Software Engineer (Senior)

About the role

Own major product areas end to end, from customer problem and technical design through implementation, launch, and iteration
Design durable APIs, data models, workflows, and system boundaries for products operating on high-stakes financial and regulatory data
Build across the stack, including backend systems, data pipelines, AI-powered workflows, and polished customer-facing interfaces
Turn complex regulations and messy trade data into products that feel simple and reliable
Work directly with enterprise customers to understand their operations, identify the real problem, and ship solutions quickly
Establish technical direction while making pragmatic decisions about speed, quality, and long-term maintainability
Raise the engineering bar through thoughtful design, strong execution, clear communication, and mentorship
Help shape our engineering culture, architecture, hiring, and technical roadmap
Build with large language models where they create real leverage and use deterministic systems where accuracy demands them

Responsibilities

• Own and deliver an end-to-end project alongside a founder, likely involving AI-assisted workflows, complex data, or regulatory logic
• Take responsibility for a major product or technical area, including its architecture, execution plan, and production quality
• Work directly with enterprise customers, turn ambiguous operational problems into product decisions, and lead delivery from discovery through adoption
• Build systems that reconcile tens of millions of dollars in annual trade volume, interpret thousands of pages of federal regulations, transform customs documents into structured data, or help an AI agent audit every line of an import entry before it reaches the government
