About the Role

This backend-oriented engineering role focuses on integrating AI coding agents deeply into the Air ecosystem. You will influence core business logic, solve problems around context management, tool orchestration, and error recovery, and translate developer interactions into responsive, concurrent technical architectures. You will have full ownership of system design, impacting how millions of developers interact with AI tools.

Responsibilities

  • Design, implement, and develop the core product and business logic for agent-based developer workflows in Air.
  • Build deep integrations between Air product surfaces, external APIs, local CLIs, and AI coding agents.
  • Improve the end-to-end user experience for agents, covering setup, context handling, task execution, and failure recovery.
  • Write highly concurrent and asynchronous logic to manage multi-step agent interactions reliably.
  • Use AI agents and assistants in daily development work to analyze limitations and improve workflows.
  • Write clean, maintainable code, lead technical design discussions, and participate in peer code reviews.
  • Partner with distributed product and ML engineering teams to break down complex architectural problems.

Requirements

  • An engineering mindset that prioritizes long-term system stability and clean architecture over quick patches.
  • The autonomy to drive technical decisions and responsibility for the outcome.
  • A collaborative approach to problem-solving, welcoming direct feedback and technical debate.
  • Curiosity about how AI tools fail in practice and a desire to build systems that gracefully handle those failures.
  • A strong focus on the developer experience, understanding what makes an integration feel seamless or disruptive.
  • Comprehensive experience in professional software development, demonstrating the technical maturity required for senior engineering problems.
  • Strong programming skills in at least one modern backend language, with the readiness to work primarily in Kotlin.
  • A deep practical understanding of concurrent and asynchronous programming, including coroutines, threads, async I/O, and synchronization primitives.
  • A proven track record of building and shipping application workflows, third-party integrations, or service-backed logic.
  • Hands-on experience working with AI-assisted development tools, alongside an understanding of task orchestration, tool usage, and prompt context management.
  • A solid understanding of software engineering fundamentals, including data structures, debugging, observability, and test-driven development.
  • Fluency in written and spoken English for day-to-day technical collaboration across distributed teams.
