Industry: Telecommunications / Mobile Networks
Primary Stack: Rust, Linux, PostgreSQL, Docker, Angular/TypeScript
Additional Technologies: C/C++, SIP, SMPP, Diameter, GTP, HTTP APIs, AI-assisted development

About the Role

VINOC is looking for a strong Rust / Systems Engineer to work directly on the development of our mobile telecommunications core and supporting platforms.

This is not a traditional CRUD or frontend-focused position. You will work on real network infrastructure handling mobile subscribers, signaling, data sessions, voice, SMS, charging, routing, and network integrations.

Our systems include components around 4G/LTE EPC, 5G Core, IMS/VoIP, SMS, Diameter, GTP, SMPP, subscriber management, charging, and network automation.

You do not need to already be a telecom expert. We care more about strong engineering fundamentals, curiosity, the ability to understand protocols, and the ability to learn an unfamiliar system quickly.

We are looking for a practical engineer who enjoys building things, debugging difficult problems, reading protocol specifications,



analyzing packet captures and logs, and taking ownership of working software.

AI-assisted development is part of our workflow. We expect engineers to be comfortable using tools such as Claude Code, Codex, Cursor, or GitHub Copilot to increase productivity while still understanding, reviewing, testing, and taking responsibility for the code they produce.

What You’ll Work On

You may contribute to systems such as:
- Mobile core network components and supporting services for 4G/LTE and 5G
- High-performance asynchronous network services written in Rust
- Telecom protocols and integrations including Diameter, GTP, SIP, SMPP, HTTP/REST and WebSockets
- Subscriber authentication, provisioning and session management
- Online charging, quotas, policy control and billing integrations
- SMS and voice infrastructure
- IMS and VoIP services
- Network routing and service discovery
- Internal APIs and microservic
