Original job description

Sierra Space Careers:

At Sierra Space, we build the missions and systems that keep our world secure in the domain above Earth.

Sierra Space team members share a spirit of innovation and collaboration and a belief that we can deliver on the boldest missions in space today. Together with our customers, we aim to safeguard our nation, sustain human presence in space, and secure the freedom of operations in low Earth orbit and beyond.

Our success is measured by the trust of those who rely on what we build and deliver, and our technologies keep the United States and its allies mission-ready throughout space.

We are mission-driven, and together, we are an extraordinary team.

About the Role The entry-level Mechanical Engineer I role focuses on supporting senior engineers in various projects related to mechanical systems, propulsion, structures, or environmental systems. The position involves assisting in the analysis, design, and evaluation of mechanical systems and components, collecting and analyzing data, and preparing technical documentation and reports. The role requires clear communication skills, the ability to follow instructions effectively, and a collaborative approach to achieving project goals and meeting deadlines.

In this role, you will assist senior engineers in the analysis, design, and evaluation of mechanical systems and components. You will collect and analyze data related to mechanical systems, propulsion, structures, structural analysis, or environmental systems to support engineering objectives. Additionally, you will contribute to the resolution of routine technical problems of limited scope and complexity. Preparing technical documentation and reports to communicate findings and support project objectives will be a key part of your responsibilities. You will work effectively within cross-functional teams to achieve project goals and meet deadlines, while clearly communicating technical concepts and information both verbally and in writing to ensure alignment and collaboration. About You Our mission is driven by an unyielding commitment to advancing space-based technology in service of our customers and safeguarding national security. We seek individuals who are passionate about innovating beyond boundaries and relentlessly pursuing solutions that protect, preserve and empower – to join us in this critical mission.

We’re looking for team members who align with our values, mission and goals – while also meeting the minimum qualifications below. The preferred qualifications are a bonus, not a requirement.

Minimum Qualifications:

Requires Bachelor's degree in a related field (or equivalent work experience in lieu of degree).
Typically entry-level 0 - 2 years of experience.
Basic understanding of Mechanical Engineering technical principles, standards, theories, and concepts.
Basic application and use of technical principles, standards, theories, and concepts.
Ability to help develop solutions to routine technical problems of limited scope and complexity.
Ability to work in a team and follow guidance from senior engineers.
Clear verbal and written communication of technical concepts and information.

Preferred Qualifications:

Internship or co-op experience in a mechanical engineering or related environment.
Familiarity with design, analysis, and test methods related to mechanical systems, propulsion, structures, and/or environmental systems.
Familiarity with engineering CAD tools such as NX, SolidWorks, or similar including a familiarity with detail drawing standards and GD&T.
Strong problem-solving skills and attention to detail.
Eagerness to learn and develop new skills in a collaborative and dynamic work environment.
Familiarity with manufacturing processes, material sciences, and their impact on mechanical systems.
Previous enrollment in the Sierra Space Internship Program

Compensation:

Pay Range:

$77,234.00 - $106,196.75 Your actual base compensation will be determined on a case-by-case basis and may vary based on job-related knowledge and skills, education, experience, internal equity and market competitiveness.

Elevate Your Career At Sierra Space, we are committed to your personal and professional development. We empower you to make profound and meaningful contributions and foster a vibrant culture of collaboration, where teamwork ignites breakthrough innovations.

We also offer a generous benefit package, including medical, dental, and vision plans, 401(k) with 150% match up to 6%, life insurance, 3 weeks paid time off, and more.

Sierra Space is an industry-leading space and defense technology company providing satellites, spacecraft, and enabling mission systems and components. We deliver mission-proven technologies to our customers that safeguard our nation, protect space-based assets and enable space exploration.

Application Deadline: This role will remain posted until a qualified pool of candidates is identified.

Any unsolicited resumes submitted to our website or to Sierra Space team members not through our approved vendor list or Talent Acquisition will be considered property of Sierra Space, and we will not be obligated to pay any referral fees.
