Senior Software Engineer

Grow Your Career as a Software Developer in a Growing Company
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 .NET‑based 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 cloud‑hosted services and edge‑deployed components, while collaborating closely with a React‑based 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 data‑processing components

Improve and extend current systems with a focus on stability, clarity, and maintainability

Deploy and operate services in cloud and hybrid environments

Help shape how our existing backend runs in the cloud, without forcing premature vendor lock‑in

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 edge‑side 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-to-cloud contracts that align with our current backend model

Handle real‑world 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?
In addition to growth opportunities, as a Pro Mach 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 real‑world failure modes

Strongly Preferred

Experience with edge, on‑prem, or intermittently connected systems

Familiarity with CI/CD, monitoring, and operational tooling

Infrastructure‑as‑Code exposure (tool choice is less important than concepts)

Experience collaborating closely with frontend teams (React or similar)

Vacancy Status:  This position is for an existing job vacancy.
