WHO WE ARE

Chess Solutions, LLC is a Virginia-based software development company that specializes in building digital vetting solutions. We work collaboratively with a number of clients to develop tools to facilitate client goals and mission objectives. In conjunction with our parent company, Presage Technologies, we integrate state-of-the-art, vision-based physiological analysis tools and digital media forensic tools into robust software platforms. Our goal is to provide our clients with the most accurate digital vetting and analysis tools possible in an easy-to-use, modern software experience.

WHAT YOU’LL DO

As a Senior Software Developer at Chess Solutions LLC, you will play a critical role in designing and building the applications and components that power our web and desktop applications. Your work will directly impact how our clients interact with mission-critical systems, supporting them in solving complex, real-world problems with innovative technology.

You will be responsible for designing and implementing scalable, high-performance applications and systems across multiple products. You have experience designing and building large microsystems architectures. You are fluent in Python, proficient in C++, and experienced with asynchronous task processing frameworks like Celery. You have a strong understanding of API design, data modeling, system architecture, and database management. You are a clear communicator and thoughtful planner. You know how to scope and estimate your time, work independently, and surface risks and dependencies early. You collaborate well with frontend engineers, product managers, systems engineers, and other stakeholders to translate customer needs into backend solutions. You are a diligent debugger and default to checking your part of the stack first when things go wrong – and expect the same from your teammates. You are exceptional at writing unit tests and value testing, automation, and reliability.

You write clear, useful documentation throughout the development lifecycle. You plan with intent, sharing architecture and implementation details early to invite feedback and improve outcomes. You understand the importance of different types of documentation, including internal developer docs, API references, compliance and security documentation, and integration guides for external teams.

This is a hybrid role , with an expectation of working in office or collaborating with customers/teammates in Northern Virginia (Leesburg, VA). Work will primarily be remote, but you will be available for in person meetings 4-5 times per quarter.
