Come and join us to create the future together!

For the role of Senior Frontend Engineer we are looking for candidates with a broad range of skills.

In order to backfill the position who provides deep hands-on expertise, guides other frontend engineers, and helps keep delivery predictable. The focus is frontend architecture and practical adoption of modern libraries / technologies—not security ownership. Spain (onsite / hybrid). Work primarily in CET with regular overlap to support distributed teammates (Portugal, Egypt, UK, India).

Responsibilities

• Build & evolve the frontend: implement features in React / TypeScript; shape component architecture, routing, data fetching, and state management (Redux and related patterns).
• Library & tooling adoption: assess, introduce, and operationalize modern libraries and tooling (migration plans, usage guidelines, guardrails).
• Code quality & mentoring: perform thorough code reviews, pair when useful, and coach teammates on readability, testability, and maintainability.
• Cross-functional collaboration: work closely with backend engineers on API contracts and with UX / design on design system usage and interaction details.
• Defect handling: triage, debug, and resolve bugs efficiently; prevent regressions with targeted tests.
• Communication & stakeholder updates: present demos, explain trade-offs, and provide concise feature updates to internal and external stakeholders / clients.
• Distributed delivery: coordinate hand-offs across time zones; use clear specs, acceptance criteria, and async communication.
• Documentation: record architectural decisions, patterns, and runbooks to reduce single-person dependency.
• Out of scope: security ownership remains with platform / security teams; collaborate as needed but do not lead it.

What you bring

• Expert React with Redux / state management (action / reducer patterns, side-effects, store composition) in production systems.
• Strong JavaScript (ESNext) and TypeScript proficiency.
• Solid understanding of frontend architectures (module boundaries, composition, state / data flow, performance, accessibility fundamentals).
• Proven experience with code reviews, collaborating with backend and UX / design partners, and working with distributed teams across time zones.
• Comfortable presenting work (demos, client updates) and communicating clearly with non-engineers.
• Familiarity with Agile methods; SAFe experience preferred (or solid Scrum ceremony participation: PI / quarterly planning, refinement, sprint planning, reviews, retros).
• Advanced level of English

Nice to have

• Exposure to Kubernetes, Docker, and GCP; understanding of CI / CD pipelines and observability basics.
• Experience with automated testing (unit, integration, E2E) and build / bundle tooling.

Benefits

• Hybrid work model
• Bonus on top of the gross salary.
• Meal voucher (Ticket Restaurant), additional to gross salary.
• Flexible working hours from Monday to Thursday, and an intensive schedule on Fridays.
• Intensive Summer Schedule during July and August.
• Up to 20 days per year of 100% remote work from other locations.
• Private Health and Life Insurance for employees.
• Optional Pension Plan.
• Access to an online learning platform for continuous training.
