About The Role

: We are seeking a talented and motivated AI Engineer II who is best in class, with a high IQ and a high EQ. This role presents an exciting opportunity to thrive in a dynamic, fast-paced environment within a rapidly growing team, with strong prospects for continued growth and increased ownership. As an AI Engineer II on the Applied AI team, you will take on end-to-end ownership of complex platforms and systems that power Sezzle's AI-driven capabilities.

Your work will span initiatives such as building AI-powered platforms from scratch, developing intelligent automation and orchestration systems, and embedding proprietary AI solutions directly into customer-facing products, internal tools, and operational workflows. You will operate in highly ambiguous problem spaces, working closely with product, engineering, and operations teams to identify opportunities where AI can drive meaningful impact — whether that's enhancing the customer experience, improving decision-making, or automating complex workflows. This role is ideal for engineers ready to move beyond scoped execution and into leading solutions: shaping architecture, driving implementation, and ensuring that what is built is reliable, scalable, and genuinely useful for both external users and internal teams.

What You'Ll Do

: Lead the design, development, and ownership of AI-powered internal platforms and systems, including initiatives built from the ground up with a focus on Marketing. Own end-to-end delivery of complex projects, from problem discovery and system design through production rollout and iteration. Design and implement AI-driven features, intelligent automation, and orchestration systems that enhance customer experiences and compound productivity across teams.

Embed AI capabilities into customer-facing products, internal tools, and operational workflows, ensuring solutions integrate naturally and deliver measurable value. Build full-stack systems spanning backend services, APIs, data layers, and frontend interfaces. Translate ambiguous business and operational problems into scalable, maintainable, AI-enabled technical solutions.

Apply strong systems thinking to ensure reliability, performance, security, permissions, and auditability across platforms. Collaborate closely with engineers, teams, and stakeholders across the company to identify high-impact opportunities and drive adoption. Participate in production support and incident response for owned systems, helping define and uphold reliability and operational best practices.

Mentor AI team members through code reviews, design feedback, and hands-on guidance, raising the overall quality bar of the team. What We Look for: 3–5 years of professional experience in software engineering, AI engineering , platform engineering, or related roles. Hands-on experience designing, building, and shipping AI-powered systems into production environments.

Strong proficiency in Python, SQL, and frontend frameworks such as React.
