Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Backend Developer (Rust) - **Company:** OnHires - **Location:** Berlin, Germany - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** Amazon Web Services, C++ (Programming Language), Compilers, Extract Transform Load (ETL), DevOps, Web Development, Distributed Data Store, Distributed Systems, Fault Tolerance, Graph Theory, Parsing, Software Architecture, Queueing Systems, Reliability Engineering, Type Systems, Delivery Pipeline, Backend, Front End Software Development, Unreal Engine - **Published:** September 18, 2026 - **Apply:** https://www.adzuna.de/details/5886412947 ## About the Role 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. ## Description 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. ## Related Videos - [Get ready to Rustle](https://www.wearedevelopers.com/videos/698-get-ready-to-rustle) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Tips and Tricks for Working with JSON](https://www.wearedevelopers.com/videos/1229-tips-and-tricks-for-working-with-json) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Rust Beyond Systems: Revolutionizing Web Development](https://www.wearedevelopers.com/videos/1111-rust-beyond-systems-revolutionizing-web-development) ## Related Articles - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers)
