GREV TUREGATAN 21, STOCKHOLM, Schweden

Lead Engineer The loyalty industry has stood still for too long. We're changing that. Member organizations and customer clubs have spent decades trying to create engagement with clumsy tools that don't adapt to individual members. The same offer to everyone. No personality. No memory. Perks is different. We've built a loyalty platform from the ground up. The product is modular, scalable, and white-label—each organization can assemble their own experience from reusable components and make it completely their own. The result is portals that feel personal and relevant to each individual member, not a shelf of generic campaigns. Treats Nordics AB is the company behind Perks. We're a small, experienced team working with a strong focus on AI-assisted development under clear technical guidelines, where the decisions that matter are made by people who know what they're doing. How We Build The usual way to introduce AI into development is to give everyone a tool and hope for the best. We did the opposite. First, we wrote down what applies to us: a technical contract that describes what counts as finished work, which rules are hard, and what should never pass through. Then we made the contract executable. The hard rules are enforced mechanically as code is written, not in a review long afterwards. The effect is that we can let the machine do a large part of the work without quality being just a hope. The repetitive disappears, and what's left are the trade-offs. We work the same way into the product. We have a built-in assistant that works with real tools and real data in the platform, and that part is growing fast. The work involves context architecture, tool design, quality, and cost in production. It's not about model training. At the same time, none of this is finished. No one yet knows what senior engineering work looks like when the machine writes most of the code. There's no course to take and no established practice to copy. We've come further than most, but we're still in the experiment, and some of what we're trying now will prove to be wrong. Working here therefore means not just working close to AI. It means being part of moving the boundary of what AI-assisted development can do. The methods we use a year from now are ones that someone on this team will have figured out, and we hope several of them are yours. We don't think AI makes judgment less important. We think it makes judgment nearly the only thing that's left, and that sets higher demands on those making the decisions. About the Role This is the most senior technical role after the founder. About 60 percent of the time you write code in the product. The rest goes toward setting direction, reviewing others' work, and ensuring that decisions made in an office conversation land correctly in the codebase. You build features across the stack, from database to interface. We don't separate work into frontend and backend. You own the AI-driven parts of the product, and you also own the way of working we described above. The guidelines are not carved in stone. They're code, and we expect you to change them when you see something better. We expect you to try things we haven't tried, and to tell us when something we're doing doesn't hold up. You drive the work together with our team in Sri Lanka. That means you write specifications that someone else can build from without sitting next to you, you review their code, and you set standards that hold even when you're not looking. The time difference is three and a half hours, and much of the communication happens in writing. We Believe You have built and driven products in production for several years, and can do the full journey from data model to interface have built product features on top of language models and know what breaks when they meet real users and real costs have your own view on how AI-assisted work should be organized—ideally one that differs from ours—and want to help shape the way of working rather than just work within it have led or mentored other developers, ideally in another country or time zone can write down a decision so someone else can build the right thing without asking you are comfortable saying no, even to us, and can explain why work smoothly in both Swedish and English What You Get A role where you actually matter. Where your decisions are visible. You get real authority, not a title, and you'll feel the consequences of your decisions within weeks. You avoid technical debt someone else created. You avoid bureaucracy. You work in a modern codebase where AI handles the repetitive and you spend your time on what actually requires judgment. In short: a job that feels meaningful in five years too.
