- Build and maintain CI/CD pipelines using CircleCI
- Monitor system performance and implement comprehensive logging/alerting with CloudWatch and security monitoring tools
- Integrate with EV charging hardware protocols (OCPP, ISO 15118) and third-party charging networks
- Optimize database performance and implement efficient caching strategies for real-time charging data
Frontend Development
- Build responsive, intuitive web applications using modern JavaScript frameworks (React, Vue.js, or Angular)
- Create real-time charging station status dashboards and energy consumption analytics
- Implement EV charging session management and billing interfaces
- Ensure cross-browser compatibility and optimal performance
- Develop secure user authentication and session management for charging network access
- Create reusable UI components and maintain design system consistency
Mobile Application Development
- Develop native iOS applications using React Native
- Implement EV charging station finder, session initiation, and payment processing features
- Create offline functionality and data synchronization for charging session data
- Integrate mobile apps with charging station hardware and backend APIs
- Implement location services and mapping for charging station discovery
- Ensure mobile security best practices and app store compliance
- Optimize mobile performance for EV drivers
Data Management & EV Integration
- Design and implement data ingestion pipelines for charging station telemetry and usage data
- Develop ETL processes for energy consumption analytics and billing data
- Create APIs for seamless integration with EV charging hardware and third-party networks
- Implement data governance and privacy compliance measures (PIPEDA, GDPR)
- Build analytics and reporting capabilities for charging network operators and fleet managers
- Work with time-series data for energy usage, demand forecasting, and grid integration
Required Qualifications
Technical Skills
- 5+ years of full stack development experience
- 3+ years of hands-on AWS experience with core services (EC2, S3, RDS, Lambda, API Gateway)
- Strong proficiency in .NET (Core/Framework) and Go for backend development
- Server-side security hardening experience including network security, access controls, and vulnerability management
- Experience with modern frontend frameworks (React, Vue.js, Angular)
- Experience developing cross-platform mobile apps using React Native
- (Nice to have) Mobile development experience with iOS (Swift) and Android (Kotlin/Java)
- Database expertise (PostgreSQL, MySQL, DynamoDB, or similar)
- RESTful API design and GraphQL knowledge
- Version control with Git and collaborative development workflows
About Soneil Spark
At Soneil Spark, we are pioneering next-generation electric-vehicle charging solutions and advanced energy storage systems for both retail and commercial markets, pushing the boundaries of efficiency, intelligence, and adaptability in every product we make.
Our team of hardware, firmware, and software experts develop high-quality, cutting-edge power systems, AI-powered energy management, and scalable charging infrastructure to create smarter, more adaptable power solutions for a rapidly evolving world.
Engineering the Future of Smart Energy
By incorporating advanced technologies such as vehicle-to-grid (V2G) integration, bidirectional charging, and adaptive power distribution, we’re creating more intelligent and responsive energy systems.
Our focus is on solving critical challenges such as limited power availability, high infrastructure costs, and grid constraints—barriers that must be overcome for EV adoption to scale. By leveraging AI and innovative power and mobile charging systems, we are developing solutions that make charging and energy management more accessible, efficient, and cost-effective.
Join the Visionaries We value bold ideas with real impact, and need builders, problem-solvers, and pioneers in hardware, firmware, software, mechanical, and electrical engineering, embedded systems, and field technicians to bring first-of-its-kind EV charging and energy storage technology to life.
If you want to invent, not just improve, Soneil Spark is where you belong.
