About us

Wazo builds programmable, API-first communication infrastructure and applications.

We power unified communications at the infrastructure level:

real-time systems, SIP signaling, WebRTC, media flows, distributed services, and high-availability architectures and applications based on those.

This is not feature-layer work.

This is mission-critical telecom infrastructure.

Our Hiring Philosophy

We hire systems engineers who can reason about complex, evolving environments. We expect strong depth in at least one domain, and the curiosity to operate beyond it as the system demands. If you prefer working strictly within a single framework or language, this role may feel constrained.

Our current environment includes:

• Backend services primarily in Python
• Mobile core in Kotlin and Swift
• Real-time infrastructure components across multiple technologies

Familiarity matters less than your ability to learn quickly, write maintainable systems code, and protect operational integrity. Technology choices evolve. System thinking does not.

The Role

You will work on:

• SIP / VoIP signaling
• RTP media flows
• Distributed backend systems
• Event-driven architectures
• Low-level networking and performance-sensitive components
• AI-augmented engineering workflows

You will contribute across layers — from protocol handling to API orchestration.

You will own:

• Architecture: clean interfaces between protocol handling, media, and API layers
• Reliability & operability: instrumentation, debugging, incident follow-ups, hardening
• Performance: latency, throughput, resource usage, media path efficiency
  
  

AI-Native Engineering

We operate with an agent-centric model. AI is used to accelerate execution (drafts, refactors, tests, runbooks), but humans own correctness.

You will provide direction, constraints, validation, and long-term coherence. You will set constraints, review outputs critically, and ensure changes align with long-term architecture. AI assists with drafting, refactoring, tests, and documentation.

The bottleneck is judgment.

We are looking for engineers who can supervise quality, protect architectural integrity, and make sound trade-offs at scale

What We’re Looking For

• 10+ years of professional experience (6–10 considered for exceptional system-level profiles)
• Strong system thinking is required
• Experience in distributed or real-time systems
• Comfort near infrastructure layers
• Autonomous, high-ownership mindset
• Product awareness
• Telecom experience is a plus. Systems thinking is essential.
• Engineering school background

Compensation & Benefits

Compensation and benefits for this role are calibrated against the specific local market standards to ensure competitive alignment with regional cost-of-labor and talent benchmarks

We reward depth, ownership, and architectural impact.

Benefits offered

• Permanent full-time position – Canada from Ontario to east cost as the company is between Europe and North America
• Comprehensive benefits package covered by the employer
• Competitive salary
• 4 weeks of vacation + comfort days
• Remote work – with the option to work in the Quebec City office
• VRSP (independent contractor)
• Friendly culture with great opportunities to make an impact on a growing global team.
  
  

Why Join

• Fast growing and changing environment
• AI-native engineering model
• Infrastructure-level challenges
• High autonomy
• Senior, high-density team

If you value judgment, system integrity, and meaningful technical impact — we should talk.
