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 develop the autonomous skidded production systems that will redefine how energetics are manufactured. As our Systems Engineer, you will own the integration point between chemistry, process, mechanical, and controls — defining requirements, architecting how subsystems fit together, and making sure the whole system works as one, not just as a collection of parts. The ideal candidate has previously owned systems-level integration on a real hardware program end-to-end and brings the discipline to engineer for safety in a hazardous-chemistry environment.

Key Responsibilities

• Own systems engineering for ATP's modular energetics production plants, from requirements definition through integration, verification, and commissioning

• Translate process and chemistry requirements into system-level architecture, interface definitions, and technical specifications

• Define and manage interfaces between mechanical, controls, process, and chemistry subsystems to ensure clean integration

• Lead requirements traceability, ensuring design decisions map back to functional, safety, and performance requirements

• Conduct system-level trade studies and risk analyses (FMEA, hazard analysis) across mechanical, electrical, and process domains

• Develop and maintain system architecture diagrams, interface control documents (ICDs), and technical baselines

• Coordinate design reviews across engineering disciplines, identifying integration risks before they reach the build

• Support verification and validation planning, ensuring test coverage maps to system requirements

• Lead or support hands‑on integration, commissioning, and factory/site acceptance testing across subsystems

• Drive root cause analysis on system‑level anomalies that span multiple engineering disciplines

• Collaborate with Process, Chemistry, Mechanical, and Controls engineers to keep the full system on schedule and within scope

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

Required Qualifications

• Bachelor's degree in Systems Engineering, Mechanical Engineering, Chemical Engineering, Electrical Engineering, or a related discipline

• 2+ years of professional experience in systems engineering, integration engineering, or a comparable cross‑disciplinary technical role

• Demonstrated experience owning systems‑level integration end‑to‑end on real industrial or hardware programs

• Strong grasp of engineering fundamentals across mechanical, process, and controls domains, with the ability to reason across disciplines

• Experience with requirements management, interface control, and technical documentation practices

• Ability to work hands‑on in laboratory, fabrication, and plant environments

• Strong problem‑solving skills and the ability to work through ambiguity quickly and rigorously

Preferred Qualifications

• 5-10 years of relevant industry experience

• Experience with systems engineering tools and methods (DOORS, MBSE, SysML, or equivalent)

• Background in continuous process systems, batch processes, or other hazardous‑chemistry environments

• Experience integrating mechanical, controls, and process subsystems on a skidded or modular equipment program

• Familiarity with safety and reliability standards (ISO 13849, IEC 61508, or similar)

• Experience in defense, aerospace, energetics, or other regulated manufacturing environments

Additional Requirements

• Ability to lift 50 lbs

• U.S. Person and ability to obtain a security clearance

• Ability to work on-site and travel as needed
