# Production Engineer – Hydraulic Systems at Traysar

- **Company:** Traysar
- **Location:** Austin, TX
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2025-12-23
- **Last confirmed live:** 2026-09-05

## 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 and experienced Production Engineer with deep expertise in hydraulic systems to join our team. This is a hands-on role focused on designing, building, integrating, and commissioning the hydraulic systems that power our autonomous heavy machinery.

The ideal candidate has extensive experience building hydraulic circuits from the ground up, selecting and integrating hydraulic components, plumbing complete hydraulic systems, and commissioning hydraulic power packs for heavy equipment or industrial machinery. The machines you help build will be deployed to destroy hundreds of miles of tunnels currently used for terrorist activities.

You will work alongside a multidisciplinary team of mechanical, electrical, and controls engineers and report to the Mechanical Team Lead.

## RESPONSIBILITIES

- Own the design, build, and integration of complete hydraulic systems for autonomous heavy machinery.
- Design and assemble hydraulic circuits, including hose routing, manifolds, valves, pumps, motors, cylinders, filters, reservoirs, accumulators, and instrumentation.
- Specify, size, source, and integrate hydraulic power units (HPUs) and power packs to meet system performance requirements.
- Develop hydraulic schematics and ensure they are translated into reliable, manufacturable hardware.
- Coordinate the transition from detailed design to manufactured hardware, taking full responsibility for bringing hydraulic systems into production.
- Serve as the primary interface with hydraulic suppliers, hose manufacturers, machine shops, fabrication vendors, and other external partners.
- Review and approve manufacturing drawings, hydraulic schematics, BOMs, and assembly documentation before release.
- Lead on-site assembly, plumbing, commissioning, bleeding, flushing, and troubleshooting of hydraulic systems.
- Diagnose and resolve hydraulic issues including pressure losses, flow restrictions, leaks, heat generation, contamination, and system instability.
- Develop assembly procedures, inspection plans, test procedures, and production documentation for hydraulic systems.
- Track component procurement, supplier lead times, system weight, cost, and production schedules.
- Support machine testing, validation, and field operations, incorporating lessons learned into future designs.

## BASIC QUALIFICATIONS

- 7+ years of professional experience working with hydraulic systems.
- Degree in Mechanical Engineering or a related engineering discipline, or equivalent hands-on industry experience.
- Extensive experience designing, building, plumbing, and commissioning hydraulic systems for heavy equipment, mobile machinery, construction equipment, mining equipment, agricultural equipment, or industrial machinery.
- Strong mechanical background with hands-on experience assembling and troubleshooting hydraulic equipment.
- Experience reading and creating hydraulic schematics and mechanical drawings.
- Experience working from 3D CAD models and 2D manufacturing drawings.

## PREFERRED SKILLS AND EXPERIENCE

- Extensive experience designing and assembling complete hydraulic power packs (HPUs).
- Strong understanding of hydraulic pumps, motors, proportional valves, servo valves, manifolds, accumulators, pressure control, flow control, filtration, and cooling systems.
- Experience selecting hydraulic components based on pressure, flow, duty cycle, efficiency, and reliability requirements.
- Experience routing hydraulic hoses and tubing for serviceability, manufacturability, and reliability.
- Hands-on experience commissioning hydraulic systems, including flushing, bleeding, contamination control, and performance tuning.
- Experience troubleshooting complex hydraulic systems under field conditions.
- Experience working directly with hydraulic suppliers and component manufacturers.
- Strong understanding of manufacturing processes, tolerancing, and Design for Manufacturing (DFM/DFA).
- Experience working with CNC machining, welding, fabrication, sheet metal, and additive manufacturing suppliers.
- Proficiency with NX or SolidWorks.
- Experience taking complex electromechanical systems from prototype through production.
- Strong organizational, communication, and cross-functional coordination skills.

## INTERVIEW PROCESS

If there is a mutual fit, we'll schedule two technical interviews. During the second interview, you'll present a project you are particularly proud of, with a strong emphasis on the hydraulic or mechanical systems you personally designed, built, integrated, or commissioned. Candidates who successfully complete the technical interviews will be invited for a final on-site interview.

## 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
