Circular Loom Specialist

PT Aerae Manufacturing Indonesia · Kabil Integrated Industrial Estate (KIIE), Batam - Indonesia

About us

We design and build precision electromechanical hardware in Batam, Indonesia — robotics-grade structures and drivetrains, and woven inflatable structures from high-tenacity HDPE/PE slit tape. We are commissioning and scaling circular-weaving capability in Batam. Our team includes experienced, senior engineers from aerospace and advanced manufacturing around the globe, and our in-house prototype machine shop puts your parts in your hands within days of releasing the drawing.

The role

We are looking for a Circular Loom Specialist — the company's principal technical authority for circular loom setup, high-speed weaving, reliability and process optimization. You will own the loom and its upstream tape feed hands-on — setup, parameter tuning, maintenance strategy, modification and automation — and set the standard for the technicians around you through on-the-job guidance. This is a senior hands-on specialist role, not a supervisory position and not commodity sack weaving: you will work on non-standard tape specifications in an R&D setting.

What you will own

• Machine setup and commissioning. Lead technical setup, changeovers and optimization of circular looms for new and existing fabric specifications — warp count and layout, weft density (picks/inch), shuttle configuration, tape tension, take-up speed and other critical process parameters — and lead installation, commissioning, acceptance testing and performance validation with the OEM.

• Parameter tuning for high-speed operation. Tune warp tension, weft density and take-up to hold fabric spec at production speed, and read machine condition by sound, vibration and fabric quality.

• High-speed machine operation. Run the loom at production speed during trials and campaigns, and establish the operating windows and process standards the team works to.

• Machine modification and automation strategy. Plan and lead machine modification and the automation strategy for the loom line: define what to automate and in what order, design the improved parts, and drive the work with our in-house machine shop and automation teams.

• Mechanical reliability. Take technical ownership of loom reliability — preventive and condition-based maintenance plans, inspection standards and maintenance intervals; diagnose and correct complex mechanical faults in shuttle systems, heddles and belts, cams, drives, bearings, cutters, tape guides, creel and take-up systems.

• Shaft alignment and rotating-part balancing. Align main shafts and drive lines and balance rotating parts to OEM specification, to control vibration and bearing life.

• Wear-parts and spare-parts strategy. Define wear parts (shuttle wheels, heddle belts, tape guides, cutters, bearings), set minimum stock levels and life cycle replacement plans, and keep failure history and downtime analysis.

• Material and R&D process development. Qualify high-tenacity HDPE/PE slit tapes for weaving — friction, elongation, stiffness, static behavior and handling — plan and lead weaving trials, and translate trial results into repeatable production settings and work instructions.

• Mechanical part and system development. Design improved parts and sub-systems for the loom and its feeding system, produce and edit 2D drawings and simple 3D models in CAD, and qualify them on the machine.

• Systematic troubleshooting and documentation. Trace fabric defects and machine faults to root cause and implement corrective and preventive actions — not repeated adjustments; build SOPs, setup sheets and troubleshooting guides in English and Bahasa Indonesia..

• Basic electrical. Coordinate electrical and control-system fault-finding on motors, inverters, sensors and wiring, and define the fault information needed before escalation to the electronics engineer or OEM.

• K3 ownership. Own K3 on the loom floor end to end — risk assessment, machine guarding, isolation and lockout/tagout before every intervention — and make safe practice the norm for every technician.

• Technical training. Coach technicians and operators on the job, assess task competency and keep machine-setting and maintenance practice consistent across shifts.

Tool experiences we expect

• Creel and bobbin system.

• Basic measuring tools: caliper, micrometer, tension gauge, dial indicator.

• Multimeter and basic electrical tools.

• Basic hand tools and power tools.

• Torque wrench, bearing puller and alignment tools.

• Installation and lifting equipment.

• Machine log automation system (machine logs, downtime and settings records).

• CAD system (2D drawings and simple 3D models).

• Wiring diagram and single-line diagram (reading, and marking up as-built).

What we look for

• 5 years and above hands-on with circular looms and tape weaving — woven sack, FIBC or tarpaulin plant — across several fabric specifications; 10 or more years is strongly preferred.

• A track record as a senior mechanic, lead technician or technical specialist, with 3 or more years guiding other technicians and establishing maintenance or operating standards — through technical authority, not a manager's title.

• Hands-on mastery of the tool experiences listed above — you measure, align, balance, troubleshoot and document your own work.

• Experience with recognizedr loom brands — Starlinger, Lohia, Yongming, Hengli, W&H or comparable equipment — ideally including high shuttle-count configurations (8+).

• A systematic mind for troubleshooting: you change one thing, you record it, you prove the cause.

• Comfort with basic electrical work and with full K3 responsibility on the machine floor.

• Bahasa Indonesia fluent; working technical English (OEM manuals, international engineers) is an advantage.

Nice to have

• Experience on HDPE/PE slit tape, not only PP — different friction, stretch and static behavior; strong PP experience is acceptable if you can show you adapted processes to new tape characteristics.

• Experience adapting a loom to non-standard tape specifications in an R&D setting.

• Experience leading OEM commissioning — installation, acceptance testing and performance validation.

• Experience writing SOPs and training material for a mixed-language team.

• Comfort within AI-native workplaces and automated machine-log systems.

• Work history in more than one country or with multi-site international teams.

Why join us

• Direct technical ownership of the weaving line, with no layers between you and the decision.

• A senior technical team from aerospace and advanced manufacturing — and the mandate to build the loom team around you.

• In-house prototype machine shop: days, not months, from drawing to part.

• Novel R&D on high-performance woven materials, not commodity sack weaving.

• Competitive compensation at senior level, health coverage, and Batam — 45 minutes from Singapore.

To apply

Send your CV with the circular loom brands and models you have operated or maintained and your years on each, plus a short description of one or two setup, tuning or defect-elimination programmes you led — the fabric specification, what the machine would not do, what you changed, and what the fabric told you afterwards. Applications without a specific machine example are unlikely to progress. Simple language conveys deep understanding.
