Astro Mechanical is a 65-year-old mechanical contracting company rooted in quality craftsmanship, strong relationships, and a family-style environment where everyone supports one another and wears a few hats when needed. We specialize in commercial, industrial, and government-funded projects, including schools, public buildings, and infrastructure work.

We’re looking for an Estimating Coordinator to join our tight-knit team.  This is a full-time, on-site position working in our El Cajon, CA office. This role will primarily support the estimating department—working directly with our Estimator to prepare bids, coordinate subcontractors, and manage proposal documentation.

  • Prepare final bid packages and support proposal submissions.

Project Startup & Limited Coordination (Secondary Support)

  • Prepare and track pre-construction RFIs and submittals during project handoff.
  • Review submittals for compliance with project specifications before forwarding for approval.
  • Maintain a detailed submittal log to ensure timely submissions and avoid construction delays.
  • Support with change order logs, cost tracking, and documentation as needed.
  • Assist with O&M manuals, warranties, final submittals, and closeout deliverables.

    • What You Bring

  • Required : Plumbing and / or pipefitting experience (field or estimating).
  • 2+ years in estimating, project coordination, or APM role (mechanical preferred).
  • Experience with government (NAVFAC / federal) and commercial projects a plus.
  • Project HQ (or similar), Bluebeam, and MS Office proficiency.
  • Highly organized, detail-driven, and comfortable with bid deadlines.
  • Strong communication skills and a collaborative, roll-up-your-sleeves attitude.

    • What We Offer

  • Salary range : $65,000 – $85,000 (DOE)
  • Medical, dental, and vision insurance
  • 401(k) with company match
  • PTO and paid holidays
  • A diverse mix of projects—federal, commercial, and industrial
  • Growth path in estimating
  • A tight-knit, family-style culture where your impact is seen and valued
