Welcome to BlueCore Energy! We are on a relentless mission to democratize access to clean energy. By designing and building advanced floating Pressurized Water Reactors (PWRs) on barges right here in Long Beach, CA, we are bringing scalable, clean, and reliable power to the world. Joining our team means getting in on the ground floor of a revolution in marine small modular reactors (SMRs). If you are passionate, driven, and ready to tackle some of the most exciting challenges of our time, we want you on our team!
Our Values
Humility — We hold strong opinions loosely, say "I don't know," ask for help early, and let the best idea win regardless of who it came from.
Inclusivity — The best engineering comes from many perspectives. We build a team where everyone is heard, and we mean it.
Pragmatism — We solve the real problem in front of us, reuse what already works, and value a tested answer over an elegant one.
You'll turn analysis into hardware. You'll help run experimental testing and use the thermal-hydraulic team's analysis to size components, talk to vendors, and explore the design space. You’ll design test campaigns, create test plans and procedures, run and acquire data from experiments, and turn this knowledge into system-level designs for our production units. You'll build models in NX CAD and generate the drawings needed for components and sub-systems. This is a hands-on, collaborative role with room to grow — a great fit for someone eager to learn, comfortable asking questions, and happy to get their hands dirty in the lab and on the deck plate.
Responsibilities
Help plan and perform experimental testing of components and sub-systems
Use analysis from the thermal-hydraulics team to size components, engage vendors, and explore the design space.
Build and maintain NX CAD models and generate the required drawings for components and sub-systems.
Design with the marine environment in mind — vibration, shock, thermal cycling, corrosion, and tight volumetric constraints aboard a vessel.
Collaborate across nuclear, thermal, and software teams; give and receive feedback openly.
Bachelor's degree in Mechanical Engineering or a related field.
Hands-on experience with CAD (NX preferred; SolidWorks/Creo acceptable) and drawing generation, including GD&T.
Exposure to hardware testing, component sizing, or vendor interaction (internships/projects count).
A pragmatic, curious, low-ego approach to problem-solving.
Experience with FEA or first-principles hand calcs to inform design.
Familiarity with marine, nuclear, aerospace, or other regulated hardware environments.
Experience shepherding a part from design → fab → test → iteration
On-Site Requirement: Our team works together at our Long Beach facility, right next to our barge.
Highly Cross-Functional: Startups move fast! You must possess the ability to seamlessly collaborate across multiple teams to rapidly solve problems and keep production moving.
Physical & Machinery Requirements: Because we are a hands-on startup, this role may require the ability to perform physical labor, navigate active construction/manufacturing zones, and/or operate heavy machinery and specialized manufacturing equipment as needed.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
