Position: Senior Software Developer / Développeur(se) Logiciel Sénior
Location: Montreal

All Together, Extraordinary

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.

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 Git Ops (Terraform, FluxCD, Git Lab 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…
