Senior Frontend Lead

We are looking for a Frontend Lead to join our E-commerce team at Tre, where you will play a key role in shaping the frontend architecture, engineering practices, and long-term technical direction within a cross-functional product team.

This role is a great fit for someone who combines strong technical expertise with a collaborative and coaching leadership style, and who is passionate about building scalable, maintainable, and high-quality solutions. You are also curious about how AI is transforming software development and see AI-assisted ways of working as a natural part of modern engineering.

About the role

As Frontend Lead, you will take technical ownership of the frontend domain and play a key role in shaping the architecture, engineering practices, and long-term technical direction of our e-commerce platform.

This is a hands-on leadership role where you combine active development with technical guidance, coaching, and cross-functional collaboration. Together with architects, backend developers, product stakeholders, and the rest of the E-commerce team, you will create scalable, maintainable, and business-critical solutions with a strong focus on quality, performance, and customer experience.

You will guide technical decisions, support the team in solving complex challenges, and help establish sustainable ways of working that enable high delivery quality and long-term maintainability. You will also contribute to improving CI/CD, testing strategies, release flows, and developer experience.

A key part of the role is ensuring that integrations between frontend, backend, CRM, CMS, and other systems work reliably and efficiently in practice. You will also help drive modern AI-assisted engineering practices within the team, exploring pragmatic ways of working with tools such as GitHub Copilot and Spec-Driven Development while maintaining high standards for quality, security, and maintainability.

You will play an important role in the continued development of our new web shop platform and the future frontend landscape within our Nordic e-commerce organization.

More about youWe believe this role is a great fit for someone who combines strong technical expertise with a collaborative and pragmatic mindset. You enjoy taking technical ownership, coaching developers, and building scalable, maintainable front-end solutions in close collaboration with architects and backend teams.

You have several years of experience building complex and preferably transaction-heavy web applications using React, Next.js, and TypeScript. You are comfortable working with API-driven architecture, modern frontend engineering practices, CI/CD pipelines, automated testing, and monorepo environments. Experience working in environments where frontend solutions are integrated with larger commercial or enterprise platforms is highly valued.

You value quality, performance, accessibility, and long-term sustainability, and you are confident in making sound engineering trade-offs when needed. Experience with frontend observability, headless CMS platforms such as Contentful, and AI-assisted development tools and workflows is considered a strong advantage.

You communicate fluently in English and thrive in agile, cross-functional product teams. Experience from larger organizations, telecom, or complex enterprise environments is considered an advantage.
