Responsibilities

  • Own the roadmap for developer and coding-agent interaction with codebases, internal tools, testing, review, and software delivery.
  • Build the developer-facing cloud coding layer covering task intake, environment setup, context, tools, permissions, observability, review, and delivery.
  • Improve agent-generated code and architecture through repository structure, interfaces, documentation, instructions, feedback loops, and context design.
  • Own the internal skills and instructions system, including contribution standards, evaluation, discoverability, maintenance, and pruning.
  • Improve CI, local development, testing, debugging, deployment workflows, and other developer productivity bottlenecks.
  • Measure correctness, reviewability, cost, latency, and human intervention using developer research, satisfaction data, DORA, SPACE, traces, and task-level evaluations.

Requirements

  • Ability to interview developers, identify root causes, create evidence-based roadmaps, and make product judgments for internal systems.
  • Strong software engineering experience building and operating substantial production software and implementing durable solutions independently.
  • Experience evaluating nondeterministic agent behavior by comparing prompts, context, tools, models, and workflows against representative tasks.
  • Ability to set standards and change defaults across teams through evidence-based cross-team influence.
  • Pragmatic range across platform code, repository conventions, evaluation data, developer interviews, documentation, and hands-on enablement.
  • Preferred experience with cloud or remote development environments, coding-agent control planes, secure execution sandboxes, agentic code review, agent tools and orchestration, model-routing infrastructure, DORA or SPACE, or security- and compliance-sensitive industries.
