About The Company

Pragmatike is recruiting on behalf of a fast-growing, early-stage European startup building an API-first SaaS platform.

The company is developing developer-focused infrastructure products, with a strong emphasis on scalability, performance, and real-time processing. The product is already in the market, and the team is now focused on scaling the backend systems and expanding core capabilities.

The environment is fast-paced, highly technical, and product-driven, with a strong engineering culture.

About The Role

We’re looking for a Backend Engineer who is a strong builder and comfortable working in a modern AI-assisted development environment (e.g. Cursor, Claude Code, Copilot).

This is a hands-on role focused on building and scaling backend systems, APIs, and infrastructure. You’ll work closely with a small team to ship quickly, improve system performance, and design scalable architectures.

Your Responsibilities

• Build and scale backend services and APIs powering the core product
• Design systems that handle real-time processing and high-throughput workloads
• Improve performance, reliability, and scalability of the platform
• Work on data flows, async processing, and system integrations
• Contribute to infrastructure and deployment pipelines
• Use AI coding tools (Cursor, Claude Code, etc.) to accelerate development and iteration
• Collaborate closely with engineers and founders on architecture and technical decisions

• 4+ years of backend engineering experience
• Strong experience building and shipping production systems
• Proficiency in backend development (language-agnostic mindset; Node.js, Python, Go, etc.)
• Experience with APIs, distributed systems, and scalable architectures
• Familiarity with cloud environments (AWS, GCP, or similar)
• Comfort working in an AI-assisted coding workflow (Cursor, Claude Code, Copilot, etc.)
• Solid understanding of system design, performance, and reliability
• Ability to work autonomously in a small, fast-moving team

• Experience with real-time systems or event-driven architectures
• Familiarity with media processing, automation, or bot systems
• Experience with message queues, caching, and async workflows
• Exposure to low-level performance optimization or systems programming
• Startup or early-stage experience

• Early-stage team with strong ownership and impact
• Opportunity to build and scale core backend systems from early days
• Work in a fast-moving, engineering-first environment
• Modern stack and AI-native development workflows
• Fully remote and flexible setup
