Micro/Nanofabrication Engineer

Reports to: Principal Engineer

Location: Singapore, on-site (cleanroom)

Type: Full-time

We are an early-stage, venture-backed Singapore deep-tech company building manufacturing technology for photonic interconnects in AI computing. We are assembling a small, senior team to turn a proven laboratory process into a qualified, manufacturable product, working in lab and cleanroom facilities in Singapore.

The role

You will bring up and run our new industrial two-photon lithography (2PL) system and own the direct-write fabrication of precision 3Dmicrostructures for our process tooling. You join at the start, so the tool, its recipes and its lab set-up will be yours.

What you will do

• Install, accept and qualify the 2PL system with the vendor; set up safe-operation procedures; train a second operator.

• Develop writing recipes (dose, objectives, stitching, grayscale and aligned writing) for structures from sub-micrometre features to millimetre-scale parts, including in new, in-house-developed resins.

• Build the fabrication flow: substrate preparation, writing, development, post-cure and surface treatment.

• Measure what you make (white-light interferometry, SEM,AFM) and feed results into design changes, typically on a weekly cycle.

• Track write time, throughput and cost per part; maintain the tool and its records.

What you will bring

• BEng or MSc in engineering, physics, materials science or a related field.

• Hands-on two-photon lithography (direct laser writing)or cleanroom nanofabrication experience.

• Photoresist processing, chemical handling and clean room discipline.

Nice to have

• Grayscale, aligned or large-area stitched writing.

• Soft lithography or replica moulding.

• Python scripting for job automation and data handling.

What success looks like

Within the first months, the tool accepted and running with a second trained operator; by 12 months, repeatable fabrication from documented recipes; by 24 months, a production-ready fabrication process supplying a pilot lot.
