Senior Mechanical Engineer (Power Generation / Gas-to-Power)

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. This Role We're hiring a senior mechanical engineer who has actually delivered power generation and gas-to-power projects at a top EPC, PMC, owner-operator, or equipment OEM. Think combined cycle, simple cycle and peakers, gas-to-power for data centers and behind-the-meter campuses, LNG, and cogeneration, with the rotating equipment and balance of plant that goes with them. If your career has been refining or petrochem static equipment with no power work, this isn't the right fit. This is a hands-on role. You'll do real mechanical 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. What You'll Do This is hands-on engineering plus product. Day to day you'll: - Do real mechanical 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 mechanical outputs: catch what's wrong before it reaches a client, and feed it back so the product gets sharper - Define how equipment scope gets developed and validated through FEED on power and gas-to-power projects, and what "good" looks like - Review and validate mechanical content across equipment datasheets, vendor packages, and discipline handoffs - Build repeatable checks that catch scope gaps and inconsistencies early - Map where mechanical rework happens, why it happens, and what inputs drive it - Clarify interface points with Process, Piping, I&C, and Electrical - Separate the steps that are genuinely repetitive from the ones that need real engineering judgment You'll help define the checks, workflows, and product requirements that let software take on the repetitive parts, with engineers in control. What We're Looking For - 7+ years at a large scale EPC, PMC, owner-operator, or OEM, 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 mechanical equipment datasheet development and vendor package review through FEED - Strong on rotating and power-plant equipment: gas turbines, steam turbines, HRSGs, pumps, compressors, fans, and balance of plant mechanical (cooling systems, fuel gas conditioning, water treatment) - Hands-on with equipment specification to API and ASME (API 610, 611, 612, 617; ASME VIII; B31.1 power piping) - Experience coordinating OEM turbine and major equipment packages (GE Vernova, Siemens Energy, Mitsubishi Power, or similar) - You spot inconsistencies across datasheets, P&IDs, 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 Nice to Have - Discipline lead or technical authority experience - Work on data center or behind-the-meter power campuses - Taking equipment from FEED into procurement and detailed engineering - Packaged or modular systems and skid integration - Real interest in AI and automation Who Thrives Here 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
