- Proficiency with automated testing using PyTest, including fixtures, mocking, and parameterization
- Understanding of clean code principles, error handling, type hints, and maintainable design
API Engineering:
- Hands-on experience building RESTful APIs using Flask, Django, or FastAPI
- Knowledge of authentication and authorization mechanisms (JWT, OAuth2)
- Experience implementing API versioning, request validation, and structured error handling
- Understanding of performance considerations such as throughput, latency, and caching
AWS Cloud Services:
- Practical experience with key AWS services including: Lambda, S3, Step Functions, Glue, EC2, ECS/Fargate, RDS, Redshift, CloudWatch

- Generate and refine unit tests and integration test scaffolding
- Improve readability, documentation, and boilerplate reduction
- Assist with refactoring, code reviews, and exploratory coding

Job Roles at Unisys Companies
How to Get Visa Sponsorship in Unisys Visa Sponsorship USA
Target Unisys's core technical divisions
Unisys hires most sponsored talent in software development, cloud infrastructure, and IT consulting. Aligning your application to these divisions, rather than corporate or administrative functions, puts you closest to where sponsorship activity concentrates.
Lead with specialty occupation qualifications
H-1B approval at Unisys depends on your role qualifying as a specialty occupation. Emphasize your degree field's direct relevance to the job description. A degree in computer science or engineering strengthens your case significantly.
Apply when positions are actively open, not speculatively
Unisys sponsorship is tied to specific funded headcount. Targeting live job postings rather than sending cold applications improves your odds. Migrate Mate surfaces verified sponsors so you can filter by real sponsorship history and find current Unisys openings.
Use TN visa eligibility as a differentiator if you're Canadian or Mexican
Unisys sponsors TN visas, which have no cap or lottery. If you're a Canadian or Mexican national in a qualifying TN occupation like engineer or computer systems analyst, flag this in your application, it removes a significant hiring barrier for the employer.
Prepare for a structured, enterprise-style hiring process
As a large IT services company, Unisys typically runs multi-stage interviews involving technical assessments and behavioural rounds. Prepare for both. Demonstrating project delivery experience and enterprise technology familiarity aligns well with what Unisys hiring managers evaluate.

Get Access To All JobsFrequently Asked Questions
Does Unisys sponsor H-1B visas?
Yes, Unisys sponsors H-1B visas and has a consistent track record of doing so for roles in software engineering, IT consulting, and infrastructure. The company files petitions tied to specific open positions, so sponsorship is available when a qualifying role is budgeted and your background aligns with the specialty occupation requirement.
Which roles at Unisys are most likely to receive visa sponsorship?
Sponsorship at Unisys is concentrated in technical roles, particularly software engineers, cloud architects, systems analysts, and IT consultants. These positions align with the specialty occupation standard required for H-1B classification. Corporate, sales, and generalist roles are less commonly sponsored. Focusing your search on Unisys's technology delivery and solutions divisions gives you the strongest chance.
Does Unisys support Green Card sponsorship?
Yes, Unisys sponsors employment-based Green Cards through the EB-2 and EB-3 categories. These pathways typically become available after an employee has been with the company for a period of time and demonstrated strong performance. If long-term U.S. residency is your goal, it's worth raising this during the offer negotiation stage rather than waiting until you're already employed.
How do I find open visa-sponsored jobs at Unisys?
The most reliable approach is to search for Unisys directly on Migrate Mate, which aggregates jobs from verified sponsors and lets you filter by visa type and company. This ensures the roles you're targeting are from employers with a documented sponsorship history, rather than relying on job listings that don't disclose immigration support upfront.
How do I approach the Unisys application process as a visa sponsorship candidate?
Be transparent about your visa status early, ideally in your cover letter or at the first recruiter screen. Unisys has experience with sponsored hires, so this rarely disqualifies candidates in technical roles. Prepare for a structured hiring process with technical and behavioural rounds. Having your documentation in order and understanding whether your role qualifies as a specialty occupation will help the process move efficiently once an offer is extended.
