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.

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
