National Oilwell Varco – Why Work With Us?

NOV has been pioneering innovations in the oil and gas industry since we first started doing business more than 150 years ago. We’ve seen the industry evolve one step at a time as the dynamics of the business have shifted, and we’ve been there each time to meet those challenges. We’re proud to continue contributing to an industry that impacts the lives of so many people, and now we’re looking to the future.

We recognize that the face of the oilfield is changing. Building more advanced equipment has historically been the industry’s answer to a need for transformation, but we feel that to really inspire change we have to drive a technology revolution. We’re using software algorithms, machine learning, and Big Data to deliver greater insight into our customers’ operations, optimize their performance, and increase their scale. We’re digitally managing assets and reducing equipment downtime through predictive analytics powered by an industrial data platform. We’re using advanced process automation to eliminate repetitive, time-consuming tasks, allowing drillers to focus on what’s really important and rigs to heuristically learn.

We are proud to be at the forefront of our industry and, when you join the NOV family, you also get to be an innovator with us.

At NOV, we believe in three core values that set the standard for how we do business and interact with one another: Family, Innovation, & Service.


Global Family

NOV offers you more than just a job – we offer you a place where you can truly become part of a global family. Each and every individual in this organization is important to us, across all disciplines and from all backgrounds. We firmly believe that those who take pride and ownership of their work, whatever they may do, truly power our potential to achieve greatness.

When we come together, we can do amazing things to create a lasting, meaningful impact for ourselves, our customers, and the communities where we live and work. We believe in accountability and responsibility – you build your own career because you understand the bigger picture and have the passion to tackle the industry’s challenges. Working at NOV means you’re building relationships that make coming to work fun and help you develop in your career.


Purposeful Innovation

Innovation is at the heart of everything we do because we know that to change the world, we must expect the unexpected and discover the undiscovered. We want people who use these opportunities to collaborate with their colleagues and build something better than what was done before.

We’ve pioneered some of the most recognized inventions in the oil and gas business – from capital equipment like the top drive to advanced digital technology like our optimization and automation programs – but we understand that innovation doesn’t simply stop with one major development. We must continue moving forward, pushing the boundaries of ourselves and our crafts, to achieve lasting success and build a legacy.


Service Above All

We believe in service above all, and that how we interact with our customers, each other, and our communities defines our company. Working with customers hand in hand to address their concerns and anticipate their needs allows us to consistently deliver the best value possible, while recognizing that people have unique needs that may not always fit a mold.

We stand with our customers every step of the way to ensure that financial goals are met and business is moved forward. Our people also deeply invest in local communities, allowing our core values to extend far beyond the office or the field. We proudly live the values we promote, making a difference one day at a time.

We understand that careers aren’t two-dimensional, and want to provide our employees a place where they feel empowered to ask the hard questions, deviate from the norm, and carve their own place in the company. We offer our employees a wide variety of learning and development initiatives, with coursework across technical and nontechnical topics available regardless of experience level. As a member of the NOV family, we invest in you – we want you to have the opportunity, throughout your career, to achieve your true potential.


We offer a wide variety of options for beginning or continuing a career at our organization. We want problem solvers who can think outside the box and understand how to create better solutions that transform the industry. We want diverse individuals who can work together as a team to bring together different perspectives to make an impact on the world. We want people who are more interested in learning and developing than climbing a corporate ladder. We want dreamers and thought leaders, those who can align ideas with reality and challenge the status quo. Our people are more than employees, and we strive to power their potential.

Our best work comes from the people who wholeheartedly believe that they make a difference with what they do, and we’re driven by these people to reach new heights. Our employees are, without a doubt, the company’s greatest asset, and we’re proud to have brought together some of the most talented people in the industry. Are you ready to be a part of our team?

Our employees, at locations around the world, support charitable organizations through awareness campaigns and fundraising initiatives. Whether it’s a coastal cleanup day or racing for a cause, we humbly come together to make a difference in the communities we call home.


We think that sustainable technologies are important for the future, and acknowledge that we all have a responsibility to give back. Sharing our passion for service ties back into NOV’s core values, reinforcing our commitment to taking pride in how we live and work.
