Worth knowing: MIT Mechanical Engineering is the structural depth feature most national mechanical engineering surveys understate for MA. MIT's Department of Mechanical Engineering is consistently ranked #1 nationally and produces substantial engineering talent across Boston biotech facility engineering, defense + aerospace, and medical device specialty work. GE Aviation Lynn (~3K employees, ~125-year-old jet engine manufacturing facility — currently produces F-414 fighter engine + commercial CFM engine components) anchors aerospace mechanical engineering in MA with substantial union representation. Boston Scientific HQ Marlborough (Fortune 500 medical device, ~13K MA employees) operates substantial precision mechanical engineering for catheter + stent + implant device design at FDA Class III medical device scale — senior medical device mechanical engineers at Boston Scientific + Abbott + Medtronic MA clear $155-235K TC. Raytheon Technologies Waltham HQ (RTX, Fortune 100 defense, ~14K MA employees) operates substantial missile + radar mechanical engineering. Kendall Square biotech facility mechanical engineering (cleanroom design + cGMP manufacturing facility mechanical + clean utility design for Moderna + Vertex + Biogen towers) drives specialty premium. MA's combined effective rate at $150K senior ME comp is 5% flat — but at $1.117M+ TC the Fair Share Amendment 4% surtax pushes combined top to 9%.
