Get Access To All JobsSenior Linux Systems Engineer (Contract)
Location: Hybrid (San Diego, CA)
Duration: 6-Month Contract (Extension Possible)
About the Role
We’re hiring a Senior Linux Systems Engineer to support the development of a next-generation scientific instrument used in advanced protein analysis.
This is a high-impact contract role where you’ll own the reliability, deployment, and update infrastructure of a Linux-based system embedded inside a cutting-edge lab device. You’ll work closely with a small, highly technical engineering team preparing for a major product launch later this year.
* If you’ve built and deployed Linux systems in production environments—and can ensure they boot, update, and behave flawlessly in the field—this role is for you.
What You’ll Do
Design and implement robust Linux OS deployment and update mechanisms
Transition from package-based updates to atomic / A-B system updates
Ensure reliable system boot and recovery
Build and maintain Ubuntu 24.04-based system images
Improve system stability in real-world lab environments, especially USB device handling and peripherals
Enable seamless interaction with network storage systems (NFS / SMB)
Package and deploy system and application updates in a controlled, production-ready way
Proactively identify and fix system-level issues ahead of product launch
What You Bring
6–10+ years of experience in Linux systems engineering
Strong experience with Ubuntu (preferably 24.04)
Hands-on experience with OS-level deployments in production environments
Experience with system packaging and update mechanisms
Exposure to atomic updates, A/B partitioning, or rollback mechanisms
Ability to work independently with minimal supervision
Comfort working close to hardware or embedded systems
Experience with C# / .NET on Linux
Background in scientific instruments, embedded systems, or hardware-software integration
Experience supporting systems deployed across multiple locations
Work Environment
Hybrid role with approximately 3 days onsite (flexible for strong candidates)
Collaborative, small engineering team
* Hands-on work with physical lab equipment
Contract Details
6-month contract with strong likelihood of extension
Full-time (40 hours per week)
* Potential opportunity for temp-to-perm conversion for the right candidate

Search Software Systems Engineer Jobs in ConnecticutSoftware Systems Engineer Jobs in Connecticut: Frequently Asked Questions
Which companies in Connecticut sponsor visas for software systems engineers?
Defense and aerospace contractors are among the most active sponsors in Connecticut, including Raytheon Technologies, Pratt & Whitney, and Sikorsky. Financial services firms concentrated in Stamford, such as UBS and Synchrony, also sponsor systems engineering talent. Hartford-area insurers like Cigna and Aetna have engineering divisions that file H-1B petitions for software systems roles on a recurring basis.
Which visa types are most common for software systems engineer roles in Connecticut?
The H-1B is by far the most common visa category for software systems engineers in Connecticut, as the role typically qualifies as a specialty occupation requiring at least a bachelor's degree in computer science, software engineering, or a related field. Candidates from Canada or Mexico may pursue TN visa status under the USMCA. Those with extraordinary ability in their field sometimes qualify for O-1A consideration.
Which cities in Connecticut have the most software systems engineer sponsorship jobs?
Stamford leads for private-sector sponsorship given its concentration of financial technology and corporate headquarters. Hartford is a strong second, driven by insurance technology and defense contracting employers. East Hartford hosts United Technologies and Pratt & Whitney engineering operations, making it a notable hub. New Haven attracts biotech and research-adjacent systems engineering roles, partly supported by Yale University's affiliated industry partners.
How to find software systems engineer visa sponsorship jobs in Connecticut?
Migrate Mate filters job listings specifically by visa sponsorship availability, so you can search for software systems engineer roles in Connecticut without sorting through positions that don't offer sponsorship. The platform surfaces employers in Connecticut's defense, fintech, and insurance tech sectors that have an active history of sponsoring work visas, which is especially useful given how unevenly sponsorship is distributed across the state's employers.
Are there any Connecticut-specific factors that affect visa sponsorship for software systems engineers?
Connecticut's software systems engineering roles at defense contractors often require security clearances, which can complicate or preclude sponsorship for foreign nationals who are not yet permanent residents. The Department of Labor's prevailing wage determinations for Fairfield County, which includes Stamford, are set at a high level relative to the rest of the state, which influences whether smaller employers are willing to take on sponsorship costs. New Haven's proximity to Yale creates a pipeline of international talent that local biotech employers actively tap.
What is the prevailing wage for sponsored software systems engineer jobs in Connecticut?
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.
