Half code, half influence. Ready to shape how viewers become customers?At Q-tech, we collaborate with a leading streaming and entertainment group in the Nordic countries, home to top-tier live sports, original series and films.
They are looking for a hands-on Senior or Lead Engineer for their Barcelona hub to join the Commerce platform, which covers sign-up, checkout, payments and subscriptions.
You’ll split your time between writing code and supporting other teams with technical decisions, sharing knowledge and driving company-wide initiatives. This role has no people or budget management. Your impact comes from technical influence and evangelism.

Responsibilities:
Build scalable, resilient backend services in Node.js and TypeScript (with some Rust) on AWS.
Design integration strategies with third-party payment providers and commercial platforms.
Write real production code, including outside your own domain when another team needs support.
Technical evangelism and company-wide initiatives:Help define the technical direction of the Commerce platform in line with the long-term product vision. Support other teams on cross-cutting problems,



and take an active part in the engineering guilds and tech communities. Challenge the “why” before the “how”: make sure the teams are solving the right problem. Mentor engineers and favour solid solutions over trendy ones. Help teams reach good decisions instead of imposing them.

Requirements:
Solid experience as a Senior Engineer or Tech Lead, with a track record of influencing beyond your own team. Experience designing scalable cloud services on AWS, ideally serverless and event-driven. Experience with high-traffic, high-transaction consumer products. Ability to drive technical initiatives without formal authority. Hands-on experience with AI-assisted engineering practices. Experience modernising or migrating complex systems.
What is offered:Permanent contract and 30 days of paid holiday Hybrid model with 3 days a week in the Barcelona office Regular trips to Stockholm to connect with your peers A yearly Hack Week, and many of its projects make it into the product Private health insurance, adaptable compensation and meal vouchers
