Build and evolve developer-facing platforms and SDKs, focusing on usability and performance

Provide technical leadership and mentorship to engineers across the team

Collaborate cross-functionally to deliver high-impact, business-critical features

Drive best practices in code quality, testing, and system design

Troubleshoot complex production issues and guide teams toward long-term solutions

What We’re Looking For:

Deep expertise in Java and Spring Boot; experience with Python or Go is a plus

Strong background in large-scale distributed systems and event-driven architectures

Expertise in REST, gRPC, and asynchronous messaging systems (Kafka, RabbitMQ, etc.)

Proven experience designing cloud-native architectures and working with modern CI/CD pipelines

Demonstrated ability to lead technical initiatives and influence engineering direction

Strong problem-solving skills with a pragmatic, scalable mindset

Experience in startup environments or building new teams/products from the ground up
