Who We Are
Welcome to e-STORE, a proud member of the Canadian Solar Inc. (NASDAQ: CSIQ) family! We’re leading the way in designing, building, and integrating advanced battery energy storage systems for utility-scale projects. Our mission? To accelerate the world’s renewable energy transition and create a more sustainable, resilient energy future for everyone.
With our innovative SolBank lithium-iron phosphate battery technology and comprehensive project services, we’re not just building products we’re powering communities and making a difference worldwide.
Position Title: Technical Solutions Engineer
Department: Technical Solutions

Get Access To All JobsTips for Finding Visa Sponsorship as a Technical Solutions Engineer
Align your degree to the role
Technical Solutions Engineer job descriptions often list computer science, engineering, or information systems as required fields. Pull the O*NET profile for this occupation and match your transcript's declared major to the specialty occupation definition USCIS uses when reviewing petitions.
Target companies with LCA filing history
Use Migrate Mate to find employers who have already filed Labor Condition Applications for Technical Solutions Engineer or closely related titles. Prior LCA activity signals an established sponsorship process, not a first-time experiment where your petition becomes the trial run.
Verify prevailing wage tier before negotiating
Run your target city and job title through the OFLC Wage Search before salary discussions begin. LCA approval requires the offered wage to meet the prevailing wage level, and negotiating below Level II for a role requiring client-facing technical depth can trigger a DOL audit.
Distinguish hybrid roles clearly in your documents
Technical Solutions Engineers blend pre-sales engineering with post-sales implementation. If your resume blends both, employers filing an H-1B petition may struggle to frame a coherent specialty occupation argument. Separate the technical duties from the account-management duties explicitly in your job description documentation.
Confirm STEM OPT eligibility with your DSO early
If your degree is in computer science, information technology, or a related STEM-designated field, you may qualify for a 24-month STEM OPT extension. Your employer must be enrolled in E-Verify, and your DSO must authorize the extension before your initial OPT EAD expires.
File the LCA before your offer letter deadline
Employers can't submit your H-1B petition until DOL certifies the LCA, which USCIS then receives as a required exhibit. Build at least three weeks of LCA processing time into your start-date negotiation so a tight offer deadline doesn't force a withdrawn petition.
Frequently Asked Questions
Does a Technical Solutions Engineer role qualify as a specialty occupation for H-1B purposes?
Yes, in most cases. USCIS evaluates whether the position normally requires at least a bachelor's degree in a directly related field such as computer science, engineering, or information systems. Because Technical Solutions Engineers routinely apply deep technical knowledge in networking, cloud infrastructure, or software integration, the role generally satisfies the specialty occupation standard. Employers strengthen the petition by writing a job description that emphasizes the technical duties over the client-relationship component.
Which visa types are available to foreign nationals applying for Technical Solutions Engineer jobs?
H-1B is the most common path for employer-sponsored candidates, covering the specialty occupation requirement that this role typically meets. F-1 graduates may work under OPT or STEM OPT while an H-1B petition is pending. Australian nationals can pursue the E-3 visa, which requires an LCA but has no lottery. Canadian and Mexican nationals in qualifying engineering or computer science roles may be eligible for TN visa status.
How do I find Technical Solutions Engineer jobs where employers are willing to sponsor visas?
Migrate Mate lists Technical Solutions Engineer roles from employers with verified sponsorship history, so you can focus your applications on companies that have already committed to filing for international candidates rather than those exploring it for the first time.
Does the client-facing nature of this role create any extra H-1B hurdles?
It can. If the role involves working at multiple client sites, the employer may need to file amended petitions or additional LCAs for each work location, depending on how USCIS interprets the placement arrangement. Employers who already have established multi-site LCA processes handle this routinely. During your offer negotiation, ask the recruiter whether the company has sponsored candidates in field-based or client-site roles before.
What degree fields best support a Technical Solutions Engineer sponsorship petition?
Computer science, computer engineering, electrical engineering, and information systems degrees map most directly to this occupation's technical requirements. Applied mathematics and software engineering degrees are also accepted when the job description demonstrates a clear connection. A business or general management degree alone is unlikely to satisfy the specialty occupation standard unless paired with a technical minor or directly relevant coursework that the employer documents in the LCA.
What is the prevailing wage requirement for sponsored Technical Solutions 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.
