"Our CTO, Tiho Bajic, reached out to me when Nitro was getting ready to re-platform into the TypeSafe stack. Tiho presented me with an opportunity to join the team that was ultimately responsible for building the platform for the next generation of smart documents. I get it—PDFs aren’t necessarily the sexiest thing, but it was clear that our mission was so much more than that—the innovation of productivity workflows was really attractive to me. I mean, who likes papers floating around your workspace?! I hate printing documents out and scanning them—I don’t find that productive at all." – Greg Silin, Senior Platform Engineer


"Some engineering departments can foster an extreme blame culture—that is the opposite of what we’re trying to achieve at Nitro. We take risks and sometimes we break stuff, but usually it shows that we’re nimble and unafraid to make mistakes. We take calculated risks, and it’s beautiful when it all works out—our customers have a better, faster, and more polished product." – Brendan Dillon, Director of Engineering


“From our Sales development to our Sales management, we offer an environment that allows Nitronauts the opportunity to grow an exciting and successful career in sales. When I started, there were probably 50 Nitronauts companywide and now we are at about 150 and still growing." – Nick Hughes, Account Executive


"I loved that Nitro was very committed to technology, and specifically passionate about Scala. It was clear that Tiho and his team were creating a culture of engineering and 'always learning', which is what I’ve always done in my career. It was a perfect fit." – Devin Loftis, Director of Platform Engineering

"I’m from Boston, Massachusetts. The last winter in Boston was so brutal that I actually decided to move out to the West coast. I was looking at the Typesafe partner’s page and I came across various events organized by Nitro—meetups, hackathons—their Scala community involvement was what initially attracted me to the company. Then when I learned about their product offering—I was sold. It doesn’t hurt that the culture, people, and food around San Francisco is amazing, too." – Paul Kinsky, Platform Engineer


“The Nitro Marketing culture fits into the Nitro culture as a whole – we are definitely a creative and VERY silly bunch, but we know when to buckle down and get the task done.” Laine Riley, Project Manager


"I lived in Melbourne while I was in college and it was a special city for me. Nitro is Aussie-founded and it was a happy coincidence. I love the culture—it’s very fun yet performance driven—results are everything for us. I feel like I’m working with friends rather than just colleagues. It makes getting out of bed not too much of a struggle and being at work is a lot more enjoyable!” – Alex Acker, Online Marketing Manager


“It’s really simple: we’re all about being performance-driven, no bullsh*t and being good—to our customers, our candidates and most importantly, our employees.” – Jennifer Trendler, Director of Talent


"The culture at Nitro can be described as “employees first.” And—great for us—happy employees make for happy customers. Naturally, as a Sales department, we care a lot about hitting our goals, but we want to do it in a very collaborative and supportive way." – Dave Belove, VP of Sales Operations and Productivity

    Nitro has a lot of fun, hard-working people. It's been go-go-go since I started but all in the spirit of lofty (but achievable) goals. There's a lot of mentorship for those who seek it, and no shortage of learning opportunities as well. Results alone are highly valued, and great results (not tenure) lead to promotions. Very much a "Silicon Valley" company with all the perks: free drinks, free lunches, yoga, parties, etc. There's a palpable excitement around Nitro's growth, and I'm personally excited to be here at this stage. There's a unique amount of visibility and access to the executive level; feels more like an open-door policy than other companies I've been at. Extroverted people will see more success here. Grab lunch with your coworkers, get involved with extracurriculars, find your crew, etc.


    Most of the cons are by-products of the pros above. The go-go-go attitude can leave some in the dust, resulting in a bit more churn than I'm used to. Although it seems like these are largely growing pains as Nitro finds a new foothold and expands the company in new ways after its funding. A departure (layoff or otherwise) of a coworker can sometimes come as a surprise. Introverted people here will have a harder time. Help tends to be reserved for those who ask; if you don't ask, you probably won't be helped. Also, in the same way that good results are rewarded swiftly, poor results seem to be met with equal swiftness.

    Advice to Management

    Put more value on 1:1 mentorship (expand the Nitro-mate program beyond the first day).

    Operations Coordinator Interview

    Anonymous Employee in San Francisco, CA
    Declined Offer
    Positive Experience
    Average Interview


    I applied through an employee referral. The process took 2 weeksinterviewed at Nitro (San Francisco, CA).


    A few days after applying Jennifer the Head of Talent at Nitro reached out to me via email to set up a time for an over the phone interview. The conversation with Jennifer dove into experience, interests and future goals. It felt like a very comfortable and informative conversation. After visiting the offices and having an in person chat with Jennifer she was able to gauge my experience and felt pursuing the Operations Coordinator role would be a good fit. I then met with two members of the team, one of which was currently in the role and moving towards the next step and the other was Operations Coordinator manager. My interview with both was such an amazing experience. Both ladies gave me tons of insight on the role and asked great questions about my experience and really gauged who I truly was. They had a less traditional approach in that they really wanted me as a candidate to understand what Nitro had to offer so they didn't ask the general interview questions. They focused more on who I was and how I could contribute to the team and vice-versa. This was followed by a take home questionnaire. My last interview was with the awesome COO and her equally sweet assistant. This was a real treat, again I felt like we spoke open and honestly about what the role and amazing company had to offer and how my experience and who I was would fit into the groove of Nitro’s unique and caring culture. I was so grateful to be offered the position. Throughout the entire process both Jennifer and Lyla (talent coordinator) were amazing in providing constant feedback and communication. They genuinely took their time to get to know me as a candidate. Overall I had probably one of the most unique and amazing interview processes of my life. Nitro Rocks! The Nitro blog is a very cool tool to use when wanting to learn more about the company! Definitely something to look into as it has well written and interesting content in many different categories.
