Cloud Platform - Developer Experience Engineer

Lab37•Pittsburgh, PA

About The Position

Lab37 Robotics is seeking a Cloud Platform - Developer Experience Engineer to take ownership of the developer platform experience that powers how software ships at Lab37. This includes improving CI runner performance and reliability, streamlining the PR landing path, and designing caching strategies that reduce build and test time across a growing monorepo and mixed-language stack. You’ll work with platform and release engineering teams to make builds faster, CI outcomes more predictable, and developer workflows easier to trust. This role is focused on infrastructure and execution quality around CI/CD under Cloud, especially during the transition as services continue to migrate into the cloud monorepo structure.

Requirements

2+ years in Developer Experience, Build/Release Engineering, Platform Engineering, or CI/CD Infrastructure on AWS Cloud
Strong hands-on experience with GitHub (or equivalent CI platform), self-hosted runners, and workflow orchestration patterns
Proven track record reducing CI time and improving pipeline reliability at scale
Deep understanding of caching across modern build systems (Turborepo/Bazel preferred), package ecosystems, and containerized CI
Experience optimizing PR workflows: branch protections, required checks, merge strategies, and developer feedback loops
Strong scripting and automation skills (Python, Bash, or similar) and infrastructure-as-code familiarity (Terraform preferred)
Comfort working across polyglot stacks (web, backend, C++, embedded) and balancing shared platform needs
Strong debugging instincts for non-deterministic CI issues (flaky tests, cache misses, environment drift)

Nice To Haves

Experience with monorepo migrations and CI redesign during repository restructuring
Familiarity with workload right-sizing across runner classes and cost/performance tuning
Experience with Turborepo task graph optimization and remote caching
Experience with Bazel remote execution/caching architecture in multi-language repos
Experience building CI health dashboards and SLOs for engineering productivity
Knowledge of security and compliance checks in CI (for example, secret scanning, policy gates) and performance tuning those checks
Experience with practical patterns for AI-assisted development in CI/CD and DevEx workflows (for example, agent.md definition and infrastructure, build/debug assistance, and PR summarization)

Responsibilities

Design and implement caching strategies across build systems and package managers (for example, Turborepo and Bazel remote/local caching, dependency caching, compiler cache layers)
Own Bazel build performance and reliability in CI, including remote cache strategy, cache hit-rate tuning, and build graph optimization
Own the PR landing experience end-to-end: signal quality, required check ergonomics, merge confidence, and time-to-green optimization
Own the workplace provisioning workflow
Improve CI runner infrastructure (sizing, placement, AMI/toolchain consistency, utilization) to reduce queue times and job duration variability
Build CI observability and reporting for pipeline latency, and cost/performance trends
Partner with teams to identify cost efficient opportunities to streamline the developer experience.
Improve pre-commit and lint pipelines for speed and reliability without lowering enforcement quality
