Mechanical Engineer

AAPPTec, a TCPA Company is a peptide research and industrial-scale production facility.

Reporting to the Sr Engineer for Operations, this multi‑skilled Engineer will build, assemble, test, install, and service our peptide synthesizers. This is a hands‑on, end‑to‑end role directly responsible for some design work and turning raw components into fully operational instruments—and ensuring they keep running smoothly in the field.

• Assemble complete peptide synthesizers from mechanical, electrical, pneumatic, and control components.
• Install wiring, tubing, and subsystems according to engineering schematics and assembly drawings.
• Integrate software, firmware, and hardware elements into a functional system.

• Conduct full functional tests, calibrations, and performance verification on every unit before shipment.
• Simulate operational workflows to ensure compliance with design specifications and reliability standards.
• Document test results and resolve any discrepancies before delivery.
• Deliver and install instruments at customer sites, ensuring proper setup and operational readiness.
• Provide user training on operation, care, and preventive maintenance of the equipment.

• Develop and execute preventive maintenance schedules for deployed instruments.
• Troubleshoot and repair mechanical, electrical, and software‑related issues on‑site or via remote support.
• Collaborate with design engineers to suggest improvements based on field performance and assembly experience.
• Identify recurring faults and propose design or procedural solutions to increase reliability and ease of service.
• Track key performance indicators (KPIs) and report on supply‑chain performance.

• Bachelor’s degree Mechanical Engineer with a min 5 years' experience in design lab instrumentation. Knowledge of software for Mechanical Desktop, Inventor, Solid Works, Microsoft Project, and Microsoft Office is required.
• Skilled in reading technical drawings, wiring diagrams, and pneumatic schematics.
• Proficient with test instruments (multimeters, pressure gauges, calibration tools) and hand/power tools.
• Strong problem‑solving skills and ability to work independently from start to finish on a project.

• Experience with laboratory automation, peptide synthesis, or similar chemical process instrumentation.
• Knowledge of ISO or GMP manufacturing standards.
• PLC programming or embedded control system familiarity.

• Solid‑phase peptide synthesis principles and instrumentation.
• Pneumatic, hydraulic, and fluid handling systems.
• Electronics and electrical systems used in automated laboratory equipment.
• Calibration procedures for sensors, pumps, and automated dosing systems.
• Software‑controlled instrumentation and embedded system operations.

• Precision mechanical assembly and alignment.
• Electrical wiring, soldering, and connector fabrication.
• Reading and interpreting complex engineering drawings and schematics.
• Diagnosing faults using test equipment and logical troubleshooting steps.
• Using CAD files and assembly documentation for manufacturing processes.

• Manage full project lifecycle from assembly through delivery.
• Train customers in technical operation and maintenance procedures.
• Adapt to changing production priorities in a small‑team environment.
• Work independently with minimal supervision while maintaining quality standards.
• Communicate effectively with engineers, technicians, and end‑users.
