Architects software test and automation infrastructure for distributed energy systems. Develops hardware test beds, reusable automation frameworks, CI/CD pipelines, test plans, traceability matrices, and risk-based coverage strategies. Leads system validation, integration testing, failure analysis, debugging, and root-cause investigations across real-time embedded software, predictive controls, and multi-fuel dynamics. Collaborates with engineering teams to diagnose anomalies and validate new technologies.

Manage financial planning, budgeting, forecasting, reporting, and profitability analysis for the Services business. Partner with Operations, Field Service, Supply Chain, Accounting, and senior leadership to model labor, spare parts, service contracts, warranty, capital investments, and operating metrics. Translate fleet and field-service performance into financial insights, identify margin improvements, support pricing and contract analysis, and develop dashboards and reporting tools.

Diagnose and resolve field issues in automated power-generation systems, determine mechanical, electrical, and software root causes, debug C++ control algorithms, implement and test fixes, analyze data with Python, tune control gains, calibrate systems, and improve reliability, manufacturing testing, and sustaining engineering processes.

Supports supply chain cost analysis, BOM cost roll-ups, should-cost modeling, cost-down tracking, capacity planning, and reporting. Collaborates with procurement, engineering, commodity management, finance, and suppliers to validate cost and capacity data, identify savings opportunities, maintain dashboards, and track project progress. The role is designed for someone with 0–3 years of experience to develop cost engineering expertise in a hardware environment.

Supports corporate governance, board processes, entity management, securities and financing transactions, equity administration, legal operations, contract records, diligence, and outside counsel coordination. Maintains corporate books, cap tables, transaction documentation, legal systems, and compliance deadlines while partnering with Finance, People, executives, attorneys, and external advisors. The role requires strong organization, discretion, communication, project management, and independent ownership in a growing company.

Monitor system alerts during assigned shifts, follow troubleshooting flowcharts, restart hardware, escalate unresolved issues, and maintain detailed action logs. The role provides flexible afternoon, weekend, and absence coverage while supporting operations for electromechanical power systems. Success requires technical aptitude, attention to detail, independent judgment, strong communication, and the ability to prioritize issues in a fast-paced environment.

Lead development of piston and ring sealing systems from requirements and concept through detailed design, testing, failure analysis, and production release. Design precision moving parts, investigate coupled thermal, structural, materials, and fluid interactions, and run benchtop and in-generator test campaigns. Collaborate across engineering disciplines while applying mechanical engineering, thermodynamics, heat transfer, structural mechanics, tribology, and systems-level problem solving.

Leads post-deployment customer success for complex power-generation systems, serving as the primary customer contact and coordinating Engineering, Product, Operations, Field Service, and Commercial teams. Manages escalations, communicates technical performance and resolution timelines, tracks account health, drives satisfaction and retention, and develops scalable onboarding and account-management processes. Directly manages key B2B accounts while building the customer success function.

Leads hands-on investigations of electrical hardware failures, performs root cause analysis, and translates findings into corrective and preventive actions. The role improves failure-analysis throughput, documents diagnostic workflows and failure modes, collaborates with design, manufacturing, quality, reliability, and maintenance teams, and mentors junior engineers and technicians. Focus areas include power electronics, EMC/EMI issues, environmental degradation, thermal cycling, moisture, and system-level electrical interactions.

Leads a team of technical writers and establishes company-wide documentation standards, processes, tools, and revision control. Partners with Engineering, Manufacturing, and Field Service to translate complex mechanical and electrical systems into clear manuals, assembly instructions, and digital content. Oversees CAD-derived illustrations, schematics, and process flows, while mentoring writers and contributing hands-on to high-priority documentation projects.

Architects and scales automated test frameworks and CI/CD integrations for complex hardware and software systems. Creates validation workflows for cloud, networking, IoT, controls, simulations, and algorithms; performs root cause analysis and risk mitigation; and drives risk-based test coverage. The role partners closely with developers, conducts exploratory testing, designs technical test cases, and develops scalable solutions primarily in Python and C++ while using AI coding assistants responsibly.

Manage an embedded software engineering team developing Linux and real-time bare-metal applications for fuel-flexible linear generators. Lead team development, performance management, hiring, and career growth; oversee software lifecycle milestones and delivery; collaborate with product, executive, and QA stakeholders; and provide architectural and technical guidance during design reviews. The role requires extensive embedded software experience, commercial product delivery, project management, and Agile methodology expertise.

Designs and executes subsystem and system-level tests for Linear Generator electrical and software changes. Troubleshoots, retrofits, and operates test units; collaborates with technicians and engineering teams; analyzes data and reports results; manages testing priorities; and improves test processes and infrastructure for next-generation products.

Lead end-to-end technical program management for software in hardware-integrated products. Own integrated master schedules, drive cross-functional execution, enforce scalable engineering workflows, manage risks and budgets, and provide executive reporting on program health to ensure on-time delivery and validation readiness.

Lead root-cause analysis and redesign of mechanical components for durability and serviceability. Work hands-on at contract manufacturer to test, measure, rework, and validate improvements, integrate feedback into design and manufacturing processes, and support tooling and inspection efforts to improve product reliability.

Lead ~25 engineers and own 40-50% of a mechanical portfolio for a modular 250 kW-class linear generator. Drive risk mitigation, engineering review discipline (FMEA, DVP&R, tolerance analysis), supplier/manufacturing partnership, and development of future leaders to scale reliable power-generation hardware.

Lead the design of electrical enclosures and systems, manage engineers, and ensure project milestones through cross-functional collaboration.
