About The Position

We are looking for a Full Stack Software Developer to join our small, high-impact engineering team — someone who wants to own a new product end-to-end and see their code matter in the physical world. Your primary focus will be a new consumer-facing platform that enhances the driver experience at IONNA chargers, building across the full stack from React front-ends to Node.js backend services and data pipelines. You will also contribute to our internal operations platform — used across the organization to analyze charging performance, surface alerts, debug hardware and software issues, and resolve problems impacting real drivers at real chargers. This isn't a maintenance role. You will build a new product on a modern stack (React, TypeScript, Next.js, Node.js), ship day-to-day features across the platform, develop data pipelines that drive operational decisions, and improve the tooling your teammates rely on. The team is small enough that your architectural opinions matter and your code ships fast — we value ownership, speed, and quality over process overhead. Build the digital experience that fuels driver loyalty to the IONNA network.

Requirements

Bachelor’s degree in Computer Science or a related field, or equivalent practical experience.
A minimum of 3 years of professional experience as a full stack developer building and shipping web applications.
Strong proficiency in React and TypeScript for frontend development.
Experience with Node.js and server-side TypeScript or JavaScript for backend development.
Familiarity with Next.js or similar React-based frameworks.
Experience designing and consuming RESTful APIs.
Comfortable working with relational databases (schema design, queries, migrations).
Proficient with Git and collaborative development workflows (pull requests, branching strategies).
Experience with or willingness to adopt AI-powered development tools (e.g., Claude, GitHub Copilot) as a core part of your engineering workflow.
Effective communication skills and ability to work effectively in a small, collaborative team.
Ability to work independently, manage your own priorities, and deliver reliably in a fast-paced environment.
Experience working within agile development practices.

Nice To Haves

Experience with SQL and database engineering (writing complex queries, optimizing performance, managing schemas at scale).
Familiarity with Python for scripting, data processing, or backend services.
Experience with cloud infrastructure (AWS) and containerization tools (Docker, Kubernetes).
Familiarity with CI/CD tools and DevOps practices.
Exposure to payment processing flows or e-commerce promotional systems.
Knowledge of the EV charging industry, including standards like OCPP, ISO 15118, or OCPI.
Experience building consumer-facing products with a focus on user experience and mobile-first design.

Responsibilities

Develop and ship features end-to-end across the IONNA stack.
Collaborate with the team to translate product requirements into technical designs and working software.
Integrate with third-party systems including EV charge point management APIs and payment processing workflows.
Write clean, tested, well-documented code and participate in code reviews.
Use AI-assisted development tools (such as Claude) as part of your daily workflow to accelerate development, improve code quality, and solve complex problems.
Contribute to CI/CD pipelines, deployment processes, and development environment improvements.
Troubleshoot and debug issues across the full stack, from UI rendering to API integrations to database queries.
Help shape technical decisions and architecture as the platform grows.
