As a Lead Engineer, you will play a dual role of execution and leadership. You will drive the technical direction of your team, make strategic decisions, and ensure alignment with business goals.

  • Collaborate to build the technical roadmap and support your team in executing it
  • Lead major technical decisions, set standards, and ensure alignment with business objectives
  • Guide, mentor, and support engineers in their technical growth
  • Combine strategic vision with hands-on execution when needed
  • After some time, participate in the on-call rotation
  • Communicate effectively with engineering, product, and business teams
  • Translate complex technical challenges into clear, actionable insights for non-technical stakeholders

Requirements:

  • 5+ years of experience in back-end development with strong proficiency in software engineering principles
  • Solid experience with Java and Spring
  • Strong knowledge of databases, including SQL, data modeling, and query optimization
  • Familiarity with DevOps practices such as CI/CD, containerization (Docker, Kubernetes)
  • Hands-on experience with testing (unit, integration)
  • Deep understanding of system design and architecture (design patterns, microservices)
  • Proven ability to design and implement scalable, reliable, and maintainable systems, with a focus on long-term quality
  • Be ready, after some time, to participate in the on-call rotation
  • Knowledge and practical experience with secure coding practices and protection against common vulnerabilities
  • Previous experience working with financial systems or billing platforms
  • Problem-solving – ability to identify issues, evaluate options, and implement effective solutions
  • Communication – strong skills in collaborating with teammates and stakeholders
  • able to translate complex technical concepts into clear language for non-technical audiences
  • Teamwork – works well within a team, actively contributes to a positive and supportive culture
  • Adaptability & learning – open to learning new technologies and adjusting to evolving requirements
  • Proactivity & ownership – takes initiative, raises challenges early, and drives progress toward team goals with accountability
