Align your stack with Affirm's core systems
Affirm's fullstack engineering work spans React frontends and Python or Kotlin backends tied to payment processing and risk infrastructure. Framing your resume around financial systems, transactional data handling, or API design will signal direct role fit before you apply.
Confirm H-1B readiness before accepting interviews
Affirm sponsors H-1B visas for senior engineering roles, but cap-subject petitions must be filed in April for an October start. If your OPT expires before October, clarify upfront whether the team can accommodate a gap or has filed cap-exempt petitions through affiliated entities.
Use Migrate Mate to surface open roles efficiently
Senior Fullstack Software Engineer positions at Affirm span multiple product areas and open on a rolling basis. Use Migrate Mate to filter Affirm's active listings by visa type so you're applying to roles where sponsorship is already confirmed rather than asking after the fact.
Request LCA wage level details before the offer stage
Affirm files Labor Condition Applications with DOL that lock in a prevailing wage level for your role and location. Wage Level III versus Level IV affects both your base offer and future Green Card timelines under EB-2 or EB-3, so it's worth understanding before you negotiate.
Prepare for behavioral interviews grounded in scale
Affirm's senior engineering bar emphasizes ownership of high-availability systems and cross-functional delivery in regulated financial environments. Prepare concrete examples of technical decisions you made under compliance or latency constraints, not just generic architecture stories.
Understand TN eligibility if you hold Canadian or Mexican citizenship
Software engineers from Canada or Mexico can enter on TN status under USMCA without waiting for H-1B lottery results. Affirm sponsors TN visas for qualifying roles, and TN processing at the border can result in same-day authorization, which compresses the hiring timeline significantly.
Frequently Asked Questions
Does Affirm sponsor H-1B visas for Senior Fullstack Software Engineers?
Yes, Affirm sponsors H-1B visas for Senior Fullstack Software Engineer roles. The company has an active track record of filing petitions across multiple engineering functions, including fullstack positions. If you're subject to the H-1B cap, timing matters: petitions must be filed in April for an October 1 start date, so aligning your offer timeline with Affirm's recruiting cycle is essential.
How do I apply for Senior Fullstack Software Engineer jobs at Affirm?
Applications go through Affirm's careers portal, where roles are listed by team and location. Many positions are open to remote candidates in specific U.S. states. To find Senior Fullstack Software Engineer openings at Affirm filtered by visa sponsorship availability, Migrate Mate aggregates these listings so you can confirm sponsorship eligibility before reaching out to a recruiter.
Which visa types does Affirm commonly sponsor for Senior Fullstack Software Engineers?
Affirm sponsors H-1B, TN visa, and F-1 OPT and CPT for engineering roles, along with immigrant visa categories including EB-2 and EB-3 for longer-term employment. H-1B is the most common path for international engineers without Canadian or Mexican citizenship. TN visa is a strong alternative for Canadian and Mexican nationals given its faster processing and no lottery requirement.
What qualifications does Affirm expect for Senior Fullstack Software Engineers?
Affirm's senior engineering bar typically requires several years of experience building production systems across both frontend and backend layers. The company values depth in at least one modern frontend framework alongside backend proficiency in Python, Kotlin, or a comparable language. Experience with high-availability, distributed systems in a regulated or financial services context carries particular weight at the senior level.
How do I time my application around H-1B filing deadlines if I'm on OPT?
USCIS opens H-1B registration in March, with cap-subject petitions filed in April for an October 1 start. If your OPT runs out before October, your 60-day grace period and any STEM OPT extension you've already filed can bridge the gap. Securing an offer by February or March gives Affirm time to prepare your petition before the registration window opens.
