Job Description

• Lead and mentor engineering teams, guiding their work and helping unblock technical challenges.
• Own the architecture and design of complex microservice-based applications primarily built in Java and React, with supporting technologies like Kafka, RabbitMQ, PostgreSQL, MongoDB, and Elasticsearch.
• Collaborate closely with product owners to deeply understand the product, the structure of applications, and the business requirements driving changes.
• Ensure the delivery of highly reliable, scalable solutions supporting broadband internet connectivity for high-end private jets - our clients expect flawless, 100% internet coverage in flight.
• Maintain and evolve legacy systems while steering refactoring and new development towards modern, scalable architectures.
• Serve as a key communication point between global teams, particularly as this role transitions responsibilities from teams in India to local ownership.

• Ability to understand and explain complex system architectures and translate business needs into technical requirements.
• Excellent communication skills - comfortable reporting and engaging with senior stakeholders, including direct client interaction at times.
