns' the code" - learn the code, learn the domain, solve the problem.

Embrace truth and openness and practice humility and honor: We are a collection of top-performers with strong opinions but respect for the ideas of others is a must for finding the right solution. Everyone makes mistakes at times, so we don’t judge others. What is important is uncovering errors quickly, getting fixes in place, and understanding what can be improved for next time.
