Lead Infrastructure Engineer - Developer Experience

5+ years of relevant experience in software engineering, developer tooling, SDLC, or observability.

You have owned and operated systems such as CI/CD infrastructure, source control platforms, observability tooling, or developer automation.

Languages in our ecosystem include Python, Java, Go, and Bash.

Experience with AI/LLM-based developer tools (coding agents, AI-assisted code review, retrieval-augmented generation), AI-ecosystem infrastructure, and self-hosted models is highly valued.

Ability to balance delivery with correctness, delivering timely solutions that are properly risk-managed for the needs of the business

In some cases, you may also be contacted by independent search firms engaged to recruit on our behalf; emails from their employees should always come from their firm's applicable domain.

Arcesium seeks an accomplished Lead Engineer to join the Developer Experience (DevEx) team, part of our Infrastructure organization.

You have a low tolerance for friction in the development loop.

Slow CI pipelines, flaky tests, observability that leaves you guessing, deploy processes that make people hold their breath — these are the things that nag at you, and you channel that into building practical solutions that measurably improve developer velocity and satisfaction.

DevEx’s mandate is to maximize developer productivity and efficacy by providing best-in-class SDLC and Observability services, and by building systems that strategically apply GenAI to every stage of software development and operations.

As a Lead Engineer on the DevEx team, you will own one or more subsystems or services across areas, delivering high-quality products both individually and collaboratively.

In this role you will lead by example through your strong engineering skills, supported by the quality of the software you build, the insightful code reviews you provide to others, and the technical solutions you originate and implement.
