About the role

Our partner is looking for a Senior Engineer, Core Products based in the United States. As a Senior Engineer, Core Products, you will own product features from strategy and design through launch and continuous optimization. You will work across fintech, embedded finance, and real-time payroll systems serving millions of transactions with demanding performance requirements. The role combines full-stack engineering, scalable architecture, AI-native development, and strong product thinking. You will partner closely with product, design, and data teams to shape technical direction and challenge assumptions before implementation. Your work will influence both customer-facing experiences and the systems, data pipelines, and analytics that support them. You will also help introduce modern AI models, autonomous agents, and agentic workflows into engineering practices and product architecture. This is an opportunity to take significant ownership, solve complex technical problems, and directly contribute to products designed to improve financial access for workers.

Responsibilities

• Own features and initiatives end-to-end, partnering with product, design, and data teams to define technical strategy, evaluate trade-offs, and align implementation with customer and business outcomes.

• Develop and deploy AI-enabled product capabilities, including features powered by modern AI models, autonomous agents, and agentic workflows.
• Drive the adoption of AI-native engineering practices and modern development tools to improve engineering velocity, software quality, and user experiences.
• Take responsibility for products after launch by defining and instrumenting key metrics, monitoring performance dashboards, investigating gaps, and iterating based on user behavior and business results.
• Contribute across the full technology stack, taking ownership of complete products or features from frontend experiences through backend services, databases, infrastructure, and supporting integrations.
• Help shape architecture and product decisions while maintaining a strong focus on performance, security, scalability, operational reliability, and measurable customer impact.
• Collaborate closely in a fast-paced, highly communicative environment where clarity and precision in both written and verbal communication are highly valued.
• Participate in occasional company onsite meetings and project-planning sessions, typically around 2–4 trips per year, depending on business needs.
