How to Apply for Senior Laser Engineer

at Limelight Steel

🏢 About Limelight Steel

Limelight Steel is revolutionizing steelmaking by developing clean electric laser furnace technology to dramatically cut industrial CO2 emissions. This company offers the unique opportunity to work on cutting-edge decarbonization technology that could transform one of the world's most carbon-intensive industries, combining environmental impact with technical innovation.

About This Role

As Senior Laser Engineer, you'll lead the build, integration, and commissioning of high-powered fiber coupled semiconductor lasers for Limelight's pilot laser furnace, directly enabling their mission to decarbonize steel production. This role is pivotal in translating theoretical laser technology into practical industrial applications that could revolutionize how steel is made.

💡 A Day in the Life

A typical day might involve hands-on work commissioning laser components in the pilot furnace facility, collaborating with mechanical and electrical engineers on system integration challenges, and developing procedures for laser alignment and safety. You'd likely split time between the lab/facility floor, design reviews for next-generation laser modules, and training technicians on safe operation protocols.

Practice questions for this role

🎯 Who Limelight Steel Is Looking For

  • Has 5+ years hands-on experience specifically with high-power (>1kW) laser system design, build, and commissioning, not just operation or maintenance
  • Demonstrates practical experience with optical design tools like Zemax or CODE V for translating simulations into manufacturable designs
  • Shows proven ability to move quickly from concept to working hardware, particularly with complex optomechanical systems
  • Possesses experience integrating laser systems with cooling, electrical, and control systems in industrial environments

📝 Tips for Applying to Limelight Steel

1

Quantify your high-power laser experience - specify exact power levels you've worked with (e.g., 'designed 5kW fiber laser system for industrial cutting') and the scale of systems you've commissioned

2

Highlight specific experience with optical protection systems and laser safety protocols for industrial environments, not just laboratory settings

3

Include concrete examples of how you've optimized laser beam delivery systems for specific industrial applications, mentioning collimators, lenses, and mirrors you've worked with

4

Demonstrate your understanding of steelmaking processes by mentioning how laser parameters affect iron/steel production, even if indirectly

5

Showcase vendor management experience specifically for laser and optical components, as you'll be working with suppliers for their 100 MW furnace development

✉️ What to Emphasize in Your Cover Letter

['Your direct experience with high-power (>1kW) laser system commissioning and how it applies to industrial furnace applications', 'Specific examples of translating process requirements into laser/optical specifications for industrial systems', 'Your approach to developing laser alignment procedures and safety protocols for industrial environments', 'How your background enables you to work at the intersection of optical engineering, mechanical systems, and industrial controls']

⚠️ Common Mistakes to Avoid

  • Focusing only on academic or research laser experience without demonstrating hands-on industrial commissioning experience
  • Being vague about power levels - saying 'high-power lasers' without specifying you've worked with >1kW systems
  • Failing to show understanding of how laser systems integrate with broader industrial systems (cooling, electrical, controls)
