Job description

About this position:

Join ELITS Canada’s R&D organization, where innovation, collaboration, and technical excellence shape the backbone of our cloud infrastructure. You’ll work with experienced engineers to evolve and optimize our large-scale OpenStack-based platform and its storage foundations.
We organize our work through small, agile teams focused on specific areas like IaaS, PaaS, AI & Data, and Cloud Integration. Our culture is defined by trust, self-leadership, and close collaboration between our teams in Canada and Sweden. Expect an environment that values experimentation, open communication, and continuous learning.

Responsibilities:

  • Deep-dive into Ceph code and architecture (RADOS, RGW, core storage) to optimize performance and scalability for production workloads.

  • Profile, benchmark, and troubleshoot performance issues at scale—spanning tens of petabytes and thousands of clients—to identify architectural and operational bottlenecks.

  • Lead internal knowledge development and mentorship on Ceph expertise across the IaaS and Operations teams.

  • Actively contribute upstream to the Ceph project by submitting patches, participating in design discussions, and influencing features critical to cloud provider use cases (e.g., multi-AZ, RGW performance, tiering).

  • Develop and maintain internal build pipelines and necessary extensions, ensuring compliance and long-term maintainability.

  • Partner with Platform Operations to enhance observability, maintain stability, and accelerate issue resolution in production clusters.

  • Collaborate with other squads to ensure Ceph capabilities evolve in line with upcoming roadmap items such as GPU-aaS, Backup-aaS, Bare-metal-aaS, and DB-aaS.

Requirements (Must have):

  • Proven track record operating Ceph at scale (multi-petabyte, high-availability clusters) in production environments.
    • Strong C++ development experience for system-level software, especially within Ceph core components.
    • In-depth knowledge of performance tuning (OSD placement, CRUSH maps, BlueStore tuning, cache tiering, RGW optimization).
    • Solid understanding of Linux systems engineering, networking, and storage I/O paths.
    • Proficiency with Ansible (playbooks, roles, collections) for large-scale operations and Python for custom modules, Ceph tooling, and automation workflows.
    • Hands-on experience with performance analysis tools (perf, flamegraphs, distributed tracing).
    • Familiarity with Go for building lightweight or performance-sensitive utilities is an asset.

Good to have (Merit skills):

  • Prior contributions to Ceph or other distributed storage projects (patches, reviews, or design documents).
    • Knowledge of cloud platforms such as OpenStack and their storage integrations.

Qualification:

  • • Bachelor’s degree in Engineering, Computer Science, or a related field, or equivalent experience and training.
    • Relevant technical certifications are an asset.

Qualities:

At ELITS Canada, we believe great people make great impact. Success in this role comes from curiosity, accountability, and teamwork. You bring initiative, creativity, and an engineering mindset that turns complex challenges into practical results.
You’re someone who:

  • Thrives in collaborative, cross-functional environments and communicates clearly and confidently.

  • Combines deep technical insight with hands-on problem-solving.

  • Approaches challenges with positivity, resourcefulness, and resilience.

  • Stays organized and calm when managing multiple priorities in fast-moving environments.

  • Shares knowledge generously and contributes to a culture of learning, trust, and continuous improvement.

  • Brings ideas and energy to improve products, processes, and performance.

Are you a social, flexible, and structured professional with a passion for technology and innovation? Do you enjoy exploring the limits of scalability and performance in modern cloud environments? If so, we’d love to hear from you—apply today and help us build the future of cloud storage at ELITS Canada.

This position is open to Canadian residents (persons with work permit in Canada).

  • Réaliser du profilage, des benchmarks et du dépannage de performance à grande échelle — couvrant des dizaines de pétaoctets et des milliers de clients — pour identifier les goulots d’étranglement architecturaux et opérationnels.

  • Diriger le développement interne des connaissances et le mentorat sur l’expertise Ceph au sein des équipes IaaS et Opérations.

  • Contribuer activement au projet Ceph en amont en soumettant des correctifs, en participant aux discussions de conception et en influençant les fonctionnalités essentielles aux cas d’usage des fournisseurs cloud (multi‑AZ, performance RGW, tiering, etc.).

  • Développer et maintenir les pipelines de build internes et les extensions nécessaires, en assurant la conformité et la maintenabilité à long terme.

  • Collaborer avec l’équipe Platform Operations pour améliorer l’observabilité, maintenir la stabilité et accélérer la résolution des incidents dans les clusters de production.

  • Travailler avec les autres équipes pour garantir que les capacités Ceph évoluent en fonction des éléments de la feuille de route, tels que GPU‑aaS, Backup‑aaS, Bare‑metal‑aaS et DB‑aaS.

Exigences (Essentielles)

  • Expérience démontrée dans l’exploitation de Ceph à grande échelle (clusters multi‑pétaoctets, haute disponibilité) en environnements de production.

  • Solide expérience en développement C++ pour les logiciels bas niveau, particulièrement au sein des composants centraux de Ceph.

  • Connaissance approfondie de l’optimisation des performances (placement OSD, cartes CRUSH, réglages BlueStore, cache tiering, optimisation RGW).

  • Solide compréhension de l’ingénierie des systèmes Linux, du réseautage et des chemins d’E/S de stockage.

  • Maîtrise d’Ansible (playbooks, rôles, collections) pour les opérations à grande échelle, et de Python pour les modules personnalisés, outils Ceph et automatisations.

  • Expérience pratique avec des outils d’analyse de performance (perf, flamegraphs, traçage distribué).

  • Familiarité avec Go pour la création d’utilitaires légers ou sensibles à la performance (un atout).

Atouts (Compétences souhaitées)

  • Contributions antérieures au projet Ceph ou à d’autres projets de stockage distribué (correctifs, revues, documents de conception).

  • Connaissance des plateformes cloud telles qu’OpenStack et de leurs intégrations de stockage.

Qualifications

  • Baccalauréat en génie, informatique ou dans un domaine connexe, ou expérience et formation équivalentes.

  • Les certifications techniques pertinentes sont considérées comme un atout.
