Senior Mechanical Engineer

About the role

This role accelerates advanced power generation by leading mechanical design and validation. The position guides cross-functional integration and mentors engineers on a team building scalable nuclear energy systems.

Software engineers turn product ideas into working code. Engineers work in small teams, review each other's work, and ship in small batches. Most teams follow agile practices such as sprints and daily standups. Engineers also write tests, fix bugs, and improve performance. The field values clear communication as much as technical skill. Engineers spend part of every week on planning, code review, and debugging, not just writing new code. The ability to explain a technical decision in plain words separates strong engineers from the rest.

Key facts

What you'll do

Mechanical systems for major subsystems are led to align performance targets with manufacturability and cost. Design consistency with company standards and engineering rigor is ensured through mentoring junior engineers and reviewing mechanical concepts. Integration with electrical, manufacturing, and systems engineers is driven to optimize designs and enable production readiness.

Requirements

A Bachelor's degree in Mechanical Engineering or a related field is required. Candidates bring 5+ years of experience in mechanical design and product development. A proven track record of designing and delivering production-ready hardware is expected. Expertise in CAD (SolidWorks, Creo, NX, or similar) and mechanical drafting standards is necessary. Strong knowledge of materials, manufacturing processes, and mechanical systems is required. Experience performing or overseeing FEA and CFD analyses is essential. Clear communication, technical documentation, and leadership skills are required.

Nice to have

A Master's degree in Mechanical Engineering or a related field is preferred. Experience in high-performance or safety-critical systems within aerospace, energy, or defense is valued. Deep understanding of DFM/DFA and reliability engineering is beneficial. Familiarity with PLM/PDM tools and design control processes is helpful. Hands-on prototyping, testing, and validation experience is advantageous. Strong analytical capability supports leading root cause investigations.

Practical notes

Free daily lunch and dinner are provided onsite. Typical interview steps

Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.

Good to know

The role involves advanced mechanical systems for energy applications. The team uses CAD and analysis tools to guide design decisions. High-temperature nuclear power development defines the technical context. Rapid growth offers opportunities for ownership and impact. Collaboration with experienced engineers and operators shapes day-to-day work.

Questions to ask

Good questions to ask the employer in the interview: what does success look like in the first six months, how is the team structured, what is the current biggest challenge, and how are decisions made. Asking about growth paths and the review process is also well received. Employers expect questions, and good ones show preparation.

Career growth

Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
