Get Access To All JobsJob Title: Python Full stack Lead
Location: Los Angeles, CA
High Priority need profiles ASAP.
We are seeking a Python Fullstack Lead with deep expertise in Python, distributed systems, cloud-native architecture, and microservices. The candidate must have in-depth expertise in at least one major cloud platform — AWS, Azure, or GCP and the ability to translate business requirements into scalable, resilient, secure, and production-ready architectures. The candidate should also have hands-on experience with React and TypeScript to guide front-end architecture and its integration with backend services.
Key Responsibilities
- Must have 3 years retail or e-commerce experience.
- Design cloud-native microservices using Python, applying Domain-Driven Design (DDD), appropriate service boundaries, and loosely coupled architectures.
- Define HLD/LLD, API contracts, service interactions, data ownership, integration patterns, and architecture standards.
- Design REST/gRPC APIs, API gateways, authentication/authorization, versioning, rate limiting, idempotency, and backward compatibility.
- Design event-driven and asynchronous architectures using Kafka or cloud-native messaging services; address ordering, retries, duplicate messages, DLQs, replay, and eventual consistency.
- Apply distributed-systems patterns including Saga, CQRS, Outbox, Circuit Breaker, Retry/Backoff, Bulkhead, and distributed caching.
- Design highly available and scalable solutions using Docker, Kubernetes, serverless and managed cloud services.
- Ensure application and infrastructure security using IAM/RBAC, OAuth2/OIDC, JWT, mTLS, secrets management, encryption.
- Define front-end architecture standards for React and TypeScript applications, including component design, state management, and integration with backend microservices via REST/GraphQL APIs or Backend-for-Frontend (BFF) layers.
- Ideal candidate should have worked on an eCommerce domain and have basic ideas on composable package components in eCommerce like headless CMS, headless search etc and have hands-on experience integrating them via backend services.
Technical Requirements
- Python 3.x, FastAPI/Flask/Django, asyncio, concurrency, type hints, testing, profiling and performance optimization.
- Hands-on experience with React and TypeScript, including hooks, state management (e.g., Redux, React Query), component-based architecture, front-end performance optimization, and testing.
- Expert-level knowledge of AWS OR Azure OR GCP (AWS will be preferred), including compute, containers/Kubernetes, API Gateways, networking, IAM/security, databases, messaging, storage, monitoring and serverless capabilities.
- Strong understanding of designing and implementing event driven architecture using a cloud provider leveraging patterns like fan out (Eventbridge, SNS, SQS / Kinesis in case of AWS) with proper message/data redundancy and fall back mechanisms.
- Strong SQL and database design skills with PostgreSQL/MySQL/Oracle plus experience with NoSQL technologies such as DynamoDB, MongoDB, Cosmos DB, Cassandra or equivalent.
- Experience working with AI tools would be a plus.
- Experience with retail/e-commerce, high-volume transaction processing, multi-region architectures.
- Strong understanding of system design, distributed systems, scalability, resilience, security and production operations.

Get Access To All JobsTips for Finding Visa Sponsorship as a Senior Python Engineer
Target companies with H-1B filing history
Not every employer sponsors visas, even for in-demand engineering roles. Focus your search on companies with a documented history of H-1B filings for software engineering positions. Migrate Mate filters for sponsors so you skip the guesswork.
Confirm your degree field matches the role
H-1B approval for Senior Python Engineers typically requires a bachelor's degree or higher in computer science, software engineering, or a closely related field. A degree in an unrelated discipline can complicate specialty occupation classification, even with strong experience.
Senior titles strengthen your H-1B case
USCIS scrutinizes whether a role genuinely requires a specialized degree. Senior-level job titles with defined technical scope, architecture responsibilities, or team leadership duties make the specialty occupation argument significantly cleaner than junior or generalist engineering titles.
O-1A is a real alternative if you have a strong track record
If you've led notable open-source projects, published technical work, or received industry recognition, the O-1A visa may be within reach. It has no lottery, no annual cap, and can be employer-sponsored or self-petitioned through an agent.
Negotiate premium processing into your offer
Standard H-1B processing can take three to six months. Premium processing guarantees an adjudication decision within 15 business days for an additional USCIS fee. Ask whether the employer covers premium processing before accepting an offer that requires status change.
L-1B is an option if you're transferring within a multinational
Senior Python Engineers at multinationals with a U.S. presence may qualify for an L-1B intracompany transfer based on specialized knowledge. This bypasses the H-1B lottery entirely and is particularly useful if you've worked for the company abroad for at least one year.
Frequently Asked Questions
Does a Senior Python Engineer role qualify as an H-1B specialty occupation?
Yes, in the vast majority of cases. USCIS considers software engineering roles specialty occupations when the position normally requires at least a bachelor's degree in computer science, software engineering, or a directly related field. Senior-level roles with defined technical scope are generally stronger candidates than generalist or entry-level titles, since the complexity of duties makes the degree requirement easier to substantiate in the petition.
What visa types do employers typically sponsor for Senior Python Engineers?
H-1B visa is the most common path, but far from the only one. L-1B covers intracompany transfers for engineers with specialized knowledge. O-1A applies to those with a strong track record of recognition or contribution in their field. Some employers also sponsor TN visas for Canadian and Mexican nationals, and E-3 visas for Australian citizens. The right visa depends on your nationality, current status, and the employer's willingness to sponsor.
How can I find Senior Python Engineer jobs that offer visa sponsorship on Migrate Mate?
Migrate Mate is built specifically for this. Every job on the platform is filtered for visa sponsorship, so you're not wasting time applying to roles that won't support your immigration status. Browse Senior Python Engineer listings on Migrate Mate to find employers who have an active history of sponsoring work visas for engineering roles.
What if my degree isn't in computer science, can I still get H-1B sponsorship as a Python engineer?
Possibly, but it adds complexity. USCIS allows degrees in related fields like mathematics, information systems, or electrical engineering to support a software engineering petition. If your degree is in an unrelated field, your employer's attorney will need to build a stronger case using a combination of your education and progressive work experience. A credential evaluation and detailed job duty analysis both help.
What are H-1B approval rates for software engineering roles, and how does seniority affect outcomes?
USCIS has historically approved software engineering H-1B petitions at high rates compared to more contested categories. Seniority genuinely helps: roles with senior, lead, or principal titles carry more defined technical responsibilities, which makes it easier to satisfy the specialty occupation standard. Roles that look generalist or interchangeable regardless of title face higher rates of Requests for Evidence. Employers with established immigration programs and experienced counsel tend to see stronger outcomes.
What is the prevailing wage requirement for sponsored Senior Python Engineer jobs?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
