Journeyman Ironworker - Structural Steel & Metal Building Installer
LOCATION: Watertown, SD
COMPANY: Sentry
Help Build the Backbone of Every Project
At Sentry, we're more than a construction company-we're a full-service EPC team that self-performs across the board. From structural steel and pre-engineered metal buildings to concrete, electrical, and mechanical, our work is complex, fast-paced, and grounded in real results.
As a Journeyman Ironworker, you'll play a critical role in the success of every vertical build we take on. This isn't an entry-level role-it's for someone with grit, technical skill, and a proven track record of safety and reliability. You'll be expected to work independently or lead apprentices with a focus on three non-negotiables: Safety, Quality, and Efficiency.
What You'll Be Doing
You'll be responsible for erecting structural steel frames, connecting beams and columns, and making sure every bolt-up, weld, and lift is done right the first time. You'll work closely with foremen, project managers, and crane operators to deliver safe, efficient, and high-quality installations.
• Key Responsibilities:
• Read and interpret blueprints and detailed erection plans
• Bolt-up, weld, and secure structural members with precision
• Rig, hoist, and place steel using cranes, forklifts, chain falls, come-a-longs, and other heavy equipment
• Ensure structures are plumb, square, and aligned before sheeting or decking begins
• Unload, shake out, and stack prefabricated steel using correct rigging procedures
• Lead or support apprentices while maintaining productivity and safety standards
• Erect and dismantle steel frames, place machinery, install deck, stairs, and guardrails
• Operate lifts and equipment including scissor lifts, boom lifts, and forklifts
• Install insulation, wall panels, and standing seam roofing systems on PEMBs
• Perform welding, torch cutting, grinding, and metal bending as needed
• Maintain clean, organized, and hazard-free work zones at all times
• Follow rigging standards, crane signaling, and OSHA-compliant safety protocols
What We're Looking For
This role is for an experienced tradesperson-someone who takes pride in their craft and doesn't cut corners. If you're a high-performing ironworker who thrives in a fast-paced, hands-on environment and wants to be part of a team that builds things that last, we want to hear from you.
• Minimum Qualifications:
• 4-5+ years of experience as an ironworker, including formal apprenticeship completion
• Proficient in structural steel erection, rigging, and blueprint reading
• Hands-on experience with welding equipment, grinders, shears, and layout tools
• Familiarity with pre-engineered metal buildings and structural steel frames
• Ability to lead small teams or apprentices and maintain productivity standards
• Physically fit and able to lift 60+ lbs, climb, bend, kneel, and work at heights
• 3G and 4G welding certifications preferred-or willingness to obtain
• Comfortable working outdoors in all weather conditions
• High regard for safety, communication, and craftsmanship
