Senior Software Engineer - Cards Experience EU

How we work At Perk, we believe the best work happens when great people come together in small teams, with a shared sense of purpose. You'll join a cross-functional squad where you have real ownership of a piece of Perk’s domains, a genuine say in what gets built, and the autonomy to make it happen. Each team to decide how to contribute to Perk’s company goals. We care about impact, and we trust our people to deliver it. AI at Perk AI is embedded in

how we work and what we build. On the engineering side, it spans the whole workflow: our Notion, Jira, GitHub and Slack are AI-connected so you get up to speed fast, and day-to-day it helps with specifying features, writing and reviewing code, and automated AI PR review on every pull request. When something goes wrong in production, AI surfaces context across systems quickly. We also embrace agentic coding, using AI as an active collaborator, not just a prompt-by-prompt co-pilot. We expect candidates to use AI tools in our coding interviews. The bar is understanding your code and owning what you produce. That reflects

how we work every day. Some examples of what it means to be a Senior at Perk Shape the bigger picture. You won't just build features, you'll refine the what to build and why . At Perk, senior engineers are expected to go beyond the technical solution and focus on the problem itself. You'll contribute to your squad's quarterly goals and long-term vision alongside your Product Manager and Engineering Manager. Architect for today and tomorrow. When a big change is needed in how our platform works, you'll be the one writing the design documents that lay the foundation. You'll become a guardian of your team's technical quality; spotting areas of investment, proactively managing technical debt, and making sure we don't let "busy work" crowd out the work that truly matters. At Perk, we believe in impact over effort : our customers see results, not the hours behind them. Your job is to make sure we're always investing our energy where it counts most. Lead across boundaries. Your influence won't stop at your own squad. You'll communicate complex ideas across multiple teams, proactively identify who needs to be involved, and drive alignment across the broader organisation. Whether it's coordinating a cross-squad initiative, contributing to one of our engineering guilds (where engineers from different teams align on shared technical topics), or pairing with architects on solution discovery, you'll operate comfortably beyond your immediate team. Raise the bar for everyone around you. Senior engineers at Perk are mentors, coaches, and bar raisers. You'll support less experienced colleagues through direct mentorship, thoughtful feedback during reviews, and by modelling what great engineering looks like in practice. You'll help Engineering Managers understand where

the team needs to grow technically, and you'll use spaces like guild meetings, design doc reviews, and pairing sessions to lift the overall standard. At Perk, we are a team ,
