Senior Software Developer

Are you looking to join a fast-growing tech company?

We are looking for a Senior Software Engineer (Go / Kubernetes / Cloud-Native) to collaborate with a global, fully remote tech organization that originated as a Kubernetes-native open-source initiative and has since evolved into a leading enterprise-focused testing orchestration platform.

The company is currently scaling rapidly, backed by international investors, and operating with distributed teams across Europe, the US and Asia. You will play a central role in the evolution of a highly technical product used by engineering teams worldwide.

Responsibilities

• Develop backend features in Go, ensuring high performance, maintainability and clean architecture.
• Evolve and optimize the existing cloud-native platform built on Kubernetes.
• Design and implement distributed services, APIs and components for large-scale test orchestration.
• Collaborate with product and customer-facing teams to ensure strong alignment between technical decisions and user needs.
• Participate in the continuous improvement of the product, proposing scalable, reliable and customer-driven solutions.
• Maintain high standards in documentation, testing, observability and version control.

Requirements

• 8+ years of professional software engineering experience.
• Strong expertise in Go.
• Deep, hands-on experience with Kubernetes (development + operational).
• Solid understanding of cloud-native architectures, distributed systems and microservices.
• DevOps knowledge: CI/CD, networking, infrastructure, security, cloud environments (GCP preferred).
• Database experience with MongoDB and PostgreSQL.
• Strong communication skills and the ability to thrive in small, highly technical teams.
• Ability to perform in fast-paced, high-pressure, resource-limited contexts.
• Experience supporting customers or enterprise users.
• A strong product mindset, not just technical execution — able to understand real user needs and translate them into engineering decisions.
• Fluent English (this is the primary working language across teams)

Nice to have

• Experience with performance testing or functional testing tools.
• Background in open-source environments or developer-focused products.
• Experience working with distributed remote teams.

Work Arrangement

• 100% remote work.
• Opportunity to join a fast-growing, innovative company.
• Engagement as a freelance / self-employed contractor in Europe (Spain, Portugal, or other EU countries)
