Shape the future of a large-scale cloud platform for e-mobility
At vaylens, you'll architect one of the leading SaaS platforms in the rapidly growing e-mobility industry. Our platform consists of 80+ cloud-native applications and microservices powering business portals, mobile apps, and digital services that enable the operation of charging infrastructure across Europe.
As the market evolves at high speed, so does our platform. New products, integrations, and services, increasing data volumes, demanding performance requirements, and evolving customer expectations continuously create exciting architectural challenges. This is where you come in.

Working closely with Product Management, Engineering, DevOps, and the Head of Platform Architecture, you'll influence our technical direction, lead strategic architecture initiatives, and help engineering teams solve complex distributed systems challenges. If you enjoy balancing big-picture architecture with hands-on technical discussions-and want to leave your fingerprint on a platform operating at scale-this role is for you.
Your responsibilities

- Lead architectural initiatives such as platform modernization, migrations, third-party integrations, and Proofs of Concept for emerging technologies.
- Evaluate technologies, frameworks, and architectural patterns to continuously evolve our technology landscape.
- Provide architectural guidance to engineering teams, conduct architecture reviews, and ensure compliance with engineering, security, and quality standards.
- Act as a trusted sparring partner for the Head of Platform Architecture, Product Owners, Software Project Managers, and engineering teams on strategic technology decisions.
- Mentor engineers and architects, foster technical excellence, and contribute to a strong engineering culture.
- Support Sales and Customer Success by designing customer-specific solution and migration concepts for enterprise customers.

- Strong analytical and problem-solving skills with the ability to evaluate architectural trade-offs and make sustainable technology decisions.
- Excellent communication and stakeholder management skills, with the ability to explain complex technical concepts to different audiences.
- Experience working in agile development environments; experience with SAFe is an advantage.
