Polysciences is seeking a Process Engineer who enjoys working directly with equipment, solving practical problems, and learning alongside experienced technical partners.\nOur specialty chemical manufacturing environment uses batch processing. You will develop batch processes in both our 2-gallon and 20-gallon high pressure reactors, while collaborating cross-functionally internally and with an external consulting firm. You will work closely with the team to improve process efficiency through onboarding equipment upgrades, completing DOEs, and demonstrating batch-to-batch process capability.\nWe are looking for a foundation of relevant reactor experience, sound engineering knowledge and judgment, and a willingness to learn. You do not need to arrive as a high-pressure processing expert. You do need to be ready to work with the team and equipment, ask questions and steadily develop into an internal subject matter expert.\nScope of Role (What the work looks like)\nExpect to regularly spend time in both research and production areas working with manufacturing technicians, R&D scientists and engineers to complete, observe and improve batch reactions. Work scope includes designing reaction processes, observing and monitoring reactions, fine tuning and troubleshooting process conditions and equipment, and continuous improvement of process, equipment and product for new product implementations. This role combines engineering design of equipment and process, data analysis for statistical process control, documentation to ensure a robust and repeatable process and direct hands-on work with the high-pressure equipment.\nIn this role you will get to gather information directly and indirectly, coordinate efforts cross-functionally, and identify and solve problems to design, develop, troubleshoot, improve and launch processes, systems and equipment for new product introductions. Experience at a large, small or medium-sized company can translate well if you are comfortable with this practical, resourceful and hands-on way of working to meet the day-to-day demands of batch manufacturing. Salary and title are based on experience and education.\nResponsibilities (What you will do)\nProvide hands-on engineering support for high-pressure batch reactors, associated equipment, and process troubleshooting.\nWork with a cross-functional team, including but not limited to, engineers, R&D scientists, process technicians, quality and experienced consultants to understand and control process behavior and improve process robustness and equipment performance.\nDesign and complete process trials and collect data; evaluate, select, install and qualify equipment; scale-up, validate and transfer processes to commercial production team; and ensure processes for production, equipment and cleaning are well defined and robust. \nComplete experiments and DOEs, analyze data and evaluate reaction parameters (pressure, temperature, time, materials, etc.) to establish robust processes that consistently adhere to high product quality standards. \nBuild a thorough understanding of the reactor systems and processes to become an experienced, dependable high-pressure reaction SME. Leverage this knowledge to support other manufacturing areas as needed. \nIdentify, recommend and coordinate the procurement, installation and qualification of engineering equipment, capital project improvements with a cross-functional internal team and with external suppliers, manufacturers, experts, etc.\nDevelop and update process and cleaning instructions, SOPs, equipment specifications, PFDs, P&IDs, and technical reports; support technician training as your expertise develops.\nParticipate in process safety reviews, risk assessments, root cause investigations, change control, equipment qualification and validation activities within our ISO 13485 quality system.\nRequirements (What you will bring)\nA bachelor’s degree in Chemical Engineering.\nDirect, hands-on experience with high-pressure chemical reactors, including smaller batch, pilot, or specialty chemical systems. \nA thorough understanding of past equipment systems to be able to communicate equipment set up, operation, and the associated safety considerations and controls needed for operation. \nExperience in designing, overseeing and carrying out reactor operations, process trials, process and product development and data analysis for statistical process control.\nExperience in equipment design, procurement, installation and qualification. \nA minimum of 3-5 years of industry experience in chemical engineering for practical application understanding of heat transfer, reaction kinetics and thermodynamics, batch scaling and critical parameters (mixing rates, pressurization, rate of reaction, etc.).\nWillingness to work directly in a manufacturing environment, leaning new equipment and systems through training, research and supervised experience; seeking guidance when needed.\nA methodical approach to problem solving, clear communication, concise, complete and accurate documentation, and the ability to work with a cross-functional team. \nRelated Experience (Helpful experience)\nBatch chemical manufacturing.\nEquipment and process scale-up. \nTechnology transfer of existing processes and to production teams.\nCapital Equipment projects including the creation, review or approvals of Design Specifications, PFDs and P&IDs, process risk assessments, change controls, and installation documentation (FATs, SATs, IOPQs).\nExperience in an ISO 13485, ISO 9001, GMP, or other structured manufacturing quality environment.\nWhy this opportunity\nThis is an opportunity to further develop specialized reactor knowledge while contributing directly to a growing manufacturing capability. You will learn from internal teams and external specialists, work closely with the team running the process, and see the results of your engineering work at the equipment. We value curiosity and initiative, paired with the judgment to recognize limits, raise concerns, and put safe operation first.\nWhen applying, please highlight the reactor systems you have worked with, whether they were batch or continuous, and what you personally did at the equipment. We are especially interested in candidates who want to build their careers around practical reactor and process engineering.\nQualifications\nQualifications\nEducation Required: Bachelor's Degree-Chemical Engineering\nComputer Skills Required: Specify preferred or required.\nProficiency with Microsoft Word and Excel required.\nExperience with statistical software such as Minitab, JMP or Stat-Ease preferred.\nFamiliarity with SAP or similar ERP system and Blue Mountain or similar CMMS preferred.\nOther qualifications: \nA bachelor’s degree in Chemical Engineering.\nDirect, hands-on experience with high-pressure chemical reactors, including smaller batch, pilot, or specialty chemical systems. \nA thorough understanding of past equipment systems to be able to communicate equipment set up, operation, and the associated safety considerations and controls needed for operation. \nExperience in designing, overseeing and carrying out reactor operations, process trials, process and product development and data analysis for statistical process control.\nExperience in equipment design, procurement, installation and qualification. \nA minimum of 3-5 years of industry experience in chemical engineering for practical application understanding of heat transfer, reaction kinetics and thermodynamics, batch scaling and critical parameters (mixing rates, pressurization, rate of reaction, etc.).\nWillingness to work directly in a manufacturing environment, leaning new equipment and systems through training, research and supervised experience;
