[job_card.job_description]

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.
