About the Role

Pragmatike is recruiting on behalf of a European deep-tech company building a decentralized, energy-efficient alternative to traditional cloud providers. Their platform operates on distributed bare-metal infrastructure with advanced automation, delivering sovereign, high-performance compute for modern workloads.

We are seeking a Senior / Lead Backend Engineer (Staff-level mindset) with strong expertise in Go and production-grade peer-to-peer (P2P) systems. This is a highly technical role focused on distributed systems, system-level programming, and performance-critical backend services.

You will play a key role in designing and evolving the backend foundations of a decentralized cloud platform, working closely with infrastructure, product, and DevOps teams. Autonomy, ownership, and strong architectural judgment are essential.

Your Responsibilities

• Design and develop scalable, distributed, server-side applications and microservices using Go.

• Build and optimize mission-critical backend software, with a strong focus on system programming, concurrency, and performance tuning.

• Design and implement robust peer-to-peer (P2P) communication systems (P2P experience is mandatory).

• Contribute to or build systems using libp2p or similar P2P frameworks.

• Ensure cross-platform compatibility and consistent application behavior across environments.

• Collaborate within an Agile/Scrum team, contributing to backlog refinement, risk identification, and dependency management.

• Produce clean, maintainable, and reusable code, following strong engineering standards.

• Optimize backend systems for performance, reliability, security, and fault tolerance.

• Establish and enhance backend infrastructure, including deployment pipelines, observability, and monitoring tooling.

• Work across multi-cloud environments (AWS, Azure, GCP) and collaborate closely with infrastructure teams.

• Participate actively in the full application lifecycle, from design to production operations.

• Engage with product and design teams to deeply understand end-user and platform requirements.

• Conduct thorough code reviews, mentor other engineers, and raise overall backend engineering quality.

• Champion best engineering practices and a culture of high-quality software craftsmanship.

Required Qualifications

• 5–6+ years of experience as a Senior or Lead Backend Engineer.

• MS degree in Computer Science or a closely related technical field.

• Strong hands-on expertise in Go and/or Java (Go strongly preferred).

• Solid understanding of software design patterns, concurrency, and multi-threaded programming.

• Proven production experience with P2P architectures (mandatory).

• Strong knowledge of internet protocols and technologies (TCP/IP, HTTP, etc.).

• Experience with service-oriented architectures (REST, JSON, API design).

• Ability to design secure, well-structured RESTful APIs and understand their client-side implications.

• Deep understanding of Agile development principles and collaborative team environments.

• Strong communication skills and ability to influence technical direction.

Preferred Qualifications

• Hands-on experience with Docker and Kubernetes.

• Experience in infrastructure engineering and running production systems.

• Strong skills in logging, tracing, and observability to diagnose production issues quickly.

• Proven track record building large-scale, high-availability, business-critical systems.

• Solid experience with multi-cloud deployments (AWS, Azure, GCP).

• Direct experience with libp2p, decentralized systems, or related open-source projects/startups.

• Familiarity with CI/CD pipelines and modern DevOps practices.
