Software Engineer (m/f/d) – Backend & Platform | AI-First Engineering

zvoove is a provider of software and AI solutions for staffing, cleaning, and security services industries. The company is seeking a backend and platform software engineer to modernize a business-critical Payroll platform, build APIs and services, and contribute to AI-first engineering practices. The role also involves evolving existing systems safely, strengthening engineering quality, and contributing to architecture and modernization decisions.

Responsibilities:

• Design and build modern backend services and platform capabilities around an established Payroll product
• Build APIs and integration points that allow Payroll capabilities to be used by modern applications and workflows
• Modernize the product incrementally rather than through a big-bang rewrite
• Work closely with existing engineers and Payroll domain experts to understand and safely evolve proven business logic
• Establish strong engineering practices around automated testing, observability, code quality and maintainability
• Use AI throughout the software development lifecycle to:
  • understand unfamiliar and complex codebases
  • analyse dependencies and behaviour
  • explore solution options
  • accelerate implementation
  • generate and improve tests
  • review code and documentation
• Help define how AI-first software engineering should work in practice across the team
• Collaborate with external Web/UI engineers while ensuring that core product architecture and engineering quality remain owned internally
• Contribute to technical architecture and modernization decisions

Requirements:

• Several years of professional software engineering experience with strong backend development skills in a modern programming language and ecosystem
• Experience designing APIs, services and integration-oriented systems, with a solid understanding of software architecture, clean boundaries and maintainable system design
• Comfortable working with existing or complex systems – not only greenfield products – and taking ownership from technical problem through implementation and production
• Strong automated-testing mindset and excellent communication skills, with a willingness to work closely with product and domain experts
• Practical experience using modern AI coding tools or engineering agents as part of day-to-day development, combined with the ability to judge AI-generated output critically
• Experience in one or more of the following is a plus: modernization of large or long-lived software products, strangler/incremental migration approaches, cloud and container-based environments, asynchronous processing, high-compliance or business-critical software (e.g. Payroll, HR or financial), legacy integration, or developer platforms and internal tooling
• Experience with C#/.NET, especially for backend services, APIs or modernization of established applications
