Mechanical Engineer, Associate

Allen Control Systems•Austin, TX

About The Position

Allen Control Systems (ACS) is a cutting-edge defense startup founded by two former Navy electrical engineers with a proven track record in robotics and software. We are developing an autonomous gun turret using advanced computer vision and control systems to precisely detect, track, and neutralize enemy drones. With an engineering-first culture, ACS values technical excellence and innovation. Backed by our founders’ successful exits from two previous ventures acquired for a combined $180M in 2022, we are committed to ensuring that the groundbreaking technologies we develop will have a real-world impact. We are looking for an Associate Mechanical Engineer to join the ACS team and contribute to the design and development of our autonomous counter-drone platform. This is an early-career role well suited for a recent graduate or engineer with up to 2 years of experience who has a strong foundation in mechanical design, simulation, and electromechanical integration. You will work alongside senior engineers on real hardware that operates in demanding environments, learning fast and contributing from day one.

Requirements

Bachelor’s or Master’s degree in Mechanical Engineering or a related field.
Proficiency in 3D CAD software such as SolidWorks (preferred), CATIA, or Creo; coursework or hands-on experience with FEA, modal, and thermal simulation tools such as ANSYS or SolidWorks Simulation.
Foundational understanding of MIL-STD-810 requirements for mechanical durability including vibration, shock, temperature, and humidity testing.
Interest in electromechanical integration and an eagerness to learn how mechanical structures interact with electrical systems such as sensors, actuators, and wiring harnesses.
A passion for designing robust mechanical systems for harsh environments and a strong desire to work on hardware that has real-world defense impact.

Nice To Haves

Any direct exposure to MIL-STD-810 testing such as vibration, temperature, or shock, including through coursework, internships, or research projects.
Familiarity with EMC considerations in mechanical design, or awareness of MIL-STD-461 and MIL-S-901D standards.
Hands-on experience with rapid prototyping or additive manufacturing through personal projects, capstone work, or internships.
Background or interest in fluid dynamics, heat transfer, or shock absorption systems.

Responsibilities

Support design and development of mechanical systems under MIL-STD-810 specifications, including robustness under vibration, shock, thermal, and environmental conditions.
Run mechanical simulations including FEA, modal, vibration, and thermal analysis to assess durability and reliability of designs under operational stress.
Collaborate with electrical and systems engineers to integrate electromechanical components including wiring harnesses, sensors, and actuators into mechanical structures.
Support prototype development, testing, and validation; help develop and document mechanical design specifications, drawings, simulation reports, and test protocols.
Participate in cross-functional design reviews, applying DFM and DFR principles and helping identify mechanical and electromechanical risks early in the development cycle.
