Get Access To All JobsTips for Finding Product Software Engineer Jobs at Klaviyo Jobs
Align your portfolio with Klaviyo's product surface
Klaviyo's engineering work centers on data pipelines, event-driven architecture, and developer-facing APIs. Projects that demonstrate experience with high-throughput systems or SaaS product development will resonate more than generic full-stack work when your application is reviewed.
Ask about immigration counsel during the offer stage
Klaviyo works with outside immigration attorneys for sponsored roles. During offer negotiations, ask whether they retain dedicated counsel and what the typical timeline looks like from offer acceptance to petition filing. This signals you understand the process and surfaces any internal delays early.
Use Migrate Mate to filter Product Software Engineer openings
Not every Klaviyo job listing specifies sponsorship eligibility upfront. Use Migrate Mate to surface verified Product Software Engineer roles at Klaviyo that are open to sponsored candidates, saving you from applying to postings that won't move forward for visa holders.
Prepare for EB-2 or EB-3 PERM documentation early
If Klaviyo sponsors your green card through PERM, DOL requires documentation of your qualifications matching the job description exactly. Start compiling degree transcripts, employment letters, and any credential evaluations for foreign degrees before the process begins to avoid delays.
Target Klaviyo's product engineering teams directly
Klaviyo structures hiring around specific product areas such as integrations, analytics, and platform reliability. Identifying which team your background fits and referencing that in your application increases the chance your profile reaches a hiring manager who can champion sponsorship internally.

Find Product Software Engineer at Klaviyo JobsFrequently Asked Questions
Does Klaviyo sponsor H-1B visas for Product Software Engineers?
Yes, Klaviyo sponsors H-1B visas for Product Software Engineers. The company has a consistent pattern of filing H-1B petitions for engineering roles, and sponsorship is a documented part of their hiring for this function. If you're in the H-1B cap lottery cycle, confirm your timeline aligns with Klaviyo's offer process before the March registration window closes.
How do I apply for Product Software Engineer jobs at Klaviyo?
Applications go through Klaviyo's careers page, where roles are listed by team and level. Before applying, use Migrate Mate to identify which current Product Software Engineer openings are open to visa sponsorship. Tailor your application to the specific product area you're targeting, since Klaviyo's engineering org is structured around distinct product surfaces with separate hiring pipelines.
Which visa types does Klaviyo commonly sponsor for Product Software Engineers?
Klaviyo sponsors H-1B visas for cap-subject candidates and also supports employment-based Green Card pathways, primarily through EB-2 and EB-3 classifications via the PERM labor certification process. Engineers already on L-1 or O-1 status may also be accommodated, but H-1B is the most common entry point for new hires requiring sponsorship.
What qualifications does Klaviyo expect for Product Software Engineer roles?
Klaviyo typically looks for engineers with experience building SaaS products at scale, with strong fundamentals in backend systems, APIs, or data-intensive architecture. A bachelor's degree in computer science or a related field is standard for H-1B specialty occupation eligibility. Roles often require demonstrated ownership of product features end-to-end, not just implementation work on isolated tickets.
How do I plan my timeline if I need H-1B sponsorship at Klaviyo?
H-1B cap-subject petitions must be filed in April for an October 1 start date, following a March lottery registration. If you receive an offer from Klaviyo outside that window, they may be able to support an H-1B extension or transfer if you're already sponsored elsewhere. OPT and STEM OPT extensions can bridge the gap while USCIS processes your petition.
