Why this role exists:
This role exists to architect and ship the high-performance backbone of our platforms. You’ll help us achieve global scalability by owning the end-to-end delivery of resilient Java-based microservices and mentoring the next generation of engineering talent.
What you’ll drive:
Architecture & Technical Decisions
- Design and evolve scalable microservices using Java 17+ and Spring Boot.
- Apply resilience patterns (Circuit Breaker, Bulkhead, Rate Limiting) to ensure systems thrive under pressure.
- Evaluate and select database strategies (PostgreSQL, NoSQL, Redis) based on specific performance trade-offs.
- Design event-driven architectures utilizing Kafka or RabbitMQ to handle real-time data flow.
Delivery & Execution
- Own the full development lifecycle—from initial requirement elicitation to production release.
- Ship clean, maintainable, and highly efficient code that sets the standard for the team.
- Optimize application performance by profiling JVM internals and fine-tuning garbage collection.
- Unblock the release pipeline by automating testing and improving CI/CD workflows in GitLab.
Quality & Reliability
- Enforce "Security by Design" and secure coding practices (OWASP Top 10) across all services.
- Drive continuous improvement in testing protocols, including integration, performance, and BDD.
- Identify and resolve complex production bottlenecks using monitoring tools like ELK or Datadog.
- Maintain comprehensive technical documentation that simplifies complex system designs for others.
Team Growth & Leadership
- Mentor junior and middle engineers through high-quality code reviews and technical guidance.
- Partner with Product Managers and Delivery Managers to align technical roadmaps with business outcomes.
- Foster an Agile culture by actively participating in planning, estimation, and iterative delivery.
