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.

Design, build, and scale cloud-native infrastructure across multi-cloud environments. Lead Terraform-based infrastructure as code, modernize CI/CD pipelines, automate operational support with Python and AI agents, and manage Kubernetes, Helm, containers, serverless, and microservices. Own projects from conception through production, establish security controls and AI guardrails, improve reliability and developer velocity, document architectures and runbooks, and mentor engineering teams.

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.

The Test Engineer will perform hands-on testing on Linear Generator units, develop testing processes, analyze data, and collaborate with engineering teams.

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.

Leads an embedded software engineering team developing Linux and real-time bare-metal systems for sophisticated linear generators. Responsibilities include setting technical roadmaps, managing engineers, overseeing software development, establishing architecture and quality standards, providing technical guidance, collaborating cross-functionally, and hiring and developing talent.

Develop and validate dynamic models and simulation environments for linear generators and control systems. Write ODE and DAE solvers, reduced-order models, and computational models in Python and C++. Coordinate with controls and test engineers, create test plans, oversee generator testing, debug controller integrations, optimize real-time simulations, participate in code reviews, and document modeling results for technical and executive audiences.

Develop and optimize sales outreach processes, manage customer campaigns in SalesLoft, train and onboard SDRs, create segment-specific growth marketing campaigns, analyze targeting and campaign performance, and support market strategy and AI-driven process optimization. The role collaborates with sales, brand marketing, and revenue operations teams while communicating outreach strategies and targeting analysis to stakeholders, including C-suite leaders.

Lead design and launch of electrical enclosures and cable systems for the Linear Generator.
