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

We are seeking a synthetic chemist to lead small-scale chemistry characterization and development. This role is the front end of ATP's technical pipeline: you will design and run the experiments that determine the details of our process. Where our process development team is focused on scale-up and piloting, you are focused on discovery, screening, and mechanistic understanding at the flask and small-reactor scale. Your ultimate deliverable will be to design and execute a well-controlled, well-characterized experimental campaign that de-risk core chemistry decisions before they reach the pilot plant stage. This position is highly independent, hands-on, and experimental.

Key Responsibilities:

  • Identify, design, and execute critical lab experiments with high rigor and precision, generating reliable, actionable data for reaction and unit-operation design and scale-up.

  • Develop and optimize synthetic routes (DoE, parametric optimizations) in tandem with our process development team

  • Characterize mechanisms of our chemistry and understand core failure modes

  • Develop and characterize reactions through off-line analytical method development and in-line analytics

  • Operate with a rigorous process-safety mindset, integrating hazard analysis and thermal/stability considerations into every stage of development.

  • Simplify complex things

Required Qualifications

  • B.S., M.S., or PhD in Chemistry, Organic Chemistry, Catalysis, or a related discipline

  • 5+ years of professional experience in synthetic chemistry

  • High proficiency with bench-top synthesis methods, laboratory practices

  • Basic analytical chemistry experience (NMR, HPLC, GC-MS, FTIR)

  • Strong problem-solving and debugging skills

Preferred Qualifications:

  • Experience with continuous-flow chemistry and reaction scale-up

  • Background in analytical chemistry for quality control: familiarity with method development on HPLC, IC, NMR, ICP-OES/MS, DSC/TGA, etc.

  • Prior experience developing with nitration chemistries, including hazardous or toxic material handling

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

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.
