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.
Why Join Us
Our client is redefining cloud infrastructure through decentralization and advanced automation, offering a sovereign, energy-efficient alternative to hyperscale cloud providers. Youll join a deeply technical environment where architecture matters, performance is critical, and your decisions will directly shape the evolution of a complex, ambitious platform operating at the intersection of distributed systems, networking, and cloud infrastructure.
