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

About the Role

We're hiring a senior mechanical engineer who has delivered power generation and gas-to-power projects at a top EPC, PMC, owner-operator, or equipment OEM. This includes 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. This is a hands-on role where you'll perform real mechanical engineering, quality-check automated outputs, and shape the product's future direction.

Responsibilities

• Perform real mechanical engineering on FEL-2 and early-phase delivery work, owning the parts our software can't handle yet to ensure projects ship.
• Act as the quality gate for Candid's automated mechanical outputs: identify errors before client delivery and provide feedback to improve the product.
• Define how equipment scope is developed and validated through FEED on power and gas-to-power projects, establishing standards for "good."
• Review and validate mechanical content across equipment datasheets, vendor packages, and discipline handoffs.
• Build repeatable checks to catch scope gaps and inconsistencies early in the process.
• Map where mechanical rework occurs, analyze root causes, and identify key inputs driving it.
• Clarify interface points with Process, Piping, I&C, and Electrical disciplines.
• Distinguish between genuinely repetitive tasks and those requiring engineering judgment to guide software automation.
• Help define checks, workflows, and product requirements to enable software to handle repetitive tasks while keeping engineers in control.

Requirements

• 7+ years of experience at a large-scale EPC, PMC, owner-operator, or OEM, primarily focused on power generation or gas-to-power projects.
• Direct experience on combined cycle, simple cycle, gas-to-power, LNG, or cogeneration projects (not refining or petrochem only).
• Owned mechanical equipment datasheet development and vendor package review through FEED.
• Strong expertise in rotating and power-plant equipment: gas turbines, steam turbines, HRSGs, pumps, compressors, fans, and balance of plant mechanical systems (cooling systems, fuel gas conditioning, water treatment).
• Hands-on experience with equipment specification to API and ASME standards (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).
• Ability to quickly spot inconsistencies across datasheets, P&IDs, and vendor packages.
• Clear understanding of cross-discipline dependencies.
• Frustration with big-company processes and a desire for autonomy.
• Comfortable with ambiguity, wearing multiple hats, and a bias toward action over perfection.

Nice to Have

• Discipline lead or technical authority experience.
• Work on data center or behind-the-meter power campuses.
• Experience taking equipment from FEED into procurement and detailed engineering.
• Expertise in packaged or modular systems and skid integration.
• Genuine interest in AI and automation.

Who Thrives Here

You've outgrown the big-firm machine. You're tired of slow approval chains and seeing good work stall in stage gates. You want to own your scope end-to-end, see your work ship, and have a direct line to founders and product teams instead of navigating a 12-person approval chain. At Candid, you'll wear several hats, and there's no rigid playbook—if that sounds like freedom, you'll thrive here. If it sounds like chaos, it may not be the right fit.

Benefits

• Meaningful base salary + equity.
• Unlimited PTO with an emphasis on work-life balance.
• Comprehensive health insurance covering medical, dental, and vision.
• Up to $150/month health and wellness reimbursement (gym, fitness classes, etc.).

Pay

Compensation range: $100K - $250K.
