# Backend Developer (Rust)

**OnHires** · Berlin

Apply: https://jobs.ashbyhq.com/onhires/cacdeec8-9c8c-4206-831c-7ac56266ec1a

## About OnHires

Global recruitment from OnHires tailored solutions for your business needs. A remote recruiter will find you specialists professionally and quickly.

## About the role

### Rust Engineer — Distributed Execution Engine

Berlin (hybrid) or Remote (countries within ~4–5 hours travel of Berlin)

#### About our client

Our client is a B2B sourcing platform serving the automotive dealership industry. They're 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 their order processing and ETL pipelines.

This isn't a typical backend role. Rather than wiring together managed queues and off-the-shelf orchestration tools, the team **builds its own coordination and fault-tolerance mechanisms from scratch** — because the workloads don't fit neatly into existing solutions. If you enjoy thinking about **graph theory, type systems, parsers and compilers, WASM runtimes, or distributed systems architecture** as part of your everyday work — not just as a personal interest — you'll feel at home here.

#### 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 (not by wrapping existing message queues) — handling partial failures, node coordination, and recovery within the engine itself.

- Develop and maintain logistics and ETL workflows within this ecosystem, tied directly to the core business.

#### 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 at least some of: graph theory, type theory, parsers and compilers, and related CS fundamentals. We don't expect mastery of all of these — most strong candidates bring deep expertise in 3–4 out of 5 core areas, with distributed systems being the one we weight most heavily.

- Real-world DevOps experience.**Nice to have:**

- A background in C/C++ before moving to Rust.

- Experience with key-value stores or distributed databases — FoundationDB or TiKV are a big plus.

- Experience with frontend web development.

- Experience with existing low-/no-code workflow tools (n8n, Prefect, AWS Step Functions).

- Understanding of WASM runtimes.

- Previous experience with logistics or process management systems.

#### Location & setup

- Berlin / Wildau area: hybrid, with 1 day per week in the office.

- Elsewhere within ~4–5 hours' travel of Berlin: fully remote, no office requirement.

- Employment: official employment in Germany, or B2B contract elsewhere in Europe.

- Full-time, ~40 hours/week, with meaningful overlap with CEST hours.
