ZPI, the developer of the industry leading Zarpac Performance Index (ZPI) manufacturing performance improvement software, is seeking a Senior Backend Engineer to help evolve and operate our existing .NETbased backend platform as it expands into cloud and edge deployment models. This position is primarily based in-office, with the flexibility to work from home up to three days per week.

This role is intentionally focused on building on our current architecture, not replacing it. You will work primarily in a .NET backend environment, supporting cloudhosted services and edgedeployed components, while collaborating closely with a Reactbased web frontend.

 What You’ll Do

Backend Development (Primary Responsibility)

• Design, build, and maintain backend services and APIs within an existing .NET codebase
• Implement background services, schedulers, and dataprocessing components
• Own data ingestion, persistence, and servicetoservice communication
• Improve and extend current systems with a focus on stability, clarity, and maintainability

 Cloud Application Ownership

• Deploy and operate services in cloud and hybrid environments
• Help shape how our existing backend runs in the cloud, without forcing premature vendor lockin
• Own CI/CD pipelines, releases, monitoring, and production support
• Make architectural and operational decisions that the entire team can understand and maintain

 Edge & Distributed Systems

• Design and maintain edgeside services or agents, built using the same core backend technologies where possible
• Support:
• Data collection and buffering near devices
• Secure and reliable communication with cloud services
• Design edge ↔ cloud contracts that align with our current backend model
• Handle realworld constraints such as intermittent connectivity, versioning, and staged deployments
• This role does not involve hardware design, PLC programming, or field technician work.

What’s in it for you?

There's no monopoly on good ideas or limits to how far you can advance with our team. We offer an open, communicative environment that fosters individual initiative. We pride ourselves in being a company where people choose to build a career.

In addition to growth opportunities, as a ProMach employee, you receive more than just a paycheck. Total compensation includes your salary, comprehensive medical/dental programs, as well as life insurance, a generous paid time off program, and a retirement savings plan with a company match.

Please note that the pay ranges listed on external job boards, outside our posting details, do not accurately reflect our internal compensation ranges. 

Salary Range: $116,000K – $135,000K per year.

What We’re Looking For

Required Experience

• 7 to 10 years of experience building and maintaining backend services, preferably in .NET or similar ecosystems
• Experience deploying .NET services in cloud or hybrid environments
• Comfort working within an established codebase and improving it incrementally
• Experience operating production systems (debugging, reliability, performance)
• Solid understanding of APIs, data flow, and service boundaries
• Ability to reason about distributed systems and realworld failure modes

 Strongly Preferred

• Experience with edge, onprem, or intermittently connected systems
• Familiarity with CI/CD, monitoring, and operational tooling
• InfrastructureasCode exposure (tool choice is less important than concepts)
• Experience collaborating closely with frontend teams (React or similar)
