Senior Piping Engineer; Preconstruction

What We’re Building

Candid is building the AI layer for EPCs. We use AI to reduce the manual effort behind preconstruction engineering by automating document understanding, consistency checks, and repetitive workflow steps across major disciplines. Our goal is to make preconstruction 10x faster without sacrificing engineering quality.

We recently raised $6.5M from top AI and industrial investors (including Schneider Electric and Meta’s Chief AI Scientist). Our team includes engineers from MIT, Carnegie Mellon, major LNG and power projects, and leading EPCs.

We’re hiring a senior piping engineer who has actually delivered power generation and gas-to-power projects at a top EPC, PMC, or owner-operator. Think combined cycle, simple cycle and peakers, gas-to-power for data centers and behind-the-meter campuses, LNG, and cogeneration, with the high‑energy steam cycle and balance of plant piping that goes with them. If your career has been refining or petrochem process piping with no power work, this isn’t the right fit.

This is a hands‑on role. You’ll do real piping engineering on our delivery work for the parts our software can’t handle yet, you’ll be the quality check on what the software does produce, and you’ll shape where the product goes next. Three jobs in one, and the mix shifts as the product gets better.

• Do real piping engineering on our FEL‑2 and early‑phase delivery work, owning the parts our software can’t handle yet so projects ship
• Be the quality gate on Candid’s automated piping outputs: catch what’s wrong before it reaches a client, and feed it back so the product gets sharper
• Define how piping information gets developed and validated through FEED and early detailed design on power and gas‑to‑power projects, and what “good” looks like
• Review and validate piping content across P&IDs, line lists, piping specs, and tie‑in lists
• Build repeatable checks that catch tagging, completeness, and consistency issues early
• Map where piping rework happens, why it happens, and what inputs drive it
• Clarify interface points with Process, Mechanical, I&C, Electrical, and Civil/Structural (pipe racks and supports)
• Separate the steps that are genuinely repetitive from the ones that need real engineering judgment

• 7+ years at a large‑scale EPC, PMC, or owner‑operator, with most of it on power generation or gas‑to‑power
• Direct experience on combined cycle, simple cycle, gas‑to‑power, LNG, or cogeneration projects (not refining or petrochem only)
• You’ve personally owned line list and piping spec development through FEED
• Strong on power plant piping: high‑energy steam cycle (main steam, hot and cold reheat, feedwater), plus fuel gas, condensate, cooling water, and balance of plant piping
• Hands‑on with ASME B31.1 (power piping) and B31.3 (process piping)
• Familiarity with pipe stress analysis and stress‑critical line identification (CAESAR II or similar)
• Experience with plot plan and 3D model‑driven layout (AVEVA E3D / PDMS, Smart Plant 3D, or similar)
• You spot inconsistencies across P&IDs, line lists, and vendor packages fast
• Clear understanding of cross‑discipline dependencies
• You’ve felt boxed in by big‑company process and you want out
• Comfortable with ambiguity and wearing multiple hats; bias to action over waiting for perfect

• Discipline lead or technical authority experience
• Work on data center or behind‑the‑meter power campuses
• High‑energy piping materials and metallurgy (P91, P22 chrome‑moly), or pipe support and spring hanger design
• Brownfield tie‑ins and constructability constraints
• Real interest in AI and automation

You’ve outgrown the big‑firm machine. You’re tired of waiting three weeks for a markup to clear four layers of review, and tired of watching good work die in a stage gate. You want to own your scope end to end, see what you build actually ship, and have a direct line to the founders and the product instead of a twelve‑person approval chain.

At Candid you’ll wear several hats and there’s no playbook handing you a defined lane. If that sounds like freedom, you’ll love it here. If it sounds like chaos, you won’t, and that’s okay.

• Meaningful base + equity
• Unlimited PTO. Great work needs recharging.
• Health insurance covering medical, dental, and vision
• Up to $150/mo health and wellness reimbursement (gym, fitness classes, and similar)

Compensation Range: $100K - $250K
