We are looking for a Senior Software Engineer, who will like to join our Tech team in Copenhagen! We're looking for a senior full-stack engineer to join our Tech team in Copenhagen. Someone who's excited about where software development is heading and wants to help shape how we build with AI. As a member of our Tech team, you'll be an essential part of developing digital products together with our clients and the team around you. Since we're an agency, we work with a wide range of clients, typically in focused sprints where we build new products or improve products we've built with them before. Our stack is TypeScript with Next.js and React at its core, extending into backend services, APIs and integrations as projects demand. We're operating in a time of agentic engineering. AI agents are changing how software gets built, and we embrace that: we use agentic tools to ship faster and build AI-powered features into client products. At the same time, we know that reaching the quality we aim for means sticking to the fundamentals of good software development. Agents amplify good engineering, they don't replace it. We're looking for someone with strong fundamentals in architecture, code quality and judgment, who can put these new tools to work without compromising on craft. We have an excellent team across our Copenhagen, Montreal, London and Toronto offices. We'll throw challenges at you, teach you new things, learn from you, and make sure we grow together toward our ambition of setting new and higher standards for the web. Check out some of our work HERE .

Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
