Job description

Senior Software Engineer, Backend / Full Stack

Cytronic | Concord, CA | Hybrid

Cytronic is building the software and robot-powered operations behind modern fulfillment, warehousing, and logistics. We help e-commerce brands manage inventory, process orders, and deliver with greater speed and accuracy.

We are hiring our second full-time software engineer. You will join the CTO and our first engineer to build and scale the systems powering order management, warehouse operations, fulfillment, and customer-facing workflows.

This is a backend-leaning full-stack role with significant ownership. You will work primarily in Python and Django while contributing across the product, infrastructure, and frontend when needed to deliver complete solutions.

What You’ll Do
  • Design, build, and maintain backend systems and APIs using Python and Django.
  • Own features from problem definition through database design, implementation, deployment, and production monitoring.
  • Build software supporting fulfillment, inventory, order management, and warehouse operations.
  • Work directly with operations and business teams to turn real-world workflow challenges into scalable software.
  • Partner with the CTO and first engineer on architecture, technical priorities, and product delivery.
  • Improve the reliability, security, performance, and observability of production systems on AWS.
  • Contribute to frontend applications and internal tools when needed to deliver a strong end-to-end experience.
  • Help establish practical engineering standards for testing, code review, documentation, CI/CD, and incident response.
  • Shape Cytronic’s engineering culture and contribute to future technical hiring as the team grows.
What We’re Looking For
  • Five or more years of professional software-engineering experience, or equivalent evidence of senior-level ownership.
  • Strong production experience with Python and Django.
  • Experience designing APIs, relational data models, and maintainable backend systems.
  • Experience deploying and operating production services on AWS.
  • The ability to work across the stack and independently deliver complete features.
  • Sound judgment when balancing speed, scalability, reliability, and maintainability.
  • Comfort turning ambiguous business or operational needs into clear technical plans.
  • Strong communication skills with technical and nontechnical teammates.
  • Interest in working closely with warehouse operations and physical systems.
Nice to Have
  • Experience in logistics, fulfillment, warehousing, supply chain, or third-party logistics.
  • Experience with React, TypeScript, or another modern frontend framework.
  • Experience with event-driven systems, distributed systems, integrations, or real-time data.
  • Familiarity with warehouse-management, order-management, carrier, or e-commerce platforms.
  • Interest in robotics, AI, physical systems, or operational automation.
Why Join Cytronic
  • Join early and have meaningful influence over architecture, product direction, and engineering practices.
  • Own production systems that directly affect customers and physical operations.
  • Work closely with decision-makers, users, and warehouse teams.
  • Solve challenging problems at the intersection of software, logistics, automation, and robotics.
  • Help shape the engineering team as Cytronic grows.
Work Arrangement

This is a hybrid role based in the Concord, California area. Regular in-person collaboration is important because our software is closely connected to warehouse operations, robotics, and physical workflows. The specific weekly schedule will be discussed during the interview process.

Base salary: Competitive Base Salary plus equity and full benefits
