Greenhouse - Platform Engineer

📋 Description

• • A platform builder – you excel at creating tools, infrastructure architectures, and systems that help other engineers move faster and build with confidence.
• • A force multiplier – you think beyond one-off fixes and look for architectural investments that unlock impact across multiple workflows.
• • A reliability-minded engineer – you care about the systemic foundations that make production environments trustworthy, from deployment automation and security to observability and incident response.
• • An AI systems pragmatist – you’re familiar with the potential of agents and automations, but equally focused on the evaluation and telemetry frameworks needed to use them responsibly in workflows.
• • A close partner – you enjoy collaborating directly with engineers to understand engineering workflows, shaping platform interfaces around real-world application needs.
• • WHAT YOU’LL DO
• • Contribute to building and designing the self-service platform that lets stakeholders across Greenhouse build, deploy, and run their own agents and automations against Greenhouse's data and tools.
• • Architect and build self-service infrastructure frameworks that allow application engineers to provision runtime, deployment, and observability stacks independently.
• • Codify and abstract EA's AWS footprint (networking, IAM, secrets) into highly reusable infrastructure-as-code modules or internal APIs.
• • Build and implement the evaluation frameworks and observability practices required to securely run AI systems in production workflows.
• • Evaluate ecosystem needs holistically across the business to spot and execute platform investments that scale across multiple technical teams.
• • Align architectural deliverables with EA's application workflows to ensure the platform integrates cleanly with shipping requirements.
• • At Greenhouse's request, provide technical escalation availability during agreed windows for core platform infrastructure support.
• • YOU SHOULD HAVE
• • 5+ years as a software engineer shipping production services, including building something other engineers actually used: a platform, SDK, framework, internal tool, or API.
• • A proven track record of treating infrastructure as an internal product—building SDKs, frameworks, or developer tools that other engineers rely on daily.
• • Strong Software Engineering fundamentals in Python or TypeScript, with a high degree of comfort designing clean APIs and developer-facing abstractions.
• • Real, hands-on cloud experience. You have operated production services on AWS or GCP end to end (compute, networking, IAM, secrets, deployment automation, Terraform), as the person responsible for an environment, not just a consumer of one.
• • Strong technical instincts regarding the evaluation and telemetry of non-deterministic systems (LLMs/Agents).
• • A developer-experience (DX) mindset: experience gathering engineering feedback on technical specifications, analyzing internal workflows, and iterating on platform design based on system usage data.
• • Production security fundamentals: secrets management, OAuth/OIDC, least-privilege architectures, and dependency hygiene.
