You must be authorized to work in the United States without employer sponsorship now or in the future. We will not sponsor employment visas. Candidates who will require future sponsorship, including candidates on CPT/OPT/STEMOPT who will require future sponsorship, are not eligible to apply.

At Liberty, you'll thrive in a hybrid setting that fosters in-person collaboration, innovation and growth. This approach optimizes both remote and in-person interactions, enabling you to connect and ideate with your team and deepen valuable relationships across the company, while still enjoying the flexibility of remote work for focused tasks and projects. This position follows a hybrid work model (2 days onsite) and is open to candidates located in Portsmouth, NH; Boston, MA; Plano, TX; Indianapolis, IN; Columbus, OH and Seattle, WA.

Want to work at the leading edge of emerging technology and rapidly expand your engineering skill set? Join Best Coding Squad (BCS), where we develop full-stack solutions with a strong focus on data and insights. Our applications feature cutting-edge GenAI capabilities, agentic workflows, and embedded predictive models (pricing, risk selection, desirability, and more) that streamline manual processes and improve decision-making for our users.

As part of BCS, you'll join a cross-functional team of Data Scientists, Data Engineers, and Software Engineers, working together to design data-centric solutions for our business stakeholders. Together, we build, test, and maintain the technical architecture behind our applications, data pipelines, databases, APIs, and predictive model workflows.

The ideal candidate is a strong communicator with excellent self-motivation and a proactive approach to learning. A growth mindset is essential as we're constantly exploring new and emerging technologies at the frontier of AI.
