Senior Frontend Engineer

<h3><strong>An ode to our Senior Frontend Engineers 🌹</strong></h3> <p>clears throat*</p> <p>To us, you are like Leonardo da Vinci. A scientist, an artist, an engineer, a theorist, sculptor and architect. Out of your creative mind sprang a desire to understand how things work behind the scenes.</p> <p>It’s a little like fractals in nature. There is a mysterious mathematical complexity behind them, but most people only see a pretty pattern. You, dear frontender, see the link between them. You are interested in the mathematics underneath the beauty, you want to understand why the mathematics produces something that is beautiful, <em>and</em> you have appreciation for the thing that is beautiful.</p> <p>You tackle complex technical challenges and create elegant solutions for our end users. You work closely with our Designers and Product Managers to create the user experience – and you never just get handed a design without having key creative input. You constantly build reusable components for the entire system. You are excited by making a dropdown menu that solves for any kind of use cases we might want to create in the UI. You do all this not just by being a master of your craft, but by taking ownership and leading on large projects such as product launches. Mostly, we look up to you and learn from you, because you set the standard for the team, not just in code but in culture too.</p> <p>In short, you blow our minds every single day 😍</p> <h3><strong>We're looking for someone who has the following qualities:</strong></h3> <ul> <li>You care deeply about your craft and about quality</li> <li>You care deeply about product and design</li> <li>You are proactive and confident in your skills</li> <li>You can work in a lean environment</li> <li>You can organize work across teams</li> <li>You are comfortable working in a multidisciplinary environment, and especially comfortable working with designers</li> </ul> <p>You will be responsible for taking the project end-to-end from ideation to delivery and for stewarding efforts that involve two or more product teams across the organization.</p> <p>To complement your personal qualities, we expect that …</p> <h3><strong>You know your way around:</strong></h3> <ul> <li>Modern JavaScript, CSS and Web APIs</li> <li>Component-based, declarative UIs (we use React)</li> <li>Accessibility in web apps</li> <li>CSS-in-JS (we use styled-components)</li> <li>Linting and testing frameworks (we use Jest + RTL and Cypress)</li> <li>Static types (we use TypeScript)</li> <li>Data fetching and mutations (we use tRPC, SWR)</li> <li>Tooling for frontend teams and shared component systems (we use Storybook)</li> <li>Internationalisation/i18n (we use LinguiJS)</li> </ul> <h3><strong>Your colleagues say you</strong></h3> <ul> <li>Work in English with ease (it's our company language)</li> <li>Never stop being curious and love learning about new languages/ frameworks/ working styles</li> <li>You keep track of your promises – at least your JavaScript ones</li> <li>Accidentally start sentences with npm because you’re so used to typing it</li> <li>Evangelise ES6, ECMAScript 2018, ES2022, or know better than we do what the newest standard is</li> <li>Have experience solving complex technical challenges at scale</li> <li>Ensure a high bar for quality and reliability on your team</li> <li>Coach others on your team to help them develop as engineers</li> <li>Advocate for a more thorough code review process than a quick scroll to the bottom of the page and a “LGTM!”</li> <li>You don’t just write code, you help to design the overall solution</li> <li>Would be a person that they would actually like to have a coffee with (virtual or not)</li> <li>Somehow find a way to debate the merits of server vs client side rendering in that aforementioned coffee chat</li> </ul> <p></p> <ul> <li>Your own Pleo card (no more out-of-pocket spending!)</li> <li>Lunch is on us - with catering in our Lisbon, Copenhagen and London offices or a monthly lunch allowance paid directly together with  your salary in other markets 🍜</li> <li>Private health insurance to ensure you’re fit in body and mind to do your best work</li> <li>Option to purchase 5 additional days of holiday through a salary sacrifice</li> <li>Wellbeing days - fully paid days off designed for a slower pace, allowing you to take time to recharge and prioritise self-care</li> <li>We’re trialling MyndUp to give our employees access to free mental health and wellbeing support with great success so far  ❤️‍🩹</li> <li>Access to LinkedIn Learning - acquire new skills, stay abreast of industry trends and fuel your personal and professional development continuously </li> <li>Paid parental leave - we want to make sure that we're supportive of families and help you feel that you don't have to compromise your family due to work 👶</li> <li>All of us have a stake in Pleo’s success - ask us about our equity grant scheme</li> </ul> <p> </p> <p>#LI-Remote</p><p><strong>Why joi
