Full description
At GBL Tech, we drive high-impact technology careers through specialization and scale. We operate across critical digital ecosystems - from Fintech to Smart Industry - connecting talent with technically challenging projects and modern stacks.
The Role:
We are looking for a Senior Java Engineer who is ready to move beyond just shipping tickets. You will join a strategic project for one of our key clients, acting as a technical anchor for their core backend services and bridging the gap between raw code and real-world business impact. At this level, you won't just follow a roadmap-you will help draft it. You will own outcomes, champion simplicity, and ensure that the systems you build don't just work, but thrive under global scale.
What You’ll Be Doing
- Architecture as a Craft: Design for high availability, ensuring that monitoring, logging, and graceful degradation are built into the DNA of every feature. You aim for the "elegant simplest solution" rather than over-engineering.
- Technical Compass: Act as the team’s compass, prioritizing high-value features and translating technical trade-offs - such as cost, risk, and speed - into terms that the client's stakeholders truly care about.
- Cultivating Excellence: Multiply your impact by mentoring teammates, conducting detailed code reviews, and fostering a "security-by-design" culture within the client's engineering team.
What We Are Looking For
- 5+ years of experience with Java and cloud-native architectures (preferably AWS).
- Deep expertise in Spring Boot and related Java frameworks, with a track record of building scalable backend services.
- Solid hands-on experience with both Relational (RDBMS) and Non-Relational (NoSQL) databases. You know when to choose the right tool for the data structure and access pattern.
- You are a self-starter who thrives in dynamic environments; you define problems when they are unclear and make timely, well-founded decisions.
- You proactively build relationships across teams and navigate complex technical or interpersonal discussions with ease and diplomacy.
- Good knowledge of english is mandatory.
