The listing
The Senior C/C++ Engineer sits within Omilia's product engineering team, building and maintaining performance-critical systems software that underpins Omilia's conversational AI infrastructure. The role requires strong systems-level programming fundamentals and, ideally, prior exposure to telephony or real-time communications stacks such as Asterisk-based voice platforms, SIP signaling, and dialplan engineering. It is structured to let a strong C/C++ engineer grow into deep telephony specialization over time, with mentorship available from the team's existing SIP experts. Engineers who already bring that expertise are fast-tracked into the specialized workstreams.
Accountabilities
- Own the design, development, and ongoing support of performance-critical C/C++ components across Omilia's platform.
- Own resolution of scalability and performance issues affecting telephony and SIP systems.
- Ensure effective time management and consistent delivery against deadlines.
- Contribute as an integrated, collaborative team member across engineering and cross-functional teams.
Key Responsibilities
- Design, implement, and maintain C/C++ components across Omilia's platform, with emphasis on performance, memory safety, and concurrency correctness in production systems.
- Develop efficient applications for mission-critical systems geared for high availability and performance.
- Debug complex, multi-threaded, low-level issues using tools such as gdb, valgrind, and/or strace.
- Develop, extend, and maintain custom Asterisk modules (res_, chan_, app_*) to support call handling, recording, and routing requirements specific to the platform.
- Patch, rebuild, and validate Asterisk core and third-party modules against upstream security advisories and internal hardening requirements.
- Identify performance bottlenecks and suggest improvements.
- Develop with security principles in mind and scale services with a DevOps mindset.
- Meet regularly with the line manager to review progress; manage issue resolution and escalate critically when needed.
- Work effectively with other teams, units, and departments, ensuring clear information flow and team working.
- Support other organisational priority activities when necessary, and act as an Omilia ambassador.
Requirements
Required:
- 5+ years professional experience in C/C++ systems programming, including memory management, multithreading, and low-level debugging.
- Experience with Git and C/C++ build systems such as CMake or Meson.
- Hands-on experience modifying, compiling, and deploying Asterisk.
- Experience writing APIs and/or Web Services & Microservices using C/C++.
- Object-oriented analysis and design using common design patterns.
- Self-motivated and driven to create extraordinary things.
- Ability to work under pressure and on strict deadlines.
- Bachelor's degree in Computer Science.
- Very good written and oral communication skills in English.
- Continuous innovation mindset.
Nice to have:
- Knowledge of SIP (RFC 3261) and related RFCs (SDP, RTP/RTCP, STUN/TURN/ICE) and practical dialplan authoring experience.
- Experience with Java or Python programming.
- Familiarity with FreeSWITCH, Kamailio, or OpenSIPS, WebRTC-to-SIP interworking, or call recording/audio codec architectures (G.711, G.729, Opus).
- Experience in regulated environments (PCI-DSS, HIPAA) where call recording and redaction requirements apply.
Benefits
- Fixed compensation;
- Long-term employment with the working days vacation;
- Development in professional growth (courses, training, etc);
- Being part of successful cutting-edge technology products that are making a global impact in the service industry;
- Proficient and fun-to-work-with colleagues;
- Apple gear
