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

Green-card follow-through: 79%

Of 14 labor certifications old enough to have been used, 3 expired without the employer filing the next step. Median time from filing to decision: 494 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

17 transfer filings in the last year, covering 17 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

About the role

  • Set the technical and product direction for a core area of Customer Agent, from architecture through production, and contribute to the direction of the platform overall.
  • Take on the hardest technical problems in your area: orchestration, evaluation, guardrails, memory & context, failure handling for non-deterministic systems.

Responsibilities

  • Write and ship code, review designs, and make the hard calls in your area when there's no obvious right answer.
  • Define patterns that other engineers adopt, and mentor through design reviews rather than direct management.
  • Partner with product, design, data science, and go-to-market leaders to shape what gets built, not just how it's built.
  • Visit klaviyo.com/careers to see how we empower creators to own their own destiny.
  • You're hands-on: writing code, reviewing your own and others' architecture decisions, and debugging production issues yourself, not delegating the hardest problems away.

Requirements

  • You communicate complex technical trade-offs clearly across engineering and product audiences, and you can turn an undefined problem into a plan others rally behind.
  • A track record with production evaluation systems, AI observability, or human-in-the-loop workflows for LLM-powered products.

Skills

  • Evaluate emerging AI technologies and bring the ones worth betting on into production.

Compensation

  • The base salary offered for this position is determined by several factors, including the applicant's job-related skills, relevant experience, education or training, and work location.

Company info

  • Our Engineering team builds the AI systems that power how brands run their businesses on Klaviyo.
  • We move fast, ship in production, and hold a high bar for what "AI-native" actually means: systems that make real judgment calls, not demos.
  • The Customer Agent team is one of the newest and most ambitious groups in that org, based in Boston and working in-office: we're building a conversational AI system that lets brands serve their own customers at a scale no human support team could match.
  • We're still small enough that one engineer's work visibly shapes how the whole platform evolves.
  • We're past the demo stage: the team ships changes against live customer traffic, measures quality with real evaluation frameworks, and treats reliability as a product feature, not an afterthought.
