Senior DevOps Engineer (m/f/d) SpiNNcloud Systems GmbH

(Senior) DevOps Engineer – Build Systems & Monorepo

About SpiNNcloud

SpiNNcloud Systems is a pioneering deep-tech company developing brain inspired computing hardware and software based on the SpiNNaker2 architecture. Our Hardware-as-a-Service platform provides researchers and enterprises with remote access to cutting-edge neuromorphic computing resources, enabling breakthroughs in AI, brain simulation, and energy-efficient computing.

Role Overview

We are seeking an experienced DevOps Engineer to lead our transition to a monorepo architecture and establish world-class build and CI/CD infrastructure. This is a high-impact role where you will architect and implement the build systems that enable several engineering teams to collaborate efficiently across C/C++, Python, Go, and embedded firmware projects.

You will be optimizing build times, establishing caching strategies, and creating the tooling that accelerates our engineering velocity.

Key Responsibilities

Monorepo Migration & Architecture

• Lead the migration of 10+ projects into a unified monorepo structure with clear ownership boundaries
• Design and implement the dependency graph system that determines build/test scope for each commit
• Establish project templates, CODEOWNERS policies, and contribution workflows
• Create documentation aggregation pipelines (MkDocs) for unified developer documentation

Build Systems & CI/CD

• Architect GitLab CI pipelines with intelligent change detection and targeted builds
• Optimize CMake build configurations for multi-toolchain support (GCC, Clang, ARM cross-compilation)
• Implement and maintain sccache with Redis backend for distributed C++ compile caching
• Configure Python build tooling (uv, scikit-build-core) for native extension packaging
• Reduce incremental build times through strategic caching

Artifact & Release Management

• Manage GitLab Package Registries (PyPI, Conan, Container, Generic) for internal artifact distribution
• Implement semantic versioning and release automation across all project types

Infrastructure & Platform

• Maintain GitLab Runner infrastructure
• Manage cache infrastructure (Redis clusters for sccache, GitLab caching)
• Monitor CI/CD metrics and continuously optimize pipeline performance
• Collaborate with Platform team on deployment pipelines

Developer Experience

• Create and maintain developer tooling, CLI utilities, and local development environments
• Write documentation for build systems, workflows, and troubleshooting
• Provide support and training to engineering teams on monorepo best practices
• Champion build system improvements and gather feedback from development teams

Required Qualifications

Experience

• 5+ years in DevOps, Build Engineering, or Platform Engineering roles
• 3+ years hands-on experience with GitLab CI/CD (pipelines, runners, artifacts)
• Experience managing monorepo or large-scale multi-project repositories
• Track record of reducing build times and improving developer productivity

Technical Skills

• Expert-level CMake knowledge (presets, toolchains, cross-compilation)
• Strong C/C++ build chain understanding (GCC, Clang, linkers, static/shared libraries)
• Python packaging ecosystem (pip, uv, wheels, setuptools, scikit-build-core, pybind11)
• Distributed caching systems (sccache, ccache, Redis)
• Containerization (Docker, multi-stage builds, BuildKit, container registries)
• Linux systems administration and shell scripting (Bash)
• Git advanced workflows (submodules, sparse checkout, partial clone)

Preferred Qualifications

• Experience with ARM embedded toolchains (arm-none-eabi-gcc, bare-metal development)
• Conan package manager for C++ dependency management
• Kubernetes (deployment, Helm, operators) — our runners use K8s executors
• Go build toolchain and module system
• JavaScript/TypeScript build tools (pnpm, Vite, esbuild)
• Familiarity with Bazel (for future evaluation, not immediate requirement)
• Experience in hardware or embedded systems companies
• Strong communication level of English language

What We Offer

• Competitive salary based on experience
• Equity participation in a growing deep-tech company
• Flexible hybrid work arrangement (3 days office / 2 days remote)
• 30 days annual vacation
• Work on cutting-edge neuromorphic computing technology
• High-impact role with direct influence on engineering productivity
• Collaborative team culture with experienced engineers from academia and industry

Technology Stack You Will Work With

• CI/CD – GitLab CI, GitLab Runners (Kubernetes executor)
• Build Systems – CMake, Conan, uv, pybind11, scikit-build-core
• Languages – C, C++, Python, Go, Bash, YAML
• Compilers – GCC, Clang/LLVM, arm-none-eabi-gcc
• Caching – sccache, Redis, GitLab cache
• Containers – Docker, BuildKit, GitLab Container Registry
• Infrastructure – Kubernetes (RKE2), Linux (Ubuntu)
• Documentation – MkDocs, Markdown, Doxygen
