Applied AI/LLM Focus
- Build and productionalize LLM-enabled features (e.g., workflow automation, intelligent routing, summarization, extraction)
- Design tool/function-calling services and orchestration layers for multi-step tasks
- Implement RAG-style retrieval patterns (embeddings, vector search, ranking) where it improves reliability and accuracy
- Develop evaluation and quality frameworks for AI outputs (offline evals, regression tests, safety/reliability checks)
- Collaborate on responsible AI practices: guardrails, data handling, deterministic behaviors, and auditability
What you will bring:
- BA/BS in Computer Science or a related field, or equivalent practical experience
- 5+ years of professional Python development experience in production environments
- Strong experience building asynchronous, API-driven microservices (e.g., FastAPI, asyncio)
- Solid understanding of scalable backend architectures and service-to-service integrations
- Experience with distributed systems patterns (queues, caching, pub/sub, background processing)
- Strong understanding of REST APIs, authentication/authorization, and secure system design
- Experience with CI/CD pipelines and containerized deployment workflows
- Strong familiarity with Git and modern version control workflows
- Excellent English communication skills, both written and verbal
- Ability to work effectively in cross-functional, fast-paced environments
Preferred Qualifications:
- Experience integrating LLM APIs in production and building robust, testable AI-enabled services
- Familiarity with prompt design, structured outputs, tool/function calling, and conversation/workflow state management
- Experience with embeddings, vector databases, retrieval pipelines, and/or ranking approaches
- Experience building AI evaluation harnesses (golden datasets, regression testing, quality metrics)
- Exposure to ML concepts relevant to applied product systems (classification, extraction, ranking, personalization)
- Experience with real-time or conversational interfaces (chat and/or voice) and streaming systems
- Proficiency in Spanish (or other major marketplace languages) to help evaluate and validate multilingual AI outputs
- Experience supporting high-traffic, consumer-facing applications
Why You’ll Love Working Here

Get Access To All JobsTips for Finding E-3 Visa Sponsorship as a Python Engineer
Translate your Australian degree for U.S. employers
A three-year Australian bachelor's in computer science or software engineering meets the E-3 specialty occupation requirement. Carry your official transcripts and be ready to explain degree equivalency if an employer's HR team is unfamiliar with the Australian system.
Target companies with active LCA filing history
Search the DOL's Office of Foreign Labor Certification disclosure data to identify employers who have filed Labor Condition Applications for Python or software engineering roles. Prior LCA filings signal that a company already understands the E-3 process.
Find E-3-ready Python roles through Migrate Mate
Use Migrate Mate's E-3 filing service to search Python Engineer roles filtered by employers with E-3 sponsorship history, then manage your LCA filing and consulate paperwork through the same platform.
Clarify job titles before the LCA is filed
The DOL classifies Python roles under multiple Standard Occupational Classification codes, including software developer and software quality assurance. Confirm with your employer which SOC code matches your actual duties before the LCA is submitted, since this affects prevailing wage requirements.
Address contract and consulting roles early in negotiations
E-3 sponsorship requires a bona fide employer-employee relationship. If you're placed at a third-party client site through a staffing firm, USCIS scrutinizes whether the sponsoring employer controls your day-to-day work. Clarify this structure before accepting an offer.
Book your consulate appointment before giving notice
E-3 visas are issued at Australian consulates, not through USCIS. Sydney, Melbourne, and Perth appointments can book out several weeks. Secure your appointment date before resigning from your current role so you have a confirmed timeline.
Python Engineer jobs are hiring across the US. Find yours.
Find Python Engineer JobsPython Engineer E-3 Visa: Frequently Asked Questions
How do I find Python Engineer jobs with E-3 visa sponsorship?
Migrate Mate is built specifically for this search. It filters Python Engineer roles by employers with E-3 sponsorship history, so you're not cold-applying to companies that have never filed an LCA. You can also use Migrate Mate's E-3 filing service once you have an offer, handling the entire process from LCA through your consulate appointment.
How much does it cost to get an E-3 visa?
Migrate Mate's E-3 filing service covers the entire process for $499, including the Labor Condition Application, visa document preparation, and consulate appointment guidance. Traditional immigration lawyers charge $2,000–$5,000+ for the same work. The E-3 has less paperwork than most work visas, so paying thousands for legal help is usually unnecessary.
Does a Python Engineer role qualify as a specialty occupation for the E-3?
Yes, in most cases. The E-3 requires that the position normally requires at least a bachelor's degree in a directly related field, such as computer science, software engineering, or information systems. A generic Python developer role at a startup that lists a degree as preferred rather than required can create problems, so reviewing the job description before applying matters.
How does the E-3 compare to the H-1B for Python Engineers?
For Australian citizens, the E-3 is significantly more practical. There is no annual lottery, no cap backlog, and applications are processed at Australian consulates rather than through USCIS's multi-month adjudication timeline. The H-1B has an 85,000-slot annual cap with a registration lottery, meaning a qualified Python Engineer can wait years before getting selected.
Can I change employers or Python Engineer roles while on an E-3?
Yes, but you need a new LCA and a new visa stamp for each employer change. You can start working for the new employer once the DOL certifies the new LCA and you have a valid E-3 visa reflecting that employer, or after obtaining a new visa at a consulate. Your previous E-3 stamp does not transfer to a new sponsor.
