- Install, configure, and maintain databases (e.g., MongoDB, SQL) for data persistence and telemetry.
- Implement and validate cybersecurity compliance across all system components.
- Lead the creation of automated testing and integration frameworks to ensure reliability and performance at scale.
- Mentor and guide junior engineers, fostering technical excellence and collaboration.
Qualifications & Experience
Essential:
- 7+ years of professional software engineering experience, with at least 5+ years of hands-on development in C, C++, Python, and/or Perl.
- Strong background in Linux system integration and administration (RHEL preferred).
- Proven experience with real-world system integration, delivery, and deployment.
- Hands-on experience in test automation, CI/CD pipelines, and validation frameworks.
Preferred:
- Familiarity with industrial communication protocols (Modbus, DNP3, IEC 61850).
- Experience with distributed control systems, embedded Linux, or power systems.
- Working knowledge of cybersecurity principles in critical infrastructure systems.
- Demonstrated ability to lead technical projects and mentor junior engineers.
- Strong analytical, problem-solving, and communication skills.
What We Offer
- Opportunity to shape the future of microgrid control technology in a rapidly evolving energy landscape.
- Collaborative, innovation-driven environment with global project exposure.
- Competitive compensation and a comprehensive benefits package.
Salary Range: 113,500.00 - 170,500.00 USD Annual
This pay range represents the minimum and maximum compensation that the position offers, and final compensation can vary within the range depending on work location, job experience, skills, and relevant educational attainment and/or training.

Get Access To All JobsTips for Finding TN Visa Sponsorship as a Senior Fullstack Software Engineer
Verify your degree aligns with Systems Analyst
TN visa classification for fullstack engineers falls under Systems Analyst. Your degree must be in computer science, software engineering, or a closely related field. A general IT or business degree without a technical focus can trigger a TN denial at the port of entry.
Build a support letter that maps code to systems analysis
CBP officers approve or deny TN petitions on the spot. Your employer's support letter must explicitly frame your fullstack role as systems analysis, describing how you design, develop, and integrate software systems, not just write code for features.
Target employers with cross-border hiring experience
Search for companies that have previously sponsored Canadian or Mexican professionals under USMCA. Employers familiar with TN sponsorship already have HR workflows and legal counsel in place, which shortens your offer-to-start timeline significantly.
Use Migrate Mate to find TN-ready engineering roles
Sifting through job listings for employers open to TN sponsorship wastes time. Migrate Mate filters Senior Fullstack Software Engineer roles by TN visa sponsorship readiness, so you're applying to companies already prepared to support your classification.
Negotiate TN renewal timing into your offer terms
TN status is granted in three-year increments with unlimited renewals. Before signing your offer, confirm your employer will initiate renewal paperwork at least 60 days before your status expires to avoid any gap in your work authorization.
Prepare for secondary inspection if your role is ambiguous
Fullstack roles that include product management, team leadership, or business analysis duties can raise questions at a Canadian port of entry. Carry documentation showing that software systems design and development are your primary responsibilities, not a secondary function.
Senior Fullstack Software Engineer TN Visa: Frequently Asked Questions
Does a Senior Fullstack Software Engineer role qualify for TN visa status?
Yes, fullstack engineering roles qualify under the TN Systems Analyst category, which covers professionals who design, develop, and integrate software systems. The role must require a bachelor's degree in a relevant technical field. Positions that blend significant non-technical duties, such as product ownership or project management, may face closer scrutiny and should be framed carefully in the employer's support letter.
How does TN visa sponsorship compare to H-1B for fullstack engineers?
TN is significantly faster and more predictable for Senior Fullstack Software Engineers. There is no annual lottery, no cap for Canadian citizens, and no multi-month USCIS adjudication wait. A Canadian engineer can receive TN status at a port of entry the same day an offer is accepted. H-1B visa requires entering a lottery with roughly a 25% selection rate and a filing window limited to one period per year.
Can Mexican citizens get TN sponsorship for Senior Fullstack Software Engineer roles?
Yes, Mexican citizens can obtain TN status for qualifying fullstack engineering roles under USMCA. Unlike Canadians, Mexican nationals must apply at a U.S. consulate in Mexico and receive a TN visa stamp before entering the country. The Systems Analyst category applies equally, and the same degree and job-duty requirements must be met.
How do I find employers willing to sponsor TN visas for this role?
Most job listings don't explicitly advertise TN sponsorship readiness, which makes filtering difficult on general job boards. Migrate Mate is built specifically for this search, letting you identify Senior Fullstack Software Engineer roles from employers already familiar with TN visa sponsorship under USMCA, so you're not spending time on companies unprepared to support your status.
What documents does my employer need to provide for my TN application?
Your employer must provide a support letter on company letterhead that states your job title, a description of your duties framed around systems analysis and software development, your educational qualifications, the anticipated duration of employment, and confirmation that the role requires a professional in the Systems Analyst USMCA category. Canadian citizens present this letter directly at the port of entry along with their passport and credential evidence.
