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 47 green-card filings in this occupation, 100% were for a worker who already held the job.

Green-card follow-through: 78%

Of 18 labor certifications old enough to have been used, 4 expired without the employer filing the next step. Median time from filing to decision: 451 days.100% of their filings were for a worker who already held the job.Only certifications past the 180-day window are counted — recent ones cannot have expired yet.

Files H-1B transfers

83 transfer filings in the last year, covering 83 workers. Median labor-condition decision: 7 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

  • Here, you'll do meaningful work that helps millions of people discover, book, and experience travel with more ease, confidence, and joy.

Responsibilities

  • Design, build, and evolve reliable backend services, including system design (LLD), API design, and data modeling for scalable, secure, and maintainable solutions.
  • Design and ship AI/ML-enabled capabilities in backend services, such as LLM-powered features, agent and tool integrations, and retrieval or automation workflows, with attention to latency, cost, quality evaluation, and failure modes.
  • As a global travel company powered by passionate people, trusted partnerships, and leading technology, we connect travelers, partners, and advertisers through our consumer brands, B2B network, and travel advertising business.
  • Join us and build for travelers everywhere.
  • In this role, you will deliver traveler, partner, and company value with stable architecture, high quality, and operational excellence, and you will help set the bar for how our team uses AI responsibly and effectively.

Requirements

  • Bachelor's degree in Computer Science or a related technical field, or equivalent practical experience.
  • Hands-on, demonstrable proficiency with AI-assisted development: you can describe specific workflows where AI tools measurably improved your speed or quality, and where they failed and how you caught it.

  • Experience with experimentation, feature flags, A/B testing, and analytics to guide technical and product decisions.
  • Experience with LLM application patterns (RAG, tool calling/MCP, agent orchestration), evaluation frameworks, and observability for AI systems (token cost, latency, quality drift).
  • Experience driving AI tooling adoption across a team, including playbooks, shared prompts or agent configurations, and measuring impact.
  • The total cash range for this position in Seattle is $184,500.00 to $258,000.00.
  • Employees in this role have the potential to increase their pay up to $295,000.00, which is the top of the range, based on ongoing, demonstrated, and sustained performance in the role.
