Latest / The Career Change Podcast with Fexingo: Switching Fields, Bootcamps, and Reskilling / How Bootcamp Grads Can Break Into Ad Tech
Transcript
- Lucas: So Luna, we get a lot of questions from bootcamp grads about industries that feel a little mysterious from the outside. And one that keeps coming up is ad tech. Everyone's seen the banner ads, everyone's been retargeted by a pair of shoes they looked at once, but nobody really knows how the sausage gets made. Luna: Right, and it's not just the creepy factor. There's actual engineering and data work behind those ads, and it's a huge industry. So where do we even start? Lucas: Let's start with the reality that ad tech is essentially a data engineering and real-time bidding problem. When you load a webpage, there's an auction happening in the background in milliseconds. That auction involves multiple players, and each one is running sophisticated algorithms to decide whether to show you an ad and how much to bid. Luna: And bootcamp grads often think they need a computer science degree to touch that. But actually, a lot of the roles are accessible with the right skills and a portfolio. Lucas: Exactly. And speaking of portfolios, this is a good moment to mention something about the show. We keep this podcast free and ad-free because we believe career advice should be accessible to everyone, not gated behind a subscription or a paywall. If you've gotten value from episodes like this one, and you want to support that mission, you can buy us a coffee at buy me a coffee dot com slash fexingo. It's a small way to keep the lights on, and we genuinely appreciate it. Luna: Yeah, it's a nice way to say thanks without any strings attached. We're not selling anything, just keeping the podcast sustainable. Lucas: So, back to ad tech. The first thing to understand is the landscape. On one side you have the demand side, which is brands and agencies, and on the other you have the supply side, which is publishers. In between, you have platforms that connect them, like demand-side platforms, or DSPs, and supply-side platforms, or SSPs. Luna: And then there's the data management platforms, or DMPs, that hold all the user data. It's a whole ecosystem. Lucas: Right. And for a bootcamp grad, the entry point often comes through the engineering side. Companies are constantly looking for people who can build and maintain the tools that make this auction possible. That means JavaScript, Node.js, maybe some Python, and a lot of experience with databases and APIs. Luna: Let's talk about the skills specifically. What should a bootcamp grad highlight on their resume to catch a recruiter's eye? Lucas: First and foremost, JavaScript and Node.js are almost non-negotiable. The entire ad-serving pipeline is built on Node.js for many companies. Second, understanding how to work with large datasets, even at a basic level, is a huge plus. You don't need to be a data engineer, but knowing your way around SQL and maybe a little bit of data streaming concepts will go a long way. Luna: And what about the interview process? I've heard that ad tech interviews can be pretty intense on the system design side. Lucas: They can be, but there's a pattern. You'll often get a question like, 'Design a simple ad server' or 'How would you implement a real-time bidding auction?' And that's where your bootcamp projects can really shine if you've built something similar. Luna: So what would a killer portfolio project look like for ad tech? Lucas: I'd suggest building a simplified ad exchange. You can create a mock webpage that makes an ad request, then have a server-side auction that takes bids from a few mock bidders, and then returns a winning ad creative. It doesn't need to be production-ready, but it shows you understand the core flow. You can even throw in some basic machine learning, like a simple click-through rate prediction, just to show you're thinking about optimization. Luna: That's such a good idea. And it's way more specific than a generic CRUD app. Lucas: Exactly. But beyond the tech, there's a whole layer of privacy regulation that's now central to ad tech. With GDPR and CCPA, companies are scrambling to handle consent, data minimization, and user transparency. That creates a need for people who understand both the technical and the compliance side. Luna: So a bootcamp grad who's taken the time to learn about privacy frameworks could actually stand out. That's a smart angle. Lucas: Absolutely. And it's not just about GDPR and CCPA. There's also the upcoming deprecation of third-party cookies, which is changing the entire industry. If you can speak to that in an interview, you're showing that you're not just a coder, you're someone who follows the industry. Luna: Let's talk about the human side. What soft skills matter in ad tech? Lucas: One thing that surprises people is the importance of communication and negotiation skills. In ad tech, you're often working with both technical teams and business stakeholders. For example, you might need to explain to a media buyer why a certain campaign underperformed, or work with a publisher to troubleshoot integration issues. Being able to translate between the two worlds is incredibly valuable. Luna: And there's also the fast-paced nature of the industry. Ad tech moves at the speed of a click. How do bootcamp grads adapt to that pressure? Lucas: It's about being comfortable with ambiguity and constant change. The industry is always shifting, whether it's a new privacy law, a new ad format, or a new algorithm. If you're the kind of person who gets excited by that, ad tech can be a really fun place to work. And bootcamp tends to teach you how to learn quickly, which is exactly what you need. Luna: So, what's the actual job market like right now? Are companies hiring bootcamp grads for ad tech roles in 2026? Lucas: It's surprisingly robust. With the rise of connected TV and digital audio, ad spend keeps growing, and so does the need for engineers. There's also a lot of movement toward in-house ad tech teams at major brands, which opens up even more entry-level positions. A bootcamp grad with the right portfolio and some networking can absolutely land a role. Luna: Networking is key. How do you recommend a bootcamp grad start building connections in ad tech? Lucas: Start by attending industry events, like the IAB's annual meetings or local ad tech meetups. LinkedIn is also your friend. Reach out to people who work at companies like The Trade Desk or Magnite, and ask for informational interviews. Most people are happy to talk about their work, and it's a great way to learn the specifics. Luna: And don't forget about the bootcamp's own alumni network. There might already be graduates working in ad tech who are willing to refer you. Lucas: That's a great point. On that note, let's talk about a real-world example. I remember a story of a bootcamp grad who transitioned from teaching English in Japan to a role at a demand-side platform. He built a simple ad server as his capstone project, and during the interview, he was able to walk the team through his code and explain the trade-offs he made. That's what sealed the deal. Luna: It's a great reminder that showing your work is more important than just listing skills on a resume. Lucas: Exactly. And one more thing, if you're coming from a data science bootcamp, there's a whole other path. You can focus on modeling and optimization, like predicting click-through rates or building audience segments. That's a very different skill set, but just as in demand. Luna: So, to wrap up, what's the one thing you want our listeners to take away from this episode? Lucas: I'd say don't be intimidated by the jargon. Ad tech is just a bunch of systems talking to each other, and if you can build a simple version of that in your spare time, you're already ahead of most applicants. It's a field that rewards curiosity and initiative. Luna: And if you're a bootcamp grad who's made the leap into ad tech, we'd love to hear your story. You can reach out on Twitter or LinkedIn.
