What are the responsibilities and job description for the Mid-Level Software Engineer position at Tential Solutions?
Tential is hiring a Mid-Level Software Engineer for a national financial regulatory organization building a new platform that ingests trade data from multiple sources and surfaces investigative insights through correlation and analysis. It is a multi-year initiative with visibility across the organization, and there is room to grow into broader technical ownership.
You will work independently on complex efforts with general guidance, taking on problems of moderate to substantial scope that need sound technical judgment. If you are strong on the engineering fundamentals and want to go deeper on Big Data and applied GenAI, this is a good next step.
What You Will Do
The team hires for versatility and moves engineers across projects as work comes in, so there is genuine range here rather than one narrow lane. Interviews are onsite in Rockville and move quickly.
