Inspects, examines, and tests electrical and mechanical MEP components during mission-critical construction projects. Records test results, verifies equipment condition, reviews QA/QC plans and procedures, coordinates inspection activities, and prepares reports. The role requires strong communication, organization, problem-solving, leadership, and the ability to work from a home office while traveling frequently to project sites and performing strenuous physical tasks.

Performs optical testing and metrology for light-adjustable intraocular lens products, including interferometry, MTF, and other measurements. Supports nomogram development, experiment design, data analysis, engineering documentation, prototype testing, equipment calibration, and the design and fabrication of optical and optomechanical fixtures. Collaborates with engineering teams to modify hardware and develop new products based on light-adjustable materials technology.

Supports the design, development, testing, and deployment of mechanical structures and systems for aerospace and defense applications. Responsibilities include designing components, creating test plans, performing analyses and simulations, preparing technical documentation, collaborating with engineering teams, and troubleshooting design or testing issues.

Design and validate embedded electronic hardware for high-precision GNSS and communications products. Responsibilities include board architecture, component selection, schematic creation, PCB layout, mixed-signal validation, design verification, lab testing, automated debugging, and integration of sensors, power management, and circuit protection. The role requires collaboration across engineering teams from initial concept through production.

Develop embedded and robotics software for semiconductor automation systems, including motion control, vacuum subsystem interfaces, diagnostics, data collection, analytics, and monitoring. Apply machine learning and AI to improve performance and reliability. Collaborate with engineering, product, manufacturing, field service, and customers; define requirements, participate in design reviews, implement automated testing, support DevOps improvements, and troubleshoot field issues.

Creates and modifies mechanical drawings from SolidWorks models, develops basic sales models, interprets hydraulic and electrical schematics, and prepares equipment manuals and bills of materials. The role also facilitates engineering change requests, follows drafting standards, communicates with stakeholders, and supports project execution. Strong mechanical aptitude, drafting software experience, technical writing, attention to detail, and hands-on shop experience are important.

Supports planning, design, integration, and delivery of rail and transit systems. Manages system requirements, coordinates interfaces across signaling, communications, vehicles, civil, track, power, operations, and maintenance teams, and supports configuration management, verification and validation, testing, commissioning, risk management, and operational readiness.

Build and maintain core products and collaborate on larger consulting projects using TypeScript, Python, FastAPI, Next.js, GCP, and generative AI frameworks. The role involves hands-on software development within a rapidly growing, remote team serving Saudi Arabia and the GCC.

Provides remote technical support for customer production, cleaning, data collection, and reporting systems. Troubleshoots issues, configures and programs PLC and HMI changes, documents resolutions, communicates with customers, follows change-control and safety procedures, and escalates complex or high-impact problems. The role requires developing proficiency in automation technologies and working scheduled 12-hour night shifts with rotating weekends.
