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 Test Engineer, you will be the primary interface between our Chemistry team and hardware - translating reaction chemistry into test protocols, validating that our reactors and process modules perform safely and predictably against the chemistry's requirements. The ideal candidate has previously owned test execution on hazardous or safety-critical chemical hardware end-to-end and is comfortable working shoulder-to-shoulder with chemists to bridge bench-scale reaction data and full-scale process performance.

Key Responsibilities

Own test planning and execution for ATP's reactors and modular process systems, from bench-scale trials through pilot and production-scale testing
Work directly with the Process Development team to translate reaction requirements, kinetics, and safety envelopes into test protocols and acceptance criteria
Design and run test protocols to validate process performance, yield, and safety margins under real operating conditions
Instrument test setups with sensors for pressure, temperature, flow, level, and concentration; capture and analyze data acquisition results
Execute hardware-in-the-loop testing, factory acceptance testing, and site acceptance testing on skidded process modules
Identify chemistry-driven failure modes and safety risks during testing; drive root cause analysis on test anomalies
Validate safety systems, interlocks, and fail-safe behavior under upset and off-nominal reaction conditions
Document test procedures, results, and deviations with the rigor required for a hazardous-chemistry, audit-ready environment
Feed test data and hands-on observations back to Chemistry and Process teams to refine reaction and design parameters
Support commissioning and startup of production systems at ATP and customer sites
Contribute to test plans, technical documentation, and engineering reviews
Travel to ATP sites, customer locations, and vendor facilities as needed

Required Qualifications

Bachelor's degree in Chemical Engineering, Process Engineering, or a related discipline
3+ years of professional experience in test engineering, process validation, or a comparable hands-on hardware role interfacing with chemistry
Demonstrated experience owning test execution end-to-end, from protocol design through data analysis and reporting
Working knowledge of reaction chemistry, kinetics, and how they translate to process operating envelopes
Hands-on experience with process instrumentation, data acquisition systems, and test equipment
Ability to work hands-on in laboratory, fabrication, and plant environments with hazardous materials
Strong documentation discipline and attention to detail
Strong problem-solving skills and ability to troubleshoot hardware and process issues quickly and rigorously

Preferred Qualifications

Experience testing chemical processes, batch processes, or other hazardous-chemistry systems
Familiarity with PLC/SCADA systems and reading control logic relevant to test execution
Experience with statistical analysis or data tools (Python, MATLAB, or similar) for test data analysis
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

ITAR Requirements

This position requires access to information and technology protected under U.S. export control laws and regulations, including the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR). To conform to these regulations, applicants must be a "U.S. Person" as defined by 22 CFR § 120.62, which includes (i) U.S. citizens or nationals, (ii) U.S. lawful permanent residents (green card holders), (iii) refugees under 8 U.S.C. § 1157, or (iv) asylees under 8 U.S.C. § 1158.
