Senior Engineer

About this role

About Us We’re November Five. Makers, designers, strategists. Different backgrounds, one mindset. We say what we mean and do what we say. Passion walks in; expertise grows. Feedback is direct. We’re hard on the facts, but kind on the people. We wear more than one hat, and we’re proud of it. We collaborate hard and we’re always looking for more people like us. We’ve also built things of our own. Appmiral, Spencer, Gorilla, Wovian. Four ventures born inside November Five. When the right idea meets the right people, we build it. That’s not a side note. It’s part of who we are. About the Role We're not actively hiring right now, but we're always in conversation with engineers who can genuinely move the needle at November Five. If that's you, we want to talk. We're actively evolving towards smaller teams. Teams that don't care about roles in the strict sense. Engineers who do what's needed to make a project successful, who thrive in high-stakes, AI-led delivery, and who challenge the status quo rather than defending it. This isn't about growing headcount. It's about finding people who tangibly shift what we ship, how we ship it, and how the people around them work. Requirements What we're looking for 5+ years of engineering experience with a track record of measurable impact on products and teams Strong command of at least React, React Native, native Apple (Swift), or native Android (Kotlin) Active, daily use of AI tooling in your engineering workflow, with a clear point of view on where it's heading Agency or consulting experience, you understand client delivery, shifting priorities, and juggling multiple projects simultaneously Strong communication skills and the ability to give and receive candid feedback Comfortable working hybrid in Antwerp, 2-3 days per week on-site, non-negotiable EU work authorization, we do not offer visa sponsorship or relocation support Our technical environment We work across React, React Native, and native Apple (Swift) and Android (Kotlin). Depth in one stack and credibility across others matter more to us than strict specialization. We value engineers who pick the right tool for the problem, not the tool they've always used. AI is central to where we're going. We're not looking for engineers who are curious about AI. We're looking for engineers who already build with it. Benefits How you grow here We use our Impact x Growth x Reward (IGR) framework, to make progression clear and evidence-based. Your growth is tied to the impact you create: on clients, on the work, on the team around you. N5 is also a place where ideas become ventures. Four businesses have been built here already. If you’re working on something, we don’t ask you to leave it at the door. Why join us? Because the work matters. And so do our people. Ship real products for Coca-Cola, Le Pain Quotidien, Telenet, and others. Work with people who will tell you when something isn’t good enough. They mean it as a compliment. Build the design culture, don’t inherit someone else’s. Stay close to the craft while growing the team around you. A benefits package built around trust: mobility budget or company car, smartphone budget, mobile subscription, MacBook, pension plan, hospitalization insurance, net expenses, meal vouchers, 12 additional holidays and shared rewards. Work from our Antwerp HQ. Worth seeing for yourself.
