Rotational Project Engineer information

How does the rotational aspect of a Rotational Project Engineer role enhance professional development and career growth?

The rotational structure allows project engineers to gain hands-on experience across multiple departments or project phases, such as design, procurement, construction, and commissioning. This exposure helps develop a broad skill set, fosters cross-functional understanding, and enables you to discover your professional strengths and interests. Employers often use these programs to identify high-potential employees for future leadership roles, making it an excellent pathway for career advancement. Additionally, frequent team changes enhance adaptability and communication skills, both of which are highly valued in engineering management.

What is the difference between Rotational Project Engineer vs Mechanical Project Engineer?

AspectRotational Project EngineerMechanical Project Engineer
CredentialsBachelor's in Mechanical Engineering, relevant certifications (e.g., PMP)Bachelor's in Mechanical Engineering, relevant certifications (e.g., PMP)
Work EnvironmentMultiple project sites, rotating assignments across departmentsProject sites, focused on specific mechanical projects
Industry UsageCommon in manufacturing, energy, and engineering firms with rotational programsWidely used in construction, manufacturing, and engineering projects

The main difference is that a Rotational Project Engineer participates in rotating assignments across different projects or departments, gaining diverse experience. In contrast, a Mechanical Project Engineer typically focuses on managing specific mechanical projects. Both roles require similar credentials but differ in scope and work environment.

What are Rotational Project Engineers?

Rotational Project Engineers are early-career engineering professionals who participate in structured programs that rotate them through different departments, projects, or locations within a company. These rotations provide exposure to various aspects of engineering, such as design, manufacturing, operations, and project management. The goal is to develop a well-rounded skillset, build a broad understanding of the organization, and identify areas of interest for long-term career growth. Rotational Project Engineers often work with mentors and are given increasing responsibility as they progress through the program.

What are the key skills and qualifications needed to thrive as a Rotational Project Engineer, and why are they important?

To thrive as a Rotational Project Engineer, you need a bachelor's degree in engineering, strong analytical abilities, and a solid understanding of project management principles. Familiarity with CAD software, project scheduling tools like MS Project, and possibly certifications such as EIT or PMP is often valued. Strong communication, adaptability, and teamwork skills help you succeed in varied assignments and environments. These competencies ensure you can quickly contribute to diverse projects, learn new systems, and collaborate effectively across departments.

Job description

Join our fast-paced and passionate team as an Optical Engineer 2. As we scale, you will be instrumental in building our foundation from the ground up. This is a dynamic, hands-on role for a self-starter who thrives in a fluid startup environment. You'll have the opportunity to work on cutting edge technologies, work closely with leadership, and develop and implement engineering practices that support our mission and growth. Your key responsibilities are as follows:
  • Work independently and in a team while overcommunicating with the manager, project engineer, and the teammates. Will mentor junior engineers.
  • Execute complex engineering tasks involving planning, preparation, data/information collection, and analysis and decision-making in a process involving peer reviews and documentation of the results.
  • Use tenacity, patience, self-discipline, and passion for excellence to assure accuracy of execution schedule, data quality/integrity, conformance to company best practices, clarity in communication, and documentation.
  • Use every opportunity to grow competency through mentorship, curiosity, communication, exposure, and initiative.

Requirements
  • This position requires access to export-controlled information. Employment is contingent upon the applicant being a U.S. person as defined by 8 U.S.C. § 1324b(a)(3).

Experience:
  • A bachelor's degree in Optical Engineering, Physics, or a related field.
  • Minimum of 2 years of relevant experience, ideally within a startup or technology company.

Skills:
  • In-depth knowledge of various optical engineering topics along with a strong grasp of a standard optical engineering degree curriculum.
  • Comprehensive understanding of optical modeling techniques including ray tracing, wave propagation, and electromagnetic solvers.
  • Insight into laser beam propagation, including how the movement and rotation of optics influence a beam's near-field, far-field, beam quality, and fiber coupling efficiency.
  • Ability to design according to specifications by planning design processes that address a range of innovative requirements, identifying the most efficient analysis methods for each, and developing and validating new design and analysis approaches.
  • Capability to assess optical layouts for optimal performance, manufacturability, and risk evaluation.
  • Familiarity with arranging laser modules within optical design software.
  • Extensive knowledge of how to quantitatively characterize an optic, including its material properties, surface specifications, surface irregularities, roughness, mechanical constraints, coatings, power handling, environmental considerations, testing, and inspection methods.
  • Thorough understanding of tolerance analysis techniques for component fabrication.
  • Knowledge of fiber optics as applied to high-power continuous wave (CW) laser systems, including multi-mode, single-mode, polarization-maintaining, step index, photonic crystal, and endcap variants.
  • Proven ability to successfully complete engineering tasks involving design software (preferably Ansys Zemax OpticStudio, Photon Engineering FRED, and/or Lambda Research OSLO), quantitative analysis/programming tools (such as Python), instrumentation and measurement, part fabrication or procurement, integration and testing, data collection, and documentation.

Startup Mindset:
  • You're creative, flexible, and eager to wear multiple hats.
  • You're passionate about building systems from the ground up and comfortable with ambiguity and change.

Benefits
The expected annual salary range for this position is $100,000-$150,000.
As a full-time employee, you will be eligible for Monarch's comprehensive benefits package, which includes:
  • Medical, Dental, and Vision insurance
  • Fidelity 401(k) plan with 4% employer matching
  • 20 paid time off (PTO) days per year
  • 13 paid company holidays
  • 9/80 work schedule (every other Friday off)
