Technical Executive Assistant

Mattur is building a new class of modular power systems that deliver reliable, low-cost energy anywhere it's needed. Our platform starts with PulseTech - a high-efficiency generator core used across our portable and backup hybrid-fuel systems and our compact utility wind turbines - giving customers scalable power without the constraints of traditional solutions. Mattur systems operate where legacy equipment struggles: low-wind environments, remote sites, fast-growing operations, and markets where power availability limits growth. With faster installation, lower operating cost, and real-time optimization through our control software, we provide dependable power for construction, mission-critical backup, rural communities, and the next generation of AI and industrial load. At Mattur, we're reinventing distributed energy - systems that are cleaner, smarter, and resilient by design. Join us as we build the next generation of American-made power. Position Overview Mattur is seeking a Technical Executive Assistant to support our Chief Technology Officer and keep the day-to-day engine of our R&D operation running. This person is the CTO's right hand - managing their calendar, inbox, and travel, sitting in on key meetings to capture decisions and action items, and making sure nothing falls through the cracks. The role also carries a lighter set of R&D procurement and office responsibilities that round out the CTO's support system. It's a high-trust, high-variety role for someone exceptionally organized and eager to learn how a hardware company gets built from the inside - a great fit for someone early in their career ready to sit at the center of the action. Key Responsibilities Executive Support to the CTO Own the CTO's calendar - scheduling, prioritizing, and resolving conflicts across engineering, manufacturing, and leadership commitments. Manage the CTO's inbox - triaging messages, drafting responses, and flagging what needs personal attention. Prepare agendas, briefings, and background research so the CTO walks into every conversation prepared. Coordinate travel, expenses, and ad hoc logistics for the CTO and leadership as needed. Help keep the CTO on track day-to-day - reminders on deadlines and priorities, and keeping meetings moving and on time. Meeting Shadowing & Follow-Through Shadow the CTO through key meetings, capturing clear notes, decisions, and action items and circulating follow-ups to the right owners. Track commitments the CTO makes across engineering, manufacturing, and operations - chasing down owners and surfacing anything at risk of slipping. Maintain a running log of open items and decisions so there's always a single source of truth. Support procurement of materials, components, and equipment for the R&D team - helping manage supplier relationships, purchase orders, lead times, and inbound logistics to prevent delays. Help source and qualify suppliers for mechanical, electrical, and specialty hardware; support RFQs and help maintain a preferred vendor list. Maintain inventory tracking for R&D materials - accurate records of stock levels, component locations, and material movement. Partner with engineering to track BOMs and support engineering change orders (ECOs) ahead of prototype and development builds. Office & Operations Support Support day-to-day office operations at Mattur's Phoenix HQ - supply ordering, facility coordination, and vendor relationships. Support new-hire onboarding logistics - equipment setup, badge access, workstation readiness, and coordination with IT and HR. Handle inbound mail, packages, and shipment receiving, routing items to the right teams. Qualifications 0-3 years of experience supporting an executive, in an operations or administrative role, or in a technical or fast-paced environment (internships count); eager to learn how a hardware company operates from the inside. Bachelor's degree (technical or business field a plus, but not required). Exceptional organization, note-taking, and follow-through; nothing slips through the cracks on your watch. Proven ability to manage a busy calendar, inbox, and travel schedule with sound judgment and discretion. Technically curious - able to follow engineering and hardware conversations closely enough to capture what matters. Comfortable leaning on AI tools to move faster and stay organized. Strong Excel skills - comfortable building and maintaining trackers, working with formulas, and organizing data cleanly. Quick to pick up new systems (calendar and travel tools, ERP/MRP, Asana, Notion, and similar). Strong written communication, high discretion with sensitive information, and sound judgment on what to elevate versus handle. Proactive, resourceful, and comfortable with ambiguity in a fast-paced startup. Based in Phoenix, AZ; this is a full-time, on-site, hourly role. What We Offer Competitive hourly compensation. A rare, close-up view of how a hardware startup is built - and a path to grow into an expanded role. Comprehensive benefits package, including health, vision, dental, and life insurance plans. A mission-driven team building next-generation American-made power. #J-18808-Ljbffr Mattur
