## Job description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

## ABOUT THE ROLE:

The Power Generation Engineering team is seeking a talented Fluids Engineer where you will have the opportunity to utilize your knowledge, experience, and creativity to rapidly design, build, and activate fluid systems supporting power plants and related generation infrastructure.

## RESPONSIBILITIES:

- Design, build, and activate fluid systems for power generation plants, including fuel gas, ammonia, water, compressed/instrument air, and HVAC
- Utilize knowledge of thermodynamics, fluid flow, and control theory to design and analyze power plant process and utility fluid systems
- Model piping assemblies using CAD software and perform piping stress analysis
- Read and develop detailed piping and instrumentation diagrams of complex fluids systems
- Select components, such as valves, pumps, piping, tanks, heat exchangers, and filters, and provide detailed specifications for their purchase
- Coordinate with engineers from other disciplines (civil, structural, electrical, controls, etc) to establish a complete system design
- Manage the fabrication and installation of fluid systems and other construction projects occurring at the power plant, hands-on in the field, alongside skilled technician teams
- Perform planning, analysis, and troubleshooting of system performance during real-time plant operations, commissioning, and post-outage data reviews
- Work closely with operations teams to ensure system design is well-understood and easy to operate long term
- Provide innovative solutions to problems under minimal supervision or direction

## BASIC QUALIFICATIONS:

- Bachelor's degree in an engineering discipline
- 1+ years of experience with fluid systems or process engineering

## PREFERRED SKILLS AND EXPERIENCE:

- Master’s degree in mechanical, chemical, or related engineering discipline
- 5+ years of hands-on experience working with industrial fluid systems in a professional setting or outside the classroom project team
- Experience with fuel gas, ammonia (storage, delivery, and/or process use), water treatment or cooling water, compressed/instrument air, and HVAC or chilled-water systems
- Demonstrated expertise in the design, build, and operation of pressurized fluid systems per ASME B31, ASME B&PV Code Section VIII, or other applicable standards
- Experience using Siemens NX, SOLIDWORKS, or similar CAD software
- Experience using CAESAR II or similar pipe stress analysis programs
- Experience using python or other programming languages for data review and analysis
- Familiarity with industrial piping, fittings, and specifications (ASME/ANSI)
- Familiarity with instrumentation selection in industrial or severe service
- Experience operating and troubleshooting control systems required for remote or plant operations
- Excellent written and oral communication, especially translating technical concepts for non-technical audiences
- Ability to work with and lead technicians during fabrication and commissioning of systems
- Familiarity with Root-Cause Analysis and Risk Mitigation process
- Adaptability to change in direction of projects

## ADDITIONAL REQUIREMENTS:

- Must be willing to travel to other SpaceX locations as necessary
- Schedules vary due to plant operational needs - flexibility is required
- Ability to lift up to 25 lbs. unassisted
- Lifting, standing, climbing, bending, grasping, sitting, pulling, pushing, stooping, stretching, and carrying are generally required to perform the functions of this position

## About xAI

## Company Overview
- **One‑liner**: xAI builds artificial intelligence systems to accelerate human scientific discovery and “understand the universe,” with products spanning frontier reasoning models, real‑time voice, and generative media.
- **Entity Type**: Private (last funding round: Series E, January 2026; acquired by SpaceX in February 2026)
- **Headquarters**: Palo Alto, California, USA (additional offices in Seattle, WA; Memphis, TN; London, UK)
- **Founded**: 2023
- **Founders**: Elon Musk

## Core Business
- Primary industry: Artificial Intelligence (AI research, large language models, voice AI, generative media)
- Target customers: B2B (developers via API), B2C (consumers via Grok on 𝕏, SuperGrok subscriptions), Enterprise & Government (xAI for Government)
- Mission: “To understand the universe” – building AI that extends what humanity can know and do.

## Products & Services
- **Grok (base models)** : A conversational AI assistant modeled after *The Hitchhiker’s Guide to the Galaxy*, available on the 𝕏 platform and via API.
- **Grok 4 / Grok 4 Heavy**: The most intelligent reasoning models, featuring native tool use and real‑time search integration (SuperGrok and Premium+ tiers).
- **Grok Voice Agent API / Voice Agent Builder**: Create custom voice agents in under two minutes (no‑code) – includes speech‑to‑text, text‑to‑speech, custom voice cloning, and multilingual support.
- **Grok Imagine API**: State‑of‑the‑art video generation API (quality, cost, latency).
- **Grok‑1.5 / Grok‑2 / Grok‑2 mini**: Earlier model releases with improved reasoning and 128K context length.
- **PromptIDE**: An integrated development environment for prompt engineering and interpretability research.
- **xAI for Government**: A suite of frontier AI products tailored for U.S. government customers.
- **Colossus Supercomputer**: 200,000‑GPU cluster built in 122 days, used for training xAI models; now also leased to Anthropic (Colossus 1 agreement).

All products are delivered as SaaS, API, and model weights (open‑source release of Grok‑1).

## Market Standing
- **Valuation / Funding**: 
  - Series B (May 2024): $6 B 
  - Series C (Dec 2024): $6 B (led by A16Z, BlackRock, Fidelity, Kingdom Holdings, Lightspeed, MGX, Morgan Stanley, OIA, QIA, Sequoia, Valor, Vy Capital, others)
