Backend Developer (Rust)

About Our Client

Our client is a B2B sourcing platform serving the automotive dealership industry — a small, fast-moving engineering team building core infrastructure from the ground up rather than assembling off-the-shelf tools, the kind of environment where a single engineer's technical decisions shape the product for years.

About the Role

You'll join a small engineering team building the client's sourcing platform. Your focus will be their flowgraph — a horizontally scalable, step-based execution engine, similar in spirit to n8n or Unreal Engine's Blueprints, but built from the ground up in Rust with strong typing and production workloads in mind. It drives order processing and ETL pipelines. Rather than wiring together managed queues and off-the-shelf orchestration tools, the team builds its own coordination and fault-tolerance mechanisms from scratch.

What You'll Do

• Research, design, and build on the client's bespoke distributed graph execution engine, written in Rust.
• Design and implement graph executor node implementations to power third-party integrations with partner and supplier systems.
• Build and maintain infrastructure for the distributed execution engine — deployment pipelines, observability, and site reliability.
• Design and implement coordination and fault-tolerance mechanisms from scratch, handling partial failures, node coordination, and recovery.
• Develop and maintain logistics and ETL workflows within this ecosystem.

What We're Looking For

Must-have:

• 7+ years of backend development experience, 3+ years of professional Rust experience.
• Strong, practical grasp of distributed systems and fault-tolerant software architecture.
• Familiarity with graph theory, type theory, parsers and compilers, and related CS fundamentals.
• Real-world DevOps experience.

Nice to have: A background in C/C++, experience with key-value stores (FoundationDB, TiKV), frontend web development, low-/no-code workflow tools, and WASM runtimes.

Location & Setup

Berlin/Wildau area hybrid (1 day/week in office), or fully remote within ~4–5 hours' travel of Berlin. Official employment in Germany, or B2B contract elsewhere in Europe.
