• You understand key frontend performance metrics and have some experience in debugging frameworks such as Lighthouse and ChromeUX.
• Exert technical influence over multiple teams, actively mentor individuals on advanced technical issues, and help technology managers guide the technical growth of their team members.
• Support Product and Delivery in building highly scalable solutions aligned with non-functional requirements in terms of performance, security & regulatory.
• Provide clear hands-on solutions with POCs or actual implementations depending on the particular case and scenario.
• Participate in technical discussions as part of the team. You should be ready to challenge our architecture, propose changes, and ultimately implement them.
• Become the first point of contact between the Architecture Engineering Team and Development Teams. Safeguard our engineering processes and the way we deliver software to browsers and mobile devices.

Just greenfield builds, modern tech, and real ownership from day one. 

We move fast, think lean, and execute with focus, one product at a time, full commitment, full impact. Every sprint matter, every decision ship value. This is not a support team. It’s a build-from-scratch engine for products that matter, because every hero needs a superhero.

• Set up and drive real-time data capabilities using Apache Kafka, enabling new products to process and react to business-critical data streams from day one.
• Establish consistent, scalable configuration management practices across services and environments, ensuring every new product starts with a solid foundation.
• Implement observability as a core feature - building logging, monitoring, and alerting systems that provide immediate insight and support rapid decision-making.
• Continuously improve delivery speed, system reliability, and developer experience, removing friction and enabling teams to move from idea to production with minimal overhead.
• Collaborate closely with product and engineering teams during early-stage builds, shaping infrastructure and platform decisions that directly impact product success.

Employees may be required to participate in an on-call rotation, ensuring availability outside regular working hours to respond to urgent issues as needed as per the On call policy.

Who You Are:

• Technical Expertise: Proficient in Docker, Kubernetes, Terraform, Packer, and Ansible. 
• CI/CD Knowledge: Solid understanding of CI/CD processes and tools, including Git, Jenkins, and Microsoft Teams.
