Our client is redefining fulfillment, warehousing, and logistics with robot-powered operations built for speed, scale, and accuracy. E-commerce brands depend on them to move inventory, process orders, and deliver same-day shipping across key metro markets. As they launch and scale their platform, you'll be joining a lean, high-velocity team-and influencing everything they build.

Role Overview

We're looking for a highly capable Founding Software Engineer with strong backend skills in Python/Django and a willingness to roll up their sleeves across the stack (including frontend when needed). You'll work closely with the CTO to design, build, and scale our core platform. This is a high-impact role where you'll shape engineering culture, deliver mission-critical systems, and help our business and operations move faster. Key Responsibilities

Architect, build, and maintain backend systems and APIs using Python and Django to support core logistics, fulfillment, order management, and operational workflows. Own infrastructure on AWS: design scalable, secure, and high-availability services that meet operational SLAs. Take ownership of both backend and frontend development as the sole engineer, implementing product features end-to-end and ensuring smooth, high-quality user experiences. Work directly with the CTO to define the technical roadmap, deliver features end-to-end, and iterate quickly based on business feedback. Build engineering practices and standards: code review frameworks, documentation, observability (logging, monitoring), CI/CD pipelines, and performance optimization. Be a key voice in shaping the engineering culture-from hiring decisions to team norms-setting the bar for quality, ownership, and collaboration. Support operations/data efforts: engage directly with stakeholders (product, operations, warehouse/logistics teams) to translate real-world fulfillment challenges into scalable software solutions. Required Skills & Experience

5+ years of software engineering experience, with strong backend expertise in Python and Django. Proven experience working in production environments on AWS with responsibility for architecture, scalability, and reliability. Comfortable working across the stack: though backend is primary, you can contribute effectively to the frontend when needed. Experience delivering end-to-end systems-from database to APIs to UI and deployment. Excellent problem-solving mindset: you thrive on solving complex infrastructure/data challenges and iterating quickly. Strong communication skills and ability to partner with business, product, and ops stakeholders. Self-starter and team player: able to work autonomously while collaborating closely with leadership. Commitment to onsite work 5 days per week in Concord, CA. Nice-to-Haves

Prior experience in logistics, fulfillment, warehousing, or 3PL systems. Familiarity with React, TypeScript, or modern frontend frameworks. Experience with event-driven architectures, microservices, or real-time data systems. Interest in robotics, AI, physical systems, or operational automation. Why You'll Love It Here

Be the first engineer helping to build the foundation of a high-growth startup. Direct impact: your work will power real fulfillment operations and robotic systems in production. Work side-by-side with the CTO and leadership team to shape both product and culture. Opportunity for growth: as the company scales, you'll be positioned to lead and grow the engineering organization.
