About us
Wazo builds programmable, API-first communication infrastructure and applications.We power unified communications at the infrastructure level:real-time systems, SIP signaling, Web RTC, 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 workplace includes:Backend services primarily in Python
Mobile core in Kotlin and Swift
Real-time infrastructure components across multiple technologiesFamiliarity 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 / Vo IP signaling
RTP media flows
Distributed backend systems
Event-driven architectures
Low-level networking and performance-sensitive components
AI-augmented engineering workflowsYou 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 efficiencyAI-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.

Wazo construit une infrastructure et des applications de communication programmables, API-first.Nous opérons les communications unifiées au niveau de l’infrastructure :systèmes temps réel, signalisation SIP, Web RTC, flux média, services distribués, et architectures hautement disponibles ainsi que les applications qui en découlent.Il ne s’agit pas de développement de fonctionnalités en surface.Il s’agit d’infrastructure télécom critique.Notre philosophie de recrutement
Nous recrutons des développeurs systèmes capables de raisonner dans des environnements complexes et en constante évolution. Nous attendons une forte expertise dans au moins un domaine, ainsi qu’une curiosité à opérer au-delà de celui-ci en fonction des besoins du système. Si vous préférez travailler strictement dans un cadre limité à un langage ou un framework, ce rôle peut ne pas vous convenir.Notre environnement actuel inclut :Services backend principalement en Python
Noyau mobile en Kotlin et Swift
Composants d’infrastructure temps réel sur plusieurs technologiesLa familiarité avec une stack importe moins que votre capacité à apprendre rapidement, écrire du code maintenable, et préserver l’intégrité opérationnelle. Les technologies évoluent. La pensée système, elle, reste.Le rôle
Vous travaillerez sur :Signalisation SIP / Vo IP
Flux média RTP
Systèmes backend distribués
Architectures event-driven
Composants réseau bas niveau et sensibles à la performance
