Provectus uses Precision Photosynthesis to accelerate nature in a proprietary biomanufacturing platform, producing some of the world's most valuable specialty ingredients. Our technology underpins the delivery of Surf'N'Turf, a world-first livestock feed additive that reduces methane emissions by up to 95% while improving farm yields.

Headquartered in Noosa, Australia, our team has built a scalable and sustainable production platform. We are now expanding global operations, bringing Surf'N'Turf to market, and advancing our pipeline of algae-derived products to serve agriculture, consumer, and therapeutic markets.

Position summary

The Assembly Supervisor supervises and coordinates a multi-disciplinary team to assemble, fit-out, test and commission the company's plastic tanks and all related plumbing, mechanical and electrical/instrumentation components. The role ensures safe, high-quality assemblies that meet engineering drawings, SOPs and regulatory/operational requirements; it also ensures robust handovers to commissioning/operations. This will be a hands on position where required.

Key accountabilities & responsibilities

• Supervise and carry out assembly of plastic tanks), including joining methods appropriate to materials (e.g., solvent welding, heat/fusion welding, mechanical fastening, gasketed bolted joints and adhesive bonding).
• Ensure correct installation of tank frames, support structures, seals and fittings to drawing tolerances.
• Implement tank-specific safe work practices (eg. preventing cracking during fill/drain, supporting paired tank operations).
• Supervise/plumb pipework systems feeding and servicing tanks:
• Oversee joining techniques for plastic piping
• Execute and/or direct hydrostatic and leak tests, pressure decay and flow verification to ensure system integrity and correct flow rates.
• Supervise assembly and integration of electrical components and instrumentation
• Ensure wiring, terminations and cable routing meet electrical safety standards and IP/ingress protection requirements; ensure strain relief, correct glands and labelling.
• Implement electrical isolation, lockout/tagout and safe-testing procedures for the team.
• Plan and supervise commissioning sequences: electrical/instrument checks, leak & pressure testing, functional tests of pumps/valves/sensors and full system integration checks.
• Maintain build records, wiring diagrams, as-built drawings, test protocols and sign-offs. Ensure all documentation is complete before handover to commissioning/operations.
• Enforce quality standards, PPE, safe systems of work, and relevant WHS/HSE procedures. Ensure team compliance for working at heights, confined space entry (if relevant), manual handling and lifting equipment.
• Report and investigate incidents and near misses; ensure corrective actions are followed.
• Ensure training and competency records are maintained.
• Lead, schedule and develop the fitout/tank assembly team and subcontractors; coach on best practice for plastic joining, plumbing routing and electrical/instrumentation assembly.
• Drive lean and standard work practices to improve throughput, reduce rework, and standardise assemblies.

Key performance indicators (KPIs)

• On-time completion of tank builds and fitout milestones.
• Leak-free builds and successful commissioning on first pass.
• Zero serious safety incidents; reduction in near misses.
• Electrical and plumbing installations pass safety and functional inspections.
• Reduced rework rates and improved first-pass acceptance.

Essential skills & experience

• Trade qualification or Certificate III (or equivalent) in Mechanical, Plumbing, Fabrication, Instrumentation or related discipline.
• 3–5 years' hands-on experience with plastic tank assembly/plastic joining and plumbing, plus supervisory experience.
• Practical experience with plastic joining techniques (solvent cement, heat/fusion, gasketed joints and mechanical fasteners).
• Proven experience installing and testing pipework, valves, pumps and fluid handling systems.
• Strong leadership, planning, communication and problem-solving skills.
• Good understanding of WHS requirements, lockout/tagout, confined space and lifting-equipment safety.

Desirable / advantageous

• Experience with motor/pump installation and commissioning, VFDs and basic PLC I/O concepts.
• Experience with instrumentation (level/pressure/flow sensors) and functional testing.
• Licences/certificates: forklift, crane/rigging, confined space, working at heights. (Electrical work to be performed by licensed electricians; supervision experience of electrical trades is advantageous.)
• Formal training in supervision/leadership and in Lean manufacturing / standard work.
