An Insider's view of Integral Ad Science

How would you describe the company’s work-life balance?

What I love about working at IAS is that everyone gives 100% at work, but everyone also respects that our lives outside work are important as well. The work-life balance at IAS is an important part of the company culture -- management recognizes that for employees to do their best work, we need the time to recharge and relax as well.


Global Agency Lead

How do you collaborate with other teams in the company?

Right from the beginning, I get everyone involved. I establish a space where we can get to know each other and our specific goals, and I keep people aware and engaged through transparent communication, clear timelines, & consistent check-ins. Ultimately, I see each project as an opportunity to foster a collaborative cross-functional culture at IAS.


Lead UX Researcher

What makes someone successful on your team?

Possessing both the desire to grok how complex things work and the diligence to pursue that trail of understanding are the key attributes I see in individuals who do really well on my team.


Vice President, CTV Strategy

How do your team's ideas influence the company's direction?

Data scientists are part of every step of the innovation cycle: we discuss needs with the product and leadership teams, we explore unknown data patterns, we prototype new solutions, and work with engineering in putting these new solutions in production.


Data Science Senior Manager

How do you make yourself accessible to the rest of the team?

It's more important than ever to have open channels of communication. We hold weekly virtual town halls where we keep everyone updated on important company news, but more importantly, open our leadership team up for questions. We have several open Slack channels where the team can ask about anything - from my US Open picks to our latest policies.
