Skilled trades job openings are at a 10-year high across all industries, according to a list of top opportunities in skilled trades vocations released by Aerotek. The report came in advance of Manufacturing Day, which is tomorrow.

The demand for skilled professionals continues to rise every year as traditional tradesmen and tradeswomen retire and fewer millennials come into the trade field, according to Sara Staggs, director of divisional operations for Aerotek’s commercial division.

“Skilled trades professions are the backbone of manufacturing,” Staggs said. “Finding talent is still one of the largest challenges for manufacturing today. At Aerotek, we are looking to help fill the talent gap through collaboration with technical schools, recruiting diverse talent and partnering with apprenticeship programs.”

The top opportunities in skilled trades vocations across all industries, according to Aerotek, include:

• Electrician: 41,000 monthly hires; 5% projected job growth by 2020
• Industrial mechanic: 14,000 monthly hires; 7% projected job growth by 2020
• Machinist: 15,000 monthly hires; 4% projected job growth by 2020
• Maintenance: 80,000 monthly hires; 4% projected job growth by 2020
