# Mechanical Engineer at Traysar

- **Company:** Traysar
- **Location:** Austin, TX
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2025-12-23
- **Last confirmed live:** 2026-09-05
- **Apply:** https://jobs.ashbyhq.com/traysar/f981eb70-ffc0-4627-8a94-0236b58e2c6f

## Job description

Traysar was founded in 2025 by second time tech founders, recipients of the Israel Defense Prize, and engineers from elite military units, the Boring Company and SpaceX. Backed by Lux Capital and the founders of Anduril, the leading autonomous defense company, Traysar is reclaiming Western Deterrence by developing and deploying technologies for the 5th domain of warfare: the underground.

## JOB SUMMARY

Traysar is seeking a highly motivated Mechanical Engineer to join our team.

The machines you are responsible for designing and getting built will be used to destroy hundreds of miles of tunnels currently used for terrorist activities. The candidate will work alongside a product team of electrical and mechanical engineers and report to the team lead.

We are looking for an exceptional CAD engineer with outstanding SolidWorks (or NX) skills who is passionate about building real machines. The ideal candidate is early in their career, learns quickly, thrives in a fast-paced environment, and wants to take ownership of complex mechanical systems from concept through testing.

## RESPONSIBILITIES:

- Design, build, and test every mechanical aspect of the machine, including structures, hydraulic systems, and chassis components.
- Create high-quality 3D CAD models and manufacturing drawings for production, assembly, and testing.
- Own hardware through the product life cycle (design, analysis, build, and test) and interface with others to define design requirements and implement solutions. This includes soldiers in the field who will provide feedback to improve the machine.
- Design and integrate subsystems for an autonomous mechanical machine operating in tunnels.
- Research and select appropriate materials and manufacturing methods.
- Create and maintain detailed tracking spreadsheets for system mass, cost, and build schedules for piece parts and assemblies.
- Support qualification plans (e.g., acoustic, vibration, shock, static load, thermal testing) to verify structural and thermal safety margins and correlate results with analysis models.
- Work closely with production, suppliers, and technicians to rapidly iterate designs and solve engineering problems.

## BASIC QUALIFICATIONS:

- 3+ years of mechanical engineering experience.
- Bachelor's degree in Mechanical Engineering or equivalent hands-on engineering experience.
- Exceptional proficiency in SolidWorks or NX. This is a must-have.
- Strong experience creating complex 3D CAD models and detailed 2D manufacturing drawings.
- Strong understanding of mechanical design fundamentals and manufacturing processes.
- Highly motivated, self-driven, and eager to learn in a fast-paced startup environment.

## PREFERRED SKILLS AND EXPERIENCE:

- Experience designing heavy equipment, robotics, autonomous systems, or industrial machinery.
- Experience with hydraulic systems and mechanical integration.
- Demonstrated skills in FEA for structural analysis (ANSYS, FEMAP/Nastran, or similar).
- Experience designing for machining, sheet metal, welding, and additive manufacturing.
- Hands-on experience building, assembling, and testing mechanical systems.
- Strong problem-solving and troubleshooting skills.
- Excellent communication, teamwork, and organizational skills.
- A portfolio of personal, academic, or professional engineering projects demonstrating exceptional CAD and mechanical design ability.

## About Traysar

## Company Overview
- **One-liner**: Traysar engineers autonomous underground systems for strike and defense, aiming to secure U.S. military dominance in the subterranean domain.
- **Entity Type**: Private (Seed VC)
- **Headquarters**: Austin, Texas, United States
- **Founded**: 2025
- **Founders**: Yadin Soffer (CEO), Asher Katz, Gilad Adin

## Core Business
- **Primary industry/industries**: Defense technology, autonomous systems, subterranean warfare, military robotics
- **Target customers**: U.S. Department of Defense, allied military forces, government and defense-sector customers
- **Mission or purpose statement**: To transform the Earth’s crust into a three-dimensional maneuver space, exposing subterranean threats and equipping the armies of the free world to fight in the underground domain.

## Products & Services
- **Autonomous Tunnel Breaching & Tactical Exploration Platform**: An excavator-class autonomous platform that rapidly navigates, maps, and clears contested underground networks.
- **High-Speed Rapid-Burrowing Autonomous Platform**: Creates precision subterranean access points and delivers critical payloads beneath the surface.
- **Subterra Systems for Strike & Defense**: Full-spectrum capabilities including autonomy, persistent communications, mapping & localization, underground intelligence, distributed infrastructure, and geological intelligence.

## Market Standing
- **Valuation/Market Cap**: Not publicly available (private company)
- **Key Metric**: Total Funding — $25M (Seed round, raised as of June 2026)
- **Notable Investors/Partners**: Led by Silent Ventures; joined by Lux Capital, Ora Global, NeverLift VC, Mana, Impatient Ventures, New Vista Capital, Entree Capital, and strategic angel investors including Steve Blank, and founders from Anduril and Erebor among others.
- **Growth Signals**: Emerged from stealth at the 2026 Reindustrialize Summit; founded in 2025 and already raised a $25M seed round; engineering team includes early engineers from SpaceX and The Boring Company.

## Competitive Advantages
- **First-mover in a new domain**: Traysar is positioning itself as the world’s first "subterra defense tech company," addressing a massive capability gap in subterranean warfare that the global defense industry has largely ignored.
- **Unique technology stack**: Combines military boring, autonomous navigation in GPS-denied environments, and real-time underground mapping — capabilities that are extremely difficult to replicate.
- **Strong founder pedigree**: Co-founders and early engineers come from SpaceX, The Boring Company, Anduril, and other elite defense/engineering organizations.
- **Clear strategic relevance**: Addresses a documented threat — the U.S. Army estimates more than 10,000 known military facilities are hidden underground worldwide.

## Strategic Focus
- **Current priorities**: Developing and fielding autonomous platforms for subterranean maneuver and infrastructure survivability; building a complete suite of Subterra systems for strike, defense, protection, and denial operations.
- **Direction for growth**: Expanding from seed stage to operational deployment with the U.S. military and allied forces; hardening critical infrastructure and preserving logistical continuity under attack.

## Why Work Here
- **Mission-driven work**: The company describes itself as working on "the 21st century’s most important problem" — securing military dominance in a new domain.
- **Elite engineering culture**: The team includes early engineers from SpaceX and The Boring Company, suggesting a high-caliber, fast-paced, and technically challenging environment.
- **Early-stage impact**: As a seed-stage company founded in 2025, employees have the opportunity to shape the technology and culture from the ground up.
- **Location**: Headquartered in Austin, Texas, a growing tech and defense hub.
- **Notable perks**: Not explicitly stated, but the culture emphasizes working with "the best engineers" on a critical national security mission.
