Principal Fullstack Engineer (EMEA, Remote)
Location: Fully remote, EMEA timezone Start date: ASAP Languages: Fluent English is mandatory Industry: Cloud Computing / AI European SaaS
Pragmatike is recruiting on behalf of a European deep-tech company developing 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’re looking for a Senior Fullstack Engineer (Staff / Principal level) with strong expertise in React and Node.js, and a proven track record of leading or executing migrations from monolithic architectures to modern Single Page Applications (SPA).
This role goes beyond hands-on delivery: technical leadership, architectural ownership, and mentorship are key. Startup or hyper-growth experience is a strong plus. Autonomy, ownership, and the ability to make pragmatic technical decisions are essential.
Your Responsibilities:
- Lead the design and development of scalable fullstack applications using React (SPA) and Node.js.
- Own and drive monolith-to-SPA migration strategies, including incremental decomposition, API design, and frontend re-architecture.
- Define and enforce frontend and backend architecture, patterns, and best practices.
- Act as technical lead for the fullstack domain: reviewing designs, mentoring engineers, and setting engineering standards.
- Collaborate closely with product, DevOps, and platform teams to align application architecture with infrastructure constraints.
- Design and maintain backend services and APIs (REST/GraphQL) with a focus on performance, reliability, and maintainability.
- Improve application observability, performance, and resilience.
- Participate in hiring, onboarding, and growing senior engineering talent.
- Drive technical decision-making with a long-term platform mindset.
Why Join Us:
Our client is shaping the future of cloud infrastructure through decentralization and advanced automation. Their mission is to deliver a sovereign, energy-efficient, high-performance alternative to traditional cloud providers. You’ll join a highly technical environment where architecture matters, leadership is valued, and your decisions will directly shape the evolution of a complex, ambitious platform.
What You Bring:
- Senior-level experience (Staff / Principal) as a Fullstack Engineer.
- Strong expertise in React and modern frontend ecosystems (SPA architecture, state management, performance optimization).
- Strong experience with Node.js backend development and API design.
- Proven hands-on experience migrating monolithic applications to SPA or modular architectures.
- Ability to lead technical initiatives end-to-end.
- Solid understanding of software architecture, system design, and trade-offs.
- Experience working in fast-moving, product-driven environments.
- Excellent communication skills and ability to influence technical direction.
Nice To Have:
- Previous experience as Tech lead or project management role.
- Experience with microservices or modular backend architectures.
- Familiarity with cloud-native environments and modern CI/CD pipelines.
- Experience collaborating closely with DevOps or infrastructure teams.
- Prior experience in deep-tech, cloud, or infrastructure-heavy products.
- Exposure to performance-critical or high-scale systems.
