ROLE
The Fraud Experience team builds intelligent, real-time systems that safeguard Whatnot’s marketplace from malicious activity. We design, develop, and deploy end-to-end, ML-driven systems that proactively identify and mitigate fraud — blending real-time detection with transparent, user-centered enforcement.
- Lead the full architecture of fraud detection, prevention, and intervention systems — spanning machine learning, backend, and client-side components.
- Build intelligent user graphs to model behavioral patterns, detect collusion networks, and uncover account connectivity at scale.
- Design, train, and deploy both traditional ML and LLM-powered models to detect fraudulent activity across users, payments, and marketplace interactions.
- Develop scalable data pipelines and real-time inference systems capable of supporting high-volume, low-latency ML workloads.
- Create human-in-the-loop systems that continuously refine detection accuracy and adapt to evolving adversarial tactics.
- Perform deep behavioral and adversarial data analysis to surface emerging fraud trends and drive continuous system improvement.
- Stay ahead of the curve by translating new insights into adaptive, production-ready systems that evolve as fast as our adversaries.
We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our Los Angeles, New York, San Francisco or Seattle hub.

Get Access To All JobsTips for Finding Software Engineer AI Jobs at Whatnot
Frame your ML work around commerce outcomes
Whatnot's AI engineering work is tied directly to live marketplace performance, not pure research. Tailor your portfolio to show recommendation systems, fraud detection, or real-time ranking models with measurable business impact, not academic benchmarks.
Verify your OPT timeline before applying
F-1 OPT gives you 12 months of work authorization, with a 24-month STEM extension if your degree qualifies. Confirm your program's CIP code with your DSO before targeting roles, since a misaligned field can block the extension entirely.
Target roles that align with your specialty occupation
USCIS requires H-1B positions to qualify as specialty occupations requiring a bachelor's degree or higher in a specific field. Software Engineer AI roles at a live commerce platform like Whatnot typically satisfy this, but your degree field should connect directly to the ML or systems work in the job description.
Use Migrate Mate to filter Whatnot's open AI roles
Whatnot posts Software Engineer AI positions across different seniority levels and ML sub-disciplines. Use Migrate Mate to filter specifically for Whatnot's open roles by visa type so you're applying to positions where sponsorship is already confirmed, not assumed.
Raise sponsorship early in recruiter conversations
Whatnot moves quickly in its hiring process. Surface your visa status in the initial recruiter screen rather than waiting for an offer, so the team can loop in HR and legal before you reach final rounds and timeline conflicts emerge.
Understand the H-1B cap and Whatnot's filing window
Cap-subject H-1B petitions must be filed in April for an October 1 start date. If you receive an offer outside that window, ask whether a cap-exempt bridge arrangement or change of status from OPT is possible to cover the gap.
Frequently Asked Questions
Does Whatnot sponsor H-1B visas for Software Engineer AIs?
Yes, Whatnot sponsors H-1B visas for Software Engineer AI roles. The company has an established pattern of supporting work visa petitions for engineering functions, including AI and machine learning positions. If you're cap-subject, timing your application to align with Whatnot's hiring cycles and the April H-1B filing window is essential.
How do I apply for Software Engineer AI jobs at Whatnot?
Apply directly through Whatnot's careers page or browse their open Software Engineer AI roles on Migrate Mate, which filters specifically for positions where visa sponsorship is available. Before applying, confirm your visa status with a recruiter early in the process. Whatnot typically runs a technical screen, followed by system design and ML-focused interview rounds.
Which visa types does Whatnot support for Software Engineer AI roles?
Whatnot sponsors a range of visa categories for Software Engineer AI positions, including H-1B, E-3 visa (for Australian citizens), TN visa (for Canadian and Mexican nationals), F-1 OPT and CPT, J-1 visa, and employment-based Green Card pathways including EB-2 and EB-3. The right category depends on your nationality, degree, and career stage.
What qualifications does Whatnot expect for Software Engineer AI roles?
Whatnot's Software Engineer AI roles generally require a bachelor's degree or higher in computer science, machine learning, or a closely related field. Practical experience with recommendation systems, real-time ML pipelines, or large-scale data infrastructure is valued given the live commerce context. Strong Python and systems design skills are consistently expected across seniority levels.
How do timelines work for visa sponsorship at Whatnot for this role?
Timeline depends on your visa type. F-1 OPT can authorize work quickly once your employment start date is confirmed with your DSO. H-1B cap-subject petitions follow a fixed annual cycle with an October 1 start date. TN and E-3 visas can often be processed faster, sometimes within weeks. Discuss your specific situation with Whatnot's HR team at the offer stage so USCIS or consular processing deadlines don't create gaps in your start date.
