Process Design Engineer

Work tasks: Engineerly OÜ is looking for a Process Design Engineer to support the design and engineering of industrial process systems. The role focuses on core process calculations and deliverables including pump selection, process documentation (PFD/P&ID), and instrument/equipment sizing to ensure safe, reliable, and efficient operation.

Key responsibilities • Perform process calculations: flow, mass balance, velocity, pressure drop, line sizing, and hydraulic checks
• Select and size pumps (duty point, NPSH, curves, efficiency, margins) and specify pump datasheets
• Develop and update PFDs and P&IDs in line with project standards
• Select and size key instruments and control elements (flow/pressure/level/temperature measurement, control valves)
• Prepare equipment and instrument datasheets, line lists, and process design notes
• Define operating/design cases, utilities requirements, and control philosophies as needed
• Coordinate with piping, mechanical, E&I, and HSE disciplines; participate in design reviews (HAZID/HAZOP if applicable)
• Support vendor technical evaluations and clarify technical queries during procurement

We offer: Remote work possability

Other requirements: Required qualifications

• Degree in Chemical Engineering, Process Engineering, Mechanical Engineering (process-focused), or similar
• Proven experience in process design/calculations and P&ID development
