We are a fast-growing team of 340+ engineers and consultants across Europe (UK, Spain, Portugal), the Americas (US, Argentina, Uruguay, Colombia), and the Middle East. We combine global reach with a mindset focused on agility, senior expertise, and close collaboration.

Our expertise spans software engineering, Al & data, product development, and customer experience, delivered by teams that combine strong technical depth with a consulting mindset.

• Coach and develop engineers, fostering a culture of excellence, continuous improvement, and knowledge-sharing.
• Manage stakeholders effectively across engineering and business functions, and report progress to senior leadership.
• Ensure system resilience, performance, production support excellence, and champion the responsible use of AI-assisted software development.

What you'll bring to the role:

• Strong backend development experience using Java and/or Kotlin, deep expertise in the JVM ecosystem, open-source frameworks, REST APIs, event-driven messaging, and databases.
• Proven experience building cloud-native applications, microservices, distributed architectures, and customer-facing platforms using AWS and multi-cloud environments.
• Experience with mission-critical systems, ideally in banking, payments, or card issuing.
• Expertise in testing, CI/CD pipelines, and modern software delivery automation.
• Exceptional problem-solving mindset, ownership mentality, and ability to operate effectively in ambiguous, rapidly changing environments.
• Demonstrated ability to coach and develop engineers, influence engineering direction beyond immediate team boundaries, and collaborate effectively across tribes and squads.
• Excellent stakeholder management and communication skills across business and engineering functions.

Location:
