Implements and optimizes components within existing distributed systems under guidance. Applies basic scalability requirements, conducts performance/load testing, and configures resiliency features (retries, circuit breakers, timeouts) to handle network variability. Builds telemetry, alerts, and runbook-driven procedures; delivers scoped features and fault-injection tests; and helps implement basic data replication and synchronization. Assists with on-call rotations, uses automation/IaC scripts to troubleshoot, and follows change, security, and compliance procedures (encryption, access controls, remediation plans) while escalating complex issues to senior engineers.
ROLE AND RESPONSIBILITIES
As a Core Infrastructure Software Engineer, you will:
- Design, develop, and operate highly available, scalable, and fault-tolerant microservices across control plane, connectivity, distributed-systems data plane, and Linux daemon technologies.
- Contribute throughout the product lifecycle, from conceptualization and product definition through design, development, launch, and operational maturity.
- Identify opportunities to automate engineering workflows across development, testing, troubleshooting, operations, and documentation, leveraging AI-assisted and agentic approaches where appropriate.
- Measure and improve reliability, delivery velocity, operational efficiency, customer outcomes, and engineering productivity, while sharing effective practices across the team.
- You should be a hands-on, adaptable, and self-motivated engineer who learns quickly, applies new tools thoughtfully, and enjoys solving challenging high-availability and scalability problems.
BASIC QUALIFICATIONS

Get Access To All JobsTips for Finding OPT Sponsorship as an Infrastructure Engineer
Target companies with active H-1B filing histories
Employers who have sponsored H-1B visas for infrastructure roles in the past are far more likely to do it again. Check USCIS H-1B visa disclosure data to verify a company sponsors roles like yours before investing time in their application process.
Lead with your STEM OPT timeline upfront
Infrastructure Engineer roles fall squarely under STEM-designated CIP codes, making you eligible for a 24-month STEM OPT extension. Mentioning your full three-year authorization window early removes the biggest hesitation most hiring managers have about OPT candidates.
Emphasize cloud certifications on your resume
AWS, Azure, and GCP certifications signal job-ready skills that reduce employer onboarding costs. Certified candidates consistently move faster through infrastructure hiring pipelines, which matters when your OPT start date creates a narrow window for completing the process.
Apply to mid-size tech companies, not just large enterprises
Companies with 200 to 2,000 employees often have dedicated infrastructure teams but less competition than FAANG. They also tend to make faster hiring decisions, which reduces the risk of an offer arriving too late relative to your OPT authorization start date.
Frame your OPT period as immediate availability
Many infrastructure teams struggle to fill roles quickly. Positioning your OPT status as meaning you can start now, without waiting for a visa transfer or petition cycle, reframes the conversation from a compliance concern into a staffing advantage for the employer.
Build a portfolio of infrastructure projects with measurable outcomes
Concrete results, such as reduced deployment times, improved uptime percentages, or cost savings from cloud optimization, give hiring managers something defensible when advocating internally to HR about sponsoring an OPT candidate for a permanent role.
Infrastructure Engineer OPT: Frequently Asked Questions
Do Infrastructure Engineer roles qualify for the STEM OPT extension?
Yes. Infrastructure Engineering roles typically fall under STEM-designated degree programs including computer science, information technology, computer engineering, and electrical engineering. If your degree qualifies, you can apply for a 24-month STEM OPT extension after your initial 12-month OPT period, giving you up to three years of total work authorization without employer sponsorship of an H-1B.
How common is H-1B sponsorship for Infrastructure Engineer positions?
Infrastructure Engineer is one of the more consistently sponsored roles in tech. Employers regularly file H-1B petitions for these positions because demand for qualified candidates routinely outpaces domestic supply, particularly in cloud infrastructure, DevOps, and network engineering. Companies with existing infrastructure teams and a history of H-1B filings are your strongest targets. You can browse OPT-friendly infrastructure roles directly on Migrate Mate.
Can I work as an Infrastructure Engineer on OPT if my degree is in electrical engineering rather than computer science?
Yes, provided the role has a direct connection to your field of study. Infrastructure Engineering spans both software and hardware systems, and electrical engineering degrees are accepted for roles involving network architecture, data center operations, and embedded systems. Your DSO will need to confirm the position relates to your degree program when authorizing your OPT, so review the job description carefully before applying.
What should I do if an Infrastructure Engineer role requires a security clearance?
Most security clearances require U.S. citizenship or permanent residency, which OPT students do not hold. Roles requiring a clearance are effectively off-limits during OPT. Filter these out early by reading job descriptions carefully for language like "requires active clearance," "must be a U.S. citizen," or "clearance required." Focus instead on private-sector infrastructure roles, which represent the majority of open positions and have no clearance requirements.
Does the 90-day unemployment limit apply between infrastructure jobs on OPT?
Yes. F-1 students on OPT cannot accumulate more than 90 days of unemployment during the standard OPT period, and that limit increases to 150 days if you receive a STEM OPT extension. Infrastructure roles can sometimes have longer hiring cycles due to technical interviews and background checks, so starting your job search early and keeping your pipeline active is important for staying within the limit.
