Senior Platform Engineer - AWS - Team Platform (d/f/m)

Kurz zusammengefasst

Bettermile is a fast‑growing SaaS company that modernises last‑mile logistics with a geo‑based, AI‑driven platform for address processing, dynamic routing and navigation. The Senior Platform Engineer will join the Platform team, which supplies the shared infrastructure, authentication, observability and developer tooling that lets product squads ship, run and secure their services quickly. On a day‑to‑day basis the role blends hands‑on engineering (about 60 % of the time) with strategic work and mentorship (about 40 %). You will drive the evolution and stability of the central authentication layer, own the observability, scalability, security and cost‑efficiency of the whole infrastructure, and implement infrastructure‑as‑code across the ecosystem. In addition, you will guide senior platform engineers, promote a DevOps culture, and help shape platform‑engineering best practices while collaborating closely with product teams and other stakeholders. The position requires deep, practical experience with Amazon Web Services, including services such as CDK, EC2, ECS, S3, EventBridge, SQS, Location Services and API Gateway.

The role offers a supportive, diverse environment with flat hierarchy, autonomy, professional growth, hybrid flexibility, up to 12 weeks of remote work per year, 30 vacation days, a kindergarten grant, pension scheme and regular wellness activities in a modern Berlin office.
