We are looking for an experienced Software Engineer to build and operate our Vehicle Grid Integration (VGI) platform, which unlocks the flexibility of electric vehicles for energy markets. This role sits at the core of our cloud infrastructure, with ownership of scalable backend services and systems running on AWS that connect EVs to the larger energy ecosystem.In this role, you will design, implement, and optimize cloud-based solutions that process data from charging infrastructure and vehicles, enabling smart charging, V2G capabilities, and energy flexibility trading. You will work closely with other engineers, product managers, and energy experts to ensure our platform is reliable, observable, and highly scalable.This role is best suited for senior-level engineers with at least 7 years of professional experience who are comfortable taking end-to-end ownership of cloud infrastructure—embracing the "you build it, you ship it, you run it" DevOps mindset.

• Develop and maintain highly scalable cloud-based backend services, primarily using Python
• Architect and optimize solutions that provide EV and charge point flexibility to energy markets
• Enhance system reliability, scalability, observability, and cost-efficiency across our AWS cloud infrastructure
• Apply software engineering best practices: modular design, design patterns, testing, CI/CD, and code reviews
• Operate containerized workloads (Docker) and integrate databases (PostgreSQL, Redis, DynamoDB) into your modern architectures
• Collaborate with cross-functional teams to translate VGI complexities (like grid constraints and charging schedules) into robust technical systems
• Implement cutting-edge technologies and uphold the highest security and quality standards for critical energy infrastructure
• Utilize TypeScript for Infrastructure-as-Code (IaC) setups and maintain some existing TypeScript backend components

• An experienced Software Engineer with at least 7 years of professional experience (excluding working student or internship positions)
• Strong expertise in Python, emphasizing clean, maintainable, and testable code
• Strong expertise in AWS cloud architecture, infrastructure best practices, and cloud-native solutions
• Strong foundation in software engineering best practices, system design, and architectural patterns
• Experience building, shipping, and running containerized applications relying on Docker
• Hands-on experience working with both relational and non-relational databases (PostgreSQL, Redis, DynamoDB)
• A DevOps mindset with a track record of owning backend systems in production environments
• Passionate about the energy transition and driven to steer the energy sector towards a greener future
• Fluent in English, both written and spoken

• Experience in e-mobility, Energy Management Systems (EMS), Vehicle Grid Integration (VGI), smart charging, or Vehicle-to-Grid (V2G)
• Familiarity with EV charging and IoT protocols (e.g., OCPP, ISO 15118, OpenADR)
• Experience with energy markets, flexibility trading, or grid integration systems
• Experience handling real-time telemetry, IoT data, or high-throughput time-series data
• Practical experience with Infrastructure-as-Code (IaC) tools on AWS (e.g., AWS CDK)Excerpt from our tech-stack, sorted by priority: Python, AWS, Docker, Rust, TypeScript, Relational and Non-Relational Databases

Diversity enriches our team and makes us stronger. Regardless of origin, gender, age, sexual orientation, religion, or any disability – everyone is welcome here! We look forward to receiving your application and achieving great things together.
