Senior Staff Software Engineer (MES & Distribution Systems)

The role

You will design and build a next-generation Manufacturing Execution System (MES) to power high-volume production of silicon photonics devices. This involves designing distributed backend systems, microservices, and data pipelines to integrate shopfloor control with ERP and external platforms.

What you will do

• Design and build distributed backend systems supporting MES and shopfloor control
• Define system architecture, APIs, and data models
• Develop microservices and integrations connecting internal systems with ERP, vendors, and manufacturing partners
• Analyze existing MES and enterprise solutions to inform system design
• Translate evolving requirements into technical solutions
• Lead prototyping, proof-of-concept development, and iterative system refinement
• Design and implement data pipelines and workflows across multiple systems
• Enable real-time data movement, transformation, and event-driven automation
• Build integrations that connect manufacturing systems, external partners, and internal tools
• Conduct code reviews and enforce strong development standards

Required qualifications

• 5+ years of experience building backend or distributed systems
• Strong programming experience in languages such as C#, Java, or Go
• Solid understanding of distributed systems, microservices, and API design
• Strong database design skills (relational models, normalization, performance)
• Experience with concurrency, parallelism, and scalable system design
• Proficiency with Git, branching strategies, and modern development workflows
• Strong analytical mindset with the ability to operate in evolving, ambiguous environments
• Excellent communication skills and ability to work cross-functionally

Nice to have

• Experience with MES or manufacturing systems
• Familiarity with manufacturing concepts: BOM, work orders, MRP, production planning
• Shopfloor operations, quality, traceability, inventory
• Experience integrating with industrial equipment or IoT systems
• Exposure to frontend technologies (React, Vue)

Benefits

• Competitive compensation
• Meaningful equity
• Opportunity to build a greenfield, mission-critical system from the ground up
• Direct impact on cutting-edge AI and photonics infrastructure
• Collaborative, high-caliber engineering team
• Fast-paced, high-growth environment with significant ownership
