Fiber Monitoring & Network Visibility Platforms

Location: Montreal – Hybrid

About Us

We build mission‑critical fiber monitoring and network visibility platforms used by leading telecommunications operators and data center providers worldwide. Our solutions enable real‑time monitoring of fiber networks, including fault detection and localization, signal degradation analysis, and service assurance, across outside plant (OSP), data centers, and DCI environments.

Our software platform is based on a containerized microservices architecture, runs primarily on Linux, and is deployed in on‑premises, cloud, and hybrid environments. Reliability, scalability, performance, and operational excellence are at the core of what we do.

The Role

We are looking for a Senior Backend Software Developer (5–10 years of experience) to design, develop, and evolve the backend services at the heart of our fiber monitoring platforms.

You will work on distributed systems, API‑driven services, and high‑throughput data pipelines in a domain where software interfaces directly with real‑world network and hardware infrastructure. This role is ideal for someone who is curious, autonomous, and detail‑oriented, and who enjoys understanding complex systems end‑to‑end and seeing their work running in production at scale.

Key Responsibilities

Design, develop, and maintain backend services and microservices with a strong focus on performance, reliability, and resilience
Develop backend services primarily using Java, Node.js, and Go (Golang)
Design, document, and maintain robust and versioned RESTful APIs
Contribute to the evolution of a microservices architecture deployed in containerized environments
Package and deploy applications using Docker
Collaborate closely with DevOps teams to operate services in production (monitoring, logging, alerting)
Participate in architecture discussions, design reviews, and code reviews
Troubleshoot and resolve complex issues in production distributed systems
Contribute to CI/CD pipelines, automated testing, and engineering best practices
Work closely with Product, QA, and other engineers to deliver reliable and valuable features

Required Technical Skills

5–10 years of professional backend software development experience
Strong experience developing backend services using Java, Node.js, and Go (Golang) in production environments
Solid understanding of microservices architectures, including:
Proven hands‑on experience with Docker and containerized applications
Experience designing and consuming REST APIs
Comfortable working in Linux environments
Proficiency with Git and collaborative development workflows
Good understanding of concurrency, networking, and performance considerations in backend systems

Observability & Operations

Experience with logging, monitoring, and alerting in production environments
Familiarity with observability concepts and tools (metrics, distributed tracing, logs)
Ability to diagnose and analyze issues across multiple services, containers, and infrastructure layers

Assets / Nice to Have

Experience working with embedded systems or systems close to hardware
Knowledge of the C# language, particularly in system‑level tools, utilities, or backend integrations
Background in telecommunications, network monitoring, or fiber‑optic networks
Familiarity with event‑driven architectures and real‑time or near‑real‑time distributed systems
Experience with iOS and/or Android mobile development, particularly for visualization, diagnostics, or control applications, is considered an asset
Understanding or practical experience with AI coding assistants and agent‑based development tools (e.g., Cursor or similar)

Soft Skills & Mindset

Naturally curious and motivated to deeply understand how systems behave in production
Self‑driven and autonomous, able to own features from design through deployment
Strong analytical and problem‑solving skills
Clear communicator, comfortable collaborating across teams
High standards for quality and a strong sense of ownership for production systems
Team‑oriented with a proactive attitude

Requirements

Bachelor’s degree in Software Engineering, Computer Science, or equivalent professional experience
Working or fluent English required (French is a strong asset)
Legal authorization to work in Canada

What We Offer

Competitive salary and comprehensive benefits package
Hybrid and flexible work environment
Opportunity to work on real‑world infrastructure at global scale
Collaborative, pragmatic engineering culture
Long‑term product roadmap with meaningful technical challenges
Continuous learning and professional growth opportunities

Job Description

Plateformes de surveillance de fibres optiques et de visibilité réseau

Lieu : Montréal – Hybride

À propos de nous

Nous concevons des plateformes logicielles critiques de surveillance de fibres optiques et de visibilité réseau, utilisées par des opérateurs télécoms et des fournisseurs de centres de données à travers le monde. Nos solutions permettent la surveillance en temps réel des réseaux fibre, incluant la détection et la localisation de pannes, l’analyse de dégradations de signal et l’assurance de service, tant pour les réseaux extérieurs (OSP) que pour les centres de données et les interconnexions DCI.

Notre écosystème logiciel repose sur une architecture de microservices conteneurisés, s’exécute principalement sous Linux et est déployé dans des environnements on‑premise, cloud et hybrides. La fiabilité, la performance, la scalabilité et l’excellence opérationnelle sont au cœur de notre ADN.

Le rôle

Nous recherchons un développeur backend senior (5 à 10 ans d’expérience) afin de concevoir, développer et faire évoluer les services backend au cœur de nos plateformes de surveillance de fibres optiques.

Vous travaillerez sur des systèmes distribués, des services orientés API et des pipelines de données à haut débit, dans un contexte où le logiciel interagit directement avec des infrastructures réseau et matérielles réelles. Ce rôle s’adresse à une personne curieuse, autonome et rigoureuse, qui souhaite comprendre des systèmes complexes de bout en bout et dont les livrables sont utilisés en production à grande échelle.

Responsabilités principales

Concevoir, développer et maintenir des services backend et microservices avec un fort accent sur la performance, la fiabilité et la résilience
Développer des services principalement en Java, Node.js et Go (Golang)
Concevoir, documenter et maintenir des API REST robustes et versionnées
Contribuer à l’évolution d’une architecture microservices déployée dans des environnements conteneurisés
Conteneuriser et déployer les applications à l’aide de Docker
Collaborer étroitement avec les équipes DevOps pour l’exploitation des services en production (monitoring, logs, alertes)
Participer aux décisions d’architecture, aux revues de conception et aux revues de code
Diagnostiquer et résoudre des problèmes complexes dans des systèmes distribués en production
Contribuer aux pipelines CI/CD, aux tests automatisés et aux bonnes pratiques d’ingénierie
Travailler en collaboration avec les équipes Produit, QA et d’autres développeurs afin de livrer des fonctionnalités de grande valeur

Compétences techniques requises

5 à 10 ans d’expérience professionnelle en développement backend
Solide expérience en Java, Node.js et Go (Golang) pour le développement de services backend en production
Très bonne compréhension des architectures microservices, incluant :

La définition et la responsabilité des frontières de services
Les patterns de communication inter‑services
La conception, le versionnement et la gouvernance des API
Les notions de scalabilité, de résilience et de tolérance aux pannes

Expérience pratique confirmée avec Docker et les applications conteneurisées
Expérience dans le développement et la consommation d’API REST
À l’aise dans des environnements Linux
Maîtrise de Git et des flux de développement collaboratif
Bonne compréhension des enjeux de concurrence, réseau et performance des systèmes backend

Observabilité et exploitation

Expérience avec la journalisation, la surveillance et les alertes en environnement de production
Familiarité avec les concepts et outils d’observabilité (métriques, traces distribuées, logs)
Capacité à analyser et diagnostiquer des problèmes impliquant plusieurs services, conteneurs et couches d’infrastructure

Atouts appréciés

Expérience avec des systèmes embarqués (embedded systems) ou des environnements proches du matériel
Connaissance du langage C#, notamment dans des contextes orientés systèmes, outils ou intégrations backend
Expérience dans les domaines des télécommunications, de la surveillance réseau ou des réseaux à fibres optiques
