The Role
Job Title: Backend Software Engineer (Rust)
Location: Berlin, Germany
Why this role matters
As our production scheduling platform moves into active customer deployments and complex industrial integrations, our backend needs to expand rapidly to handle production workloads. You will be instrumental in scaling our core services and ensuring our software runs reliably in demanding customer infrastructure.
What You'll Do
You will own the backend services and integration pipelines that power our production scheduling platform across customer deployments.
- Build, maintain, and scale production-ready backend features and APIs in Rust.
- Implement reliable customer integrations and complex data mapping workflows.
- Collaborate closely with backend and ML teams to run workloads smoothly in production.
- Debug, test, and support robust deployments on our Kubernetes infrastructure.
- Turn bespoke customer and product requirements into clean, maintainable architecture.
What success looks like
- Month 1: Get fully up to speed with our backend codebase and integrate into our daily standups and planning workflows.
- Month 2-3: Take independent ownership of production backend features and collaborate directly on active customer integration pipelines.
- By end of Q1: Operate as a core contributor reliably shipping backend integrations and production features across customer environments.
Who This Is a Fit For
- Practical experience building applications with Rust across professional, academic, or personal projects.
- High autonomy to manage your own tasks, time, and project priorities independently.
- Strong English communication skills for close technical collaboration.
- Eagerness to dive into technical problems and learn continuously on the fly.
What it's like to work here
Flat hierarchy with low formal process and high autonomy. Team rituals center around a short daily standup and a weekly engineering planning sync, with spontaneous ad-hoc collaboration whenever questions arise. Thrives on self-direction, rapid learning on the fly, and tackling novel production challenges without rigid bureaucracy.
The offer
- High technical autonomy in a flat hierarchy with minimal formal bureaucracy.
- Direct impact shipping code to real-world industrial production environments.
- Collaborative culture with light rituals like daily standups and weekly engineering syncs.
- Broad technical scope spanning backend architecture, ML workflows, and deployment infrastructure.
