Employer immigration record

from this employer's Department of Labor filings

Green-card filing pattern in this occupation

Context, not a finding about this posting: of this employer's 4 green-card filings in this occupation, 100% were for a worker who already held the job.

Files H-1B transfers

6 transfer filings in the last year, covering 6 workers. Median labor-condition decision: 44 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • Translate ambiguous product and AI opportunities into clear technical plans, balancing speed, user experience, reliability, safety, and long-term maintainability.
  • Make high-quality technical tradeoffs across product impact, engineering complexity, scalability, and long-term platform health.
  • Mentor and grow engineers across the team, raising the bar for technical execution, product thinking, and engineering culture.

Responsibilities

  • Lead the end-to-end delivery of complex full-stack product experiences, from frontend architecture and backend services to APIs, data integrations, and production workflows.
  • Partner closely with Product, Design, Data Science, Infrastructure, and other engineering teams to bring AI capabilities into real user workflows in a practical, scalable, and measurable way.
  • Build robust systems that connect application logic, data pipelines, model outputs, and human-centered product experiences.
  • Evaluate and integrate AI technologies, including LLM-enabled workflows, retrieval systems, classification, summarization, automation, and decision-support experiences where appropriate.
  • Establish strong frontend and backend engineering standards, including component architecture, API design, system reliability, observability, testing, and development best practices.
  • Drive cross-team and cross-org alignment to ship high-impact work, influencing through technical clarity, judgment, and collaboration rather than authority.
  • A track record of leading the design and delivery of complex consumer or B2B user-facing products across the full stack.

Requirements
