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 Senior Python Engineer
Align your credentials before you apply
Your Australian three-year bachelor's degree in computer science, software engineering, or a related field satisfies the E-3 specialty occupation requirement. Gather certified transcripts and a credential equivalency statement before your first interview to avoid delays.
Target employers with active LCA history
Search DOL's FLAG portal for employers who have filed Labor Condition Applications for software engineering roles. Employers already familiar with the LCA certification process move faster and are less likely to stall on E-3 sponsorship questions.
Confirm your role meets specialty occupation criteria
USCIS requires that a Senior Python Engineer position normally demands a specific bachelor's degree, not just any degree. If the job description says 'degree preferred,' ask the employer to revise it to 'required' before the LCA is filed.
File your LCA before booking your consulate appointment
DOL must certify your LCA before you can apply for your E-3 visa at a U.S. consulate in Australia. Use Migrate Mate's E-3 filing service to handle your LCA and visa paperwork so nothing is submitted out of sequence.
Prepare for nonimmigrant intent questions at your interview
E-3 visas are nonimmigrant, so consular officers will ask about your ties to Australia and your plans after the visa period. Having a clear, honest answer about your current role, family, and assets back home keeps the interview straightforward.
Senior Python Engineer jobs are hiring across the US. Find yours.
Find Senior Python Engineer JobsSenior Python Engineer E-3 Visa: Frequently Asked Questions
How do I find Senior Python Engineer jobs that offer E-3 visa sponsorship?
Search Migrate Mate to filter Senior Python Engineer roles by E-3 visa sponsorship. Most general job boards don't flag E-3 willingness, so you'd otherwise need to manually research each employer's immigration history. Migrate Mate surfaces roles where employers are already open to sponsoring Australian engineers on the E-3.
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 Senior Python Engineer role qualify as a specialty occupation for the E-3?
Yes, provided the position genuinely requires a bachelor's degree or higher in a specific field like computer science or software engineering. The key is how the role is described: it must require a relevant degree, not merely prefer one. If a job posting says 'degree preferred,' the employer should update the language before filing the LCA with DOL.
How does the E-3 visa compare to the H-1B for a Senior Python Engineer?
The E-3 has no lottery and no annual cap, so you can apply any time of year once you have a job offer. H-1B registration opens once a year in March, and most software engineers don't get selected. For an Australian Python engineer, the E-3 is a direct path that avoids the uncertainty and multi-year wait that H-1B applicants routinely face.
Can I switch to a different Python engineering role after I get my E-3 visa?
Yes, but you need a new LCA and visa application for each employer change. Your current E-3 is tied to the sponsoring employer and the specific position listed on the LCA. If you move to a new company, that employer must file a new LCA with DOL and you'll need to apply for a new E-3 at a U.S. consulate before starting work.
