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.
