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
Compensation: $85,000 - $135,000 + annual bonus (range varies depending on location; paid in local currency)
Reports To: Technical Solutions Manager
Location: Remote – Canada or USA
About the Role:
The Technical Solutions Engineer will play a key role in supporting the development, evaluation, and integration of utility-scale energy storage systems (ESS) with a focus on battery technology and performance in integrated systems. This role supports both internal product development and external solution customization, ensuring seamless operation and coordination between the Battery Product, Inverters, EMS and grid interface.
This position requires deep fluency in battery cell and pack-level degradation mechanisms, the ability to translate degradation curve behavior into commercial and contractual strategy (warranties, guarantees, storage/charging requirements), and the judgment to drive design and process improvements back into the product roadmap. The ideal candidate is equally comfortable building degradation models in Excel/Python, defending assumptions in front of an Independent Engineer, and sitting across the table from R&D to push for a design change.
This role supports both internal product development and external solution customization. For internally developed solutions, the engineer will work closely with R&D, global engineering to provide direct input on design features, validation strategies, and system sizing requirements. For externally procured products, the focus will be on leading technical due diligence, ensuring standards compliance, and transferring product knowledge to internal engineering, applications, and execution teams.

Battery Performance & Degradation Strategy
- Own and evolve degradation modeling methodology and strategy in externally facing degradation curves for product and system warranties.
- Maintain and improve internal degradation and throughput tools (capacity models, throughput analysis, duty cycle tools etc.) ensuring accuracy across models, chemistries, and climate conditions.
- Serve as the primary technical liaison between project and performance engineering and R&D, feeding field/factory degradation insights and failure trends back into cell selection, thermal management, and DC Block design decisions.
- Monitor and interpret emerging battery chemistries and design (e.g., winding/stacking, blade cells, sodium-ion) for their degradation, safety, and warranty implications, and assess their fit against existing performance guarantee structures.
Cross-functional Support and Customization
- Coordinate cross-functional communication to introduce new products to internal stakeholders, including engineering, project execution, and commercial teams.
- Lead internal discussions with engineering, product, and software/controls teams to troubleshoot control strategies and support platform optimization.
- Provide technical input and coordination for project-specific requirements, custom feature requests, or client-specific configurations.
- Contribute to the development of internal documentation, reference templates, and knowledge-sharing tools that support consistent product execution across regions.
- Collaborate closely with global R&D and applications engineering teams, to align on feature roadmaps and deployment readiness.
- Perform other related duties as assigned by management.
Required Qualifications and Skills:
- Bachelor’s degree in electrical engineering, materials science, electrochemistry, or a related discipline; preference given to candidates with a postgraduate degree in engineering.
- Minimum 5 years of experience in engineering, R&D, or product management within battery storage, battery cell development, or related industries.
- Direct experience in battery product development, cell testing, or energy storage applications is strongly preferred.
- Strong knowledge of LFP battery cells, DC Blocks, and Energy Storage Systems.
- Familiarity with key standards and certifications related to batteries and ESS products, including UL 9540, UL9540A, UL 1973, UN 38.3, IEC 62933, IEC 62619, and other applicable codes or testing standards.
- Experience collaborating with international partners, particularly engineering or manufacturing teams across global time zones.
- Demonstrated ability to lead or contribute to the development of internal engineering tools, system models, or automation processes.
- Strong technical, analytical, and troubleshooting skills, with a hands-on approach to product validation and integration.
- Proficiency in Mandarin is a plus but not required.
Key Competencies
- Ability to collaborate effectively across diverse, cross-functional teams and international time zones.
- Strong technical communication skills, with the ability to navigate discussions across internal teams and represent engineering topics in customer or Independent Engineer (IE) reviews — particularly in coordination with R&D counterparts across Asia, North America, and Europe.
- Experience with product onboarding, technical documentation review, and vendor qualification processes is highly desirable.
- Excellent organizational skills, and clear written and verbal communication across global teams.
- Flexibility to travel, including international travel as required (up to 15%) for vendor assessments, integration testing, and industry events.

Hyperscalers like Google and Meta also hire for this function. Mid-size SaaS companies in the Bay Area and Los Angeles frequently sponsor as well, particularly those with international sales or customer success operations.
What visa types are most commonly used for technical solutions engineer roles in California?
The H-1B is the most common visa for technical solutions engineers in California. The role typically qualifies as a specialty occupation because it requires a bachelor's degree or higher in computer science, engineering, or a related technical field. Australian citizens may qualify for the E-3 visa as an alternative. Candidates already holding L-1 visa status through intracompany transfers also fill this role at multinational employers with California offices.
Which cities in California have the most technical solutions engineer sponsorship jobs?
San Francisco and the broader Bay Area account for the largest share of technical solutions engineer sponsorship jobs in California, driven by the concentration of enterprise software and cloud infrastructure companies. San Jose and Santa Clara are particularly active given Cisco and other networking firms headquartered there. Los Angeles has a growing presence, especially among media tech and e-commerce platforms. San Diego and Sacramento represent smaller but active markets.
How to find technical solutions engineer visa sponsorship jobs in California?
Migrate Mate filters job listings specifically by visa sponsorship availability, making it straightforward to find technical solutions engineer roles in California where employers are actively sponsoring. Rather than sorting through general job boards where sponsorship status is unclear, Migrate Mate surfaces only roles from employers with a demonstrated history of sponsoring international candidates, which is especially useful in California's competitive market.
Are there state-specific considerations for technical solutions engineers pursuing sponsorship in California?
California's prevailing wage determinations for technical solutions engineers tend to reflect the high cost of living in the Bay Area and Los Angeles, which affects the wage levels employers must certify on Labor Condition Applications. The state's large university system, particularly UC Berkeley, Stanford, and UCLA, creates a strong pipeline of international candidates who often pursue sponsorship after OPT. California also has no state-level restrictions on employer-employee relationships that affect standard H-1B filings.
What is the prevailing wage for sponsored technical solutions engineer jobs in California?
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.
