Staff Software Engineer - DevX

Amplitude is an AI-first digital analytics platform that helps companies build better products and digital experiences. The Staff Software Engineer will set the architecture for the developer platform, lead software factory initiatives, and accelerate cloud-first development workflows through infrastructure, tooling, and technical leadership.

Responsibilities:

• Cloud development platform: Unify and scale our existing local, remote, and ephemeral development environments across a polyglot codebase. Make it fast and reliable for engineers and AI agents to provision environments, build, test, debug, and validate changes, with reproducible test data and clear access controls
• Software factory: Find the biggest bottleneck in the engineering workflow, automate it, then move to the next one. This increasingly means building the sandboxes and tooling that let AI agents do the work directly, not just assist with it
• Developer experience & tooling: Own build systems, CI/CD, developer environments, and internal tooling. Drive down build/CI time, deploy risk, and feedback latency
• Technical leadership: Set direction and standards, turn ambiguous problems into roadmaps, and mentor senior/staff engineers through design review and pairing

Requirements:

• Staff-level engineering experience and impact
• Full-stack, infra-leaning skills, strong on the backend and systems side
• Experience moving a team's development workflow into the cloud (VMs, remote environments, preview branches, sandboxes)
• A track record of shipping developer tooling or platform infrastructure that measurably improved velocity
• Hands-on experience building agentic or AI-powered engineering workflows, used responsibly with human oversight
• Strong judgment, clear writing, and the ability to drive alignment without formal authority
• Monorepo tooling or large-scale platform migrations
• Agent harness infrastructure: eval frameworks, orchestration, or sandboxing for LLMs
