Job Title: Mechanical Systems Engineer

Job Code: 41934

Job Location: Forest, VA

Job Schedule: 9/80: Employees work 9 out of every 14 days – totaling 80 hours worked, and have every other Friday off

Job Description:

The Shipboard Systems Mechanical Engineer designs, tests, troubleshoots, and implements systems that satisfy specific customer requirements relating to a shipboard environment. These systems include L3Harris and vendor equipment with mechanical, electrical, and computing components that must integrate into an operational system that passes system tests. Since these systems incorporate technology of a sensitive nature, a U.S. citizenship is required. Since a portion of the position is involved with testing and physical manipulation of equipment, minimum personal mobility capabilities are also considered mandatory, (ability to traverse a ladder, lift/carry at least 35 lbs., perform light mechanical modification tasks such as working with hand tools, drills, etc.).

The successful candidate will work closely with experienced engineers who perform these functions now and will assign tasks and provide oversight as experience is gained. The candidate will also have significant exposure to vendors and external customers who purchase shipboard systems as well as the people within L3Harris who participate in these programs, requiring the ability to communicate effectively with a diverse audience. Understanding and adhering to established procedures and documenting results will also be a key skill. Additionally, general computer literacy is necessary for performing many daily tasks and the candidate must be able to travel occasionally. As this person adds to their knowledge of the L3Harris systems, a higher level of accountability, independence, and enthusiasm for branching into new areas will be expected to achieve career growth.

Essential Functions:

The Systems Engineer should have practical hands-on experience with technical systems. Experience in mechanical design and/or testing with a working knowledge of material properties, (geometry, strength, bending/welding etc.) is desired.
Crafting solutions for engineering problems
Growing knowledge in one or more specialty areas and working toward becoming an expert resource
Reporting regularly on project status and progress
Following established company policies and procedures

Qualifications:

Bachelor’s degree in Mechanical Engineering required; a dual degree in Electrical Engineering is preferred and a minimum 4 years of prior relevant experience. (OR) Graduate degree and a minimum of 2 years of prior related experience. In lieu of a degree, a minimum of 8 years of prior related experience.
US Citizen
Ability to obtain Secret Clearance

Preferred Additional Skills:

Able to work within a cross-functional team environment with excellent interpersonal skills. Effective at both verbal and written communication (English). The successful candidate will possess shared L3Harris values of Integrity, Teamwork, Excellence, and Accountability.
3+ years technical experience in mechanical design, mechanical CAD, mechanical testing or related field
Demonstrated ability to manage multiple concurrent project tasks and prioritize them appropriately
Ability to clearly & concisely communicate issues for technical and non-technical audiences
Demonstrate leadership skills which include customer focus, change management, teamwork, diversity, and integrity
Self-motivated team player, able to set priorities and manage to deadlines
Ability to obtain Sec+ Certification

In compliance with pay transparency requirements, the salary range for this role in Virginia is $80,500 to $149,500. This is not a guarantee of compensation or salary, as final offer amount may vary based on factors including but not limited to experience and geographic location. L3Harris also offers a variety of benefits, including health and disability insurance, 401(k) match, flexible spending accounts, EAP, education assistance, parental leave, paid time off, and company-paid holidays. The specific programs and options available to an employee may vary depending on date of hire, schedule type, and the applicability of collective bargaining agreements.
