How much do junior mechanical engineering jobs pay per year?

As of Aug 7, 2026, the average yearly pay for junior mechanical engineering in the United States is $73,142.00, according to ZipRecruiter salary data. Most workers in this role earn between $63,500.00 and $82,500.00 per year, depending on experience, location, and employer.

What types of projects do junior mechanical engineers typically work on, and how much autonomy can I expect in this role?

As a Junior Mechanical Engineer, you will often be involved in supporting senior engineers with tasks such as drafting designs, conducting simulations, preparing technical documentation, and performing tests on prototypes. Early in your career, you'll typically work within a multidisciplinary team, collaborating with experienced engineers and other departments such as manufacturing and quality assurance. While you may start with closely supervised assignments, many organizations encourage gradual independence as you demonstrate your skills and reliability. Over time, you will likely take on more complex project components and gain opportunities to lead smaller tasks or initiatives.

What are the key skills and qualifications needed to thrive as a junior mechanical engineer?

To thrive as a Junior Mechanical Engineer, you need a solid understanding of mechanical engineering principles, a relevant engineering degree, and foundational knowledge of design and manufacturing processes. Familiarity with CAD software (such as SolidWorks or AutoCAD), simulation tools, and basic project management systems is typically required. Strong problem-solving abilities, attention to detail, and effective teamwork and communication skills help you excel in cross-functional environments. These skills are crucial for delivering accurate designs, collaborating efficiently, and supporting successful project outcomes in engineering teams.

What is the difference between Junior Mechanical Engineering vs Mechanical Design Engineer?

AspectJunior Mechanical EngineeringMechanical Design Engineer
Required CredentialsBachelor's in Mechanical Engineering or related fieldBachelor's or higher in Mechanical Engineering or Design
Work EnvironmentEntry-level, team-based projects, manufacturing or R&D settingsDesign-focused tasks, CAD software, product development teams
Employer & Industry UsageManufacturing, automotive, aerospace, HVACProduct design, engineering firms, industrial equipment

Junior Mechanical Engineers typically perform basic engineering tasks under supervision, focusing on learning and supporting projects. Mechanical Design Engineers concentrate on creating and refining product designs using CAD tools, often requiring more specialized design skills. While both roles require a mechanical engineering background, the Design Engineer role emphasizes design and development, whereas the Junior Mechanical Engineer role is more about supporting engineering processes and gaining experience.

What does a junior mechanical engineer do?

A Junior Mechanical Engineer assists in designing, developing, and testing mechanical devices and systems under the supervision of senior engineers. Their responsibilities often include creating technical drawings, performing basic calculations, supporting prototype development, and helping to solve engineering problems. They also collaborate with other team members to ensure projects meet specifications and deadlines. This role typically serves as an entry-level position, providing valuable hands-on experience and professional development within the mechanical engineering field.

Job description

Mechanical Engineer (TS/SCI Required)
Leidos is seeking a motivated Mechanical Engineer to support critical national security missions in Reston, Virginia. This role focuses on the assessment, reverse engineering, and characterization of complex above-ground and subterranean facilities located in denied-access environments.
The successful candidate will apply mechanical engineering principles to analyze facility designs, spatial layouts, operational workflows, and supporting infrastructure to determine functional capabilities and mission relevance. You will evaluate facility systems, model critical infrastructure, identify vulnerabilities, and contribute technical insights that support complex intelligence and defense initiatives.
This position is ideal for an engineer who enjoys solving challenging problems in situations where complete information is rarely available. The ideal candidate combines curiosity, analytical thinking, and engineering rigor with exceptional attention to detail. Working alongside experienced engineers, analysts, and government personnel, you will contribute to mission-critical assessments in a fast-paced, collaborative environment.
Primary Responsibilities
Reverse Engineering & Facility Characterization
Analyze and characterize the physical and functional attributes of facility layouts, building architecture, and operational workflows within denied-access environments to determine facility purpose, capability, and operational capacity.
Vulnerability Assessments
Evaluate facility and infrastructure designs to identify security vulnerabilities, single points of failure, operational bottlenecks, and potential mission impacts.
3D Modeling & Simulation
Develop high-fidelity 3D models and conduct engineering simulations to replicate facility operations, workflow efficiencies, and structural or mechanical limitations.
Infrastructure Analysis
Apply multidisciplinary engineering knowledge to assess supporting facility systems, with a primary focus on Mechanical, Electrical, and Plumbing (MEP) integration and functionality.
Technical Documentation & Reporting
Translate field-collected data, intelligence information, and engineering assessments into comprehensive technical reports, CAD/BIM products, and simulation-based analyses for Department of Defense stakeholders.
Research & Development
Support customer-approved research and development initiatives independently or as part of a multidisciplinary team to advance analytical methodologies, modeling capabilities, and mission solutions.
Required Qualifications
  • Active and in scope TS/SCI clearance and willingness to obtain a polygraph required. Must be a U.S. Citizen.
  • Working knowledge of engineering principles, theories, concepts, and techniques, with the ability to apply them to technical and mission-focused challenges.
  • Bachelor's degree with 2+ years of relevant experience, or a Master's degree with less than 2 years of relevant experience.
  • Relevant experience includes facility analysis, infrastructure vulnerability assessments, and mechanical engineering within commercial, Department of Defense, or Intelligence Community environments.
  • MEP Systems Knowledge: Understanding of Mechanical, Electrical, and Plumbing (MEP) system design, integration, and operational functionality within complex industrial or military facilities, including specialized containment systems, filtration systems, and backup power infrastructure.
  • Ability to identify industrial HVAC equipment, estimate system size and capacity, and assess operational capabilities through visual analysis.
  • Ability to evaluate, organize, and utilize large datasets from diverse sources, including field-collected data, equipment technical manuals, and existing facility models.
  • Experience with 3D modeling, engineering analysis, and physical simulation methodologies.
  • Familiarity with interpreting engineering drawings, facility layouts, blueprints, and intelligence-derived technical data.
  • Ability to make sound technical judgments with incomplete information and clearly communicate assumptions, information gaps, and recommended paths forward.

Preferred Qualifications
  • Two or more years of field experience working with industrial HVAC systems, including air-cooled and water-cooled chillers, condensers, cooling towers, air handlers, heat exchangers, boilers, and related equipment.
  • Working knowledge of air management systems supporting critical environments, including medical laboratories, clean rooms, chemical laboratories, and similar specialized facilities.
  • Hands-on experience with advanced Building Information Modeling (BIM) and engineering simulation tools, including Autodesk Revit, VENTSIM, ETAP, and other industry-standard CAD and modeling platforms.
  • Experience supporting forensic engineering investigations, industrial accident analyses, or Department of Defense facility vulnerability studies.
  • Professional Engineer (PE) license and/or Project Management Professional (PMP) certification.
  • Experience identifying mechanical system vulnerabilities and developing effective corrective actions.
