Senior Software Engineer, Full-Stack & AI Systems

Role Overview 

We are seeking a Senior Software Engineer to architect and scale our platform-level agentic AI systems. This role combines full-stack engineering excellence with deep expertise in LLM-powered experiences. You’ll design, implement, and optimize core components across frontend, backend, and model integrations, while driving engineering direction in close collaboration with our co-founders. Your work will directly shape the reliability, speed, and cohesion of company’s multi-agent ecosystem.

Key Responsibilities 

• Architect and implement cross-agent systems that power core platform experiences.
• Build and scale full-stack product components using TypeScript/React and Python services.
• Integrate LLMs into production workflows with strong contracts, observability, and test coverage.
• Develop shared UI components and typed SDKs to unify cross-agent experiences.
• Lead engineering direction, collaborating with founders and cross-functional stakeholders.

Requirements

• Senior-level full-stack experience in React, TypeScript, and Python.
• Proven ability to design, ship, and scale LLM-powered applications.
• Expertise in API design, streaming, and CI/CD pipelines.
• Strong cloud infrastructure background (AWS, GCP, or Azure).
• Track record of building reliable systems with measurable performance and error budgets.

Nice-to-Have 

• Experience with WebRTC or audio-aware UI design.
• Hands-on work with agentic AI frameworks.
• History of creating design tokens, SDKs, or cross-agent platforms.

First-Month Focus

• Audit current cross-agent flows for UI/UX cohesion.
• Implement shared components and typed contracts for reliability.

• Establish instrumentation for frontend performance and model round-trip tracing.

   

Success OKRs (90 Days)

• Deliver end-to-end tested, production-grade agentic workflows with <5% error rates.
• Launch cross-agent design system and SDK used by at least 2 internal teams.
• Establish weekly “deploy and measure” cadence with performance metrics and error budgets.
   

Culture Fit

• Persistent, driven problem solver
• Willing to push back on leadership to defend quality/timelines
• Thrives in high-ambiguity, fast-paced startup environments

We're revolutionizing international commerce by enabling fast, seamless global shipping for direct-to-consumer brands. We've built a sophisticated software platform that orchestrates complex supply chains across warehouses, airlines, customs systems, and carriers, turning the complexity of cross-border logistics into a seamless customer experience for international shoppers. Our technology connects brands to new markets and helps customers access products they love regardless of geography. If you're passionate about solving complex technical challenges and building the infrastructure that powers global commerce, join our team of builders and innovators reshaping supply chains and connecting people. In recent months, we have secured critical new partnerships and traction and are looking for new teammates who will help us develop thoughtful systems that allow us to handle this new scale.

What it's like to work here

We’re a small, focused team taking on interesting operational and technical problems. Our team members have a high degree of autonomy, and are deeply involved in product and technical decision making. Working with us, you’ll get to investigate complicated logistics problems to develop opinionated, first-principles solutions.

In a typical day, you might

• Collaborate on product direction and identify opportunities to improve the customer experience
• Design and build features end to end, from API to UI, alongside collaborative teammates
• Troubleshoot live issues with stakeholders such as warehouse or fulfillment partners
• Work with a developer-friendly, modern stack
• Contribute to a culture that values thoughtful discussion, quick iteration, and high standards

What we’re looking for

We're looking for a seasoned full-stack engineer who enjoys owning new features, working directly with stakeholders, and is motivated to iterate until a problem is solved. Our ideal teammate is reactive when a critical issue arises, but is also willing to take the time to work through a fully realized solution over a longer time scale.

What you offer

• 6+ years of experience building scalable web applications with real-world usage
• A strong product mindset, with an eye for intuitive UI/UX and practical design
• The ability to lead technical projects and influence architecture across the codebase
• A track record of solving complex, open-ended problems independently
• Excellent communication skills and a collaborative, low-ego attitude
• Deep expertise with front-end development (HTML, CSS, JavaScript, React, browser APIs)
• Proficiency in JavaScript, TypeScript, and Node.js. Serverless experience is a plus
• Significant experience designing and integrating APIs

• A solid understanding of event-driven architecture and scalable systems design
