Technical Writer

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.

As we bring new equipment and processes online across multiple sites, clear, accurate, and well-controlled documentation is essential to operating safely, training our team, and meeting the expectations of our regulators and customers.

We are seeking a Technical Writer to own the documentation that underpins ATP’s engineering projects and manufacturing operations. You will write standard operating procedures for our process equipment, maintain project documentation as our facilities are designed and commissioned, and develop the policies and procedures that govern how we work. You will not be inheriting an established document library; instead, you will build the templates, standards, and document control system that let ATP document its operations consistently as we scale.

Critical Responsibilities

• Standard Operating Procedures: Write, revise, and maintain SOPs for ATP’s process equipment and manufacturing operations, including startup, normal operation, shutdown, emergency shutdown, cleaning, and maintenance. Work directly on the floor and in the lab with engineers, chemists, and operators to walk down equipment and capture how work is actually performed.

• Regulatory-Grade Operating Procedures: Ensure procedures meet the requirements of OSHA Process Safety Management (29 CFR 1910.119), DoD 4145.26-M explosives operating procedure requirements, and applicable ATF and state regulations, in partnership with the Lead Safety Officer and Compliance team.

• Project & Engineering Documentation: Own the documentation for capital and engineering projects, including design basis documents, system descriptions, equipment and instrument lists, commissioning and turnover packages, and as-built updates. Keep project records organized and current as designs evolve.

• Policies & Procedures: Draft and maintain company-wide policies and procedures across safety, security, quality, and operations, working with the Lead Safety Officer, Facility Security Officer, Head of HR, and General Counsel to turn requirements into clear, usable documents.

• Document Control System: Build and administer ATP’s document control system from the ground up: numbering, templates, style standards, review and approval workflows, revision history, periodic review schedules, and controlled distribution across our Massachusetts, Maine, and Louisiana sites.

• Training Materials: Convert SOPs and policies into training materials, job aids, checklists, and operator qualification records that support onboarding and recurring training.

• Customer & Government Deliverables: Support the preparation of technical reports, proposal and RFI responses, and other deliverables for government and prime contractor customers, ensuring consistency, clarity, and compliance with export control and marking requirements.

Qualifications

• Technical Writing Experience: 5+ years of technical writing in a regulated manufacturing environment such as chemical, pharmaceutical, energetics, defense, or aerospace, with a portfolio of SOPs or operating procedures you have authored.

• Process & Equipment Literacy: Comfortable reading P&IDs, equipment drawings, and process descriptions, and able to hold your own in conversations with process engineers and chemists. A technical degree or hands-on plant experience is a strong plus.

• Regulated Documentation: Working familiarity with OSHA PSM, ISO 9001, cGMP, AS9100, or comparable document control and procedure frameworks. Experience with explosives or energetic materials operations is a plus.

• The "Builder" Profile: Experience standing up templates, standards, and document control systems for a growing organization, rather than only working within an established one.

• Field-Ready Mindset: Willing to spend significant time on the shop floor, in the lab, and at our pilot site observing operations and validating procedures with the people who use them.

• Eligibility & Travel: Must be a U.S. person as defined under ITAR. Eligibility to obtain and maintain a U.S. Government security clearance is preferred. Ability to travel regularly between Waltham and Berwick and occasionally to Louisiana.

• Tools: Proficiency with Microsoft Office and modern documentation tools. Experience with an electronic document management system (e.g., SharePoint, MasterControl, Veeva, or similar) and basic graphics or diagramming tools is preferred.

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
