Job Overview

The Linear Generator is a complex fusion of high-performance hardware and sophisticated control software. As our Staff engineer - Release management, you will be the conductor of the release symphony, ensuring that every code deployment—from firmware tweaks to high-level system optimizations—is delivered to our fleet with precision, safety, and transparency.

You aren't just pushing "update"; you are defining the bridge between our engineering lab and the physical power plants in the field.

Does your experience not meet all of our posted requirements? Studies have shown that some people are less likely to apply to positions unless they meet every listed requirement. At Mainspring, we are committed to building a diverse, inclusive, flexible, and collaborative environment, so if you want to help us transition the world to clean and affordable electricity, and don’t meet all posted requirements for a particular role, we’d still love to hear from you. Mainspring can sometimes be flexible enough to shift responsibilities for the right person, or otherwise identify open or upcoming roles that may better fit your professional background.

Responsibilities

Architect the Deployment Strategy: Define the "how" and "when" for software bundles, balancing the need for rapid innovation with the stability required for industrial power generation

Version Control & Bundling: Manage the integrity of software bundles, ensuring that dependencies between product variants, edge computing modules, and cloud telemetry are synchronized

Risk Mitigation: Establish "Go/No-Go" criteria for releases and design robust rollback procedures to protect hardware assets in the field

The "What & Why": Translate technical pull requests into meaningful Release Notes for both internal engineering teams and external clients/stakeholders

Impact Assessment: Clearly communicate how a specific software bundle changes machine performance, efficiency, or maintenance intervals

Inter-departmental Liaison: Act as the primary point of contact between Software Engineering, Product Management, and Field Operations

Command Center Guidance: Provide the "playbook" for the Field Operations & Assembly (FOA) team. You define the sequence; they execute the update

Technical Support: Serve as the escalation point during the update window, helping FOA troubleshoot deployment failures or unexpected telemetry readings

Feedback Loop: Aggregating data from field deployments to help Engineering improve the "deployability" and reliability of future builds

Qualifications

10+ years in Release Engineering, DevOps, or Technical Project Management (preferred: Hardware-in-the-Loop (HIL) or IoT environments)

Proficiency with CI/CD pipelines (GitHub Actions, GitLab CI, or Jenkins)

Proficiency with configuration management tools

Exceptional ability to explain a C++ logic change to a technician

Exceptional ability to explain a business value proposition to a VP

“Measure twice, cut once” mindset with strong attention to detail

What Success Looks Like

In your first six months, you will have moved our deployment process from a manual, "high-stress" event to a predictable, documented, and boring (in a good way!) routine. You will be the reason our field units are always running the best possible version of themselves
