Nextimox Technologies is a product software company building modern platforms that make complex business operations simple. Our products cover workflow automation, data and analytics, enterprise systems and system integrations, built for international markets.

We're building our main R&D team in Prishtina from the ground up. That means the people who join now help shape our architecture, our engineering standards and our culture, with real ownership over what they build.

About The Role:

We are looking for a Senior Java Backend Technical Team Lead who combines deep hands-on engineering expertise with the ability to guide a high-performing development team. In this role, you will design, build, and scale modern distributed systems, software infrastructure, and shared backend services that support multiple development teams and business-critical, high-availability products. You will remain close to the code while leading technical design, mentoring engineers, setting engineering standards, and taking end-to-end ownership of delivery- from architecture and implementation through testing, deployment, monitoring, and ongoing production support.

This is an opportunity to lead by example in a senior engineering environment focused on scalable backend platforms, production excellence, and continuous improvement. You will directly influence architecture, code quality, delivery practices, and team effectiveness while contributing hands-on to systems that support reliable product delivery at scale.

Key Responsibilities

• Lead the design and hands-on implementation of scalable APIs, distributed systems, and backend services that power high-availability applications.
• Own the full software development lifecycle, from architecture and technical design through implementation, automated testing, deployment, monitoring, and long-term production support.
• Maintain and optimize systems for performance, scalability, security, and reliability at scale.
• Collaborate closely with product owners, designers, QA engineers, and developers to translate business goals into scalable, maintainable technical solutions.
• Provide technical leadership through hands-on coding, code reviews, architecture guidance, design discussions, mentoring, task breakdown, and consistent engineering best practices.
• Set and uphold technical excellence and production-readiness standards, including clean architecture, resilient design, quality gates, release discipline, operational ownership, and pragmatic technical decision-making.
• Design and evolve event-driven architectures and asynchronous integrations using Apache Kafka, RabbitMQ, and related messaging patterns, while improving shared libraries, internal platforms, developer tooling, CI/CD workflows, and observability solutions.
• Promote responsible AI adoption across development and SDLC activities, using AI-assisted tools to improve code quality, testing, documentation, productivity, and delivery predictability.

Required Experience and Qualifications

• 6+ years of backend development experience with strong expertise in Java and object-oriented design, including at least 2-3 years in a technical lead or team lead role.
• Advanced practical experience with Spring Boot and the Spring ecosystem, including building RESTful APIs and microservices.
• Solid knowledge of design patterns, system architecture, distributed systems, and scalability principles.
• Hands-on experience with databases (SQL/No
  
  SQL) and message-driven systems using Apache Kafka and RabbitMQ, including producers, consumers, topics, retries, dead-letter handling, and idempotent processing.
• Experience with containerization and orchestration (Docker, Kubernetes), CI/CD pipelines, and cloud platforms.
