Own the squad’s technical direction, primarily on the backend, with awareness of frontend implications
Design and evolve system architecture in a microservices and event-driven environment
Ensure high code quality through reviews, standards, and best practices
Collaborate with the Delivery Manager and Business Analyst to translate business needs into technical solutions
Align with other Tech Leads to ensure architectural consistency across teams
Identify, communicate, and mitigate technical risks and dependencies
Contribute hands-on to development on a regular basis
Communicate technical decisions and trade-offs clearly in English

Expected competences and knowledge

Minimum 7+ years of commercial experience in software development
Proven experience in a Tech Lead role
Strong hands-on expertise in Java and the Spring ecosystem (Spring Boot, Spring MVC, Spring Cloud)
Understanding of frontend and client-side architectures, with exposure to React and/or Flutter (ability to collaborate efficiently with frontend/mobile developers, review high-level solutions, understand integration points and trade-offs)
Very good understanding of fullstack application architecture
Experience with event-driven architectures (message brokers, asynchronous communication, events)
Practical knowledge of PostgreSQL or similar relational databases
Experience working with microservices and distributed systems
Strong mentoring and technical leadership skills
