Senior Software Engineer - Factory Platform

About the position

You'll build our entire in-house ERP stack from scratch - manufacturing execution systems (MES), production planning engines, and durable workflow orchestration that runs our factory autonomously. The core challenge is automating complex manufacturing processes that span weeks while handling failures gracefully. You'll join our 8-person Factory Platform team within the 40-person Terrestrial Software organization. Direct collaboration with manufacturing engineers, test engineers, and operations staff.

Responsibilities

• Design workflow engines that coordinate hundreds of interdependent manufacturing steps.
• Build state machines that handle multi-week production cycles with automatic retry logic, human escalation, and rollback capabilities.
• Write planning algorithms that optimize schedules around material constraints, equipment availability, and test windows.
• Create fully-featured web applications used by technicians, engineers, and operators across the factory - everything from work order management to real-time process monitoring and intervention tools.

Requirements

• 7+ years shipping production software
• Expert-level React and modern frontend patterns
• Experience designing and maintaining service architectures that support complex business workflows
• Strong track record working directly with users to gather requirements, validate assumptions, and iterate on solutions
• Experience implementing reliable workflows at scale - handling failure scenarios, state recovery, and distributed coordination
• CS/Engineering degree or equivalent depth

Nice-to-haves

• Systems programming background
• Workflow orchestration experience (Temporal, Airflow, etc.)
• Manufacturing automation domain knowledge
