About the role

Hands-on platform engineering role focused on embedding coding agents into Savvy's developer workflow. Own developer and agent experience, build cloud coding interfaces, improve agent output and CI, and drive cross-team standards for safe autonomous coding practices.

Responsibilities

  • Own developer and agent experience: Set the roadmap for how our engineers and coding agents navigate the codebase, use internal tools, run tests, review changes, and ship software.
  • Build the cloud coding experience: Build the developer-facing layer around our existing compute foundations, including task intake, environment setup, context, tools, permissions, observability, review, and delivery.
  • Improve agent output at the source: Change repository structure, interfaces, documentation, instructions, and feedback loops so agents produce correct code and sound architecture more consistently.
  • Engineer context deliberately: Design what agents receive up front, discover progressively, persist, compact, hand off, or discard. Choose models and reasoning effort based on evidence from the job, not habit.
  • Own our internal skills system: Raise the quality of our shared skills and instructions through clear contribution standards, evaluation, discoverability, progressive disclosure, maintenance, and pruning.
  • Fix everyday developer friction: Improve CI speed and reliability, local setup, testing, debugging, deploy workflows, and the other bottlenecks that cost engineers time.
  • Measure what works: Combine developer research and satisfaction data with DORA or SPACE measures and task-level agent evaluations. Inspect traces, establish baselines, and test whether changes improve correctness, reviewability, cost, latency, and human intervention.
  • Drive adoption: Work directly with engineers, teach effective practices, and turn successful experiments into defaults. When the root problem is the codebase or engineering process, make that case and help fix it.
  • Partner on safe autonomy: Work with our infrastructure and security engineers on sandboxing, credentials, approvals, auditability, and the controls needed to give cloud agents useful access without giving them unlimited access.

Qualifications

  • Exceptional with coding agents: You use Claude Code, Codex, Cursor, or similar tools for substantial work and can show how you decompose tasks, manage context, choose models, inspect failures, and consistently produce maintainable software.
  • Internal tools with real users: You have built developer tooling or a platform that engineers beyond your immediate team relied on.
  • CI or large-codebase experience: You have made a meaningful improvement to CI, testing, repository workflows, or developer productivity in a substantial, long-lived codebase.
  • Product judgment for internal systems: You can interview developers, separate symptoms from root causes, turn evidence into a roadmap, and say no to attractive work that will not improve the system.
  • Strong software engineering: You have built and operated substantial production software.
  • Evaluation over intuition: You know agent behavior is nondeterministic and changing quickly. You compare prompts, context, tools, models, and workflows against representative tasks.
  • Cross-team influence: You can set standards and change defaults across teams without becoming a gatekeeper.
  • Pragmatic range: You are comfortable moving between platform code, repository conventions, evaluation data, developer interviews, documentation, and hands-on enablement.
