Align your resume to Klaviyo's stack
Klaviyo's engineering roles consistently emphasize distributed systems, Python, and data pipeline experience. Tailor your resume to reflect these before applying so your credentials map directly to what their technical screens prioritize.
Target roles before H-1B cap season
USCIS opens H-1B registration in March for an October 1 start date. Timing your application to Klaviyo in Q4 or Q1 gives you the best chance of receiving an offer early enough to be included in that filing cycle.
Confirm sponsorship willingness before technical rounds
Klaviyo's recruiter screens are the right moment to ask whether the specific role is approved for H-1B sponsorship. Some headcount is added mid-year and may carry different approval status, so surface this before investing time in system design interviews.
Understand what the LCA filing means for your offer
Before USCIS approves your H-1B petition, your employer files a Labor Condition Application with DOL certifying your wage meets the prevailing rate. Review the certified LCA carefully since the wage level stated there becomes the floor for your compensation.
Use Migrate Mate to surface Klaviyo's open roles
Sponsored Software Engineer roles at Klaviyo aren't always flagged clearly on general job boards. Use Migrate Mate to filter specifically for Klaviyo positions that support visa sponsorship so you're not applying blind to roles that won't move forward.
Build toward EB-2 eligibility through your role scope
If you're targeting permanent residence through Klaviyo, the PERM process requires demonstrating a specific minimum requirement for the role. Document responsibilities that justify an advanced degree requirement from day one, as this shapes the labor certification later.

Find Software Engineer at Klaviyo JobsFrequently Asked Questions
Does Klaviyo sponsor H-1B visas for Software Engineers?
Yes, Klaviyo sponsors H-1B visas for Software Engineer roles. The company has an established pattern of filing H-1B petitions for engineering hires, which means sponsorship is part of their standard recruiting process rather than a case-by-case exception. You should confirm sponsorship availability for a specific role during the recruiter screen, as not every open position carries approval for new sponsorship.
Which visa types does Klaviyo commonly use for Software Engineers?
Klaviyo primarily uses the H-1B visa for Software Engineers entering the U.S. on a nonimmigrant work visa. For employees pursuing permanent residence, the company supports employment-based Green Card pathways including EB-2 and EB-3 categories, which require PERM labor certification filed through the Department of Labor before an immigrant petition can proceed with USCIS.
How do I apply for Software Engineer jobs at Klaviyo?
Applications go through Klaviyo's careers page, where roles are listed by team and level. The process typically includes a recruiter screen, a technical phone interview covering data structures and algorithms, and a virtual onsite with system design and coding components. Klaviyo's engineering teams are product-oriented, so demonstrating an understanding of how backend systems connect to customer-facing outcomes strengthens your candidacy beyond raw coding ability.
What qualifications does Klaviyo expect for Software Engineer roles?
Most Software Engineer roles at Klaviyo require a bachelor's degree or higher in computer science, software engineering, or a closely related field, which also satisfies the specialty occupation requirement for H-1B sponsorship. Practically, Klaviyo screens for proficiency in Python or similar backend languages, experience with distributed systems or data pipelines, and the ability to own projects end-to-end rather than work in narrow feature lanes.
How do I find Software Engineer roles at Klaviyo that sponsor visas?
General job boards don't always surface which Klaviyo roles include visa sponsorship. Migrate Mate lets you browse Software Engineer openings at Klaviyo filtered by sponsorship type, so you can identify positions that support H-1B or Green Card pathways before starting the application process. This saves time you'd otherwise spend applying to roles that aren't approved for new sponsorship filings.
