● Establish engineering culture, values, and best practices.
● Build career frameworks, performance systems, and growth plans.
● Conduct 1:1s, mentor engineers, and drive continuous improvement.
● Set up processes for agile execution, deployments, and incident response.
4. Product & Cross-Functional Collaboration
● Work with the founder and product team on roadmap, feasibility, and prioritization.
● Translate product requirements into technical execution plans.
● Collaborate with design for UX quality and technical alignment.
● Support sales and customer success with integrations and technical discussions.
● Contribute technical inputs to product strategy and customer-facing initiatives.
5. Engineering Operations & Infrastructure
● Own CI/CD, testing frameworks, deployments, and automation.
● Create monitoring, logging, and alerting setups for reliability.
● Manage AWS infrastructure with a focus on cost and performance.
● Build internal tools, documentation, and developer workflows.
● Ensure enterprise-grade security, compliance, and reliability.
