Product Engineer

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
