About Stellar

Stellar brings together professionals and experts from a range of exciting domains and technologies: telecommunications (cellular 4G/5G terrestrial and non-terrestrial networks, Wi‑Fi and satellites), mobility (trains, aircraft, drones and road vehicles), and software for efficient data transmission, orchestration, network management, data collection, processing and analysis, including growing AI/ML capabilities. Our products and solutions - the STEER® Software Suite, M2M/IoT solutions and the all-in-one GLOBBLE® offering - are transforming how people and vehicles experience connectivity while on the move by enabling seamless, ubiquitous and reliable broadband services. More information is available at https://www.stellar.tc. Stellar is an ideal workplace for professionals who are eager to learn, challenge conventional approaches, explore practical innovations and take meaningful ownership in a supportive, collaborative, results‑driven, international and professional environment.

Position Summary

Reporting to the Director of Software Development, the Senior DevOps Engineer owns the deployment pipelines, containerized environments and software release lifecycle for Stellar's STEER® software suite across lab, dev and production environments. This is an individual contributor role focused on hands‑on technical execution. The role spans release engineering, containerized deployment and the day‑to‑day operation of the CI/CD and collaboration platforms, in close partnership with the Infrastructure & Network Engineer, who owns the underlying platform (physical network, virtualization host cluster, storage, backups and identity services). Scope note: The DevOps Engineer administers guest operating systems, hosted applications, containers and software release pipelines, whether running on‑premises or on production cloud VPS. The Infrastructure & Network Engineer provisions and secures the platform; the DevOps Engineer deploys and operates what runs on it.

Key Responsibilities

• CI/CD & Release Engineering Design, build and maintain CI/CD pipelines using GitLab CI (or equivalent) to automate build, test and deployment workflows. Own and administer the CI/CD and collaboration platforms (GitLab and related tooling), including updates, runners, access and maintenance. Manage the deployment of STEER® software releases across lab, dev and production environments, including controlled rollout, rollback procedures and release documentation.
• Containerization & Configuration Management Manage the Docker Swarm cluster that runs the application workloads, including the multi-service STEER Management stack (Django, Channels, Celery, Redis and PostgreSQL). Use Ansible to provision and configure the operating systems and applications on the machines that make up a deployment (management server, gateway and VPS with VPN connectivity), maintained as infrastructure-as-code across several repositories. Administer application-level configuration, patching and lifecycle inside VMs, coordinating with the Infrastructure & Network Engineer for any platform-level change.
• Production Cloud VPS Administer the guest operating system and application layer of Stellar's production cloud VPS: hardening, patching and configuration. Deploy and operate STEER® software releases on cloud VPS, following the same lab/dev/prod promotion process used for on-premises environments. Coordinate with the Infrastructure & Network Engineer on the network and security perimeter of these VPS (firewall rules, security groups, VPN and remote access); provider account access (billing, account-level IAM, provider selection) is managed separately by company management.
• Monitoring & Observability Implement and maintain application-level monitoring and logging, complementing the infrastructure-level monitoring already in place. Define alerting and dashboards for deployment health, service performance and release quality. Setup and operate secrets management for pipelines and deployments (credential storage, distribution, and rotation), shared with the Infrastructure & Network Engineer.
• Collaboration & Documentation Partner with software engineers, product and operations teams to align deployment practices with product roadmaps. Maintain clear documentation for pipelines, deployment procedures and release runbooks. Share DevOps best practices across the engineering organization.

Required Experience and Skills

• 5+ years of hands‑on experience in a DevOps role, ideally within a high‑growth software or telecommunications company.
• Strong Linux administration skills (Debian a plus, matching Stellar's infrastructure stack).
• Production experience with Docker.
• Hands‑on experience with Ansible or equivalent configuration management / IaC tooling.
• Experience designing and maintaining CI/CD pipelines (GitLab CI or equivalent).
• Scripting proficiency in Python and Shell.
• Experience managing software releases across multiple environments (lab, dev, staging, production).
• Experience with secrets management for CI/CD and production deployments.
• Familiarity with private cloud and VPS environments (Stellar's primary setup) and with major public clouds (AWS, Azure, GCP), which some customer deployments require.
• Agile mindset and comfort working closely with an Infrastructure & Network Engineer on shared platform dependencies.
• Professional proficiency in English (French a plus).

Preferred Experience

• Experience with embedded or constrained Linux environments (e.g. OpenWrt) relevant to edge deployments.
• Experience with application‑level observability tooling (e.g. Prometheus or Grafana).
• Prior experience in telecommunications, satellite or mobility connectivity products.

What We Offer

• Strong technical ownership over Stellar's software release and deployment lifecycle.
• Direct, visible impact on the reliability and velocity of STEER® releases.
• Exposure to telecommunications, mobility, edge computing and connected systems.
• Continuous learning in a supportive, expert-driven engineering team.
• A collaborative, international and multicultural working environment.
• A competitive compensation package, including Stellar stock options.
