Jobbeschreibung

Alohi is an AI-first SaaS scale-up on a mission to simplify how businesses work. Our products (Sign.Plus, Dial.Plus, Fax.Plus, and Scan.Plus) serve 5M+ customers worldwide, from small businesses to global enterprises. We're building category-defining tools that people actually love to use.

We started with seed support from FONGIT (Fondation Genevoise pour l'Innovation Technologique), backed by the State of Geneva. Since then, we've chosen to bootstrap our growth. This keeps us financially independent, customer-focused, and able to move fast without external constraints.

We're a lean, fast-growing team based in Geneva with strong traction across global markets. This is an entrepreneurial environment where you'll have high ownership, broad responsibilities, and direct impact from day one. If you want to build something meaningful in a fast-paced, innovation-driven company, without the chaos of early-stage uncertainty or the bureaucracy of a large corporation, this is it.

We are hiring a Senior Backend Developer to build and scale the server-side systems that power our products. You'll own the development of APIs, backend modules, and database architecture, ensuring high performance and reliability as we serve millions of users worldwide.

This position is fully on-site at our Geneva office.

Responsibilities

We're looking for a hands-on engineer who can design, build, and maintain backend systems that scale.

Backend Development

• Build and maintain mission-critical backend systems to support high-volume requests across our product suite
• Design and develop robust APIs and web services that power our frontend applications
• Develop and maintain backend modules, ensuring clean architecture and maintainable code
• Build backend infrastructure for AI-powered features, including integration with LLMs, model APIs, and data pipelines for machine learning workflows

Performance & Scalability

• Identify and resolve performance bottlenecks in a high-traffic, scalable environment
• Optimise database queries and system architecture to handle growing demand
• Ensure development tasks are completed within timelines with minimal defects

Infrastructure & DevOps

• Work with containerisation technologies (Docker, Kubernetes) to deploy and manage services
• Contribute to CI/CD pipelines and build systems to streamline development workflows
• Participate in on-call rotations to ensure system reliability and respond to production incidents
• Collaborate with cross-functional teams to deliver features end-to-end

Requirements

• 3–5 years of experience in backend software engineering, ideally in a technology-driven or SaaS environment
• Strong proficiency in Python
• Solid experience with complex data structures and databases (MongoDB, MariaDB, Elasticsearch)
• Able to critically evaluate and effectively use AI-assisted development tools while maintaining a deep understanding of the underlying code
• Strong Linux knowledge and hands-on experience
• Good understanding of HTTP, REST, web servers, and microservices architecture
• Experience with containerisation (Docker, Kubernetes)
• Familiarity with build systems and CI/CD procedures
• Ability to write clean, scalable, and well-tested code
• Strong problem-solving skills and attention to detail
• Fluent in English (written and spoken)
