## About the Role

* 12+ years of software engineering experience, depending on quality of scope and impact.
 * Strong backend, platform, infrastructure, distributed systems, or systems engineering foundation.
 * Deep hands-on coding ability; must be able to design, review, debug, and write code regularly.
 * Strong programming knowledge in one or more languages such as Python, Java, Go/Golang, C++, Scala, Kotlin, or C#.
 * Proven experience owning broad, ambiguous technical charters across multiple systems or teams.
 * Strong architecture and system design depth across large-scale production systems.
 * Strong technical judgment across scale, reliability, latency, observability, APIs, data modeling, concurrency, and production operations.
 * Ability to operate as a builder-leader: someone who can define direction, align stakeholders, and still build.
 * Ability to influence and lead without formal authority while staying close to implementation.
 * High intellectual horsepower, fast learning ability, and comfort operating in ambiguity.
 * Strong product/platform judgment and ability to connect technical decisions to business and customer impact.
 * Ability to mentor and elevate engineers across levels.
 * AI/ML background is a strong plus, but not mandatory; practical exposure or strong adjacent experience in AI platform infrastructure, agents, evals, ML/data infra, model infrastructure, inference, sandboxing, workflow automation, scaling, latency, or reliability is highly valuable.

The following would be highly preferable, but not required

 * Prior experience building AI platform infrastructure, eval frameworks, harness systems, LLM tooling, model-quality systems, or ML/data infrastructure.
 * Experience with sandboxing, inference systems, scaling, latency optimization, reliability engineering, or large-scale distributed platforms.
 * Strong Python and SQL knowledge.
 * Experience with Go, Java, C++, or Scala in backend, infra, platform, or distributed systems environments.
 * Experience building internal platforms used by multiple product teams.
 * Prior experience in high-growth / hyper-growth startups or fast-moving product-led technology companies.
 * Exposure to enterprise SaaS, fintech, HR tech, payroll, benefits, compliance, IT, Data Cloud, or workflow-heavy platforms.
