JOB SUMMARY
We are looking for a Senior Software Engineer to lead the technical direction of our AI Agent initiatives. This is a backend engineering role first, focused on building scalable, reliable systems that happen to use modern AI techniques. You will architect and operate production-grade backend services and agentic workflows that solve complex, non-deterministic problems. While LLMs are a core capability, success in this role comes from strong systems thinking, designing for correctness, observability, failure recovery, and long-term maintainability. You will serve as a technical anchor for the team—mentoring junior engineers, setting engineering standards, and working with leadership to turn AI concepts into dependable, customer-facing systems. Level machine learning expertise and innovation capacity are essential.
JOB DESCRIPTION
What You Will Do
Architectural Leadership
- Design and own scalable backend architectures and complex agent-driven workflows. This includes service boundaries, data flows, failure handling, observability, and performance characteristics—not just model interaction.
Agent Behavior Engineering (Not Just Prompting)
- Design and productionize agent behaviors including tool invocation, state management, memory strategies, and reasoning control. Prompts are treated as code: versioned, tested, reviewed, and evolved alongside backend logic for reliability, cost, and latency.
Systemic Quality & Code Health
- Set the bar for clean, readable, maintainable code across the Python backend. Establish patterns and standards that allow AI-heavy systems to remain understandable and operable over time.
Testing & Evaluation of Probabilistic Systems
- Design testing strategies for non-deterministic AI components, including behavioral regression testing, automated evaluations, and guardrails that reduce blast radius in production.
Technical Mentorship
- Lead code reviews as a teaching tool, run architectural discussions, and actively mentor Engineer 1–2 developers in backend fundamentals, system design, and operational thinking.
Operational Excellence & Production Ownership
- Own CI/CD, deployment, and runtime health. Lead production support efforts and help build a strong on-call culture where systems are observable, diagnosable, and resilient under real-world load.
Customer-Facing Engineering
- Partner with product and design to deliver high-traffic, customer-facing experiences where AI responses must meet clear standards for latency, reliability, and UX—not just correctness.
Cross-Functional Technical Leadership
- Translate product goals into pragmatic technical roadmaps, identifying scaling risks, technical debt, and AI-specific failure modes early.
Advanced Debugging & Incident Leadership
- Lead investigations into complex issues spanning multiple services, data pipelines, or emergent agent behaviors in production.
WHAT WE’RE LOOKING FOR
Senior Backend Engineering Depth
- Extensive experience designing, building, and operating backend systems in Python, including asynchronous frameworks (FastAPI, asyncio) and distributed service architectures.
Production Experience at Scale
- A track record of owning customer-facing systems in production. You understand uptime, latency budgets, incident response, and the cost of unreliable behavior.
AI Systems Intuition
- Hands-on experience integrating LLMs into real systems, with a clear understanding of their limitations, failure modes, and operational risks. You think in terms of workflows, control flow, and safeguards—not just prompt quality.
Agent & Tooling Experience
- Experience building AI agents that interact with tools, APIs, and external systems, including managing agent state, bounding autonomy, and preventing pathological behaviors (loops, hallucinations, cascading failures).
Support & Reliability Mindset
- Comfortable being responsible for systems after launch. You design software that is “easy to wake up to” when something goes wrong.
Strong System Design Skills
- Experience with microservices, data stores, queues, and high-throughput APIs—and the judgment to keep designs as simple as possible.
Mentorship & Engineering Culture
- A desire to raise the bar for those around you through feedback, example, and thoughtful technical leadership.
Pragmatism
- You enjoy leveraging advanced AI capabilities, but you prioritize stability, debuggability, and long-term maintainability over novelty.

Get Access To All JobsTips for Finding Visa Sponsorship as a Python Engineer
Target companies with H-1B filing history
Companies that have sponsored Python Engineers before are far more likely to do it again. Look for employers with consistent H-1B disclosure data in software engineering roles rather than cold-applying to firms with no sponsorship track record.
Frame your degree field carefully
H-1B specialty occupation requires a degree directly related to the role. Computer science, software engineering, and mathematics are clean fits. If your degree is in a different field, be prepared to explain the connection through coursework or a credential evaluation.
Highlight production-scale Python experience
Sponsors want engineers who have shipped real systems, not just scripted automation. Emphasize experience with frameworks like Django, FastAPI, or Flask, and production deployments on AWS, GCP, or Azure. This distinction matters during H-1B specialty occupation assessment.
Know your visa timeline before accepting offers
If you need an H-1B cap-subject petition, the October 1 start date is fixed. You cannot begin work before it activates. Cap-exempt employers like universities and nonprofits can file and start employment year-round, which is worth factoring into your job search.
Ask about premium processing upfront
Standard H-1B adjudication can take three to six months. Premium processing reduces this to roughly two to three weeks. Confirming whether your employer will use premium processing helps you plan your start date and avoid gaps in work authorization.
Use Migrate Mate to filter for verified sponsors
Not every job listing that mentions visa sponsorship will actually follow through. Migrate Mate surfaces Python Engineer roles from employers with documented sponsorship history, so you spend time applying to companies that have committed to the process before.

Find Python Engineer JobsFrequently Asked Questions
Does a Python Engineer role qualify for H-1B sponsorship?
Yes. Python Engineer roles qualify as H-1B specialty occupations because the position normally requires at least a bachelor's degree in computer science, software engineering, or a closely related field. USCIS scrutinizes job descriptions closely, so employers typically document the technical complexity of the role, including system design responsibilities and language-specific requirements, to support the petition.
What degree do I need for a Python Engineer to get H-1B sponsorship?
A bachelor's degree in computer science, software engineering, information technology, or mathematics is the cleanest fit. Degrees in other STEM fields can work if you can demonstrate their direct relevance to the Python Engineer role through coursework or a credential evaluation. A three-year Australian bachelor's degree is generally accepted as equivalent to a U.S. four-year degree for H-1B purposes.
How competitive is H-1B sponsorship for Python Engineers compared to other tech roles?
Python Engineers appear frequently in H-1B disclosure data because demand for the skill set is high across industries including fintech, healthcare technology, and cloud infrastructure. The H-1B lottery applies equally regardless of role, with a roughly 25% selection rate in recent years. However, Python Engineers working for cap-exempt employers such as universities or research institutions are not subject to the lottery.
Can I get sponsored as a Python Engineer without a traditional CS degree?
It is possible but harder. USCIS allows work experience to substitute for formal education in some cases, using a three-for-one rule where three years of relevant experience replaces one year of a bachelor's degree. However, this path invites more scrutiny and is employer-dependent. Some employers will not file H-1B petitions without a formal four-year degree, so it is worth confirming their requirements early.
Where can I find Python Engineer jobs that offer visa sponsorship?
Migrate Mate lists Python Engineer roles specifically from employers with verified sponsorship history. Searching general job boards often surfaces listings that mention sponsorship without the employer having ever filed a petition. Migrate Mate filters for companies that have documented H-1B or other work visa filings, which significantly improves your chances of reaching an offer that actually leads to a sponsored petition.
What is the prevailing wage requirement for sponsored 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.
