Principal Process Engineer: ALD Deposition and Scale-Up

Amphiform; United States; On-site; USD 120,000 - 160,000; Full time

Job summary

Amphiform (amphiform.com) is building next-gen energy materials for AI data centres, defence and space: light, abundant and powerful. We achieve that by creating a new type of matter: hybrid materials, built atomic layer by atomic layer, where every atom has a pre-programmed purpose.

You’ll own the path from a recipe that works once to a process that runs consistently, taking ALD/MLD into high-aspect-ratio, non‑planar structures and defining in-spec criteria with metrology and process control to

Qualifications

• Owned an ALD deposition module and progressed it to production.
• Experience with process windows, uniformity, defect reduction, and yield learning on real tools.
• Experience specifying, qualifying, or modifying deposition hardware.

Responsibilities

• Take ALD and MLD processes from lab demo to repeatable manufacture, optimizing cycle time and saturation windows.
• Define in-spec criteria for films and build metrology and process control to maintain it.
• Own reactor qualification, tool matching, and maintenance strategy as capacity grows.
• Improve throughput and cost via better precursor utilization and cycle time.
• Collaborate with reactor vendors on tool specifications and modifications.

Job description

Amphiform (amphiform.com) is building next-gen energy materials for AI data centres, defence and space: light, abundant and powerful. We achieve that by creating a new type of matter: hybrid materials, built atomic layer by atomic layer, where every atom has a pre-programmed purpose.

We just closed a $5.5M pre-seed led by General Catalyst and Main Object, with Thomas Wolf (Hugging Face), Charlie Songhurst, and others.

We just closed a $5.5M pre-seed led by General Catalyst and Main Object, with Thomas Wolf (Hugging Face), Charlie Songhurst, and others.

About the role

You’ll own the path from a recipe that works once to a process that runs consistently, taking ALD/MLD into high-aspect-ratio, non‑planar structures.

What you’ll do

• Take ALD and MLD processes from lab demonstration to repeatable manufacture: saturation windows, uniformity, defectivity, cycle time
• Define what "in spec" means for our films, and build the metrology and process control to hold it
• Own reactor qualification, tool matching, and maintenance strategy as we add capacity
• Throughput and cost directly: cycle time, precursor utilisation, cost
• Work with reactor vendors on tool specification and modification
• Work with our reactor team on tool specification and production

What we’re looking for

• You’ve owned an ALD deposition module and carried it through a production ramp. Module development engineer, thin film development engineer, or process development engineer.
• Experience with process windows, uniformity control, defect reduction and yield learning on real tools
• Experience specifying, qualifying, or modifying deposition hardware

Nice to have

• Conformal deposition into high-aspect-ratio or non‑planar geometries
• Time at an equipment maker, a national lab or a chip manufacturer
• Catalysis or electrochemistry exposure
