Descripción completa del empleo

We’re looking for a Senior/Lead Asterisk Developer to help us build and scale a cloud PBX solution based on Asterisk.

The team is building a cloud PBX solution based on Asterisk. We expect you to have strong problem-solving skills, be self-motivated, initiative, and responsible.

Your daily duties will include implementing different SIP proxy features using Asterisk with respect to high availability and scalability.

You are not limited to Asterisk — we welcome you to be involved in all parts of a large ecosystem built around Asterisk.

You will work with automated CI/CD processes and get a chance to improve your knowledge in cloud infrastructure and networks.

In this role, you will also:

Design and implement advanced Asterisk dialplans.
Debug and fix issues inside Asterisk core, modules, and C-based extensions.
Analyze and interpret stack traces, crashes, memory issues, and performance bottlenecks.
Implement patches, backports, or enhancements directly in Asterisk source code.
Develop custom modules (C/C++), when needed.
Apply deep understanding of SIP signaling, RTP, SDP negotiation, codecs, and NAT traversal.
Troubleshoot SIP flows.
Work with trunk groups, carriers, PSTN routing, and failover logic.
Work with Linux systems (systemd, networking, tuning, kernel parameters).
Work with Asterisk in cloud environments (AWS preferred).Participate in architecture decisions for resilient and scalable telephony clusters.

Requirements:

Have at least 7+ years of production experience with large-scale deployments (call servers with 60k+ active users).
Have contributions in https://github.com/asterisk/asterisk/.
Have experience with CI/CD, clouds, Linux & networking.
Have a good level of English (B2 or higher).
(For Lead level) Are ready to act as the technical lead for the Asterisk domain.
(For Lead level) Can work cross-team with backend developers, infra/DevOps, QA, and product owners.
(For Lead level) Own best practices, code quality, and documentation.

We are pleased to offer:

Remote work flexibility – work from anywhere.
B2B contract with competitive gross compensation in USD.
Stable job with long-term growth perspective.
Really good hardware.
An exciting and challenging job with talented people around.
Continuous learning and career growth opportunities with annual performance review.
Compensation for professional training, seminars, and conferences.
Referral program – get rewarded for helping us grow the team with talented people.
Company-supported English classes to enhance your professional growth.

We are industry leaders in prepaid communication and payment services and one of the largest international voice carriers. We are listed on the NYSE, employ over 1800 people across 20 countries, and have over $1.5 billion in revenues.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
