Martin Human Resource Services logo

Martin Human Resource Services

Martin Human Resource Services is a Calgary-based specialist recruiting firm dedicated to connecting Heavy Duty (HD) Mechanics and related technical talent with employers across Canada in the mining (underground and open pit), civil construction, and oil and gas service industries. With more than 30 years of focused experience, the firm has deep roots in key Canadian hubs, including Timmins ON, Red Deer AB, Central and Southern Nova Scotia, and North Eastern BC, enabling extensive reach into both active and hard-to-find passive talent pools. Their candidate network is built and continuously expanded through relentless industry networking, a steadily growing base of first-level LinkedIn connections, and a proprietary resume bank established over decades of sector involvement. Operating on a streamlined, contingency-based model, Martin HR charges no fees unless a client hires a referred candidate, offers a simple low flat placement fee, and backs every hire with a clear 90-day guarantee that includes either a no-cost replacement within 30 days or a 75% fee reimbursement. The firm’s process minimizes employer effort and advertising costs: clients share a job description or ad, Martin HR conducts direct email outreach to targeted candidates, completes telephone interviews with interested professionals, shortlists those with the required education and solid work record, and forwards qualified resumes for selection. A distinctive non-poaching policy—never recruiting from current or former clients—underscores long-term partnership values, while services can be paused or terminated easily via email or phone. For job seekers, the firm maintains an “internal” model, rarely posting to external job boards; applicants submit their resume and email to join the contact list, receive direct email notifications about matching roles, discuss opportunities by phone, and benefit from regular feedback. Typical demand includes HD Mechanics for mining, construction/earthmoving, oil and gas service companies, heavy construction equipment repair shops and dealerships, as well as power generation technicians, with opportunities spanning all provinces and northern territories.
