Lead/Tech Lead Java Engineer

Role Description

We are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software — not an experiment, not a trend, and not an optional add-on. AI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential—AI amplifies our engineers, it doesn’t replace responsibility for technical decisions.

What you will be doing:

• Design and implement complex, scalable system architectures while mentoring team members and driving technical excellence.
• Lead code reviews and establish best practices to ensure high-quality deliverables across the engineering team.
• Optimize database performance and design robust data solutions, particularly with PostgreSQL and query optimization.
• Architect and maintain messaging systems using Kafka or similar technologies to handle high-volume data streams.
• Troubleshoot and resolve complex production issues, taking full ownership of system reliability and performance.
• Facilitate technical discussions and foster collaborative problem-solving across cross-functional teams.

Qualifications

• Extensive production experience with Java and deep understanding of JVM internals and ecosystem.
• Strong system design capabilities with proven ability to document and implement complex architectures.
• Advanced knowledge of relational database principles, PostgreSQL expertise, and performance tuning skills.
• Solid grasp of messaging concepts, ideally with Kafka ecosystem experience.
• Exceptional troubleshooting abilities and strong understanding of concurrency principles and security best practices.
• Leadership experience with team mentoring and upper-intermediate English proficiency for stakeholder communication.
