Job Description

AT Process Technologies (ATP) is a pioneering manufacturing company focused on the development and deployment of modular energetics production plants. Using breakthrough chemistry and automation that operates continuously and generates little to no waste, ATP is expanding energetics production to meet the munitions demands of the US and Allies safely, rapidly, and cost effectively.

Summary

ATP is building a core team of engineers to work alongside our Process and Chemistry R&D teams to develop an autonomous skidded system for next-generation energetics manufacturing. In this role you will own and deliver a subsystem from concept through commissioning. The ideal candidate has previously owned a critical project end-to-end (design, build, and execution) and brings the engineering fundamentals to solve a wide range of problems quickly and rigorously.

Key Responsibilities

• Own the mechanical design and development of subsystem-level hardware from concept through pilot testing and production

• Design and fabricate reactors and other continuous process systems.

• Work alongside a team of mechanical and process engineers to design, build, test, and commission hardware

• Collaborate with automation and controls engineers on integrated system development

• Lead hands-on testing, hardware iteration, and rapid prototyping based on performance feedback

• Drive manufacturability, part selection, and tolerance stack-up decisions for scalable production

• Conduct engineering analysis including stress, thermal, and fluid modeling; perform DFM and DFMEA

• Evaluate vendors, lead design reviews, and validate compliance and performance

• Contribute to test plans, technical documentation, and engineering reviews

Required Qualifications

• Bachelor's degree in Mechanical Engineering, Chemical Engineering, Robotics, Mechatronics, or a related discipline

• 5+ years of professional experience in hardware design and development

• Strong proficiency in 3D modeling and CAD tools (Siemens NX, Fusion 360, or equivalent)

• Demonstrated application of mechanical fundamentals - structural, thermal, and materials - to deliver robust, well-engineered designs

• Demonstrated experience owning hands-on, end-to-end hardware development efforts (industry projects, FSAE, Design-Build-Fly, rocketry teams, or similar)

Preferred Qualifications

• 5-10 years of relevant industry experience

• Background in robotics, PLCs, mechatronics, or process development

• Experience with continuous processes and manufacturing

• Familiarity with at least one programming language (Python, C++, or similar)

• Experience designing hardware for reactive, hazardous, or energetic chemistries

Additional Requirements

• Ability to lift 50 lbs

• Ability to obtain a U.S. Government security clearance

• Ability to work on-site and travel as needed

Export Control Requirements

This position may require access to information or technology subject to U.S. export control laws and regulations, including the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR). Accordingly, employment may be conditioned upon the ability to obtain any export authorization required for this role. Non-U.S. persons are not automatically excluded from consideration; if an export license is required, the company will evaluate the feasibility of obtaining one for the selected candidate. If required, citizenship information will be collected as part of the standard background check process, and a separate export compliance review will be conducted for this position prior to the start date, independent of the Form I-9 employment eligibility verification process.
