Senior Software Developer / Développeur Logiciel Sénior

All Together, Extraordinary

www.adunaglobal.com

At Aduna, we’re building the backbone of the global API economy - connecting telecom operators, cloud platforms, and software innovators to enable the next generation of digital communication services.

As a Senior Software Developer on the Traffic Plane team, you will be a key technical contributor for the systems connecting Aduna to CSP Service Exposure APIs, aggregating and exposing Aduna APIs to Application Service Providers. You’ll contribute to architecture decisions, lead complex engineering work, and collaborate closely with Engineering, Product, SRE, Security, and external CSP counterparts.

This is a hands-on technical role with meaningful influence on system design and engineering standards - no people management, but active participation in technical discussions, mentorship of junior engineers, and cross-team collaboration are expected.

What You’ll Do

Technical Leadership & Architecture

Contribute to the technical direction and architectural decisions for Aduna’s API aggregation
Participate in and lead design reviews for API aggregation: Service Exposure connectors, Authentication and Authorization, observability, logging, security and metering.
Apply and help evolve technical standards and best practices; evaluate new technologies and propose improvements to the API aggregation.
Identify risks and contribute to architectural improvements addressing scalability, resilience, and operational complexity.

Complex Problem Solving & Delivery

Tackle complex technical problems spanning Aduna services, CSP Service APIs, and external partners; contribute to incident investigations and drive corrective actions to completion.
Optimize end-to-end request flows, identify performance bottlenecks, and evolve the architecture for high throughput and low latency.
Collaborate with Product to translate business goals into technical solutions; improve developer productivity through better tooling, CI/CD, and automation.

Mentorship & Technical Culture

Mentor engineers on system design, operational excellence, and technical decision making.
Raise the engineering bar through code reviews, design feedback, knowledge sharing, and promoting rigor in testing, observability, and security.

What You Bring

5+ years building and operating backend services, distributed systems, or large-scale integrations in production
Experience as a Senior Developer or equivalent technical role at a technology company
Track record of delivering meaningful technical initiatives with availability, performance, and security requirements
Experience integrating with telecom service API
Background in SRE, DevOps, or infrastructure engineering
Strong expertise in backend and integration design: service-to-service communication, data consistency, idempotency, and resiliency patterns (retries, circuit breakers, backpressure)
Proficiency in at least one backend language such as Go, Java, or Python
Experience with cloud platforms (Azure, AWS), Kubernetes, Service Meshes like Istio, Caches like Redis and message brokers (Kafka or similar)
Expertise in optimizing ELK Stack (Elastic Search, Log Stash, Kibana)
Hands-on experience with infrastructure as code, CI/CD, and GitOps (Terraform, FluxCD, GitLab CI or similar)
Strong understanding of observability, SLOs, capacity planning, and performance engineering
Expertise to identify and solve performance bottlenecks for high throughput systems
Excellent communication skills across engineering, product, and executive audiences
Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience

✨ Bonus

Experience with telecom industry
Experience with API management platforms, identity systems, and policy enforcement
Exposure to OpenAPI, CAMARA, or similar standards-driven ecosystems

🌟 Why Join Aduna?

Impactful Work: Shape cutting-edge digital platforms that millions will rely on
Innovative Culture: High ownership, collaboration, and learning
Growth & Flexibility: modern tools, and work-life balance

Our Offer:

Hybrid model: 2-3 days/week in the Montreal office
Competitive salary and full benefits (dental & medical, RRSP/DPSP)
Unlimited paid time off

Optimiser les flux de requêtes de bout en bout, identifier les goulots d’étranglement en termes de performance, et faire évoluer l’architecture pour un haut débit et une faible latence.
Collaborer avec l’équipe Produit pour traduire les objectifs métier en solutions techniques ; améliorer la productivité des développeurs grâce à de meilleurs outils, à l’intégration continue/déploiement continu (CI/CD) et à l’automatisation.

Mentorat et culture technique

Soutenir et accompagner les ingénieurs juniors dans la conception de systèmes, l’excellence opérationnelle et la prise de décision technique.
Élever le niveau d’ingénierie par des revues de code, des retours sur la conception et la promotion de la rigueur en tests, observabilité et sécurité.

Ce que vous apportez

5+ ans dans la conception et l’exploitation de services backend, systèmes distribués ou intégrations à grande échelle en production
Expérience en tant que Développeur Sénior ou dans un rôle technique équivalent au sein d’une entreprise technologique
Bilan de réalisation d’initiatives techniques significatives avec des exigences de disponibilité, de performance et de sécurité
Expérience dans l’intégration d’APIs de services télécom

Expérience avec l’infrastructure en tant que code, CI/CD et GitOps (Terraform, FluxCD, GitLab CI ou similaire)
Solide compréhension de l’observabilité, des SLO, de la planification de capacité et de l’ingénierie des performances
Expertise dans l’identification et la résolution des goulots d’étranglement de performance pour les systèmes à haut débit
Excellentes compétences en communication auprès des équipes ingénierie, produit et direction
Licence en informatique, ingénierie ou expérience pratique équivalente

✨ Bonus

Expérience avec l’industrie des télécommunications
Expérience avec les plateformes de gestion des API, systèmes d’identité et application des politiques
Familiarité avec OpenAPI, CAMARA ou écosystèmes similaires
