From academia to Amazon, Justine Hastings shares 5 lessons she’s learned from leading in a traditionally male-dominated field.

Behind Amazon’s strategy for employee opportunity and growth lies a crucial component that fuels decision making: science. Amazon’s workforce plays an integral role in innovating for the future, and Justine Hastings, VP of People eXperience and Technology (PXT) Science for Amazon, is at the center of this people-first strategy.

Hastings and her team, PXT Central Science, are dedicated to helping HR teams make fact-based decisions to support tomorrow’s leaders. They generate scientific insights and tools to simultaneously improve Amazon and the lives, well-being, and experience of Amazon employees globally. Hastings attributes her team’s success to two things: building a diverse science team and keeping the team focused on identifying and solving problems for customers.

Though improving, women remain underrepresented in the field of Economics at a time when movements for gender equity across industries continue to highlight the need to improve diversity and representation in workplace leadership.

One of Hasting’s priorities is supporting diverse talent. She makes time to invest in future science leaders, especially women, who are traditionally under-represented in science graduate programs. She understands making science accessible is key to fueling the marketplace of ideas.

Hastings came to Amazon 2.5 years ago from a tenured faculty position at Brown University, and has built a team where women are leading science at all levels, and different disciplines are encouraged to collaborate to solve complex customer problems.

Women have made incredible progress in the workforce. They have fought for equal pay, and risen to the top of their fields in recent decades. But some industries have made more progress than others.

Today, women lead many of Amazon’s largest and most important businesses, including our overall delivery experience, Amazon Fresh, AWS Public Sector, and more. Their leadership and influence at Amazon is growing in the traditionally male-dominated fields of technology and science.

Hastings shared with us her central inspirations when building and leading teams, and advice she gives herself and her team as she continues to learn and grow as a leader.

    Teamwork makes the dream work.

    Across industries, the challenges we face are large-scale, complex, and ambiguous. Solving them takes a diverse team of people with unique skills, specializations, and perspectives. Together, they accomplish much more than they could alone. One of the things I enjoy most about solving complex science problems at scale is creating the opportunity for people to come together and work as a team. Facilitating those magic moments where people think bigger and deliver better outcomes is most rewarding to me. This only happens when teams forget themselves and focus on accomplishing a mutual goal together—for example, solving a customer need.

    Hear people.

    Inclusive leaders work to hear all ideas and encourage people from all backgrounds to bring their ideas to the team. I remember when I was a junior faculty member, just starting to publish and trying to get tenure in a field with few tenured women and in a department where, to my knowledge, no woman had successfully been promoted to prior. A senior colleague told me that he struggled to appreciate my science contributions in seminars because women sound different than men. I felt discouraged, but then determined that I would work to carefully hear ideas no matter what tone or dialect they are delivered in. Important ideas come from a diversity of leaders with unique backgrounds and experiences. My job as a leader—and a human—is to work to understand others so that everyone has the opportunity to contribute their best. I strive to get better at hearing and understanding others every day.

    Why not me?

    It can be hard to step forward to lead when you are the only one from your background in the room. I was often the only woman in the room at academic events. Social norms for women discourage self-confidence and ambition. One of my favorite research papers shows that female MBA students shade their stated ambitions on internship applications when their application would be shared publicly. When you see a problem and have an idea for a solution, ask yourself: “Why not me?” Why shouldn’t you be the source of and leader for the solution? The worst that can happen is that you fail, learn something, and try again. The best that can happen is that you achieve something meaningful with bravery, determination, and hard work, and in so doing, encourage others to do the same.

    Find mentors, and be a mentor.

    Leading from an underrepresented background presents specific challenges. Leading will be hard, and the research is clear on this. For example, a recent study showed that in online Economics forums, when women scholars were discussed, the topic was their physical appearance and top words used were sexually explicit; when men were discussed, the topics pertained to their scholarship and research. To advance in society, we must find mentors to learn from. Beth Galetti is a key mentor of mine. Beth insists on the highest standards while leading with empathy. She is always there to gut-check my ideas and approaches, helping me hone my “Are Right, A Lot” skills with her deep and broad experience. Amazon is full of amazing women mentors who can provide perspective on what’s ahead by saying, “I’ve been there before. Here is what I did.” Find professional women’s groups and participate in them. Take time to share your experiences with mentees. Talk about the ugly things you’ve experienced. They become less ugly and your mentees gain courage.

    Make sure your science is people-centered.

    To successfully address human problems, we must get specific and dive deep into the root cause of a problem, and that starts with getting to know the people behind the data. We must always work to personally understand the experiences of those who will be impacted by the solutions we’re seeking to develop. Once you understand the true experience of the customer you’re aiming to impact, you can identify the best methods to solve their problems. Combine methods. Solving complex problems often needs multiple methodological approaches. If you don’t specialize in a needed method, find someone who does and collaborate. You’ll have an opportunity to learn something new and deliver significant impact. Always put your customer at the center of every science tool you create, and use the best combination of methods to deliver meaningful, measurable results.
