Mechanical Engineer

About Redtree

Redtree Engineering specializes in engineering, project management, and construction support services across mission-critical facilities, power systems, industrial projects, and complex infrastructure. Redtree offers 100% remote work for this role. As a growing engineering firm, we've built our team around flexibility from day one, giving engineers the ability to do serious, high-impact power generation design work from anywhere in the U.S., without relocating or commuting to an office.

Position Summary

Redtree is seeking a Mechanical Engineer to support front-end planning, detailed design, and construction administration for power generation projects, with a focus on coal and natural gas-fired power plants, as well as associated balance of plant systems. This role covers the full engineering lifecycle, from front-end planning and preliminary design through final design, construction administration, and startup, and will work closely with multidisciplinary teams (electrical, civil, structural, PM/CM), equipment suppliers, and clients on both new-build and plant modernization/uprate projects.

This is an opportunity to join a fast-growing engineering firm with the technical depth of an established AEC group and the agility of a startup, offering broad exposure across sectors rather than a narrow, single-client scope.

You Will...

• Perform front-end planning, preliminary design, code analysis and detailed design for mechanical systems at coal and natural gas fired generation facilities and associated balance of plant systems.

• Design and size mechanical equipment and piping systems, including pumps, blowers, tanks, and vessels, along with hydraulic calculations and valve/pipe material selection.

• Develop and review P&IDs for pumps, vessels, and tanks.

• Support air quality control systems and effluent limitation guideline (ELG) management for generation facilities.

• Prepare final design packages, including bidding documents and specifications, for compliance with applicable mechanical and building codes, industry standards, and client specifications.

• Manage teams of mechanical engineers to complete assigned activities.

• Coordinate with electrical, civil, structural, and project management teams to ensure integrated, constructible designs.

• Provide construction administration, field engineering, and startup support, including review of compliance submittals and resolution of construction issues (if/when needed).

• Support proposal development, scoping, and schedule estimation for new project pursuits.

• Contribute to project documentation, drawing sets, and technical specifications throughout the project lifecycle (feasibility, preliminary engineering, detailed design, PM/CM, startup/commissioning).

• As applicable to seniority level, mentor junior engineers and/or manage mechanical scope on assigned projects, including development-support and owner's-engineer work such as technical due diligence and design reviews.

If You have...

• Bachelor of Science in Mechanical Engineering or related field from an ABET-accredited program.

• Experience with mechanical design for power generation facilities: combined cycle

• Working knowledge of hydraulic calculations, pump/piping selection and sizing, and valve and pipe material selection.

• Familiarity with P&ID development and mechanical equipment condition assessment.

• Understanding of relevant mechanical, and environmental/air quality codes and industry standards.

• Strong communication skills and ability to coordinate across multidisciplinary project teams.

• Willingness to travel to project/construction sites as needed (estimated to be 10-20%).

Preferred Qualifications

• Professional Engineer (PE) license, or active pursuit of licensure.

• Experience with mechanical design for power generation facilities: coal, natural gas, gas-fired, combined cycle, or similar thermal plants.

• Experience with plant modernization, life extension, or uprate projects in addition to new-build work.

• Experience in EPC or EPCM project delivery environments.

• Exposure to development-support, owner's-engineer, or conceptual design work for conventional power projects.

• Experience with lifecycle cost analysis and mechanical equipment condition assessment.

What Redtree Offers

• 100% remote work, U.S.-based, with no relocation or office requirement.

• 100% employer-sponsored benefits.

• Direct exposure to the full project lifecycle, from concept through construction and commissioning, rather than a narrow phase or discipline silo.

• A growing, entrepreneurial engineering team partnering with industry-leading clients on mission-critical facilities, power systems, and complex infrastructure.

• Multiple openings across Mid to Senior levels, with the flexibility to match title and compensation to the selected candidate's experience.

Work Authorization: Must be able to work in the United States without employer sponsorship, now or in the future.
