## Job description

## Overview

You will build, assemble, and test the electronics that fly our two interceptor product lines. You’ll make wiring harnesses, assemble and rework circuit boards, and help integrate avionics into the vehicle and into test setups. You’ll report to the Head of Avionics.

You’ll also work alongside the mechanical, propulsion, GNC, and seeker teams. The hardware you build will go through testing and demonstration campaigns.

## What You’ll Do

Build hardware

- Fabricate wiring harnesses and cables from drawings and wiring diagrams, including cutting, stripping, crimping, soldering, and connector assembly.
- Assemble, solder, and rework circuit boards, including surface-mount and through-hole components.
- Assemble avionics boxes, test setups, and ground support equipment. Test and troubleshoot
- Test harnesses and boards using multimeters, continuity and hipot testers, oscilloscopes, and power supplies.
- Help engineers bring up new boards and track down hardware problems.
- Record test results and flag problems clearly. Integrate and support tests
- Install avionics and harnesses in the vehicle and in test setups.
- Support ground tests, static fires, and flight tests, including setup, checkout, and teardown. Keep the lab running
- Follow build procedures and record build and inspection results.
- Maintain the electronics lab, ESD controls, tools, and inventory of components and supplies.
- Suggest improvements to procedures, tools, and fixtures to make builds faster and more consistent.

Required Qualifications

- Associate degree, technical certificate, or military training in electronics or avionics, or equivalent experience.
- 2+ years of hands-on experience building or repairing electronics or wiring harnesses.
- Strong soldering skills, including surface-mount and through-hole work.
- Able to read schematics, wiring diagrams, and assembly drawings.
- Comfortable with multimeters, oscilloscopes, power supplies, and other basic test equipment.
- Careful, organized, and consistent in your work and records.
- Must be a U.S. person as defined by ITAR (U.S. citizen, lawful permanent resident, or protected individual). [Must be eligible to obtain a U.S. security clearance.]

## Nice to Have

- IPC certification (J-STD-001 or IPC/WHMA-A-620).
- Military avionics or aerospace electronics experience.
- Experience with aerospace or MIL-SPEC connectors and harnesses.
- Experience supporting vehicle integration or field tests.
- Prior early-stage startup experience.

## About wardstone.space

## Company Overview
- **One-liner**: Wardstone builds a modular, low-cost interceptor platform for air and missile defense, designed to counter threats from Group 4 UAS to medium-range ballistic missiles.
- **Entity Type**: Private (Seed stage; raised $5M)
- **Headquarters**: El Segundo, California, USA
- **Founded**: 2025
- **Founders**: Sebastian Fischer (CEO) and Tobias Fischer

## Core Business
- **Primary industries**: Aerospace & Defense, Missile Defense, Space-Based Interceptors
- **Target customers**: U.S. Department of Defense (Space Force, Missile Defense Agency, Air Force Research Labs), allied nations
- **Mission or purpose**: To out-produce, out-innovate, and out-perform adversaries by building a modular interceptor platform that can be mass-produced, rapidly adapted, and fielded at the pace of evolving threats.

## Products & Services
- **Hailstorm (Ground-Based Interceptor)**: A right-sized, modular surface-based interceptor demonstrated in the Mojave (Mach 2.5, 40,000 ft). Uses a large particle cloud (1 km diameter) to kinetically neutralize hypersonic and ballistic missiles, reducing cost and sensing requirements.
- **Space-Based Interceptor Constellation**: Satellites equipped with kinetic interceptors designed to counter hypersonic and ballistic missiles from orbit. Part of the “Golden Dome” concept.
- **Modular Platform Architecture**: Interchangeable components allow mission-specific configuration, rapid upgrades, and parallel production across multiple suppliers.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding — $5M seed round (raised from Nova Threshold, Liquid 2 Ventures, Bow Capital, B5 Capital, Allegis Capital)
- **Notable Investors/Partners**: Y Combinator (fall 2025 cohort), relationships with AFWERX, Space Systems Command, Air Force Research Labs, Navy Joint Special Operations Command
- **Growth Signals**: Accepted into Y Combinator; first prototype (Hailstorm-Ground) successfully flown; letters of support for a $3M SBIR grant; inbound requests for additional use cases; hiring multiple engineering roles.

## Competitive Advantages
- **Modularity**: Standardized, interchangeable components decouple production from single bottlenecks, enabling surge manufacturing and supply chain resilience.
- **Cost advantage**: Interceptors are designed to be “right-sized” to the threat, drastically reducing per-unit cost compared to traditional “exquisite” interceptors (e.g., THAAD, GMD).
- **Unique kill mechanism**: Large particle cloud increases probability of intercept without requiring precise hit-to-kill, reducing sensor and actuator costs.
- **Incremental path**: Starting with ground-based interceptors before scaling to space-based systems, allowing technology maturation and customer validation.

## Strategic Focus
- Near-term: Deliver ground-based interceptors to fill the “missing middle” threat band (Group 4 UAS to MRBMs) and secure SBIR/IRAD contracts.
- Medium-term: Deploy space-based interceptors as part of the U.S. “Golden Dome” missile defense architecture.
- Continuous improvement: Open architecture to integrate new technologies without redesigning the entire platform.

## Why Work Here
- **Mission-driven**: Direct impact on national security and countering hypersonic threats.
- **Early-stage startup**: Opportunity to shape the company’s technology and culture from the ground up.
- **Engineering focus**: Roles span mechanical, electrical, avionics, propulsion, GNC, simulation, and sensing.
- **Compensation & equity**: Competitive salaries ($100k–$160k for engineers) plus equity grants.
- **Location**: El Segundo, CA — a growing aerospace startup hub near LA Air Force Base and Space Force facilities.
- **Work environment**: Likely on-site/hybrid (El Segundo office); YC alumni culture with fast iteration and hands-on testing (e.g., Mojave flight tests).
